Senior Avionics PCBA Development Engineer

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Avionics team is responsible for the full lifecycle of Terran Rs 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: youll get to help shape Terran Rs fundamental avionics architecture and be given a high degree of ownership on components that will fly.

About the Role:

As the Senior Avionics PCBA Development Engineer you are part of the Avionics Engineering team and responsible for the entire bring-up of new avionics prototypes. Youll program machines develop processes conduct inspections and troubleshoot defects hands-on while maintaining process control documentation. A key differentiator: youll partner with design engineers and manufacturing engineers and support DFM initiatives while realizing the first prototype builds and using tools to harvest process data. Youll also bridge to the manufacturing team supporting the handover of mature products and processes for mass production. Youre both a technical craftsman and a technology integrator combining hands-on manufacturing expertise with modern tools and automation while collaborating across engineering design and manufacturing teams. Responsibilities include:

• Provide DFM feedback: Review PCB designs for manufacturability and partner with hardware engineers to resolve assembly issues before builds begin
• Operate the full SMT line: Support the operation of every station on the line for Avionics prototype builds to ensure quality and process control.
• Inspect and troubleshoot: Perform first-article inspections (visual AOI X-ray) investigate defects such as bridging tombstoning and voiding and drive corrective actions to root cause
• Program and optimize equipment: Develop programs and tune parameters placement routines and reflow profiles for high-reliability aerospace PCBAs
• Build and rework hardware: Support prototype and qualification builds hands-on and perform professional-grade soldering and PCBA rework including component replacement BGA rework and fine-pitch repairs
• Maintain process control documentation: Work with the team to keep work instructions assembly drawings inspection criteria and process specifications current
• Develop automation tools: Build and enhance tools for machine-programming automation data-collection pipelines and analysis workflows that improve efficiency and reduce manual effort

About You:

• Bachelors degree in Electrical Mechanical or Manufacturing Engineering or a related field (or equivalent hands-on experience)
• 58 years of hands-on PCBA assembly experience in a manufacturing environment
• Proficiency with SMT equipment including solder paste printers pick-and-place and reflow ovens.
• Professional-grade soldering and rework skills including component replacement fine-pitch soldering and BGA rework
• Strong understanding of SMT processes common defects and troubleshooting including inspection methods such as visual AOI (Automated Optical Inspection) and X-ray
• Detail-oriented with the ability to read PCB assembly drawings schematics and datasheets and comfortable building automation tools or scripts to improve data collection and analysis

Nice to haves but not required:

• IPC-A-610 (CIS) or IPC-J-STD-001 soldering certification (highly preferred)
• Experience with low-to-mid-volume or prototype PCBA manufacturing and familiarity with aerospace/defense quality requirements (AS9100 IPC Class 3)
• Programming and scripting skills (Python JavaScript SQL) for tool development and data analysis including experience integrating manufacturing equipment with data systems (MES Jira APIs databases) and applying AI/ML or agentic workflows in manufacturing
• Familiarity with specialized processes and handling standardsselective soldering conformal coating potting ESD control moisture-sensitivity handling and component traceabilityas well as ECAD tools such as Altium and Valor NPI
