About Us STARK is a new kind of defence technology company revolutionising the way autonomous systems are deployed across multiple domains. We design, develop and manufacture high performance unmanned systems that are software-defined, mass-scalable, and cost effective. This provides our operators with a decisive edge in highly contested environments. We’re focused on delivering deployable, high-performance systems—not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe—today. Your mission As an Autopilot Engineer you will develop, adjust, and maintain flight controller firmware and autopilot systems that enable stable, reliable, and high-performance control of unmanned platforms under real-world operational constraints.
