Rust Backend Software Engineer

• 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

We'd love it if you have

• Experience with async Rust in production, or language-agnostic background with a proven ability and strong motivation to learn Rust quickly.
• Experience shipping and owning complex backend systems in production, with responsibility for design, correctness, and long-term maintenance.
• 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.
• Proven ability to operate in ambiguity, with a product mindset, shaping specifications, challenging requirements, and driving toward the right solution end-to-end.
• 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.
• This role suits engineers who are energised by ambiguity and iteration, and who enjoy turning rough ideas into solid systems.
• 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!
