Job Title:

R& D Mechanical Engineer Job Description This R& D-focused Mechanical Engineer role focuses on the mechanical design and development of advanced battery power module technology to achieve high performance, reliability, and cost-effectiveness. You will apply expertise in mechanical design, thermodynamics, fluid flow, and structural analysis to create, analyze, and validate complex fluid or electrochemical systems. The position offers the opportunity to work on disruptive, cutting-edge technology in a fast-paced, entrepreneurial environment, contributing directly to sustainable energy solutions. Responsibilities Serve as a senior contributor to the mechanical design of stack and subsystem hardware, including manifolds, flow fields, plates, frames, enclosures, and seals, using 3D CAD tools and rigorous design control practices such as models, drawings, specifications, bills of materials (BOMs), and GD& T. Analyze and optimize thermal and fluid performance as well as structural integrity under pressure, temperature, vibration, and thermal cycling using FEA and CFD tools, and translate simulation insights into robust design improvements. Engineer components and assemblies for manufacturability and reliability (DFM, DFA, DFR) across processes such as casting, machining, injection molding, extrusion, plastics welding, and sealing methods including welding, adhesives, and gaskets. Select materials compatible with electrolytes and corrosive environments, and address creep, fatigue, and stress-relaxation mechanisms with appropriate safety margins and life predictions. Develop and execute validation plans, define test articles and fixtures, analyze test data, correlate results with simulations, and drive root-cause analysis and corrective actions to close the loop between modeling and testing. Collaborate closely with cross-functional engineering and supply chain teams to translate performance targets into durable, cost-effective designs that are ready for production. Continuously improve product cost, reliability, and serviceability while maintaining safety, compliance, and quality standards. Follow all job-required standards and safety protocols according to predefined processes and applicable regulations. Handle and move components and equipment as needed, including lifting up to 50 lbs unassisted, while using appropriate personal protective equipment. Essential Skills Bachelor's degree in Mechanical Engineering or a related field. 5+ years of experience in mechanical design and analysis of complex fluid or electrochemical systems, or an equivalent combination of graduate and industry experience. Proficiency in 3D CAD tools such as Inventor, SolidWorks, or equivalent for parametric design, detailed drawings, and bill of materials creation. Strong foundation in thermodynamics, fluid mechanics, and solid mechanics. Hands-on experience with FEA and CFD for structural, thermal, and fluid analysis. Experience performing tolerance stack-ups and applying GD& T principles per

ASME Y14.5.

Proven ability to develop detailed engineering drawings using GD& T with a strong understanding of quality inspection methods to define and verify critical-to-function (CTF) and critical-to-quality (CTQ) features. Experience designing systems that handle corrosive or reactive fluids and hermetic sealing solutions such as welds, adhesives, and gaskets. Demonstrated track record of executing projects from concept through prototype, pilot, and into production with validated hardware. Clear and concise communication skills, with the ability to work in a self-directed manner and manage multiple design workstreams simult...
