Vendor Manager

About This Role

Managing the company's relationships with its external suppliers is the core of this role, ensuring they meet commercial terms and perform as expected. The Vendor Manager will transform a fragmented supplier base into a governed, tiered portfolio that delivery teams can rely on, directly impacting the strength of the company's AI infrastructure platform.

Responsibilities

• Own the vendor onboarding process end to end, guiding new suppliers through a tiered model that matches diligence depth to relationship depth
• Run intake triage for new supplier requests: assign the right tier, drive diligence to completion, and keep the pipeline moving
• Maintain a single source of truth for every infrastructure and compute contract, including terms, renewal and notice dates, committed spend, reserved capacity, price escalators, and termination rights
• Run renewals on a forward calendar, flagging material renewals ahead of their notice window with recommendations to renew, renegotiate, or exit, backed by usage data
• Ensure compliance requirements flow into commercial terms before and during negotiations
• Track consumption against commitments and flag under-utilised reservations or approaching overage before they hit the budget, feeding real usage patterns back into the next negotiation
• Define and report the KPIs and SLAs that matter, such as allocation against reservation, incident frequency, provisioning lead times, support responsiveness, and invoice accuracy
• Run the vendor review cadence: monthly or quarterly reviews for partners, and QBRs with executive attendance for strategic partners
• Own escalation and remediation when a vendor underperforms: raise it, document it, agree a corrective action plan, and pursue service credits where earned
• Establish vendor incident notification requirements and playbooks (timeframe, escalation, documentation) for breach response and incident communication
• Maintain a vendor scorecard that Infrastructure leadership can read in five minutes and take to the executive team
• Own third-party risk assessment and periodic re-assessment across security, data protection, financial, and geographic areas
