10+ years expCopperhome is a company focused on electrifying homes with clean energy through innovative electric appliances. As a Mechanical Engineer, you will own the mechanical design process from concept to production, collaborating with cross-functional teams to deliver reliable hardware solutions.
Electrical & Electronic Manufacturing
Responsibilities
Own major mechanical systems and subsystems from early concept through production, ramp, and real-world use (including the messy parts in between)
Take on ambiguous, high-impact problems and turn loose goals into clear technical direction, concrete plans, and shipped hardware
Act as a technical leader on cross-functional projects, working closely with electrical, firmware, industrial design, operations, quality, and service to deliver integrated, real-world solutions
Make strong engineering tradeoffs using first-principles thinking, balancing performance, reliability, manufacturability, cost, schedule, and customer experience
Stay hands-on: design parts, build prototypes, review drawings, debug issues on the bench, and support builds on the factory floor
Drive designs toward manufacturable, scalable solutions, partnering with suppliers and operations through pilot builds, production readiness, and iteration
Identify where our tools, processes, documentation, or testing break down — and help fix them. Create structure where none exists
Mentor engineers across the team through design reviews, technical problem solving, and day-to-day coaching, raising the bar for engineering judgment and execution
Step in as a project or subsystem lead when needed, helping align contributors, keep momentum, and unblock progress
Investigate tough production and field issues, dig into root causes, and drive fixes all the way through validation
Contribute beyond your immediate projects by helping shape how we design, build, test, and ship hardware as the company scales
Qualification
Required
B.S. or M.S. in Mechanical Engineering or a related field
10+ years of progressive, hands-on experience in product development, with a proven track record of executing and successfully shipping complex hardware products from initial concept to production
Good command of engineering fundamentals, design concepts, and detailed drawing creation, with the ability to break down problems to first principles
Experience in a diverse range of manufacturing processes (e.g., injection molding, die casting, stamping, machining, extrusion) and their associated design constraints and cost drivers
Strong communication skills, both written and verbal, and ability to communicate technical concepts to cross functional teams
Experience with rapid prototyping tools (waterjet, laser cutter, 3D printer), as well as quick turn manufacturing in order to rapidly evaluate designs
Ability to prioritize work, and operate independently, knowing how to ask for help when needed
Excellent organizational skills, creating structure and documentation as you work
Proven ability to work well with vendors
