Job description

Staff Mechanical Systems Engineer — Design-for-Manufacture LeadLocation: OnsiteA day in this roleYour morning starts with a quick sync between mechanical and electrical design. By mid-morning, you’re on the production floor, translating design intent into buildable reality—reviewing fixtures, walking an assembly cell, and hosting a DFM/DFA conversation that shaves minutes off takt time. After lunch, you jump into a prototype fit check, tweak a CAD model, and coordinate a rapid rework to validate a tolerance stack. You close the day by capturing lessons learned in the PLM system so the next iteration is smarter, simpler, and ready for scale.How you’ll contributeOwn the development of mechanical components and electromechanical assemblies from first concept through production, then continue with post‑launch cost and quality improvements.Act as the nexus between design engineering and factory operations, ensuring design decisions align with real manufacturing capabilities and line requirements.Lead DFM/DFA reviews to elevate manufacturability, assembly efficiency, ergonomics, automation readiness, and in-field serviceability.Roll up your sleeves during prototype builds—run fit checks, perform rework, leverage rapid prototyping, execute tests, troubleshoot issues, and resolve manufacturing blockers.Partner closely with technicians and cross‑functional engineers to build and validate early prototypes against aggressive development timelines.Capture and formalize manufacturing feedback, lessons learned, and design updates to drive continuous refinement and stronger future designs.What you bringBachelor’s degree in Mechanical Engineering or a closely related engineering field.7+ years of hands‑on product development for high‑volume electromechanical products.Deep mechanical fundamentals plus working knowledge of electrical systems and electro‑mechanical integration.Background designing/supporting wire harnesses, busbars, sensors, control panels, plastic parts, sheet‑metal components, and PCBA‑related assemblies.Fluency with modern 3D CAD, PLM, formal engineering documentation, and BOM control.Exceptional problem‑solving, communication, and organization; able to juggle multiple priorities on a fast‑paced production floor.Preferred qualificationsGD&T application, tolerance stack analysis, and experience with high‑volume manufacturing processes.Time spent in process/manufacturing engineering or direct production support.Exposure to battery systems, high‑voltage products, or similarly complex electromechanical platforms.Familiarity with CAN, LIN, and Ethernet communication protocols.Experience with rapid prototyping, design validation, root‑cause analysis, and production ramp.
