What You’ll Do

As a Sr. Mechanical Engineer, New Product Introduction, you will work on engineering efforts to bring products from the lab into mass production. Your primary objective will be designing, commissioning, and improving the machines used in the Stack Forging process.

A skilled mechanical engineer with expertise in machine design and a deep understanding of reliability and safety. You have experience developing complex machines from concept to execution, solving tough engineering challenges along the way. You take full ownership of your projects, driving them forward independently while maintaining a strong sense of urgency. You know when to pivot, prioritize, and adapt to shifting demands to keep progress on track.

This role requires a high degree of technical ownership, cross‑functional collaboration, critical thinking for root cause analysis, and the ability to thrive in a fast‑paced environment. The position generally requires a commitment of 4 days onsite per week.

• Responsibilities are subject to change based on shifting business needs
• Clean slate design of the machines in the Stack Forging manufacturing system, including automated equipment for material preparation, cutting, inspection, bonding, and assembly
• Run design processes with requirements, specifications, concept generation, concept down‑selection, and design reviews
• Document and communicate design process and decisions
• Drive improvement of overall equipment efficiency, manufacturing tolerance, process stability, process monitoring, machine reliability, and automation
• Refine and revisit machine requirements with cross‑functional teams from product, process, software, and operations
• Proof‑of‑concept calculations and benchtop testing to inform design decisions
• System and sub‑system level design and analysis; utilizing parametric modeling to evaluate trade‑offs
• Own and update subsystem designs, BOM, specifications, CAD models, and drawings
• Select and manage external vendors for components and subsystems
• Statistical analysis for assembly tolerance stack‑up and perform root‑cause analyses
• Mentor early‑career engineers
