• Review and adjudication workflows, designed with the quality team.
• Instrumentation that makes throughput and quality visible in real time.
• Weekly improvements, each measured to see whether it helped.
• An experience that stays fast and clear for people doing demanding work.

What you bring

• Three or more years of full‑stack engineering with React or a comparable framework and a typed backend.
• Product sense: you’ve shipped interfaces real users relied on.
• Relational data modelling and background jobs.
• You talk to users and change your mind.

Helpful, not required

• Workflow or annotation tooling.
• Marketplaces or two‑sided platforms.
