Why Join Powerus

\n

\n

Every Powerus aircraft carries a set of microcontroller-based boards: flight controller, electronic speed controllers, battery management, power distribution, and payload interfaces. Each board runs software that must start reliably, report its state, and keep working through vibration, temperature extremes, and electrical noise.

\n

\n

This role writes and maintains that software across the board set, from bring-up of new hardware revisions through production release, working directly with the hardware engineers who design the boards and the manufacturing team that builds them.
