Software Engineer, Scaling

Build AI•San Francisco, CA

5d•Onsite

About The Position

Build AI is hiring a software engineer to build the products used by on-the-ground scaling teams in factories and job sites. The role focuses on removing software obstacles to increasing data collection, including tasking, device health, local tooling, and site standup. The engineer will work closely with operations teams, observe where time is lost, ship improvements, and measure their effect on useful collection time. They will also make launching sites and countries repeatable, provide site-health visibility to field leads and San Francisco engineering, and connect field tools with data ingestion and marketplace incentives. Travel or embedding with field teams may be necessary to develop effective products. Build AI describes itself as a vertically integrated data hyperscaler for Physical AI, spanning hardware, manufacturing, logistics, data collection, and model training. The company is fully in-person in San Francisco (Financial District) and Shenzhen (Nanshan). Technical staff are expected to contribute to both engineering and research and work across disciplines as needed.

Requirements

Strong generalist software engineering skills and an interest in shipping products for operators, not only backend services.
Comfort working with messy real-world operations and building 0-to-1 tools.
Willingness to travel or work closely with field teams.
Measure success by whether scaling teams can scale more effectively, rather than by polished abstractions.

Nice To Haves

Experience embedded with field, operations, logistics, or deployment teams.
Experience standing up tools in new sites or countries.
Marketplace, incentives, or operations-product background.
Linux/Python experience and comfort debugging hardware-adjacent field issues.

Responsibilities

Build internal products for collection operations, including tasking, site standup, device inventory, shift tracking, and local tooling that works with poor connectivity.
Work alongside operations teams to identify where they lose time, ship software that removes those obstacles, and measure hours of useful collection per person.
Make standing up a new site or country a repeatable product rather than a custom process.
Produce site-health views showing what is recording, failing, or stuck in upload so field leads and San Francisco engineering share the same picture.
Work with data infrastructure and marketplace incentives so field tools connect to ingestion and pay.
Travel or embed with field teams when needed to get the product right.
Contribute to engineering and research and work across disciplines as needed.
