Senior Thermal-Mechanical Engineer, High-Temp Power

Industrious Ventures; Torrance, Northern (CA, KY); Hybrid; USD 140,000 - 185,000; Full time

Job summary

Antares in Torrance, CA is seeking a Thermal-Mechanical Engineer for Integration of the Power Conversion System. You will own how heat moves through the PCS, from overall thermal budget to insulation on a hot-section, and lead heat-rejection and cold-sink architecture.

The role requires hands-on analysis, hardware design, and testing, with experience in high-temperature cycles and thermal fatigue; collaboration with Mechanical, Electrical, Safety, and Nuclear teams.

Qualifications

• Bachelor's degree in Mechanical, Aerospace, Nuclear, or a related engineering discipline.
• 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, such as insulation systems, heat-loss budgets, or thermal isolation
• 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

Responsibilities

• Own thermal management and thermal energy budget of the Power Conversion System and close the loop with cycle performance on parasitic losses.
• Develop the heat rejection and cold-sink architecture, sizing and integrating the recuperator and heat rejection against site and ambient conditions.
• Define the thermal configuration including insulation selection and design, heat-loss budget, surface temperatures, instrumentation, and personnel protection.
• Manage thermal interfaces and thermal transient requirements for major PCS components, reactor, and safety systems.
• Support test rig design and instrumentation placement. Utilize collected data to improve component life and performance.
• Engineer components for high-temperature and high-stress service using metals and advanced materials, in partnership with materials and structural analysis.
• Work with the team to develop inspection and maintenance plans that manage risk on thermal-mechanically life-limited.
• Work with Mechanical, Electrical, Safety, and Nuclear teams to ensure the designs meet the overall objectives and requirements.
