Embedded Software Developer Jobs in Seattle, WA (NOW HIRING)

The Director of Embedded Software Engineering will lead mission-critical embedded software development for Amazon Leo's satellite bus systems, ensuring our satellite constellation meets aggressive reliability, security, and performance targets from manufacturing through end-of-life operations.
This role owns all embedded software development and systems testing for satellite spacecraft systems - including flight software, real-time operating systems, avionics, and on-orbit software validation. You will architect the software that sits on the satellite, manage the end-to-end software stack to bring up the satellite, and lead comprehensive system testing to ensure spacecraft readiness for launch and on-orbit operations.
This is a highly technical leadership role requiring hands-on embedded software architecture expertise combined with the ability to build and scale high-performing engineering organizations. You will work in constrained hardware environments where computing resources (processing power, memory, power consumption) are severely limited

A satellite has 600+ unique processors - it's like having its own compact data center in space - requiring sophisticated embedded software solutions to coordinate this complexity.
Key job responsibilities
As a group leader, you will anticipate bottlenecks, provide escalation management, anticipate and make tradeoffs, and balance the business needs versus technical constraints. The ability to take large, complex projects and break them down into manageable pieces, develop functional specifications, then deliver them in a successful and timely manner is expected. Maturity, judgment, negotiation skills, ability to influence, analytical talent and leadership are essential to success in this role.
