We're vertically integrated across hardware, manufacturing, logistics, collection, and model training to scale the physical labor dataset orders of magnitude faster than anyone in the world.\nJob Summary\nWe’re hiring generalist software engineers who can work across the company. This seat finds the gap, ships in days not weeks, and moves on. One week you might build a data pipeline; the next a hardware integration script, an internal tool, or a customer-facing API. The only constant is a problem that is time-sensitive and business-critical.\nKey Responsibilities\nDetect the highest-leverage gap that week - ingest, APIs, orchestration, field tools, hardware glue - and ship production-quality code for it\n\nBuild backend services and APIs for the data platform and the customer-facing product\n\nWrite processing and validation pipelines for incoming in-the-wild datasets\n\nScript integrations between collection devices, cloud infrastructure, and software services\n\nDesign interfaces and developer workflows that the rest of the company actually uses\n\nWork cross-functionally with research, Shenzhen hardware, and ops without waiting for a spec\n\nYou may be a good fit if you have (Must-have qualifications)\nStrong full-stack skills; fluency in Python and at least one of TypeScript, React, Go, or C++\n\n1-5+ years shipping software end to end, ideally in a 0→1 or startup environment\n\nYou ramp quickly in unfamiliar codebases and problem domains\n\nBias toward action and comfort with incomplete information\n\nExperience shipping where the role was not clearly defined\n\nStrong candidates may also have experience with (Nice-to-have qualifications)\nExperience across backend, frontend, data, infra, and scripting\n\nHardware-adjacent, AI, or large-scale data systems\n\nPrior startup experience during hypergrowth\n\nInfrastructure or DevOps (Linux, containers, cloud)\n\nBenefits\nCompetitive pay\n\nMedical, dental, and vision packages with generous premium coverage\n\n$500 per month credit for waiving medical benefits\n\nHousing subsidy of $2k per month for those living within walking distance of the office\n\nRelocation support for those moving to San Francisco (Financial District) or Shenzhen (Nanshan)\n\nVarious wellness benefits covering fitness, mental health, and more\n\nDaily lunch and dinner in our office\n\nUnlimited compute budget subject to ROI justification\n\nUnlimited Codex and Claude credits\n\nTravel\n\nHow we're different\nBuild believes in the Bitter Lesson. By taking a general approach of learning from humans, our addressable market is all physical labor.\nWe 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.\nBuild AI is an equal opportunity employer. We review every application. If you do not meet every bullet, still apply.
