Mechanical Engineer, New Product Development

Overview As a New Product Development Engineer at Copper, you’ll contribute to creating the next generation of home appliances for an electrified future — supporting products from early concepts through production-ready designs. You’ll help develop mechanical systems and components, translating ideas into manufacturable, reliable hardware that can ship into real homes. This role spans the full product development cycle: concept exploration, engineering development, prototyping, validation, and production readiness. You’ll contribute to generating and evaluating design concepts, then help drive selected designs through detailed design, testing, supplier engagement, and manufacturing scale-up. You’ll work closely with electrical, firmware, industrial design, operations, and supply chain teams to bring new products from idea to production. As part of a growing hardware team, you’ll play a meaningful role in both what we build and how we build it, while continuing to develop your technical depth and product development skills. We value diversity and are committed to building a team that reflects a wide range of backgrounds, experiences, abilities, and perspectives. We’re especially focused on fostering an inclusive workplace where everyone can contribute to our shared mission. This is a full-time position expected to be in-office 4 days per week with 1 day flexible for in-office or remote work. Our office is located in Berkeley, CA. What you'll do Contribute to the mechanical design and development of new products and subsystems, supporting projects from concept through production. Participate in early-stage concept exploration by generating ideas and helping evaluate different design approaches. Translate product requirements into engineering designs Support designs through the development lifecycle, including detailed design, prototyping, validation, and production ramp. Create and maintain CAD models, detailed drawings, and documentation for components and assemblies. Build and test prototypes using in-house tools and external vendors, iterating based on results. Apply knowledge of materials and manufacturing processes to make sound design decisions Support design-for-manufacturability (DFM) and design-for-assembly (DFA) efforts across common processes such as injection molding, machining, and sheet metal. Collaborate with suppliers, operations, and manufacturing teams to refine designs and support builds. Troubleshoot design and build issues, identifying root causes and implement improvements. What you'll bring 2–5 years of hands-on experience in mechanical or product development engineering Demonstrated experience contributing to hardware products through development and/or early production. Solid foundation in engineering fundamentals, including materials, mechanics, and basic failure modes. Working knowledge of common volume manufacturing processes (e.g., injection molding, machining, sheet metal) and their design considerations. Proficiency in CAD and creating clear, accurate drawings; exposure to GD&T is a plus. Experience with prototyping and iterative design (e.g., 3D printing, laser cutting, quick-turn fabrication). Ability to approach problems methodically, apply sound engineering judgment, and seek guidance when needed. Strong communication skills and ability to collaborate effectively with cross-functional teams. Organized and detail-oriented, with the ability to manage multiple tasks in a fast-paced environment. Eagerness to learn, take feedback, and grow as part of a product development team. Location This is a full-time position expected to be in-office 4 days per week with 1 day flexible for in-office or remote work. Our office is located in Berkeley, CA. Compensation & Benefits The salary range for this role is $105,000 - $125,000. We are committed to equitable compensation, and we offer a generous benefits package to make sure you have the support you need. We cover 100% of the premiums for our employees and 5
