- Partner with engineering leadership and cross-functional teams to resolve complex thermal and fluid-related design challenges.
Thermal and Fluid Analysis
- Lead aerothermal analyses for combustion chambers, nozzles, turbomachinery, ducts, valves, and other thermal-fluid systems.
- Develop and execute high-fidelity thermal, CFD, and convective or film cooling analyses to predict component environments and support design decisions.
- Define, maintain, and improve engine-level thermal environments, margin assessments, and boundary conditions for use by structural and materials engineering teams.
- Interpret analysis results and translate findings into actionable design recommendations, risk assessments, and performance improvements.
Program Execution and Test Support
- Plan, prioritize, and execute aero-thermal-fluids analysis activities in support of program milestones, design reviews, and hardware maturation.
- Support test campaigns by analyzing thermo-fluid data, correlating analytical predictions with hot fire results, and recommending design or operational changes.
- Identify technical risks, uncertainties, and model limitations early, and work with program teams to develop mitigation plans.
- Contribute to design validation, anomaly resolution, and continuous improvement of analytical methods and processes.
Communication and Collaboration
- Collaborate closely with design, materials, test, manufacturing, and program teams to ensure thermal robustness and mission reliability.
- Prepare and present technical reports, design review content, and formal documentation to internal and external stakeholders, including customers and program leadership.
- Clearly communicate assumptions, results, recommendations, and technical tradeoffs to support informed decision-making.
Team Development
- Mentor earlier career engineers through technical guidance, coaching, and knowledge sharing.
- Support the development of team capability in aerothermal analysis methods, tools, and engineering judgment.
- Promote strong engineering practices, analytical rigor, and continuous learning across the organization.
