At Six Robotics, we build intelligent software that gives Unmanned Aerial Vehicles (UAVs) the ability to collaborate, adapt on the fly, and execute missions that were previously impossible. From our base in Oslo, our 70+ experts in defence, software, and AI develop our flagship autonomy and swarm platform used by both government and industry. In close partnership with the Norwegian Defence Research Establishment (FFI), we move fast from concept to live deployment, often in the field alongside end users.
We work with advanced hardware and software, a modern tech stack, and missions that demand both technical mastery and operational discipline. Everyone is close to the action, from deep technical problem-solving to field operations. We move fast and value clarity, integrity, and teamwork in everything we do.
At Six Robotics, every person executes with precision, adapts to changing conditions, and strengthens the team. Getting in is hard, and you’ll be challenged every day. But if you have the skill, the discipline, and the drive to push your limits, you’ll find no better place to deliver real-world impact while collaborating and learning from the best in the field.
Six Robotics has run a monorepo since day one as a deliberate strategy to position us for robust and rapid scaling. We've built strong tooling around it and we're ahead of most companies our age on developer infrastructure. As we scale toward hundreds of engineers, we need a full-time specialist to take it to the next level.
You will join Team Factory, which builds the internal infrastructure and tooling that engineering depends on. As a Senior Build Engineer, you will be the key contributor to the architecture and direction of our build system across our heterogeneous codebase spanning C++, Rust, TypeScript, Python, OS images, GPGPU, and AI build chains. Your focus: fine-grained internal dependency tracking, aggressive caching, smart orchestration, and shorter build times. You will also design the opinionated build interfaces that let every other team integrate their code without becoming build experts themselves.
This is a hands-on role with broad architectural authority. It's also a foundational hire for the Factory team, complementing and extending our competence on developer experience.
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.
Be the in-house expert on build systems, and bring the rest of engineering along.
We are looking for a senior, hands-on Build Engineer who has scaled a monorepo before and can address the bottlenecks before they hit us.
Unfamiliar tech stacks don't slow you down. You treat the rest of engineering as your end users, and value nothing higher.
You drive complex technical work forward independently, from design through to production-quality, maintainable solutions, knowing when to involve stakeholders and when to pull in domain experts.
You bring
8+ years of software engineering experience, with at least 4 years focused on build systems, developer infrastructure, or developer productivity at scale.
Hands-on experience with at least one scalable heterogeneous build system, such as Bazel, Buck2 or Pants.
Experience scaling a monorepo to hundreds of developers, and a clear understanding of where things break.
Working knowledge of Docker, Kubernetes, and modern CI/CD.
Strong software engineering defaults and a developer-experience mindset, naturally drawn to ideas like pit of success and least astonishment.
The ability to quickly produce idiomatic solutions using unfamiliar tools.
Nice to have
Understanding of C++ build systems.
Deep understanding of GitHub Actions customization.
Experience with HiL test orchestration at scale.
Background in automotive, autonomy, robotics, defence-tech, or other industries with similarly heterogeneous codebases.
At Six Robotics, we're not just building software - we're redefining how unmanned systems operate in the real world. If you're driven by meaningful problems, technical depth, and the chance to shape something from the ground up, you'll find your place here.
Work on problems that matter
Our technology helps unlock smarter, safer, and more adaptable UAV operations in defense and industry, solving real challenges with direct, tangible impact.
Lead the shift in a hardware-dominated space
We're bringing modern AI, autonomy, and scalable software into a field that's long relied on rigid, pre-programmed systems, to change how UAVs are designed, deployed, and managed.
Build from zero, shape the future
Join early and help define the core systems, tools, and culture of a company that’s still being built - where your ideas, code, and decisions will have a lasting influence.
Work with purpose, supported by great benefits
You'll be part of a mission-driven team that values clarity, integrity, and collaboration, offering competitive pay, equity potential, strong insurance and pension plans, and ongoing learning opportunities.
