Product & Research Operations Manager, Human Data

The Role

We are looking for a Product and Research Operations Manager to design, scale, and operate Cartesia's global scaled evaluation workforce. This role sits at the intersection of product operations, data operations, and vendor management, and directly impacts model quality and customer outcomes. You will own the end-to-end workforce system: hiring pipelines, vendor strategy, workforce planning, quality control, and operational performance.

You are building a production system of humans-in-the-loop for AI, translating ambiguous product needs into operational workflows and partnering across product, engineering, data, and customer-facing teams to support real-world evaluation at scale.

Your Impact

• Design and implement workforce structure across languages, skill tiers, and use cases, including evaluators, auditors, and leads for TTS products

• Build capacity models to support continuous eval pipelines and data production workflows

• Own relationships with vendors such as data annotation firms and contractor platforms, negotiating rate cards, SLAs, and throughput guarantees

• Decide on build, buy, or hybrid workforce models and continuously benchmark cost and performance across regions

• Design multi-layer QA systems spanning self-checks, peer review, audits, and gold tasks

• Define and track inter-rater reliability, error rates by category, and annotator-level performance distributions

• Build escalation and retraining workflows to maintain quality at scale

• Run day-to-day operations including task allocation, throughput tracking, and SLA adherence

• Build systems to reduce evaluator fatigue, rotate task types, and maintain consistency across large-scale evaluations

• Partner with tooling teams to improve evaluator UX and with data teams to ensure clean, structured outputs for model training

What You Bring

• 6+ years in operations, workforce management, or data annotation systems

• Experience managing large contractor or vendor-based workforces

• Proven ability to scale operations from zero to production

• Systems thinking with the ability to design scalable operational frameworks

• Strong analytical skills with comfort around metrics like inter-rater reliability, precision, and throughput

• Ability to execute quickly under ambiguity with close attention to quality and edge cases

Nice to Have

• Experience in AI/ML data operations or evaluation pipelines

• Background in audio, speech, or language-related workflows

• Familiarity with QA systems and annotation tooling

• Experience with marketplace platforms such as Upwork or Mercor

• Exposure to multilingual operations
