Job summary

Six Robotics in Oslo is seeking a Senior Build Engineer to lead the evolution of our internal build system across a heterogeneous codebase (C++, Rust, TypeScript, Python). You will own architecture, tooling, and optimization of the monorepo, enabling faster builds and better developer experience across teams.

You will join Team Factory as a senior contributor with architectural authority, shaping how engineers integrate and deploy code while maintaining high reliability and scalability.

Qualifications

Responsibilities

• Run the technical review to pick a new build stack (Bazel, Buck2, Pants, or similar), and integrate it with existing monorepo tooling.
• Design high-level, opinionated build interfaces that give feature teams a consistent and expressive way to integrate their code, without requiring them to become build experts.
• Improve caching, orchestration, and remote execution in our existing self-hosted CI and HiL testing infrastructure.
• Set the engineering defaults that every team inherits, with an eye toward correctness, reproducibility, and developer experience.
• Spot the next high-leverage improvements and bring concrete proposals; What to do, what it achieves, why now, what it takes.
