About The Position

The NPSS Propulsion Performance Systems Engineer builds, calibrates, and troubleshoots NPSS engine models for performance and operability analyses. The role uses steady-state and transient thermodynamic studies to inform engine architecture, control schedules, and operating margins, and applies model-based systems engineering (MBSE) practices to capture requirements and maintain traceability from system objectives to component-level verifications. The engineer collaborates across disciplines and advises stakeholders on performance trade-offs that guide engine development from early concept through qualification, supporting commercial and military propulsion programs.

Requirements

• At least 4 years analyzing gas turbine performance and operability.
• Hands-on NPSS expertise building, refining, and troubleshooting models.
• Depth in thermodynamic cycle analysis, including steady-state and/or transient analysis.
• Experience with MBSE and requirements decomposition.
• Demonstrated success collaborating with multidisciplinary engineering teams.

Responsibilities

• Build, calibrate, and debug NPSS engine models for performance and operability analyses.
• Conduct steady-state and transient thermodynamic studies to inform architecture, control schedules, and margins.
• Use MBSE practices to capture requirements and drive traceability from system objectives to component-level verifications.
• Collaborate with controls, aerodynamics, mechanical, and other engineering teams to integrate results and guide engine development decisions.
• Brief stakeholders on performance trade-offs affecting design decisions throughout the lifecycle, from concept through qualification.

Benefits

• Medical, dental, vision, and life insurance.
• Short-term disability coverage.
• Additional voluntary benefits.
• Employee assistance program (EAP).
• Commuter benefits.
