San Francisco, California, United States
I’m a design engineer committed to developing novel, relevant, and exciting hardware products. I've worked across the engineering development cycle from blank sheet to production ready. https://www.williamplummer.com/

Took a few months to tinker, relax, and generally put roots down again after returning to SF
Automating human cell growth!
I worked as lead designer of the cleaning head systems on the flagship autonomous cleaning robot. The work was immensely diverse and involved taking the systems - which comprise hundreds of components and multiple physics domains - from a crude prototype to a scalable and elegant solution. I designed collectively thousands of prototype parts, empirical tests, and system models to perfect system efficacy, reliability, and to optimise for scalability. This work culminated in the production design, which saw me develop hundreds of molded parts, custom motorised systems, and user-facing mechanisms, taking each from blank sheet to optimised production tooling with vendors across the world. Being a startup setting, I had the opportunity to work on sourcing, internal process development, manufacturing, and many more tangents to the core engineering process with an incredibly talented small team.
I worked with the High-Voltage Mechanical team, splitting my time between a major motorsports inverter design project and the production design of the Air inverter. Working with a lean team of experts (internal and external) I worked to architect, prototype and detail a suite of electromechanical systems - from molded, soldered, machined, and everything in between - into an impossibly energy dense inverter for the Formula E Gen3 FPK units. The scope of work included early ideation, concept detailing, early prototyping and pre-production verification testing covering performance, electrical safety and mechanical robustness. On the production inverter, I owned the design of numerous molded plastic parts. I sustained these designs through multiple tooling changes, verification tests, and early production builds.
