What is a senior supplier development engineer?

A Senior Supplier Development Engineer is a professional responsible for improving and managing the performance of suppliers within a company's supply chain. They work to ensure suppliers meet quality, cost, and delivery requirements by assessing capabilities, facilitating process improvements, and supporting supplier onboarding and development. These engineers often collaborate with cross-functional teams to resolve issues, implement corrective actions, and drive continuous improvement initiatives. Their role is crucial in maintaining a reliable and high-performing supplier base to support the company's operational goals.

How does a senior supplier development engineer typically collaborate with suppliers and internal teams to improve product quality?

A Senior Supplier Development Engineer works closely with both suppliers and internal stakeholders, such as quality, engineering, and procurement teams, to drive continuous improvement initiatives. This often involves conducting supplier audits, leading corrective action plans, and facilitating training to align supplier processes with company standards. Effective communication and relationship management are key, as the role requires balancing technical expectations with collaborative problem-solving. Regular meetings, data sharing, and cross-functional projects are common practices to ensure suppliers consistently meet quality and delivery targets.

Job description

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 Reliability team at Relativity Space ensures quality is built into every stage of the Terran R design and production process, embedding reliability from the very beginning. The team works directly with design, manufacturing, test, and launch teams to stay close to the hardware, understand constraints, and proactively shape decisions. As the program moves from development into production and scaled operations, this is the time to establish the right processes, controls, and inspections without slowing progress. The team plays a key role in balancing risk, fostering a culture of ownership, and making sure speed never comes at the cost of reliability. Success means creating a quality system that scales with the Terran R program and Relativity as a whole.

About the Role:

  • Serve as the technical point of contact for rocket parts and assemblies, resolving manufacturing and quality issues to protect production schedules.
  • Lead new product introduction by selecting manufacturing methods, identifying suppliers, and developing scalable processes.
  • Conduct design for manufacturing (DFM) reviews and apply APQP principles to ensure efficient, high-quality production from early development stages. Leverage experience with Production Part Approval Process (PPAP), First Article Inspection Reports (FAIRs), and 8D problem solving.
  • Manage supplier sourcing and evaluations, issue corrective actions, and ensure compliance with AS9100, ISO 9001, and NASA quality standards.
  • Create and develop specifications to communicate quality and manufacturing requirements across the supply base.
  • Analyze defect data, lead root cause investigations (e.g., 8D, PPAP, FAIR), and implement corrective actions to improve supplier performance.

About You:

  • Bachelor's degree in engineering, quality, or related STEM field
  • You have 8+ years of experience in supplier quality or supplier development engineering, with in-depth knowledge of industry standards like AS9100, ISO 9001, and NASA quality standards and ERP/MRP system experience.
  • You have a strong technical and experiential knowledge of manufacturing processes for space-quality hardware, including forming, cutting, machining, and assembly of various metals like stainless and carbon steels.
  • You have experience with supplier quality processes such as Production Part Approval Process (PPAP), Advanced Product Quality Planning (APQP), and First Article Inspection Reports (FAIRs) with a disciplined approach to problem solving, such as 8D methodology.
  • You have experience with New Product Development and PPAP implementation.
  • You are a self-starter who can define and own a process from scratch and roll it out to a diverse team, with willingness to travel up to 50% of the work week when needed.

Nice to haves but not required:  

  • Familiarity with high-volume inspection methods and data-driven acceptance methods
  • Strong knowledge of enterprise applications (i.e., PLM, ERP, MES) and proficient in data analysis
  • Self-starter that has demonstrated the ability to define and own a process from scratch and roll out that process through adept communication to a diverse team
  • Experience with New Product Development and PPAP implementation 

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.
