Data Quality & Annotation Lead

Nimble is an AI robotics company building the autonomous supply chain to power fast, efficient and economical commerce. We’re training robot AGI to power a proprietary generalist supply chain superhumanoid, the first robot in the world capable of performing thousands of tasks across the supply chain. We’ve raised over $220M at over $1B valuation and formed a strategic alliance with FedEx to build a national network of autonomous warehouses capable of generating many billions in annual revenue. We are a hardcore and obsessed team of the world’s best engineers and operators. If you are obsessed with your craft, enjoy a high-intensity and fast moving high impact environment, are super high agency in getting hard things done and want to be part of building the world’s most legendary robotics company at the most pivotal moment in history, we want to work with you.

We are on a mission to empower and inspire mankind to accomplish legendary feats by inventing robots that liberate us from the menial. We will accomplish this by training robot AGI to invent and build the Autonomous Supply Chain – everything from the inside of factories and warehouses to your front door – powered by generalist superhumanoids.

Our founding team comes from the AI labs at Stanford and Carnegie Mellon and our board of directors include famed robotics and AI legends including Fei-Fei Li (Chief Scientist of AI at Google and Director of Stanford’s AI Lab), Marc Raibert (founder of Boston Dynamics), and Sebastian Thrun (founder of GoogleX, Waymo; Stanford Professor and considered the father of autonomous vehicles).

Let’s be legendary.

Nimble Brain turns real-world operational data into the training sets, evaluations, and feedback loops that make our robots smarter every day. The fuel for that engine is human demonstration data — skilled operators across our sites performing and recording the tasks our superhumanoids learn from — and the quality of every episode we collect sets the ceiling on every model we train.

We're looking for a Data Quality & Annotation Lead to become the first dedicated owner of that quality bar. Own the rubric, not just run it: you'll write the acceptance criteria that define what a "good" episode is for every task family, build the audit workflows that enforce them as we scale from ~15 to 100+ operators across four sites this year, and stand up the annotation engine — including a remote annotation team turning around episode review overnight — that keeps labeled, trusted data flowing to research on schedule.

This is a hands-on, metrics-driven, build-from-scratch role. You'll be based at our San Francisco HQ and spend heavy time at our collection sites, especially during operator ramps. Success looks like an episode acceptance rate that holds steady while the operator base grows 10x — with rubrics, audits, and dashboards that run like clockwork instead of heroics.

• Familiarity with imitation learning / robot learning data — what makes a demonstration usable for model training.
• Experience scaling annotation or rater teams: pods, shift leads, inter-rater reliability programs.
• Experience selecting and managing offshore annotation vendors, or standing up direct offshore teams (EOR, timezone-shifted workflows).
• Multi-site operations experience.
