Director - Mechanical Engineering (Fusion Energy)

Location: Kearny, New Jersey, United States; Workplace: On-site

Salary: $135,000–$235,000 per year

Company

hirify.global is developing commercial fusion energy systems using computer-controlled arrays of planar coils and stellarator physics.

What you will do

• Own the technical baseline for primary and secondary mechanical fusion systems from requirements and design through analysis, verification, manufacturing, commissioning, and operation.
• Lead structural, thermomechanical, thermal, electromagnetic, nuclear, vacuum, and cryogenic system-level design trades.
• Define and maintain requirements, interface controls, configuration baselines, assembly sequences, and integration plans.
• Drive feasibility analysis for normal operation, off-normal events, and transients, including technical risk mitigation.
• Partner with manufacturing and fabrication engineering to address tight tolerances, inspection, assembly, and stellarator-specific geometry challenges.
• Build and lead an integrated multidisciplinary engineering team, defining work packages, priorities, and technical standards.

Requirements

• 15+ years of experience in mechanical engineering, nuclear engineering, or a closely related field involving large-scale, high-performance hardware systems.
• Deep expertise in at least two areas including structural analysis, thermal-hydraulic analysis, vacuum systems, cryogenic engineering, nuclear engineering, high-heat-flux components, or manufacturing engineering.
• Experience managing multidisciplinary hardware development from concept through fabrication and test.
• Strong knowledge of materials behavior and manufacturing processes for demanding mechanical systems.
• Proficiency with CAD, FEA, and PLM systems; NX and ANSYS are preferred tools.
• Bachelor’s degree or higher in mechanical engineering, aerospace engineering, physics, or a related field.

Nice to have

• Experience with first-of-a-kind hardware development in a startup environment.
• Experience building and leading high-performing technical teams.

Culture & Benefits

• Comprehensive medical, dental, and vision benefits.
• Employee equity stock options.
• 20 days of paid time off.
• Work with a creative, multidisciplinary team solving complex fusion-energy engineering problems.
• Equal opportunity workplace committed to diverse backgrounds and perspectives.
