Sourcing Manager V # 26-24631

US Tech Solutions • New York, NY

17h • 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.
