• Proficiency with CAD and analysis tools (e.g., SolidWorks, ANSYS, Abaqus, or similar)
• Working knowledge of engineering drawings, tolerances, and GD&T
• Strong problem-solving ability and clear technical communication skills
• Must be a U.S. person. No sponsorship can be provided for this role.

Preferred Experience

• Exposure to power, energy, industrial, aerospace, or heavy mechanical systems
• Experience selecting materials for high-load, high-temperature, or demanding environments
• Hands-on experience with hardware builds, testing, or experimental validation
• Background in one or more focus areas such as structures, mechanisms, heat transfer, or dynamics
• Familiarity with industry standards (ASME, ISO, API, or similar)
• Prior experience in nuclear or highly regulated industries is not required

Compensation & Benefits

• Competitive base salary with meaningful equity participation
• Comprehensive medical, dental, and vision benefits
