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've collected the largest dataset of physical labor in the world. We're scaling to 1B hours over the next two years, collecting data from 100M+ people worldwide. Software is how we get there.

How data collection works

We give wearable cameras to field teams and partners. Each day, they recruit workers, assign devices, pay workers to wear the cameras on the job, collect the devices/SD cards, and upload the footage. At scale, inefficiency, fraud, and human error emerge: devices and SD cards get lost or stolen, devices sit idle, and contributors produce poor-quality data.

What you'll own

Vendor platform: the Android and web app that coordinates our operators, partners, and vendors as they source, onboard, and pay contributors and businesses. That covers device assignment, attendance, collection tracking, payments, and fraud/loss prevention. Like Didi or Uber, but for data collection.

Partner growth: referral programs that grow the partner network, and models that forecast how much data existing and new partners can collect.

Data infrastructure: upload, storage, and processing pipelines that run at petabytes per month and grow 10× a year.

Data QA: orchestrate, train, and fine-tune models for a QA pipeline that catches bad data automatically.

Recruiting tools: software that speeds up hiring across the company.

Anything else that is blocking scale.

You'll work directly with the founders and the global ops team, and you'll own problems end to end, from spotting them through shipping the fix and supporting it.

Culture fit

You believe your life is wasted if you do not change the world in some non-trivial way.

You are excited to put everything into the company to do your life's work.

You love solving hard problems. The harder, the better.

You thrive with autonomy: spot problems, solve them, own the outcome.

Requirements

Have built and shipped software that real users depend on.

Comfortable across frontend, backend, APIs, and databases, and willing to learn whatever else the job needs.

Fluent in English and able to be based in Shenzhen full time.

Nice to have

Android app development.

Data pipelines, large file uploads, or ML/QA systems.

Can start immediately.

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.

Build AI is an equal opportunity employer. We review every application. If you do not meet every bullet, still apply. Questions: research@build.ai

Staying safe while you apply

Never pay to apply, interview or accept an offer. ROLIVA never asks you for payment to apply to a job.
Apply only through the official “Apply on the employer’s site” button, on the employer’s own site, and check that a recruiter’s email uses that employer’s own domain rather than a free email address.
Be cautious of an offer made with no real interview, or pressure to decide quickly or share financial details early.
