Job Description:

We are seeking an Aero-Thermal-Fluids engineer to provide technical leadership in the analysis, prediction, and optimization of aerothermal environments for liquid rocket engines and propulsion systems. This role leads advanced thermal and fluid analysis efforts to ensure propulsion hardware meets performance, durability, and mission requirements.

The ideal candidate brings deep experience in aero-thermal-fluids engineering and has a strong track record of leading complex technical work across development and production programs. This individual will serve as a technical authority in aerothermal modeling methods and tools, guiding design decisions through high-fidelity analysis and strong cross-functional collaboration.

This position requires a hands‑on technical leader who can balance deep analytical expertise with program execution, communication, and mentorship. The successful candidate will be proactive, organized, and highly effective at driving technical rigor while supporting team development.

This is an opportunity to play a critical role in shaping propulsion system performance, thermal robustness, and engineering excellence within an advanced aerospace organization.

Essential Functions:

Technical Leadership

• Provide expert technical leadership in the analysis, prediction, and optimization of aerothermal environments for liquid rocket engines and propulsion systems.
• Serve as a technical authority on aerothermal modeling methods, tools, assumptions, and best practices.
• Lead aero-thermal-fluids analysis activities across development and production programs.
• 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.

Job Requirements:

• Provide expert technical leadership in advanced analysis, prediction, and optimization of aerothermal environments for liquid rocket engines and propulsion systems
