Rerun

ABOUT RERUN We're building the data stack for Physical AI. The Rerun viewer is loved by the best robotics and spatial-AI teams. Rerun Hub, our data lakehouse, is in private preview and already managing petabytes of data for early customers. This is a hands-on, customer-embedded engineering role, right at the sharp end of physical AI. You'll work side by side with our customers over multi-month engagements, making sure the messy complexity of physical data never slows them down. We want builders. You'll stand up data pipelines and integrations, get customers' data flowing into Rerun, and keep their production systems moving. And by getting deep into their workflows and pain points, you'll help point Rerun's product and engineering teams at the problems that matter most. This is an early, high-ownership role. You'll help shape how deployments work as we grow. WHAT YOU'LL DO - Run technical discovery and scope solutions for customer problems - Solve hard data and infrastructure problems inside customers' production environments - Feed recurring issues, patterns, and product gaps back to Rerun's engineering and product teams - Coordinate work across Rerun and the customer to keep deployments moving BACKGROUNDS WE'RE LOOKING FOR We care about a strong technical foundation and genuine customer curiosity far more than a job title. You likely come from one of these backgrounds: - Data engineering / data platform engineering. You've built pipelines and worked with large-scale data. - Infrastructure / platform engineering. Solid systems background, plus real curiosity about the product and the customer, not just the infrastructure. - Software engineering with substantial data work. You've spent real time close to data, not just application code. WHAT WE'RE LOOKING FOR IN YOU - Strong in Python and hands-on data work - Able to learn fast and work through ambiguity - Comfortable being customer-facing: asking probing questions, surfacing hidden requirements, and coordinating across teams - Genuinely energized by understanding someone else's problem and solving it with them - ~30% travel to spend time with customers during deployments NICE TO HAVE - Robotics, autonomy, perception, or sensor-data experience - Open-source contributions or side projects you're proud of - Customer-facing experience 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.

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. Rerun's open source project focuses on visualizing and handling multimodal logs, and is already loved by some of the best teams in the world. A lot of these teams are sitting on petabytes of robot data, far more than any local tool can handle, so we also built Rerun Hub, a database purpose-built for querying and visualizing across the whole archive. We're an open core company. The viewer and SDKs are open source and stay that way, so a large part of what you build with us directly benefits the Rerun community, whether that's robotics, AR/VR, autonomous systems or more. The rest connects that open source layer to infrastructure operating at a very different scale. WHAT YOU'LL WORK ON - Build and evolve the Rerun viewer and cross-language SDKs, handling large volumes of 2D, 3D, time-series and statistical data in real time. - Integrate the viewer seamlessly with Rerun Hub, so users can work with data far larger than their machine without it feeling that way. - Make technology and architecture decisions that reach across the full stack, and keep the system maintainable as the volume of data flowing through it grows. - Work closely with the Hub, backend and design teams. A lot of the interesting problems live between those boundaries, so reaching a good compromise quickly matters. - Profile and optimize user workflows across desktop platforms and the web. - Contribute to downstream open source projects when that's what it takes to make progress. - Work directly with the people using Rerun, from the open source community to our customers running it on very large datasets, and help them get great results WE WOULD LOVE IF YOU HAVE - Strong programming skills in Rust or another compiled language You'll need to be fluent enough to read and work in our Rust codebase, but you don't need years of production Rust behind you. - A generalist with UI skills. You'll move between the interface, rendering, data handling and infrastructure rather than staying in one lane, so we need people who can build interfaces that feel good to use. - Experience with interactive data visualization, particularly large datasets and complex visual structures. - Experience building real-time, high-performance applications. - Comfort with ambiguity. We're small and move fast, so we need people who find the problem, make a call, and tell everyone, rather than waiting to be told what to do. - Great communication skills in English. You'll be working with the community as well as your team. NICE-TO-HAVES - Experience contributing to or maintaining open source projects, especially ones with a real community around them. - A background in something close to what we do: robotics (RViz is a big plus), simulation, streaming, rendering, or game engines. - Knowledge of GPU rendering pipelines like wgpu, and how to get performance out of them. 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 and 5:00pm CET. Given our current team distribution, candidates outside Europe or the US will be considered case by case, to make sure 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.

Rerun is building the data layer for physical AI. Robots, drones, and self-driving cars all run on physical data: multimodal, multi-rate sensor streams tied to time, space, and embodiment. Data infrastructure built for web and business data breaks down under that load. Rerun's open source SDK has become a default way robotics teams visualize, log, and query this kind of data. On top of that open source foundation, Rerun is now building Rerun Hub, a commercial data catalog and storage engine, currently in private preview, that extends the same tools to the scale of object storage. The strategy mirrors the open source to commercial platform playbook of Confluent, MongoDB, and Elastic, except Rerun is building the category as well as the company. Some of the most ambitious teams building physical AI already build on Rerun's open source tools, including teams at Meta, Google, Hugging Face, and Unitree. THE ROLE Physical AI is being built by a community of robotics engineers, ML researchers, and builders scattered across a handful of hubs and a lot of Discord servers and meetups. That community doesn't have a heartbeat yet, and that's this role. You'll bring creative thinking to where and how this community shows up: which cities and labs are actually building physical AI, what kind of events and programs get them in a room together, and how to give this community real content and social touch points, not just another meetup series. It's part field marketing, part developer evangelism, built for someone who wants to design and run that program rather than inherit one. WHAT YOU'LL WORK ON - Map the physical AI landscape: the cities, labs, companies, and communities where the people building this space actually are. - Design and run developer events, physical and virtual, from small meet ups and hack nights to a presence at larger industry conferences. - Build recurring programs that give the community real content and social touch points, not one-off events that go nowhere. - Partner with engineering and the founding team on the technical content that makes these events worth showing up to. - Represent Rerun in the robotics and physical AI community, at conferences, meet ups, and with key open source contributors. - Coordinate closely with the founding team in Sweden to start, then partner with Rerun's VP of Marketing in SF once that role is filled. WE'D LOVE IT IF YOU HAVE - 3-7 years in field or community marketing, with real depth in event planning, physical and virtual. - Experience marketing to or building community for a technical audience at a B2B tech startup. - You've personally organised meet ups, hackathons, workshops, dinners, or conferences; not just supported someone else running them. - You've built something recurring, a series or a programme, rather than only one-off events. - Experience working closely with founders or engineering teams, and ideally with developer or open source communities. - Real hospitality instincts and taste. You notice when an event is curated and when it isn't. - Comfortable travelling up to 40% of the time. - Genuine curiosity about robotics and physical AI. HOW WE WORK AT RERUN - This role is based in the Bay Area, hybrid, with 3 days a week in our SF office. - 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.
