About Build AI
Build AI is the data hyperscaler for Physical AI. 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.
Job Summary
We’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.
Key Responsibilities
Build internal products for collection ops: tasking, site standup, device inventory, shift tracking, and local tooling that works with bad connectivity
Sit with ops and watch where they lose hours; ship software that removes it, then measure hours of useful collection per person
Make standing up a new site or country a repeatable product, not a custom process each time
Produce site-health views: what’s recording, what’s failing, what’s stuck in upload - so field leads and SF engineering share one picture
Work with data infrastructure and marketplace incentives so field tools connect to ingest and pay
Travel or embed with field teams when that is what it takes to get the product right
You may be a good fit if you have (Must-have qualifications)
Strong generalist software engineer who likes shipping product for operators, not only backend services
Comfortable with messy real-world ops and 0→1 tools
Fine traveling or working closely with field teams
You measure success in whether scaling teams scale harder, not in polished abstractions
Strong candidates may also have experience with (Nice-to-have qualifications)
Time spent embedded with field, ops, logistics, or deployment teams
Experience standing up tools in new sites or countries
Marketplace, incentive, or ops-product background
Linux/Python and comfort debugging hardware-adjacent field issues

How we're different
Build believes in the Bitter Lesson. By taking a general approach of learning from humans, our addressable market is all physical labor.
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.
