NPSS Propulsion Systems Engineer; Lead

A day in the life

You start your morning refining an NPSS cycle model, validating steady-state predictions and setting up a transient run to probe operability margins. By midday, you translate system-level needs into verifiable requirements in our MBSE environment and collaborate with controls, aerodynamics, and mechanical teams to decompose and allocate them. In the afternoon, you debug a model convergence issue, tune the thermodynamic deck, and brief stakeholders on performance trade-offs that influence design decisions from concept through qualification.

Tomorrow, you’ll do it again—pushing the envelope of commercial and military propulsion.

What you will do Build, calibrate, and debug NPSS engine models to support performance and operability analyses.

Execute steady-state and transient thermodynamic studies to inform architecture, control schedules, and margins.

Apply MBSE practices to capture requirements and drive traceability from system objectives to component-level verifications.

Partner closely across disciplines to integrate results and guide engine development decisions.

What you bring4+ years analyzing gas turbine performance and operability.

Hands-on NPSS expertise—building, refining, and troubleshooting models (not just reviewing others’ outputs).Depth in thermodynamic cycle analysis, steady-state and/or transient.

Experience with MBSE and requirements decomposition.

Proven success collaborating with multi-disciplinary engineering teams.

Why this role Compensation: $58.65 per hour.

Hybrid work flexibility.

Direct impact on advanced aerospace engine programs.

Access to state-of-the-art NPSS and MBSE tool chains.

Influence across the lifecycle—from early concept to qualification.
