Lead Hardware Engineer (Controllers)

Long Beach, California, United States

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

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 the Lead Avionics Controllers Hardware Engineer, you will lead a small, nimble team of electrical engineers designing custom avionics controllers that interface with critical systems across the Terran R launch vehicle. Your team's controllers will command and control rocket engines, manage fluid and tank pressurization systems, interface with customer payloads, and operate separation mechanisms. You will guide your team through the full product lifecycle including initial design, board bring-up, design verification, qualification, initial flight production, integration, and vehicle operations. You will work closely with cross-functional partner teams across propulsion, fluids, stage engineering, and GNC to ensure your controllers meet the demanding requirements of the overall vehicle. A strong candidate for this role will combine deep technical expertise in mixed-signal and analog circuit design with proven ability to mentor engineers, lead root cause investigations, and foster a culture of collaboration and high performance in a fast-paced environment.

About You

Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field
5+ years of experience in electronics design for harsh environments and mission-critical applications (including, but not limited to, launch vehicles, spacecraft, aircraft, or robotics)
Strong technical background in mixed-signal and analog circuit design, including sensor signal conditioning, instrumentation amplifiers, ADCs, DACs, and filter design
Experience designing control electronics for actuating loads such as solenoid valves, brushless DC motors, pyrotechnic firing circuits, and similar high-reliability mechanisms
Experience with sensor interfacing across diverse types including pressure transducers, thermocouples, RTDs, strain gauges, flow meters, and position sensors
Demonstrated experience leading root cause investigations using RCCA (Root Cause Corrective Action) processes and methodologies such as 5 Whys, fishbone diagrams, and fault tree analysis
Experience mentoring and leading small teams of engineers in technical and non-technical best practices
Experience driving rigorous engineering processes and initiatives (requirements capture, design reviews, design verification, FMEA, etc.)
Experience working with highly cross-functional teams (mechanical, thermal, electrical, software, fluids, propulsion) to develop integrated controller solutions

Nice To Haves But Not Required

Familiarity with embedded software development and integration for real-time control systems
Experience with design for reliability and manufacturability of avionics hardware including DFMEA, accelerated life testing, and qualification testing
Technical expertise in power electronics including motor drives and control, high-current switching circuits, DC-DC converters, and protection circuitry
Experience with communication protocols and interfaces (CAN, RS-422/485, SPI, I2C, Ethernet) for distributed control systems
Hands-on experience with environmental testing (vibration, shock, thermal cycling, EMC) and test fixture design
Knowledge of safety-critical design practices and standards (e.g., DO-254, MIL-STD-1553, IPC-A-610)

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.

Voluntary Self-Identification of Disability

Form CC-305

Page 1 of 1

OMB Control Number 1250-0005

Expires 07/31/2029

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
