Relativity Space
Principal Materials & Processes Engineer, Avionics
Relativity Space, Long Beach, California, us, 90899
At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level.
About the Team: The Materials and NDE (Non‑Destructive Evaluation) team plays a central role in enabling Terran R to fly, re‑fly, and scale: developing, characterizing, and inspecting materials and processes across all parts of the vehicle. From welding and additive manufacturing to advanced composites, the team works at the intersection of innovation and execution, balancing performance and reliability with cost, quality, and schedule. As we move toward first flight and beyond, the challenges become more exciting, offering opportunities to shape how we design and develop for re‑use. With ownership across products, systems, and disciplines, engineers gain broad exposure and drive key decisions across design, manufacturing, and operations.
About the Role:
Serve as the first and primary cognizant M&P engineer for our Terran‑R‑avionics electrical and mechanical hardware
Qualify avionics materials and processes for flight and reuse
Develop, implement, and maintain technical specifications and engineering standards
Drive statistically‑driven experimental design and process improvement campaigns
Interface with:
Materials engineers to identify, define, and fill critical technology gaps
Laboratory staff to characterize materials and processes
Avionics responsible engineers to support materials selection, design and analysis, qualification, flight, and reuse
Process and manufacturing engineers to develop processes, troubleshoot issues, and enable cost & rate while maintaining performance
Quality assurance and supply chain to ensure subcontractor compliance and reliability
Leadership to develop technical roadmaps, elevate risks, and overcome roadblocks
About You:
Bachelor’s degree in materials science or engineering, or related field
9+ years of relevant avionics materials and processes experience (note: leveling is flexible and based on each candidate’s background)
A core commitment to accountability, collaboration, and execution
A desire to establish and foster strong interdisciplinary relationships across the company
An authentic, introspective, and inclusive mindset towards technical, interpersonal, and team growth and development
Nice to haves but not required:
Deep experience with aerospace avionics products and their associated materials and processes (power systems, batteries, controllers, transceivers, antennas, sensors, and harnesses)
Expertise in printed circuit board assembly processes (solder paste, printing, vapor phase reflow, underfill, staking, board wash, and conformal coat)
Knowledge of relevant industry standards (NASA, J‑STD, IPC, SMC, TOR, etc.)
Experience with statistical experimental design and data analysis
Compensation and Benefits: 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. Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.
Hiring Range: $196,000 — $253,000 USD
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
