About HyLight
We're on a mission to make the world more resilient to climate change.
We build HyLighters, autonomous hydrogen airships that fly silently over the planet's critical infrastructure, spotting methane leaks and preventing power outages and wildfires, all with zero emissions. By 2030, we want to be the global leader in aerial monitoring.
We've proven it flies. Now we're building the company to match the ambition, backed by Y Combinator and top-tier investors, with the resources to move fast and think big.
We don't care about traditional roles or titles. We just want people who are smart, proactive, and bring founder-level ownership. If you can bring a diverse point of view, push it forward: it will be highly appreciated.
Job Summary
You'll own the software architecture of the HyLighter, our next-generation autonomous airship for aerial inspection and environmental monitoring. This is a software-first embedded role: you bring real embedded experience, but your center of gravity is architecture, code quality, and the tooling that lets a team ship reliable flight software fast.
You will work on drone open-source software such as PX4 and QGroundControl (QGC), and you will define how our onboard and ground software is structured, built, tested, and deployed. A key part of the mission is to design a clean abstraction layer over our hardware so that a HyLighter can be driven as a single, coherent machine, and to put in place the CI/CD and continuous-development practices that make that architecture maintainable as we scale.
Mission
Under the guidance of the CTO, you will:
Personal Note from Josef (CTO)
"This role is the backbone of how we build software at HyLight. We have flight code, ground tools, test benches and custom machines, and we need someone who can bring real architecture to all of it and the CI/CD discipline that keeps it reliable as we grow. If you love designing clean systems, working close to the hardware through PX4, and building the pipelines that let a team move fast without breaking things, this is your spot. The team is still small (around 18 people), so your architecture decisions will have immediate, visible impact."
