Senior Propulsion Engineer

Description

Reusable systems are the key to seamlessly connecting Earth and space. Stoke’s Engines Team is developing reusable LNG/LOX full-flow staged combustion first stage engines and a LH2/LOX expander second stage engine for our launch vehicle, Nova. As a Senior Engines Design Engineer, you will have extreme ownership over all aspects of a components design, analysis, manufacturing, testing, and validation for an advanced reusable rocket engine (components like thrust chambers, reentry heat shields, injectors, turbomachinery, actuators, ignitors, etc).

Responsibilities

• Own various component designs across Stoke’s engines. Examples may include: regeneratively cooled thrust chambers, reentry heat shields, injectors, turbomachinery, actuators, ignitors, cryogenic flexible feedlines, engine layouts, heat exchangers, engine gimbals, thrust structure, test rigs, etc.
• Create models, drawings, and coordinate manufacturing of various components for the engines team.
• Develop and execute qualification test plans to ensure readiness for flight (proof, vibration, thermal cycle, life cycle, flow testing, hotfire, etc).
• Present and clearly communicate design, analysis, and test results.
• Own root cause investigations and redesigns to improve reliability or manufacturing throughput.
• Track risks and execute appropriate mitigation plans.
• Develop and maintain test requirements and test plans.
• Manage project schedules, risk, and budget.

Qualifications

• Exceptional command of fundamentals.
• Experience with detailed mechanical design including machined parts, additive parts, weldments, fasteners, seals, and translating/rotating assemblies.
• Experience in designing, analyzing, and testing rocket engine components; thrust chambers, regenerative cooling channels and heatshields, injectors, turbomachinery, actuators, ignitors, gimbals, feed systems, engine layouts, etc.
• Experience in GD&T, axial/radial tolerance stackups, and material selections.
• Proficiency in heat transfer, compressible and incompressible flow, and cryogenics.
• Proficiency with CAD tools (Siemens NX preferred).
• 8+ years of experience in design, build, and testing of rocket engine components.
• Excellent written and verbal communication.
• Bachelor’s degree in mechanical or aerospace engineering, or similar.
• Willing to relocate to Seattle, WA.
