Mechanical Engineer, New Product Development

Copper is a home appliance company that designs and manufactures induction cooking ranges built for easy electrification of residential kitchens. Their flagship product, Charlie, is described as the world's first battery-equipped induction range, featuring an integrated 5 kWh battery that allows the appliance to plug into a standard 120-volt household outlet without requiring costly electrical upgrades or rewiring. This makes the transition from gas cooking to induction accessible to a much broader range of homeowners and renters. Copper's mission is rooted in accelerating the shift away from fossil fuel-based appliances in the home, particularly gas stoves, which contribute to indoor air pollution and greenhouse gas emissions. By eliminating the traditional barrier of expensive electrical panel upgrades, Copper lowers the cost and complexity of home electrification, directly supporting decarbonization goals in the residential sector. The company positions its product as a practical climate solution that does not require significant infrastructure investment. What makes Copper distinctive is its combination of battery storage technology with induction cooking in a single consumer appliance, a novel approach in the home appliance market. The product has attracted attention from culinary figures and everyday consumers alike, and Copper serves both individual homeowners and multifamily building operators, reflecting a broad strategy to scale clean cooking adoption across different housing types.

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.
