Principal Software Engineer, Cloud Backend

About Six Robotics

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 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 youll be challenged every day. But if you have the skill the discipline and the drive to push your limits and always be sharpening your blade youll find no better place to deliver real-world impact while collaborating and learning from the best in the field.

About The Role

Six Robotics drones produce a lot of data: flight telemetry logs and media. Today that data lands on the Ground Control Station (GCS) and goes no further. Were building the cloud platform that changes that and this role is at the centre of it. Once its in place engineers and customers alike will be able to understand what happened on a flight debug failures learn from every mission and operate with confidence. Its a meaningful step up in what we offer on top of a product that already works.

Youre responsible for getting the data into the platform: cloud services the ingestion endpoint the GCS uploads to authentication and the API behind the dashboard. Its a greenfield project and we want it to deliver value early both internally and as something we can put in front of customers. The early calls (cloud platform deployment model protocol and auth design) will be made as a team and were hiring you to bring strong justified opinions into those conversations.

Youll work closely with the team that builds the edge software running on the GCS and alongside the frontend engineer who will build the dashboard. The cloud platform sits between them.

What You Will Do

• Design and build the cloud services that ingest flight data from our GCS instances after and during flight.
  

• Decide and commit to the cloud and infrastructure platform and the deployment model taking vendor compatibility into account.
  

• Take the platform from an internal deployment to something we can roll out to customers and decide what that deployment model looks like.
  

• Design the API contract between the GCS clients the cloud backend and the dashboard frontend.
  

• Build the authentication and secure transport layer for device-to-cloud communication including identity for non-human clients.
  

• Move us from uploading after each flight toward real-time streaming
  

• Operate what you build. Were a small team so youll be in the loop on production behaviour not just shipping and walking away.

  
  

What we are looking for

Were looking for a principal engineer who has spent enough time building cloud platforms that the design decisions feel familiar but who still wants to be hands-on in the code. Youre comfortable sitting between the engineers writing software on the drones and the engineers building what customers see and you can hold a conversation in both directions.

Youre motivated by impact. You want to design something properly build it and operate it as it grows. Youre at your best when the technical bar is high and the responsibility is real and you think about how your decisions translate into something customers can actually rely on in the field. You bring strong opinions to architectural conversations but you hold them lightly enough to change your mind when someone else is right.

We believe the right candidate brings

• 8 years of engineering experience with at least 4 of them building production backend services in public or private cloud.
  

• Real experience designing and operating ingestion or device-to-cloud systems. Youve built something that took data in from clients you didnt fully control and you can talk about what was hard.
  

• You treat infrastructure as code by default with the same standards youd apply to application code: reviewed tested versioned alongside the services it supports.
  

• Strong API design judgment. You can explain why youd pick REST vs gRPC vs something else for a given problem and youve had to evolve an API in production.
  

• Architectural ownership. Youre the person on your current team who picks the cloud services commits to a deployment model and explains the choice to everyone else.
  

• Extensive experience with at least one of Go Python Rust or similar as a primary backend language. We havent locked in our stack; thats one of the early calls this role will be part of shaping but you should be deep in at least one of them and pragmatic about the choice.
  
  
  Nice-to-haves:

• Experience in IoT telemetry fleet monitoring drone or robotics platforms or any other system where the clients sit in the field and the network is sometimes hostile.
  

• Background with Rust on the backend.
  

• Experience with streaming systems where you actually had a real-time requirement to justify them.
  

• Media streaming or video pipeline experience.

Why You Should Join

At Six Robotics were not just building software; were redefining how unmanned systems operate in the real world. If youre driven by meaningful problems technical depth and the chance to shape something from the ground up youll 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

  Were bringing modern AI autonomy and scalable software into a field thats 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 thats still being built - where your ideas code and decisions will have a lasting influence.
  

• Work with purpose supported by great benefits
  Youll 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.
