  • Conduct coaching, retraining, and remediation to address performance gaps and recurring quality issues.
  • Partner with QA and tooling teams to identify bottlenecks and improve annotation workflows and processes.
  • Identify high-performing team members and support their development toward future leadership responsibilities.
  • Track project progress, identify operational risks and blockers, and communicate updates to the Project Lead.
  • Maintain consistent annotation quality and operational efficiency in a fast-paced environment with tight deadlines.

Requirements

  • 4–6 years of overall professional experience, including at least 2 years in a team leadership or supervisory role.
  • Proven experience managing teams against productivity, quality, and delivery targets.
  • Strong organizational, communication, problem-solving, and decision-making skills.
  • Ability to interpret complex guidelines and convert them into clear instructions and workflows.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
