Relativity seeks a highly talented Senior/Lead Propulsion Development Engineer to join a rapidly growing space startup. This position will build the core of our propulsion capability via the development and operation of world-class engines, turbopumps, combustion devices, and integration to complete rocket vehicle stages. A high degree of autonomy and leadership is required.

This position is based in Los Angeles but requires travel to our Mississippi test site as needed.

RESPONSIBILITIES:

• Design, build, and test advanced rocket engines and propulsion systems.
• Support propulsion system design through all phases from preliminary design and analysis to detailed design, integration, test, and qualification.
• Develop test programs and processes, analyze data and test results, and troubleshoot propulsion hardware and performance.
• Work with manufacturing engineers to develop, evaluate, and improve manufacturing methods using knowledge of product design, materials and parts, assembly methods, and quality control standards.

REQUIRED EXPERIENCE:

• An undergraduate or graduate degree (BS/MS/PhD) in engineering with 3+ years experience developing liquid rocket engines.
• Strong understanding of launch vehicle propulsion systems and components.
• ProE/CREO experience or equivalent with an understanding and application of geometric dimensioning and tolerancing (GD&T) per ASME Y14.5-1994.
• Proficient in the physics of compressible and incompressible flow, thermodynamics, multiphase flow, mechanics, and materials.
• Good understanding and experience working with advanced manufacturing techniques to design for manufacturability and assembly.
• Able to work in a fast-paced and intense startup environment.
• Ability to complete projects with ownership of end-to-end solutions and minimal oversight.
• Proven judgment in making coupled technical and business decisions balancing both big picture and execution-oriented factors.

PREFERRED EXPERIENCE:

• Experience leading small teams in complex engineering projects.
• Experience with powder bed additive manufacturing and automation techniques.
• Familiarity with industry-standard propulsion design and analysis codes.
• Experience developing propulsion system design and analysis codes.
• Experience managing subcontractors, suppliers, and vendors.
• 5+ years experience developing liquid rocket engines.

This position must meet Export Control compliance requirements, therefore a United States Person as defined by 22 C.F.R. § 120.15 is required.
