Software Engineer, Generalist

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 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.

Key Responsibilities

Detect the highest-leverage gap that week — ingest, APIs, orchestration, field tools, hardware glue — and ship production-quality code for it

Build backend services and APIs for the data platform and the customer-facing product

Write processing and validation pipelines for incoming in-the-wild datasets

Script integrations between collection devices, cloud infrastructure, and software services

Design interfaces and developer workflows that the rest of the company actually uses

Work cross-functionally with research, Shenzhen hardware, and ops without waiting for a spec

You may be a good fit if you have (Must-have qualifications)

Strong full-stack skills; fluency in Python and at least one of TypeScript, React, Go, or C++

1–5+ years shipping software end to end, ideally in a 0→1 or startup environment

You ramp quickly in unfamiliar codebases and problem domains

Bias toward action and comfort with incomplete information

Experience shipping where the role was not clearly defined

Strong candidates may also have experience with (Nice-to-have qualifications)

Experience across backend, frontend, data, infra, and scripting

Hardware-adjacent, AI, or large-scale data systems

Prior startup experience during hypergrowth

Infrastructure or DevOps (Linux, containers, cloud)

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: [email protected]
