Data Annotation Lead

We’re looking for a Data Annotation Lead to own our annotation operation end-to-end and build the team behind it. This is a lead / player-coach role with a heavy PM lean: you’ll set the framework, quality bar, and tooling for annotation, turn ambiguous research requests into crisp guidelines, and scale a workforce that can pivot fast without dropping quality. You’ll sit at the seam of ML/CV, product, and operations.

What you’ll do

• Own annotation operations end-to-end - quality, throughput, and cost per delivered hour
• Build and lead the in-house annotation team; own the in-house vs. partner/BPO mix and manage external vendors where used
• Translate research and client requirements into clear annotation guidelines, taxonomies, and QA rubrics
• Stand up the quality system: audits, inter-annotator agreement, golden sets, reviewer scorecards, escalation paths
• Partner with ML/CV and product to spec and pilot new annotation task types for fast-moving experiments
• Drive AI-assisted labeling (model pre-labels * human correction) to raise throughput and cut cost
• Own the metrics - dashboards on quality and volume - and report the state of annotation to leadership
• Stay in the weeds: annotate yourself whenever a new task type is being designed

• Direct experience in data annotation / labeling (required - the thing we care most about)
• Ideal background in data collection, physical AI / robotics, or text annotation
• Proven people and operations leadership - you’ve built or scaled a team or function
• PM instincts: ruthless prioritization of competing requests, organized execution under ambiguity, strong stakeholder management across annotators, engineering, and clients
• Clear written and verbal communication - your guidelines are the source of truth for the team
• Comfort with annotation tooling and the ability to leverage AI coding tools to build internal trackers/dashboards (no formal CS background required)
• Intermediate understanding of ML and how annotation quality drives model performance
• A level of hardcore-ness while still treating people like people

Nice to have

• Previously led a data annotation team, or were a top-tier annotator yourself
• Vendor / BPO management experience, ideally where quality was the primary lever
• Familiarity with text annotation styles and video concepts (frame rate, keypoints, bounding boxes, temporal segments)
• Experience managing distributed or offshore teams
