Mechanical Design Engineer II - High-Temp Power Systems

Antares; Los Angeles (CA); On-site; USD 115,000 - 150,000; Full time

Job summary

Antares, located in Torrance, CA, seeks a Mechanical Design Engineer II to design the Power Conversion System hardware, including turbomachinery interfaces, high-temperature components, and pressure boundaries. You will move from concept through fabrication, integration, and test, coordinating with reactor and safety teams.

The role requires a BS in Mechanical/Aerospace, 2+ years full-cycle design experience, and experience with pressure-retaining hardware, GD&T, and CAD tools such as NX/ANSYS.

Qualifications

• Bachelor's degree in Mechanical, Aerospace, or a related engineering discipline.
• 2+ years of full-cycle design engineering experience.
• Experience designing pressure-retaining or leak-tight fluid hardware and supporting pressure and leak verification.
• Experience releasing production-intent mechanical drawings and models for fabrication, including GD&T and tolerance stack-up.
• Experience designing hardware for elevated-temperature or high-stress service, including material selection.
• Experience working the mechanical interfaces between multiple components integrated into a single assembly.

Responsibilities

• Own the mechanical arrangement and pressure budget of the Power Conversion System and close the loop with cycle performance on parasitic losses.
• Design the working-fluid pressure boundary including piping, joints, penetrations, and isolation with leak-tightness and pressure retention as first-class requirements of a closed cycle.
• Define the mechanical arrangement, maintenance architecture including skid or module arrangement, supports, anchors, and alignment of the rotating machinery, accounting for thermal growth, machinery loads, safety, transport, and seismic conditions.
• Manage mechanical interfaces to 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.
• Perform design-for-manufacturability and assembly assessments, including assembly sequence, access, maintainability, and field installation.
• Work with Mechanical, Electrical, Safety, and Nuclear teams to ensure the designs meet the overall objectives and requirements.
