Senior Software Engineer, Radio & Network Systems

Senior Software Ingeniør; Oslo; Sur place; NOK 900 000 - 1 200 000; Plein temps

Résumé du poste

Six Robotics, based in Oslo, seeks a Senior Software Engineer to advance the swarm communications stack. You will design and implement message flows between nodes and the ground, ensuring robust operation under challenging conditions.

The role focuses on C++ code near the Linux networking stack on embedded targets and requires hands-on experience with mesh or mesh-like protocols. Ideal candidates have 5+ years building distributed systems with lossy links and mobility, strong English, and a

Qualifications

• Shipped real systems over real radio links and evaluated trade-offs between mesh and message-flow approaches.
• Can explain why a chosen architecture was preferred in production environments.
• Demonstrates strong engineering defaults and clear technical communication.

Responsabilités

• Drive the architecture call on how messages flow across the swarm and ground.
• Build robust node-to-node and swarm-to-ground communication.
• Consider QoS, prioritisation, and fallback behavior across links under packet loss and mobility.
• Write the C++ that integrates with the Linux networking stack on embedded systems.
• Spend time in field testing and contribute to on-site debugging efforts.
• Influence platform and radio decisions impacting the comms architecture.

Description du poste

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.

About The Role

Our drones operate as a swarm. They need to talk to each other, and to the ground, in conditions that don't forgive sloppy communications: packet loss, moving nodes, limited bandwidth, and a mix of wireless devices. This role deals with how the network is actually used by applications.

You’ll work on how data actually moves between nodes in the swarm and between the swarm and ground. The mission is to take communication from working in the lab to working in the field, every time, under contested conditions. That’s an architecture problem, a code problem, and a debugging problem in equal measure, and you’ll be a key contributor on all three alongside the rest of the team.

You’ll work closely with engineers across teams, particularly those integrating new hardware like radios and those running simulation efforts.

What You Will Do

• Drive the architecture call on how messages flow across, whether that’s through existing mesh routing protocols or a custom propagation approach

• Build robust node-to-node and swarm-to-ground communication

• Consider QoS, prioritisation, and fallback behaviour across multiple links, especially under packet loss and mobility

• Write the C++ that makes it work, close to the Linux networking stack on embedded systems

• Expect a bit of time in the field. Conditions outside the lab surface things a desk never will, and you’ll be part of working through them

• Be a strong voice on platform and radio decisions where the comms architecture is affected, even though new radio integrations are not your day-to-day

What We Are Looking For

We believe you've shipped real systems over real radio links before, and you know what holds up versus what looks fine in a demo. You might have made the call between mesh and message-flow approaches, or something equivalent, and you can explain why you went the way you did.

We believe the right candidate brings:

• 5+ years as a software engineer, with 3+ of those building communication or distributed-systems software in production, where lossy links and mobility were real constraints

• Strong engineering defaults, comfortable C++ and on embedded Linux

• Hands-on experience with mesh or message-flow protocols

• Familiarity with IP radios and how application logic sits on top of them

• Strong communication skills. You can explain technical trade-offs clearly to people who don’t share your domain expertise

• Fluent in English (Norwegian not required)

• A Master’s degree or equivalent practical experience in a relevant field

Nice to have:

• ROS 2 / DDS with real QoS tuning experience

• MAVLink

• 4G/5G modems on embedded targets

• Background from defence tech, robotics, telco/MANET, or military signals environments

Why You Should Join

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.

Our Commitment to Inclusion

At Six Robotics, we are committed to creating a workplace built on respect, integrity, and collaboration. We value different perspectives and experiences, and we believe that diversity within our team strengthens both our work and our culture. We encourage all qualified candidates to apply and help us build technology that makes a real impact.

Security Clearance Requirement

All employees at Six Robotics are required to undergo a security clearance due to our close collaboration with the Norwegian Armed Forces. While prior clearance is not necessary, the clearance process will be initiated as part of onboarding.
