Senior Thermo-Mechanical Engineer

The role

You will own thermal management and the thermal energy budget for the Power Conversion System. This includes developing heat rejection architecture, sizing the recuperator, and managing temperature-related life-limited hardware.

What you will do

• Own thermal management and thermal energy budget of the Power Conversion System.
• Develop the heat rejection and cold-sink architecture.
• Size and integrate the recuperator and heat rejection.
• Define the thermal configuration including insulation, heat-loss budget, and personnel protection.
• Manage thermal interfaces and thermal transient requirements.
• Support test rig design and instrumentation placement.
• Engineer components for high-temperature and high-stress service.
• Develop inspection and maintenance plans for thermal-mechanically life-limited hardware.
• Work with Mechanical, Electrical, Safety, and Nuclear teams.

Required qualifications

• Bachelor's degree in Mechanical, Aerospace, Nuclear, or a related engineering discipline or 5+ years for Senior Engineer, including hands-on analysis, hardware design, build, and test
• Experience performing thermal analysis (hand calculations and FEA or CFD) to size, configure, or qualify hardware
• Experience designing thermal management hardware for high-temperature systems
• Experience sizing or integrating heat exchangers or a heat rejection path against real operating and ambient conditions
• Experience correlating thermal predictions against test data and revising a design based on the result
• Experience owning thermal interfaces or requirements across multiple subsystems

Nice to have

• Experience in the Nuclear, Aerospace, Automotive, Power Generation, Motorsports, or Oil and Gas industries
• Experience with recuperators, air-cooled or dry heat rejection, and ambient-dependent performance derating
• Experience selecting and designing high-temperature insulation systems
• Experience with transient thermal analysis of startup, shutdown, trip, and off-nominal cases
• Experience with thermal-mechanical fatigue, creep, and creep-fatigue interaction
• Experience with elevated-temperature design codes such as ASME BPVC Section III Division 5 or Section VIII Division 2 Part 5
• Experience with high-temperature metals and advanced materials, including nickel superalloys
• Experience specifying thermal instrumentation and using it to correlate models
• Experience developing inspection and maintenance plans for life-limited hardware, including NDE method selection
• Experience with thermal and structural analysis tools such as ANSYS Mechanical, Femap or NX Thermal, and/or CFD tools such as Fluent or Star-CCM+
