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.

What you'll do

• 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 specialized 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

• 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, with a growing hub in San Francisco.

• We meet up in person for a week roughly once a quarter.

• We're spread across European and US time zones. Rather than one fixed window, each team keeps a few hours of daily overlap that fits where its members are, and every role posting says what that looks like.

• 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.

• Parental leave: 12 weeks full pay for every parent, alongside your local statutory leave entitlements.

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!
