US Tech Solutions•New York, NY
•Hybrid

About The Position

We work with a global network of vendors who supply human-annotated data supporting our AI research and product development. We're looking for a highly organized sourcing and program professional to support vendor onboarding and contracting execution. You'll be the connective tissue between our sourcing managers, business partners, and vendors - moving each engagement from selection through to a signed contract and a live program, and supporting ongoing supplier management and compliance once that program is live.

Requirements

  • Demonstrated success negotiating complex contracts and managing vendor relationships
  • Strong commercial negotiation skills across multiple levers beyond rates (volume discounts, quality thresholds, speed to quality, service levels)
  • Program management experience with business stakeholders, cross-functional groups, and third parties
  • Highly organized structured thinker; able to synthesize complex information into executive-ready summaries
  • BS/BA degree
  • 5-7+ years of outsourcing or strategic sourcing experience, ideally in tech or AI domains

Nice To Haves

  • Experience sourcing annotations for ML/AI or large language model development
  • Experience managing high-volume data annotation sourcing programs
  • Experience working with BPOs, crowdsource/freelance platforms, and boutique data vendors
  • Experience breaking down vendor cost models and understanding ROI drivers

Responsibilities

  • Drive new annotation vendors through the end-to-end onboarding process — intake, reviews, contracting, systems and payment setup, kickoff.
  • Support contracting and commercial workstreams: prepare documents, track rate cards and terms, manage amendments and renewals alongside Legal and Finance.
  • Keep multiple vendor onboardings moving in parallel, unblock stalled approvals, and maintain clear status reporting.
  • Partner with sourcing managers on vendor performance, governance, and business reviews.
  • Synthesize vendor and program information into clean, executive-ready summaries.
