About the role

We're focused on an ambitious goal to make generalized robots broadly accessible, enabling households to take back quality time.
If you are ready to apply your skills to the forefront of robotics innovation, we'd love to hear from you.

Responsibilities

Build system: Own and evolve our build system to keep builds fast, hermetic, and reliable as the codebase and team grow
CI/CD: Design and operate pre-merge and post-merge pipelines that catch regressions early and produce trustworthy release artifacts
Artifact pipeline: Build the packaging, versioning, and signing pipeline for the binaries that ship to the robot i.e. system software, application code, and exported/compiled ML models
Dev containers & dependency management: Define and maintain consistent development containers and package/dependency management across the team, keeping the dev environment in parity with the base Linux image that runs on the robot
Over-the-air updates: Build and operate the OTA system that delivers new software to robots safely - staged rollouts, canarying, rollback, and verification
5+ years of software engineering experience, with significant time spent on build infrastructure, developer tooling, CI/CD, or software delivery
Working knowledge of containers (Docker/OCI) and the practical tradeoffs around image building, layering, and runtime
a fast and reliable build, a CI/CD pipeline they trust, signed and reproducible artifacts and an OTA path that gets those artifacts safely onto the fleet.
You'll work alongside teammates who own the runtime substrate and the GPU and accelerated compute layer, they build what runs on the robot; you build how it gets there.
Own and evolve our build system to keep builds fast, hermetic, and reliable as the codebase and team grow

Requirements

Hands-on experience with a modern build system (Bazel, Buck, CMake at scale, or similar) in a large multi-language codebase
Experience deploying software to production environments - whether cloud, embedded devices, fleets, or similar - with a real understanding of versioning, rollback, and safe rollout
Comfort working in a systems language (C++, Rust, or Go) and a scripting language (Python) - you'll read and write both

Nice to have

Direct experience with Bazel in a polyglot codebase (C++, Python, ML model toolchains)
Experience packaging and deploying ML models - model registries, versioning, compiled/exported artifact pipelines
Background working alongside runtime, robotics or ML teams
Even if you don't meet every single requirement, we encourage you to apply.
Studies show that women and underrepresented groups often hold back unless they meet 100% of the criteria - we don't want that to be the reason we miss out on great talent.

Skills

What to Expect
From the moment a developer hits commit to the moment the new binary, middleware, or model is running on a robot in someone's home.
