Modash gives brands the tools to work with the right content creators and helps creators earn a living doing what they love. Behind the scenes, we’re building the world-class data platform that powers creator discovery for thousands of companies — and we’re looking for a hardened Senior Search Engineer to shape the direction of the creator economy.

🚀 What your day-to-day will look like

We’re not a service function — Data & Backend Engineering are core product capabilities at Modash, building products for customers to use. Search is a specialised sub-team of backend engineering, and you’ll own projects end-to-end, from idea to launch.

Here’s a typical day:

Start your day with a short standup
Heads-down focus time to design, build, and optimise large-scale search systems
Minimal meetings — maximum ownership
Collaborating with backend, data, and product teams to deliver impactful features
Continuously improving search accuracy, speed, and scalability

You’ll be working on big, impactful projects like:

Building a creator search engine indexing 200M+ influencer profiles and billions of media files
Generating embeddings from images, videos, text, and audio at massive scale
Creating systems for advanced filtering, ranking, and relevance scoring
Deploying the latest ML models for semantic and vector search into production within weeks
Designing indexing and querying pipelines to serve millions of requests with low latency
Experimenting with how LLMs, multimodal embeddings, and vector databases can enhance search & recommendations

You won’t be patching pipelines — you’ll be creating production-ready search products from scratch that directly impact customers.

👥 The Data Team

At Modash, search is a joint effort between the data and backend engineering teams. You’ll work closely with:

We work in two closely aligned teams:

Data Engineering – building the ingestion, processing, and enrichment pipelines that feed our search systems.
Backend Engineering – integrating search into our APIs, infrastructure, and customer-facing features.

We value autonomy, but we also love to work closely as a team — through pair programming, reviews, and shared wins. You’ll collaborate with the CEO, CTO, engineers, sales, and even customers to shape what we build. Everyone takes ownership, but nobody works in isolation.

We’re remote-first, but we connect IRL at regular team offsites to collaborate, reflect, and have fun.

⚙️ Our tech stack

AWS with Pulumi (IaC)
Typescript and Node.js
ElasticSearch
Airflow for orchestration
Spark (EMR) — mostly PySpark
SageMaker, DynamoDB, S3, Glue, Kinesis, Lambda, ECS
GitHub, Confluence, Miro, Jira

🧪 The interview process

We move fast. You can get interviewed in under a week. Process consists of:

1. Intro chat

2. System Design Interview (search and influencer related)

3. Team Interview

3. Culture & alignment call with the CEO Avery Schrader - That’s it!

Requirements

🛠 Skillset we’re looking for

Solid experience as a Backend or Data Engineer with a focus on search systems at big-data scale
Deep expertise with Elasticsearch or comparable search technologies
Experience with vector search, embeddings, semantic search, and ranking algorithms
Proven track record designing & scaling indexing and querying pipelines
Familiarity with AWS (SageMaker, Glue, Kinesis, SQS, Lambda, ECS)
You’ve built full products from concept to production: scoping → architecture → implementation → release
Strong system design skills and experience with large-scale, high-volume environments
Clear communication skills & collaborative mindset
Autonomy in gathering requirements for complex projects
Experience in fast-paced startup environments
Based in Europe with some overlap with GMT+3

✅ Bonus points if you…

Have worked with multimodal embeddings (image, video, text, audio)
Have self-hosted ML models or worked with GPU infrastructure
Care deeply about code quality and best practices
Are curious about the creator economy

🧑‍🔧 We’re looking for people that

Are tirelessly in search of the best versions of ourselves – Who want to really show what they’ve got and want to prove the world and themselves what they’re capable of.
Are direct in their communication – We support and encourage one another through direct, immediate & helpful feedback.
Know how to become autonomous - Who we can trust to do their best work without needing processes to guardrail.
Are willing to take ownership to stand up for ourselves, our teams, and our communities.
Have fun, are honest, and do great work – No title chasers, no finger pointers, no being awful. Absolutely no slowing down to protect ego.

Benefits

🎁 What we offer

Fully remote — work from anywhere in Europe
Unlimited paid vacation 🌴
Flexible hours — async-friendly culture
High ownership, low bureaucracy, no bullshit.
Personal development support — courses, books, or conferences on us
Regular offsites — connect with your team IRL

Help us build the search backbone of the creator economy. Apply now — we’d love to meet you.😊

And a little more about us...

Founded by a high-school dropout and a Canadian (yes, we’re also shocked it’s going so well), Modash is building a suite of tools that help brands scale partnerships with online content creators.

1500+ companies like Google, Wolt (Doordash), Bolt, and Nord VPN, Stanley and others use Modash to find, analyze and monitor social media creators.

We’re a profitable company. We’re also backed by the best investors in Europe. Including Icebreaker.vc, Change Ventures, and a group of Europe’s top founders.

We’re a small team and we’re just getting started. You’ll work with people who have done everything from building solar cars to hanging out with Metallica and Bon Jovi.

Folks who have seen the inner workings of companies like Amazon, Veriff, Pipedrive, Yes, and the burning man of startups - Pirate summit. Come be great and do great things and make great stuff and create great memories while making a great impact. Do it.

Bonus: link to GitHub, portfolio, or personal site.

Benefits

Work on a revolutionary product at the intersection of travel and machine learning.
Direct impact: your models go to production and shape the core of the product, not stay in research slides.
Fast growth environment: exposure to modern ML stacks (transformers, multimodal ML, computer vision) with constant room to experiment.
Freedom & flexibility: fully remote setup, no corporate bureaucracy, focus on output not hours.
Ownership: you’ll have autonomy in decision-making and the chance to influence product direction.
Flat team structure: work directly with founders and senior engineers, no endless management layers.
Visibility: your contributions will be recognized, not lost in a big company hierarchy.

About PostHog

We're shipping every product that companies need to run their business from their first day, to the day they IPO, and beyond. The operating system for folks who build software.

We started with open-source product analytics, launched out of Y Combinator's W20 cohort. We've since shipped more than a dozen products, including:

A built-in data warehouse, so users can query product and customer data together using custom SQL insights.
A customer data platform, so they can send their data wherever they need with ease.
Max AI, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.

Next on the roadmap are CRM, messaging, revenue analytics, and support products. When we say every product that companies need to run their business, we really mean it!

We are:

Product-led. More than 100,000 companies have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.
Default alive. Revenue is growing 10% MoM on average, and we're very efficient. We raise money to push ambition and grow faster, not to keep the lights on.
Well-funded. We've raised more than $100m from some of the world's top investors. We're set up for a long, ambitious journey.

We're focused on building an awesome product for end users, hiring exceptional teammates, shipping fast, and being as weird as possible.

Things we care about

Transparency: Everyone can read about our roadmap, how we pay (or even let go of) people, our strategy, and how we work, in our public company handbook. Internally, we share revenue, notes and slides from board meetings, and fundraising plans, so everyone has the context they need to make good decisions.
Autonomy: We don’t tell anyone what to do. Everyone chooses what to work on next based on what's going to have the biggest impact on our customers, and what they find interesting and motivating to work on. Engineers lead product teams and make product decisions. Teams are flexible and easy to change when needed.
Shipping fast: Why not now? We want to build a lot of products; we can't do that shipping at a normal pace. We've built the company around small teams – autonomous, highly-efficient groups of cracked engineers who can outship much larger companies because they own their products end-to-end.
Time for building: Nothing gets shipped in a meeting. We're a natively remote company. We default to async communication – PRs > Issues > Slack. Tuesdays and Thursdays are meeting-free days, and we prioritize heads down building time over perfect coordination. This will be the most productive job you've ever had.
Ambition: We want to solve big problems. We strongly believe that aiming for the best possible upside, and sometimes missing, is better than never trying. We're optimistic about what's possible and our ability to get there.
Being weird: Weird means redesigning an already world-class website for the 5th time. It means shipping literally every product that relates to customer data. It means building an objectively unnecessary developer toy with dubious shareholder value. Doing weird stuff is a competitive advantage. And it's fun.

Who we're looking for

Enthusiastic drivers. We need proactive people that can fully own projects and get them done, and know to get help when needed. This is what being a product engineer is all about. "Are we there yet?" is the wrong question.
Optimistic problem solvers. Things get hard here sometimes – whether it's scaling, shipping complex products, handling a stream of support requests, or trying to ship something that touches multiple teams. We need people who won't get disheartened, and will collaborate, iterate, and ship their way out of anything.
Grown ups. We’re an international bunch of weirdos, but one thing unites us: everyone is kind, considerate, and professional towards each other. This isn't about age or experience, it's about being low-ego, flexible, and respectful.
Genuine builders. PostHog is full of people who just love building stuff, people who would still be building software even if there wasn't a paycheck at the end. If this sounds like you, we should talk.

What you'll be doing

Owning products and features from beginning to end. This means originating ideas based on your intuition, talking to users, and understanding our strategy and goals. It means testing MVPs in production with real users. It means iterating on their feedback, owning pricing, and ensuring the ongoing success of your work.
Collaborating with design (when necessary). Product engineers at PostHog are full stack, so we expect you to ship and own the basic UX of your work using our design system. From there, it's up to you to decide when to collaborate with our design team to iterate and polish the experience.
Implementing AI features. LLMs, eh? They're getting prettaaay, prettaay good. All our products integrate with Max AI, so you'll likely be working with the Max AI team to implement AI features in your products.
Talking to users. Good product engineers read feedback from users and iterate quickly. Great product engineers have users they're friendly with, talk with them frequently, bounce ideas off them, and iterate with them when they ship new things.
Doing support. Every week, one person in each engineering team is designated the Support hero. Their job is to investigate and resolve issues reported by customers for their product. Giving users support from real engineers, and shipping fixes and improvements in real-time, is one of the best ways to spark joy in users. This role will also include some on-call time, too.
Writing docs. We have a content team that will collaborate with you on reviewing, polishing, and improving your documentation, but the best person to document a new feature is the person who built it.

Requirements

Full-stack experience with relevant technologies – e.g. Python or similar, React or similar, something to do with big data is a bonus.
Experience taking a project from 0 to 1. You might have led a project, been a founder previously, or built an impressive side project.
Strong writing skills. We document everything, most of it publicly. The ability to communicate your ideas and make persuasive arguments is essential.

Nice to have

Have worked at a high-growth SaaS company before.
Extensive knowledge of Django and/or TypeScript-based React.
Experience building AI-native products, or integrating AI into existing software.

If you have a disability, please let us know if there's any way we can make the interview process better for you - we're happy to accommodate!

Help us build the multimodal data stack for physical AI

At Rerun, we’re building a new multimodal data stack for physical AI. Large parts of the physical-world economy will be transformed by these technologies, and we're building the data infrastructure and tools that enable it to happen. Data volumes grow big quickly with these applications and performance matters everywhere; from micro interactions to high throughput jobs.

With multimodal data stack we mean tools for extraction, ingestion, storage, querying, streaming, and visualization of temporal multimodal data. Rerun’s open source project is already loved by some of the best teams in the world, and focuses on visualizing and handling multimodal logs. You'll join a newly formed team building out Rerun's commercial offering for ingesting, indexing and querying multimodal data at scale.

What you'll work on

You will work on a cloud-native analytical database system built for multimodal (often time-series) data.

The system is built in Rust and makes extensive use of Apache Arrow. It supports specialised queries to handle robotics-style multimodal logs (very sparse and wide tables) and domain specific operators (e.g. related to 3D transforms).
- Note: prior robotics knowledge is not necessary
You will design, implement and operate the core pieces that make sure this data-intensive system is highly scalable, reliable and observable.

We'd love it if you have

Experience with async Rust in production
A deep understanding of all the systems, layers, and abstractions sitting between your code and the hardware, and willingness to move across them.
Experience building highly scalable data-intensive systems
Comfort with concepts like query planning, push-down filtering, and query optimisation
Experience deploying and operating complex systems in the Cloud (AWS/GCP/Azure)
Great communication skills in English - you'll be working in a tight-knit remote team
A helpful attitude and a curious mind with an ownership mindset - we're all doing this together!

Nice-To-Haves

Experience with Apache Arrow and Apache Datafusion
Experience with GPU workloads
Interest or experience in relevant domains like machine learning, robotics, AR/VR, or simulation

How we work at Rerun

We're a remote company headquartered in Stockholm, Sweden.
We meet up in person for a week roughly once a quarter
The team you'll join has members in European and US-east timezones
Everyone is available for synchronous work between 1:30–5:00pm CET.
Given our current team distribution, candidates outside of Europe or the US will be considered on a case-by-case basis to ensure there’s enough overlap for effective collaboration.
We've put together an uncommonly talented tech team, value agency and helpfulness highly, and expect everyone to take broad responsibility for what they build
We offer competitive cash and equity compensation, six weeks paid vacation, and whatever hardware and software you need to do your job

Most of all we hope you're excited to build some really cool technology that will have a real impact on the world with us!

If you find that you don't fit neatly into this or any of the other open roles, we're not that rigid and are generally looking for great developers who can contribute to what we're building. Just go ahead and apply to the one you think is the closest and we'll take it from there!

ABOUT POOLSIDE

In this decade, the world will create artificial intelligence that reaches human level intelligence (and beyond) by combining learning and search. There will only be a small number of companies who will achieve this. Their ability to stack advantages and pull ahead will determine who survives and wins. These companies will move faster than anyone else. They will attract the world's most capable talent. They will be on the forefront of applied research and engineering at scale. They will create powerful economic engines. They will continue to scale their training to larger & more capable models. They will be given the right to raise large amounts of capital along their journey to enable this.

poolside exists to be one of these companies - to build a world where AI will drive the majority of economically valuable work and scientific progress.

We believe that software development will be the first major capability in neural networks that reaches human-level intelligence because it's the domain where we can combine Search and Learning approaches the best.

At poolside we believe our applied research needs to culminate in products that are put in the hands of people. Today we focus on building for a developer-led increasingly AI-assisted world. We believe that current capabilities of AI lead to incredible tooling that can assist developers in their day to day work. We also believe that as we increase the capabilities of our models, we increasingly empower anyone in the world to be able to build software. We envision a future where not 100 million people can build software but 2 billion people can.
