Lead Propulsion Engineer (Methalox Focus) Overview We’re looking for a Head / Lead Propulsion Engineer to own the design, development, and delivery of a liquid rocket propulsion system from early-stage build through to launch. This role combines deep technical ownership with team leadership, operating at system level across the full engine.
Key Responsibilities Own propulsion system architecture and development strategy
Lead design across injector, combustion chamber, and feed systems
Make system-level trade-offs across performance, reliability, and manufacturability
Build and lead a multidisciplinary propulsion team
Drive testing strategy from component through to full engine hot fire
Diagnose failures and iterate designs quickly
Interface with structures, avionics, and manufacturing teams
Required Experience ~10+ years in liquid rocket propulsion




Strong hands-on experience with engine hardware and testing
Proven ability to operate across full propulsion system, not just one component
Prior experience leading teams or coordinating multi-disciplinary efforts
Robust grounding in fluid dynamics, thermodynamics, and combustion
Technical Requirements Strong experience with injector design / development (critical)
Solid understanding of combustion chamber behaviour
Working knowledge of turbopumps / feed systems
Experience with cryogenic propellants (methane, hydrogen, LOX)
What Doesn’t Work Pure analysis / simulation backgrounds
Narrow specialists with no system-level understanding
Startup “titles without depth” profiles
