Job Summary
You’ll be part of the development of the
HyLighter
, our next-generation airship designed for aerial inspections and environmental monitoring.
This position sits at the intersection of
electronics, embedded programming, and hardware integration
.
You will work on drone open-source software such as
PX4
and
QGroundControl (QGC)
, contributing to both the flight systems onboard the HyLighter and the ground station that supports operations.
You’ll help shape the development strategy for our embedded systems in the air and on the ground and take part in enhancing our testing and operational infrastructure. That includes setting up and programming microcontroller-based systems for bench tests, operational trailers, and custom manufacturing machines.
Responsibilities:
Under the guidance of the CTO, you will:
- Develop and integrate new embedded systems into the HyLighter platform
- Enhance the robustness and reliability of existing avionics and electronic systems
- Participate in system architecture design and technical studies for future features
- Work at the crossroads of software and hardware development
- Multiple payload implementation and data capture automation
- Learn from and contribute to the engineering decisions behind our new developments: steerable drones, advanced testing facilities, and new onboard systems
Personal Note from Josef (CTO)
This is a truly cross-functional position that touches everything related to hardware development.
It will have a strong impact on HyLight’s evolution and reliability.
We’re looking for someone ready to take ownership early, drive improvements, and help push the HyLighter toward new performance milestones. If you love spending your days programming microcontrollers, improving electronics, designing PCBs, and exploring diverse technical challenges this is your spot.
The team is still small (
25 people
), which means your contribution will matter immediately and visibly.
