Technical Lead – Data Platform & Storage

At Rerun, we're building the missing data stack for Physical AI. Our open-source project is already used by some of the best teams in the world, and we're now building the commercial data platform on top of it a high-performance analytical system written in Rust, built on Apache Arrow.

We're looking for a hands-on Tech Lead who is equally an architect and a builder. You'll own the technical direction of the platform mapping out storage architectures, making the hard calls on abstractions and then go implement them. Our engineers will look to you for direction on storage, query execution, and data infrastructure. This is not a role where you write documents and attend meetings; you'll be in the codebase, shaping architecture through design and implementation, while raising the bar for the team around you.

What you'll do

• Set technical direction across the data platform and be a credible voice across the wider engineering org

• Design, implement, and operationalize core systems hands-on: writing code, reviewing PRs, debugging production issues, making architectural calls

• Write POCs to validate ideas and give the team something concrete to move toward

• Define the boundaries between the data platform, SDK, and lower layers of the stack

• Represent Rerun's approach to data infrastructure externally at conferences, in the community, with customers

We'd love it if you have

• Deep, hands-on experience building, optimizing, and operating storage and/or database systems in production

• Polyglot background: you're senior enough to have worked across languages and paradigms, and comfortable picking up new ones; we're a Rust shop and you'll need to get fluent

• Familiarity with columnar formats (Arrow, Parquet), query engines, or storage engine design

• The kind of technical credibility that makes people trust your opinion and look to you for direction

• Technical evangelism: representing Rerun's novel approaches to data infrastructure at conferences, in the community, and with customers. You'll be a visible, credible voice for what we're building and why it matters

• Partnering with product to ensure the platform evolves around real customer needs, not theoretical ones

This role tends to resonate with engineers who

• Want to shape a data platform while it's still being defined, not maintain one that's already built

• Are as comfortable debugging a production issue as they are designing a new storage architecture

• Enjoy creating clarity for a team while things are still evolving, not by adding process, but by making the right technical calls and explaining them well

• Care about how customers actually experience the system, not just how it looks on a design doc

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
