This is a highly visible role with significant ownership. You’ll independently lead negotiations ranging from tactical purchases to multi-million-dollar strategic agreements. Your work will directly influence how quickly Mercor can adopt new technologies, scale its AI platform and expert network, and build durable commercial advantages.

• Partner with stakeholders across Engineering, Security, Product, Finance, Legal, IT, and Operations to deliver commercial outcomes that enable the business to move quickly and scale efficiently.

• Structure commercial agreements that balance speed, flexibility, cost, and long-term business value.

• Independently negotiate agreements ranging from tactical purchases to $1M+ strategic vendor relationships.

• Own competitive sourcing events, pricing strategy, contract negotiations, renewals, and supplier relationships.

• Provide market insights and commercial guidance to influence vendor and investment decisions.

• Help build scalable procurement processes that enable growth without creating friction.

What We're Looking For

• 7+ years of experience in strategic sourcing, procurement, vendor management, or commercial negotiations.

• Proven experience negotiating complex software, SaaS, cloud, AI, infrastructure, or technology agreements, including $1M+ strategic deals.

• Strong commercial judgment with the ability to structure creative, win-win agreements.

• Exceptional stakeholder management skills and experience partnering with Engineering, Security, Product, Finance, and Legal teams.

• Strong analytical, financial, and negotiation skills.

• A builder’s mindset with the ability to thrive in a fast-paced, high-growth environment.
