About this Role
We are looking for a Senior Control Electronics Engineer with 3+ years of experience to design and deliver real-time electronic control systems for hypersonic strike vehicles. You'll be a hands-on engineer who personally owns hardware from design through bring-up, debug, validation, and integration, not someone who manages requirements from the sidelines. This is a high-impact role on a small, elite team building flight-critical systems at one of the fastest-moving defense companies in the country. If you have 3+ years from a top-tier startup and are exceptional, we want to talk to you too.
What will you be doing?
Designing control electronics boards (motor controllers, actuator drivers, feedback/control loops) for current and future flight vehicles
Owning your hardware end-to-end, from PCB design through bring-up, integration, debug, and production
Working with microcontrollers, microprocessors, and mixed-signal circuits with a focus on processing and real-time control
Collaborating closely with GNC, avionics, and flight software teams to ensure system integration
Defining your own requirements and driving technical decisions, there are no systems engineers here, you own the full picture
