Propulsion Design Engineer - Thermal

16 Days Old

Join a team of elite engineers revolutionizing aerospace propulsion. At Astro Mechanica, we're building next-gen turboelectric adaptive jet engines in a fast-paced, pragmatic, and highly technical environment. We value ownership, hands-on problem solving, and first-principles thinking.
We're looking for a Propulsion Design Engineer who can take full ownership of thermal system design - from concept through flight. You'll be responsible for designing, modeling, prototyping, and validating thermal and fluid systems critical to the performance of our engines.

What You'll Do:

Design and model thermal systems in CAD (NX), generate drawings and apply GD&T
Build 1D fluid network models and optimize components using CFD and hand calcs
Size and select components: pumps, heat exchangers, valves, etc.
Analyze heat loads, interface temps, and anchor models with test data
Lead design reviews, prototype builds, testing, and data analysis

What We're Looking For:

5+ years experience in propulsion or complex thermal/fluid systems
Strong in thermodynamics, heat transfer, and system integration
Skilled in NX CAD, CFD tools, and 1D modeling (e.g. Thermal Desktop, Simcenter)
Comfortable in a hands-on, fast-paced, collaborative environment
Proactive mindset with high attention to detail

Perks:

Full medical, dental, and vision
401(k) + equity
Flexible PTO
Weekly team lunches & swag
Office-first culture for deep collaboration
