Senior Propulsion Engineer

Divergent is seeking an experienced Senior Propulsion Engineer to support the development of next-generation propulsion systems, with an initial focus on turbojet engine development. We are transforming traditional engine design and manufacturing by leveraging advanced materials, additive manufacturing, and functional integration through our Divergent Adaptive Production System (DAPS).  

This is an opportunity to join a greenfield, first-of-its-kind propulsion development program and play a critical role in bringing innovative engine architectures from concept to hardware. The ideal candidate brings deep technical expertise in propulsion or turbomachinery, a strong foundation in multidisciplinary engineering, and a hands-on approach to solving complex challenges through rapid prototyping, testing, and iteration.  

Depending on experience and demonstrated technical experience, this position may be hired at the Engineer, Senior Engineer, or Staff Engineer level.  

• Drive the design, development, and integration of next-generation propulsion systems, with an emphasis on turbojet engines and turbomachinery.  
• Own key propulsion subsystems and components from initial concept and requirements development through detailed design, hardware build, integration, and testing.  
• Apply engineering fundamentals across thermodynamics, fluid dynamics, heat transfer, structural mechanics, and materials science to solve complex propulsion challenges.  
• Develop and optimize critical engine components, including compressors, turbines, combustion systems, rotating assemblies, valves, and instrumentation.  
• Partner with cross-functional engineering teams across design, analysis, manufacturing, and testing to develop integrated propulsion solutions.  
• Leverage Divergent's DAPS technology stack to incorporate additive manufacturing, advanced materials, and functional integration into propulsion system architectures.  
• Drive rapid hardware development through prototyping, design iteration, testing, and model correlation.  
• Evaluate component and system performance, identify design limitations, and implement improvements to meet performance, reliability, and durability requirements.  
• Support engine testing, instrumentation, data analysis, and troubleshooting to validate designs and drive development forward.  
• Manage engineering trade-offs across performance, weight, size, cost, manufacturability, and schedule while maintaining system-level requirements and safety objectives.  
• Collaborate with manufacturing and DAPS technology teams to improve design for manufacturability and advance additive manufacturing processes and capabilities.  
• Provide technical guidance and mentorship to other engineers while helping establish engineering best practices and development processes.

• Ability to lawfully access information and technology that is subject to US export controls 
• BS in Mechanical Engineering, Aerospace Engineering, or equivalent.  
• 4+ years of experience in propulsion, gas turbine, turbomachinery or engine development.  
• Strong technical understanding of turbojet engines, turbomachinery, and propulsion system architectures.  
• Experience with the design, development, and integration of mechanical components and complex engineered systems.  
• Solid understanding of multiphysics behaviors across turbomachinery, combustion devices, valves, instrumentation, and associated components.  
• Strong foundation in thermodynamics, fluid dynamics, heat transfer, solid mechanics, and materials behavior.  
• Experience supporting hardware development through design, analysis, build, integration, and test phases.  
• Demonstrated experience with rapid prototyping, iterative hardware development, and design optimization.  
• Experience collaborating with engineering, testing, and manufacturing teams to resolve technical challenges and meet system requirements.  
• Ability to evaluate technical trade-offs involving performance, size, weight, cost, and manufacturability.  
• Strong problem-solving skills, technical judgment, and ability to independently drive complex engineering projects in a fast-paced environment.  

• MS in Mechanical Engineering, Aerospace Engineering, or equivalent.  
• Direct turbojet engine or turbomachinery development experience.  
• Experience developing propulsion systems for aerospace, defense, or other high-performance applications.  
• Experience with additive manufacturing, design for additive manufacturing (DfAM), and advanced materials.  
• Familiarity with finite element analysis (FEA), computational fluid dynamics (CFD), and multiphysics simulation tools.  
• Experience with engine testing, instrumentation, data acquisition, and performance characterization.  
• Experience taking propulsion hardware from early-stage development through qualification or production.  
• Experience working in a greenfield, first-of-its-kind product development environment with aggressive development timelines.  

• Requires frequent standing, walking, and interaction across production and R&D work areas.
• May occasionally require extended or weekend hours to meet production deadlines.
• Work is performed in an office environment and requires the ability to operate standard office equipment and keyboards.
