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 - 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. - 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! ## About Rerun ## Company Overview - **One-liner**: Rerun builds the unified data layer for Physical AI, providing an open-source SDK, time-series database, and visualizer for multi-rate, multimodal data used in robotics, spatial computing, and simulation. - **Entity Type**: Private (Seed stage) - **Headquarters**: Stockholm, Sweden - **Founded**: 2022 - **Founders**: Nikolaus West (CEO), Emil Ernerfeldt (CTO), Moritz Schiebold (COO) ## Core Business - **Primary Industry**: Software Development / Data Infrastructure for Physical AI (robotics, autonomous vehicles, drones, spatial computing) - **Target Customers**: B2B — engineering teams at companies building Physical AI (robotics, autonomous systems, simulation) and researchers in embodied AI - **Mission/Purpose**: To build the multimodal data stack for embodied AI, enabling teams to ingest, visualize, query, transform, and train on multi-rate, multimodal data from teleop, fleet logs, human-data rigs, and simulation — all from a single columnar store. ## Products & Services - **Rerun SDK (Open Source)**: A logging SDK (Python, Rust, C++) for multi-rate, multimodal data. Logs are stored as column-chunks in `.rrd` files, purpose-built for physical data. Enables real-time visualization and debugging. - **Rerun Viewer**: A cross-platform visualizer for exploring, annotating, and debugging temporal and multimodal data. Supports custom views and plugins for every stage of the pipeline. - **Rerun Hub (Commercial)**: A managed data catalog and storage engine. Provides byte-range indexing, SQL/dataframe querying across recordings, column-aware and video-codec-aware dataloading for training, and transform capabilities (add derived columns, evolve schemas without history-breaking). Turns object stores into a queryable, streamable foundation. - **Rerun Query Engine**: Full dataframe or SQL queries over any robotics data, including post-processing and annotation capabilities. ## Market Standing - **Valuation**: Not publicly disclosed - **Total Funding**: $20.4M - Pre-Seed (June 2022): $3.4M from 17 investors - Seed (March 2025): $17M led by Point Nine, with participation from 9 other investors - **Key Metric**: $20.4M total funding - **Notable Investors/Partners**: Point Nine (lead investor in Seed round), Costanoa Ventures, and 17+ other angel and institutional investors from the Pre-Seed round. - **Growth Signals**: - 52% employee headcount growth year-over-year (31 employees as of mid-2025, up from ~5 in 2022) - 20,020 LinkedIn followers (+39.4% yearly growth) - Operating in 14 countries across Europe and North America - Open source project with active community contributions; stewards of open source tools the industry relies on - Commercial product (Rerun Hub) launched in 2025, now in active use by teams building Physical AI ## Competitive Advantages - **Unified Data Layer**: Combines logging, visualization, querying, transformation, and training into one columnar store — eliminating the need for export jobs, stale copies, or multiple disparate tools. - **Purpose-Built for Physical AI**: Designed from the ground up for multi-rate, multimodal data (e.g., camera feeds, LiDAR, IMU, control signals) — not a bolt-on for a general-purpose database. - **Open Source Core**: The SDK and Viewer are open source (MIT/Apache), fostering community adoption, trust, and contributions from the robotics and AI research communities. - **SQL/Dataframe Querying on Recordings**: Allows users to run complex queries across the entire catalog, down to individual time ranges and values inside recordings — a unique capability for physical data. - **Column-Chunk Storage**: Efficient for multi-rate data, enabling fast retrieval and streaming without full-file downloads. ## Strategic Focus - **Scaling Rerun Hub**: Commercializing the managed data catalog and storage engine to serve enterprise Physical AI teams. - **Building the Data Loop**: Enabling seamless data flow from teleop/fleet logs through visualization, curation, and directly into training loops — "train without an export step." - **Open Source Community Growth**: Continuing to invest in the open source ecosystem, contributing to and maintaining tools the robotics community depends on. - **Talent Acquisition**: Actively hiring across engineering (Rust backend, infrastructure, dataframe SDK), forward-deployed engineering, and strategic operations to support product and customer growth. ## Why Work Here - **Mission-Driven Impact**: Build the foundational data infrastructure that will power the next generation of Physical AI — robots, drones, autonomous vehicles, and spatial computing. - **Remote-First & Distributed**: Remote-first company with founders based in Stockholm, Sweden, and teammates across Europe, the US East and West Coasts, and Canada.
