Design Engineer - Thermal Systems - Propulsion

Are you a design engineer with strong experience of leading the design development and validation of thermal management systems such as coolant/oil loops, heat exchangers, valves, pumps, regulators?

Would you like make an impact on a clean-sheet aircraft propulsion program, designing and delivering novel hardware?

You will get the opportunity to further your skills

Architecting and designing thermal systems from scratch, such as coolant loops or oil circuits, heat exchangers, valves, pumps, regulators.

Generate CAD models and detailed drawings with GD&T (Siemens NX preferred).

Develop 1D fluid network models and use hand calcs and CFD to predict transient behaviour, sensitivities, and performance.

Analyzing thermal interfaces, conduction paths, and heat loads, and define instrumentation strategies to validate models.

Build prototypes, write test plans, run experiments, and anchor models with real data.

Drive design reviews and own technical decision-making from prototype through flight qualification.

You will need to have

5-15 years of experience in thermal and fluid systems-preferably in aerospace / space propulsion, automotive, or similar complex environments.

A mechanical design engineer with a thermal bias-someone who's built hardware, not just simulated it.

Proficient in CAD (ideally Siemens NX), drawing creation, and 1D/0D system modelling.

You've owned full systems: from blank sheet to assembly, integration, and test.

Comfortable in fast-moving, high-accountability teams where design ownership means end-to-end responsibility.

Bonus points if you've worked within a high technology start up environment where you have tested early, iterated fast and made decision.

You'll get

Competitive salary + transparent stock option plan

Comprehensive medical, dental, vision coverage + FSA

401(k) program

Flexible PTO, paid holidays, and sick time

Permanent
