Job description

At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

Team:

The Avionics team is responsible for the design, testing, and production of electronics on the Terran 1 and Terran R launch vehicles. As a member of this team, you will be responsible for avionics hardware designs that work with multiple vehicle systems including but not limited to vehicle sensors, propulsion, computing, actuation, energy management, and communications. Avionics operation is critical to the successful flight of Terran 1, the world’s first 3D printed rocket.

What you’ll do:

• Drive architecture, design, and development of mixed signal electronics that will support the launch vehicle needs
• Drive electronics hardware through the full product lifecycle including circuit design and analysis, schematic capture, layout, prototyping, bring-up, troubleshooting, issue tracking, design verification, acceptance and qualification testing, and handoff to vehicle integration
• Work with partner teams such as propulsion, GNC, mechanisms, launch, etc. to define system requirements, interfaces, and understand system performance impacts of avionics designs
• Make complex technical decisions (risk tradeoffs, evaluation of trade studies, anomaly investigations, etc.)
• Support product life cycle from design to manufacturing

What you need to know:

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field
• 1+ years of experience in mixed-signal circuit design such as amplifiers, filters, analog to digital and digital to analog converters, I2C, Ethernet, SPI, and processors
• Familiarity 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
• Ability to communicate deeply technical topics to a wide variety of audiences
• Experience working with highly cross-functional teams (mechanical, thermal, electrical, software, etc.) to develop integrated electronics solutions
• Comfortable with working in a fast-paced and autonomously driven startup atmosphere

Nice to haves but not required:

• Knowledge in power supply components, memory interfaces, FPGAs, ASICs
• Low-noise analog signal conditioning and sensor interface design
• Experience with simulation software such as LTspice, MATLAB, or other
• Experience with design of electronics for harsh environments (vibe, thermal, vacuum, radiation, etc.)
• Experience with design of electronics for mission-critical applications (aviation, automotive, robotics, spacecraft, medical)
• Experience with system architecture development for complex electronics systems
• Full life cycle development of new hardware systems

Relativity Space offers competitive salary and equity, a generous vacation policy, an annual L&D stipend and more!
