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
- Solid 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
- Strong 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
