Principal Software Engineer, Cloud Backend

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 and always be sharpening your blade, you’ll 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. We're building the cloud platform that changes that, and this role is at the centre of it. Once it's 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. It's a meaningful step up in what we offer, on top of a product that already works.

You're responsible for getting the data into the platform: cloud services, the ingestion endpoint the GCS uploads to, authentication, and the API behind the dashboard. It's 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 we're hiring you to bring strong, justified opinions into those conversations.

You'll 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. We're a small team, so you'll be in the loop on production behaviour, not just shipping and walking away.

What We Are Looking For

We're 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. You're 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.

You're motivated by impact. You want to design something properly, build it, and operate it as it grows. You're 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.
