Senior Mixed-Signal Hardware Engineer

About the Team:

The Avionics team is responsible for the full lifecycle of Terran R's nervous system, designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground. The team leverages close partnership between avionics design, manufacturing, and test to enable rapid iteration and feedback loops. Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: you'll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly.

About the Role:

As a Mixed-Signal Hardware Engineer on the Avionics team, you will design, test, and analyze custom electronics on the Terran R launch vehicle. You will oversee hardware development through the entire product lifecycle from concept to flight maturity to include initial design, board bring-up, design verification, qualification, initial flight production, integration, and vehicle operations. You will work with cross-functional partner teams across the company to help the team make the best possible decisions for the overall vehicle. A strong candidate for the role will have a deep technical background in electronics design and sound project management skills to ensure the hardware project is both reliable and on-schedule to support Terran R's launch!

About You:

• Bachelors degree in Electrical Engineering, Computer Engineering, or a related field
• 5+ years of experience in electronics designed for harsh environments and mission-critical applications such as launch vehicles, spacecraft, aircraft, or robotics
• Technical expertise in ADCs, DACs, signal conditioning, amplifier circuits, filter design, etc.
• Experience with eCAD software such as Altium or equivalent
• Experience with hardware bring-up, validation, debugging, and data analysis
• Experience with board-level design from concept to manufacturing
• Experience working with highly cross-functional teams (mechanical, thermal, electrical, software, etc.) to develop integrated electronics solutions

Nice to haves but not required:

• Familiarity with embedded software development and integration for avionics systems
• Experience with design for reliability and manufacturability of avionics hardware and systems
• Understanding of interfacing hardware such as: sensors (thermocouples, pressure transducers) and electromechanical devices (solenoids, pyrotechnics, actuators)
