Software Engineer (Rust) - Backend

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. We'd love it if you have 3-5 years experience async Rust, or a solid background in another systems language such as C or C++ and a strong motivation to pick up Rust Experience working on backend systems in production, with an interest in growing your ownership of design and architecture Curiosity about the layers between your code and the hardware; you don't need to know them all, but you enjoy digging in Exposure to data-intensive systems or an eagerness to learn what makes them tick Familiarity with concepts like filtering, indexing, or query execution; even at a high level Good communication skills in English: you'll be working in a close-knit remote team A helpful attitude and a curious mind: we're all figuring this out together! Nice-To-Haves Any experience with cloud deployment (AWS/GCP/Azure), even in a supporting role Exposure to Apache Arrow or Apache Datafusion Interest in machine learning, robotics, AR/VR, or simulation Experience with GPU workloads 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!
