Centaur

About Centaur AI Centaur.ai provides data annotation and datasets with a quality-driven workforce management system for teams building mission-critical AI, primarily in healthcare. We engineer accuracy from the start by harnessing collective intelligence, in which multiple experts compete, are benchmarked, ranked, and proven, so that a stronger signal consistently outperforms any single annotator. This delivers superhuman annotation at scale across text, image, video, 3D, audio, waveform, and emerging modalities. Built for domains where precision is non-negotiable, Centaur powers AI that can be trusted in production. Researchers and industry leaders choose Centaur because we make quality inevitable, not aspirational. Centaur is backed by leading investors, including Y Combinator, Accel, and Matrix, and closed a Series B led by SignalFire in late 2024.

(Internally we call this Supply Lead) About Centaur Labs Centaur Labs is the modern data labeling solution driving AI innovation across the healthcare industry. From agile startups and cutting-edge research labs to global pharmaceutical giants and Big Tech, we empower the entire spectrum of AI. Our expert crowd of 50k+ labelers, combined with our gamified DiagnosUs app for motivation and quality control, ensures scalable, high-quality labels are delivered in as little as 24 hours. We are backed by leading investors including Y Combinator, Matrix, and Accel, and recently closed a Series B led by SignalFire. About the role The Supply team keeps a scalable, healthy network of labelers flowing into every Centaur project. As Supply Lead, you own the entire labeler lifecycle - sourcing, contracting, onboarding, paying, supporting, and engaging - across both our app-based labeler community and our network of specialists. Labelers are the single biggest variable in project quality, which makes Supply one of the highest-impact functions in the company. Day-to-day, you make sure every project is staffed with the right people, at the right rate, on time. This is an AI-native role by design. You'll work alongside systems that surface spend and quality dashboards in real time, track channel performance, and maintain the labeler taxonomy. Your job is to decide where the business goes - labeler payment rates, supply mix, fraud strategy, channel investment - and to push the systems harder where they aren't pulling their weight. The person who thrives here redesigns systems rather than runs them. The unit economics of how every project gets staffed run through this role. You'll own the rate card, the partner mix, the labeler database, and the labeler experience - and you'll see the impact in our margin within your first quarter. Responsibilities Own sourcing strategy and cost. Set pricing rate cards, negotiate partner agreements, and define the supply mix across channels.  Own contracting. Maintain SOW and contract templates for independent and partner-staffed labelers, plus the security standards we apply to each project. Work directly with outside legal counsel on partner negotiations and contract changes. Own trust and fraud. Run the identity verification, credentialing, and fraud-detection programs that protect both our specialist network and our app-based labeler community. The bad actors evolve with the industry; staying ahead is permanent. Own payments and offboarding. Run the payments cadence across our external payment tools, the offboarding workflow, and the controls that keep payments accurate, on time, and audit-ready. Own labeler experience. Set the frameworks for how labelers are supported on every project - the documentation, the tooling (Intercom), and the KPIs that make sure labelers feel heard and respected. Represent the voice of the labeler to leadership. Own the labeler database and taxonomy. Decide the structure, definitions, and when they change. A well-structured database is what makes independent-labeler-first viable. Manage the Supply team. Lead an agile team, run the cadence (weekly, biweekly metrics review, quarterly planning), and report Supply's KPIs to leadership. First 90 days By the end of your first quarter we'd expect real progress on four fronts: an audit of labeler spend with a recommendation on how to bring costs down; a deep dive with Product on how to scale our vetting and credentialing framework; stabilizing the new support workflow; and a plan to prioritize direct sourcing channels so we rely less on staffing partners. You may be a good fit if you Have 8-10+ years of operational experience, ideally at a labeling, annotation, or crowdsourcing company - or have run a sourcing/staffing network in clinical staffing, an online contractor marketplace, or healthcare contracting Are AI-native. When you see a recurring decision - matching labelers, screening for fraud, pricing a request - your instinct is to

About Centaur Labs Centaur Labs is the modern data labeling solution driving AI innovation across the healthcare industry. From agile startups and cutting-edge research labs to global pharmaceutical giants and Big Tech, we empower the entire spectrum of AI. Our expert crowd of 50k+ labelers, combined with our gamified DiagnosUs app for motivation and quality control, ensures scalable, high-quality labels are delivered in as little as 24 hours. We are backed by leading investors including Y Combinator, Matrix, and Accel, and recently closed a Series B led by SignalFire. About the role This role sits on the Supply team. Supply ensures every Centaur project is staffed with high-quality labelers, at competitive/market rates, fast enough to hit kickoff. We own the labeler experience end-to-end so the best people keep coming back.  Every specialist who annotates with Centaur goes through this role. You'll run sourcing from the moment a request lands to the moment specialists are ready to work. You manage vetting, contracting, and onboarding throughout the process. You'll also build the pipeline that makes future sourcing faster: partnerships with hospitals and professional communities, recruiting campaigns, and maintaining a cleaner, better-tagged database. This is an AI-native role. You'll work alongside systems that draft sourcing requests from SOWs, propose shortlists, run first-pass vetting, and flag suspicious applicants. Your job is to be sharper than those systems where it counts and push them harder where they aren't pulling their weight. Some of those systems exist today. Some are partial. Some we'll build with you. The person who thrives here wants to tune the system, not be the system. We're shifting from staffing-partner-dependent to independent-specialist-first. That shift runs through this role. You'll own the database, the partner mix, and the unit economics of how every project gets staffed - and you'll see the impact in our margin and our speed within your first quarter. Responsibilities Run sourcing end-to-end. Translate customer SOWs into specialist profiles, build shortlists, and push independent specialists first when viable. Own partner coordination. Be the day-to-day point of contact for our staffing partners during sourcing,onboarding, and offboarding. Send requests, field replies, and close every loop before kickoff. Run vetting and credentialing. Catch scammers, verify credentials, and credential against SOW spec before kickoff. Execute contracts. Send SOWs and labeler contracts, track signatures, and escalate when issues arise. Approve payment runs. Approve weekly runs, double-check the numbers, and triage payment issues with partners. Hunt for the next 1,000 specialists. Stand up partnerships with hospitals, online communities, WhatsApp groups, and med-school networks. Design BAA and med-student campaigns with Marketing. Keep the database clean. Tag every new labeler against our taxonomy at intake and maintain trusted tags over time. You may be a good fit if you Have 3+ years in operational sourcing or talent operations - ideally at a labeling, annotation, staffing, or healthcare-contracting company Treat every manual step as a bug, and reach for automation before a manual checklist Are detail-obsessed - you catch sourcing errors, vetting gaps, payment mistakes, and contract typos before they scale Write clearly and calmly over email and Slack; most of this job runs through written partner and labeler communication Use AI tools as a core part of how you work, and would rather tune a workflow than do it twice Are comfortable with Series B pace - a new SOW can land Monday, source Tuesday, kick off Wednesday Strong candidates may also have Experience coordinating a contractor or contingent-worker network (clinical trial staffing, agency operations, HR tech) Light scripting or no-code automation experience (Retool, Zapier, Apps Script, or similar) Built or contributed to a Claude / Cowork skill, custom G
