Lead Mechanical Engineer

The role

The Lead Mechanical Engineer will define and build next-generation reactor platforms to scale energy chemistry into mass production. This role involves inventing, modeling, and scaling complex fluid, thermal, and mechanical systems.

What you will do

• Own mechanical design, modeling, and iteration of next-generation manufacturing reactors
• Execute calculations, thermal modeling, and structural FEA/CFD to validate reactor performance
• Invent leaner, safer, and higher-throughput reactor architectures
• Author complete engineering packages including 3D CAD layouts, IP drawings, datasheets, P&IDs, and fabrication packages
• Build lab/pilot-scale test rigs and validate design concepts through physical testing
• Direct external fabricators through tool build, factory acceptance testing, and site commissioning
• Integrate safety-by-design principles and lead HAZOP and Process Safety Management evaluations
• Mentor and coach junior engineering staff

Required qualifications

• Bachelor's or Master's degree in Mechanical Engineering or equivalent practical experience
• 8+ years in mechanical design engineering, thermal/fluid hardware, or complex system development
• History of driving hardware through the full lifecycle from calculations and CAD to prototype build and field deployment
• Advanced proficiency in 3D CAD (SolidWorks, NX, or equivalent)
• Deep knowledge of DFM/DFA and fabrication techniques including machining, high-temp alloy welding, and pressure vessels
• Experience generating fabrication drawing packages (GD&T, P&IDs, datasheets)
• Expertise in heat transfer, fluid flow, and structural mechanics
• Practical experience using FEA/CFD simulation tools (e.g. ANSYS, Solidworks)
• Hands-on experience assembling test stands, instrumenting prototype hardware, and conducting validation testing
• Working knowledge of Process Safety Management (PSM), HAZOP reviews, and applicable industrial codes (ASME, NFPA)
• Ability to wear personal protective equipment including lab coat, gloves, safety glasses, and steel toe safety shoes
• Ability to move items up to 50 lbs with assistance, move long distances, reach low shelves, and climb stairs

Nice to have

• Background in high-stakes aerospace propulsion, consumer hardware innovation, or advanced process equipment

Benefits

• Total Rewards package including benefits, perks, and equity
