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 a software engineer to build the products the on-the-ground scaling teams live in. Your users are the people standing up collection in factories and job sites. If a site cannot collect more tomorrow because the software is in the way - tasking, device health, local tooling, site standup - that is on you.\nKey Responsibilities\nBuild internal products for collection ops: tasking, site standup, device inventory, shift tracking, and local tooling that works with bad connectivity\n\nSit with ops and watch where they lose hours; ship software that removes it, then measure hours of useful collection per person\n\nMake standing up a new site or country a repeatable product, not a custom process each time\n\nProduce site-health views: what’s recording, what’s failing, what’s stuck in upload - so field leads and SF engineering share one picture\n\nWork with data infrastructure and marketplace incentives so field tools connect to ingest and pay\n\nTravel or embed with field teams when that is what it takes to get the product right\n\nYou may be a good fit if you have (Must-have qualifications)\nStrong generalist software engineer who likes shipping product for operators, not only backend services\n\nComfortable with messy real-world ops and 0→1 tools\n\nFine traveling or working closely with field teams\n\nYou measure success in whether scaling teams scale harder, not in polished abstractions\n\nStrong candidates may also have experience with (Nice-to-have qualifications)\nTime spent embedded with field, ops, logistics, or deployment teams\n\nExperience standing up tools in new sites or countries\n\nMarketplace, incentive, or ops-product background\n\nLinux/Python and comfort debugging hardware-adjacent field issues\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.
