Aerospace Propulsion Combustion & Thermal Engineer

Blisk Dynamics; Long Beach (CA); On-site; USD 160,000 - 220,000; Full time

Benefits offered by this job

Premium Healthcare Coverage

Life Insurance (Company Paid)

Job summary

Blisk Dynamics seeks a combustion and thermal-fluids engineer to own the reacting-flow and thermal heart of our next-generation gas turbine engine. You will lead from first sizing calculations to a running rig, shaping combustion, heat transfer, and overall engine performance.

You will build full-engine thermal models, run CFD on compressors and turbines, and test hardware while collaborating across design, analysis, and test teams. This role offers rapid impact in a small, fast-moving team.

Qualifications

• B.S. or M.S. in mechanical, aerospace, or related discipline; roughly 5–7+ years of relevant experience.
• Fundamentals in thermodynamics, fluid mechanics, combustion, and heat transfer.
• Ability to build full-engine or full-system thermal models with defensible assumptions.
• Hands-on CFD in ANSYS (Fluent/CFX) or comparable, preferably on turbomachinery or reacting flows.
• Hands-on hardware testing beyond simulation.
• Clear technical communication and data-driven reasoning.
• Fluent with modern AI tools while maintaining engineering judgment.

Responsibilities

• Design and develop the combustion system — combustor, fuel injection and atomization, ignition and relight — from concept through test and into production.
• Build and own the full-engine thermal model: secondary and cavity flows, conjugate and convective/radiative heat transfer, and conduction throughout.
• Run CFD across the machine — compressor and turbine aerodynamics, combustor reacting flow, ducts and secondary flows — and turn the results into design changes.
• Support cycle- and system-level modeling: performance decks, station analysis, and the thermodynamic trades that size the engine.
• Take hardware to the test stand: instrument it, run it, reduce the data, and reconcile predictions against measurement.
• Move fluidly across build and test, picking up whatever the program needs.
