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 someone to make it incredibly easy to see the dataset, collection, quality, and evals. You will build the analysis and visualization layer — from capture through slices, examples, and live pipeline health — so people look at the data instead of dumping to a notebook. If someone has to wait on you for a plot, the product is not done.

Key Responsibilities

Design and ship a visualization suite: data collection, processing, analysis, and UI (web and/or CLI) for the dataset and the data engine

Make looking at examples, batches, coverage, quality, and failures fast enough that research and ops actually do it

Build views for collection health, taxonomy coverage, and eval results, wired to live pipelines rather than one-off dashboards

Work with Head of Dataset & Quality, Evals Lead, research, and ops on what must be visible to make a decision

Treat viz as a product: latency, defaults, shareability, and a bar for how we look at video and pose

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

Strong software engineer with a track record of data viz, internal tools, or product UI on heavy data

You care about making other people faster, not only about a pretty demo

Comfortable with large media — video, pose, or similar

Fine in a 0→1 environment where “everything” is still being defined

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

WebGL, custom renderers, or high-performance browser viz

You have shipped internal tools that other teams live in

Experience building analysis UIs (timelines, slice explorers, statistical summaries)

Python plus TypeScript/React

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
