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
