What you will do

• Own the mechanical architecture, design, modeling, and iteration of next-generation manufacturing reactors.
• Translate chemical R&D concepts into robust, production-ready hardware through calculations, thermal modeling, structural FEA, and CFD.
• Develop 3D CAD layouts, core IP drawings, equipment datasheets, P&IDs, fabrication packages, and design-for-manufacturability solutions.
• Build lab- and pilot-scale test rigs, instrument prototypes, conduct validation testing, and lead design iteration.
• Direct external fabricators through tool build, factory acceptance testing, and site commissioning.
• Lead safety-by-design activities, HAZOP and Process Safety Management evaluations, and mentor junior engineering staff.

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering, or equivalent practical experience, plus 8+ years in mechanical design engineering, thermal/fluid hardware, or complex system development.
• Demonstrated ownership of hardware across the full lifecycle, from first-principles calculations and CAD through prototype build, testing, and field deployment, with core IP, modeling, and detailed design preferably kept in-house.
• Advanced proficiency in 3D CAD such as SolidWorks, NX, or equivalent.
• Deep knowledge of DFM/DFA and fabrication techniques including machining, high-temperature alloy welding, and pressure vessels.
• Experience creating fabrication drawing packages with GD&T, P&IDs, and datasheets.
• Strong expertise in heat transfer, fluid flow, and structural mechanics, with practical FEA/CFD experience using tools such as ANSYS or SolidWorks and back-of-the-envelope modeling.
• Hands-on experience assembling test stands, instrumenting prototype hardware, and conducting validation testing.
• Working knowledge of Process Safety Management, HAZOP reviews, and applicable industrial codes including ASME and NFPA.
• Ability to wear required PPE, move items up to 50 lbs with assistance, walk long distances, remain stationary for extended periods, reach low shelves, climb stairs or containment walls, and operate office equipment.
