Principal Software Engineer - Simulator

Engineering · Oslo

Join us to build the simulator that shapes the future of UAV autonomy.

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. We only hire the best. 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.

About the role

We are looking for an experienced Principal Software Engineer to lead the design and development of our simulation platform. This role is critical to our ability to develop, test, and validate our autonomy algorithms before deployment. You will drive the technical direction of the simulator, establish best practices, and mentor a small team.

Your responsibilities will include:

• Architecting and leading the development of our simulation platform

• Designing high-fidelity models of UAV dynamics, sensors, and environments

• Optimizing simulator performance for rapid iteration and testing

• Establishing coding standards and best practices for the simulator team

• Mentoring engineers working on simulation

• Collaborating with the autonomy team to ensure the simulator accurately represents real-world conditions

About you

We are looking for someone with:

• 8+ years of software engineering experience, with 3+ years in a technical leadership role

• Strong experience with simulation software or physics engines

• Expertise in C++

• Deep understanding of software architecture and design patterns

• Experience with 3D graphics or visualization (a plus)

• Proven ability to mentor and lead engineers

• Strong problem-solving and communication skills

Nice to haves:

• Experience with robotics simulation (e.g. Gazebo, Webots, CoppeliaSim)

• Familiarity with game engines (Unreal, Unity) or 3D graphics libraries

• Understanding of aerodynamics or physics simulation

• Experience with real-time systems

Why Six Robotics

• A talented, collaborative team with an ownership mentality

• Cutting-edge autonomy and swarm technology

• Daily interaction with defence operators and real-world impact

• Competitive compensation with an option programme for early employees

• Modern tech stack and tools

• 10K annual gear budget

• Health, travel and life insurance

• Beautiful Oslo office with lab access

We are committed to creating an environment where talent thrives. We believe great engineering happens when thinking and action are given space and trust, and every person can make a clear difference in what we do.

If this sounds like an opportunity for you, we would love to hear from you!
