About The Role

About Build AIBuild AI is the data hyperscaler for Physical AI. We co-design hardware, collection, infrastructure, and research to scale the in-the-wild physical labor dataset by orders of magnitude. We learn from humans doing the real job, in real environments. Inflecting revenue, backed by top-tier investors and staffed by leading engineers, Build is becoming the bottleneck to solving physical labor.Job SummaryWe're hiring mechanical design in Shenzhen for the structures that make collection hardware real: enclosures, mounts, wearability, thermal, drop, and the parts a factory can tool. A generalist who can also do industrial design is strongly preferred.Key ResponsibilitiesOwn mechanical design of collection devices: enclosure, mount, stackup, fasteners, gaskets, how it survives a job siteCAD through DFM/DFA, drawings, tooling, and incoming quality with Shenzhen vendorsApply DFM so designs scale from prototype to volume; own soft and hard tooling conversations with vendorsWork with PCB on keepouts, connectors, and how the board lives in the object; work with ID on formDesign for wear: a device that is uncomfortable does not get hours of data. Validate with drop, shock, and field failuresIterate in the factory. Close loops on yield, rework, and field returnsTranslate industrial design into manufacturable parts (plastics, sheet metal, as needed)You may be a good fit if you have (Must-have qualifications)You've shipped mechanical parts into manufacturing: CAD (SolidWorks, Onshape, or equivalent), drawings, vendors, revisionsUnderstanding of DFM/DFA and of plastics and/or sheet metal at cheap, high-volume hardwareFine in Shenzhen and in factories. You measure success in devices that stay on people and keep recordingYou resist overbuilt mechanisms that cut how many units we can fieldStrong candidates may also have experience with (Nice-to-have qualifications)Industrial design skill (form, CMF, wearability). We would rather hire a generalist than a CAD-only specialistGD&T, injection molding, or experience with wearables / compact consumer hardwareTolerance, structural, or thermal analysis when it actually changes the designExperience working with ID on appearance surfacesBenefitsCompetitive payMedical, dental, and vision packages with generous premium coverage$500 per month credit for waiving medical benefitsHousing subsidy of $2k per month for those living within walking distance of the officeRelocation support for those moving to San Francisco (Financial District) or Shenzhen (Nanshan)Various wellness benefits covering fitness, mental health, and moreDaily lunch and dinner in our officeUnlimited compute budget subject to ROI justificationTravelHow we're differentBuild believes in the Bitter Lesson. We are betting early on learning from real human work at massive scale, and that the economies of scale of collection beat extra sensors and extra fidelity. Our addressable market is all physical labor, unlike many of our competitors.We are a fully in-person team in San Francisco (Financial District) and Shenzhen (Nanshan), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both and work across disciplines as <needed.Build> AI is an equal opportunity employer. We review every application. If you do not meet every bullet, still apply. Questions: <[email hidden]>
