R&D/Mechanical Engineer

Description The R&D Engineer will blend duties in mechanical design, thermodynamics, fluid flow and structural analysis. The role will focus on R&D of advanced battery power module technology to ensure performance, reliability and cost. The deliverables will require significant input into the mechanical design: structural and fluidic analysis, testing and validation, prototyping, specification creation and implementation, quality support, etc. The ideal candidate will have a passion for sustainability and the environment, will thrive in a fast-paced entrepreneurial setting, be self-motivated, and have an interest in disruptive, cutting-edge technology. Job Responsibilities: + Senior contributor to the mechanical design of stack and subsystem hardware (manifolds, flow fields, plates, frames, enclosures, seals) using 3D CAD and rigorous design control (models, drawings, specs, BOMs; GD&T). + Analyze and optimize thermal/fluid performance and structural integrity (pressure/temperature/vibration/thermal cycling) using FEA/CFD. Translate insights into robust design updates. + Engineer for manufacturability and reliability (DFM/DFA/DFR) across casting, machining, plastics (injection molding, extrusion, plastics welding), and sealing processes (welding, adhesives, gaskets). + Select materials compatible with electrolytes and corrosive environments; address creep, fatigue, and stress-relaxation mechanisms with appropriate safety margins and life predictions. + Correlate models to test: develop validation plans, define test articles/fixtures, analyze data, close the loop to simulation, and drive root-cause and corrective actions. + Collaborate across all engineering and supply chain teams to convert performance targets into durable, cost-effective designs ready for production. + Continuously improve cost, reliability, and serviceability while maintaining safety, compliance, and quality standards. Skills & Qualifications + B.S. in Mechanical Engineering (or related). + 5+ years of experience in mechanical design and analysis of complex electromechanical, fluid or electrochemical systems (or equivalent combination of graduate and industry experience). + Proficiency in 3D CAD (SolidWorks ideally, or equivalent) for parametric design, detailed drawings, and BOMs. + Strong foundation in thermodynamics, fluid mechanics, and solid mechanics, with hands-on FEA/CFD and tolerance stack-ups. + Developed detailed engineering drawings using GD&T principles per ASME Y14.5, incorporating a strong understanding of quality inspection methods to accurately define and verify critical-to-function (CTF) and critical-to-quality (CTQ) features. + Experience designing for corrosive or reactive fluids and hermetic sealing (welds, adhesives, gaskets). + Track record of cross-functional execution from concept to validated hardware (prototype pilot production). + Clear, concise communicator; self-directed; able to juggle multiple design workstreams. Preferred Qualifications: + M.S. in Mechanical, Materials Science, Energy Systems, or Chemical Engineering. + Experience in battery, fuel cell, or power-generation system design. + Demonstrated multiphysics experience (ANSYS, COMSOL, or equivalent) and test correlation. + Scaling from prototype to production; cost and reliability ownership. + Knowledge of electrolyte-compatible materials and corrosion mitigation. + Experience with pressure-bound assemblies and pressure vessel considerations. + Plastics and polymer component design for injection molding, extrusion, and plastics welding. + Hands-on experience with CNC/CAM and other fabrication and machining techniques, with a solid understanding of tolerances, tool paths, and manufacturability trade-offs. Role is primarily onsite, so local talent will be prioritized. Any nonlocal talent will need to relocate, potentially on their own, for consideration. #LI-MH3 Job Type & Location This is a Contract to Hire position based out of Tualatin, OR.
