Job summary

Copper is seeking a New Product Development Engineer to contribute to the next generation of home appliances for an electrified future. You will help develop mechanical systems and translate ideas into manufacturable hardware, from concept through production design.

You’ll work with electrical, firmware, industrial design, operations, and supply chain teams to take products from idea to production, while growing technical depth and product development skills in a growing hardware team.

Qualifications

• 2–5 years hands‑on experience in mechanical or product development engineering.
• Solid foundation in engineering fundamentals including materials, mechanics, and failure modes.
• Working knowledge of volume manufacturing processes (injection molding, machining, sheet metal) and design considerations.
• Proficiency in CAD and detailed drawings; GD&T exposure is a plus.

Responsibilities

• Contribute to mechanical design and development of new products and subsystems from concept through production.
• Participate in early-stage concept exploration; generate ideas and evaluate approaches.
• Translate product requirements into engineering designs.
• Support designs through development lifecycle: detailed design, prototyping, validation, and production ramp.
• Create and maintain CAD models, drawings, and documentation for components and assemblies.
• Build and test prototypes using in-house tools and external vendors; iterate based on results.
• Apply materials and manufacturing process knowledge to sound design decisions.
• Support DFA and DFM across processes like injection molding, machining, and sheet metal.
• Collaborate with suppliers, operations, and manufacturing to refine designs and support builds.
• Troubleshoot design and build issues, identify root causes, and implement improvements.

Job description

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 implementing 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 50% of the premiums for their dependents on our base plans for medical, dental, and vision insurance. We offer a 401(k) plan for employees to contribute to, in addition to many other benefits. Every employee, regardless of gender identity or expression, is eligible for 16 weeks of paid parental leave after three months of employment (eight weeks through Channing Copper and eight weeks CA Paid Family Leave).

Equal Employment Opportunity

We are committed to creating an equitable and inclusive environment for all our employees and are seeking to build a team that reflects the diversity of the people we hope to serve with our products. We are proud to be an equal opportunity employer.
