Hardware Prototype and Test Technician

CHEFFY is a Bay Area-based startup building robots for the home kitchen, starting with breakfast! Our first product, EGOR, has received over $1.4M in pre-orders from 5,000 customers on Kickstarter and our website.

We're looking for a hardware prototyping generalist to help build, refine, and test our hardware as we move through engineering validation and prepare for manufacturing. This could be a great opportunity to contribute directly to a consumer hardware product and be a part of the journey from prototype to mass production.

Work may include:

• FDM and resin 3D printing of engineering test parts, fixtures, and component variations

• Sanding, finishing, drilling, tapping, fitment, and mechanical assembly

• Building simple test jigs and fixtures

• Basic soldering, crimping, wiring, and electronics assembly

• Durability and repeated-cycle testing

• Measuring forces, temperatures, dimensions, and other hardware performance

• Testing induction systems, cooking performance, recipes, and toaster functionality

• Making simple CAD or component modifications

• Using common shop, hand, and power tools

• Clearly documenting measurements, observations, photos, and results

• Potentially helping coordinate with suppliers and manufacturing partners

You should already be comfortable with:

• FDM 3D printing and troubleshooting

• Resin 3D printing and post-processing

• CAD modifications, ideally in Fusion 360 and/or SolidWorks

• Mechanical assembly, fitment, sanding, drilling, and general fabrication

• Soldering, wire stripping, and crimping

• Calipers, multimeters, and other basic measurement/test tools

• Common shop, hand, and power tools such as a drill press, rotary tools, and sanders

Experience with CNC machining, electronics, jig/fixture design, or other fabrication methods is a plus. 

We need someone who is confident in building, tweaking, and testing hardware, and can take the initiative to solve multidisciplinary engineering challenges.

We welcome candidates from a range of backgrounds, including prototype and engineering technicians, mechanical and electrical engineers, product development professionals, and experienced builders. Demonstrated hands-on capability, practical problem-solving, and the ability to work independently matter more to us than a particular degree or job title. Applicants must be 18 or older.

Location: Fremont, CA - in person

Pay: $30-45/hour depending on experience

Hours: Flexible, approximately 10-20 hours/week

We'll start with a small paid trial work session using a real CHEFFY build/test task. If it's a good fit on both sides, the opportunity can extend into ongoing part-time work.
