About this job

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, 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. You've built something that took data in from clients you didn't fully control, and you can talk about what was hard. You treat infrastructure as code by default, with the same standards you'd apply to application code: reviewed, tested, versioned alongside the services it supports. Strong API design judgment. You can explain why you'd pick REST vs gRPC vs something else for a given problem, and you've had to evolve an API in production. Architectural ownership. You're 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 primar
