Thermal-Mechanical Engineer II — High-Temp Power Systems

Antares; Torrance, Northern (CA, KY); Hybrid; USD 115,000 - 150,000; Full time

Job summary

Antares seeks a Thermo-Mechanical Engineer II to own the thermal management of the Power Conversion System, guiding the heat budget from the overall system to insulation on hot sections. You will define the heat rejection and cold-sink architecture, size the recuperator, and set thermal configurations to meet life-time and safety requirements.

You will drive instrumentation placement, validate models against real data, and collaborate with Mechanical, Electrical, Safety, and Nuclear teams to

Qualifications

• Bachelor's degree in Mechanical, Aerospace, Nuclear, or related engineering discipline.
• 2+ years of full-cycle engineering experience.
• 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.

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.
