About the role

Key responsibilities & impact

Own the vendor onboarding process end to end through a tiered supplier model.
Run intake triage for new supplier requests, assign tiers, drive diligence to completion, and keep the pipeline moving.
Maintain a single source of truth for infrastructure and compute contracts, including terms, renewals, spend, capacity, pricing, and termination rights.
Run renewals using a forward calendar and recommend renewal, renegotiation, or exit based on usage data.
Ensure compliance requirements flow into commercial terms during negotiations.
Track consumption against commitments and flag under-utilization or overage risks.
Define and report vendor KPIs and SLAs, including reservation allocation, incident frequency, provisioning lead times, support responsiveness, and invoice accuracy.
Run monthly or quarterly vendor reviews and executive QBRs for strategic partners.
Own escalation and remediation for vendor underperformance, including corrective action plans and service credits.
Establish vendor incident notification requirements and playbooks.
Maintain vendor scorecards for Infrastructure leadership and the executive team.
Own third-party risk assessment and periodic reassessment across security, data protection, financial, geographic, and concentration risks.
Keep certifications, insurance, and data-protection documentation current and support audits with retrievable vendor records.
Maintain continuity and exit plans for critical single-source dependencies.
Establish vendor management best practices and continuously improve processes, templates, and documentation through lessons-learned workshops.

Requirements

What you’ll need

BSc in Business, Supply Chain, Engineering, or a related field, or equivalent practical experience.
5+ years in vendor management, IT procurement, strategic sourcing, or supplier operations, with meaningful time spent on technology and infrastructure categories.
Demonstrated experience managing infrastructure and compute suppliers, such as GPU providers, OEMs, networking or storage vendors.
Proven track record negotiating and managing complex technology contracts, including MSAs, SOWs, DPAs, SLAs, and multi-year committed-spend agreements.
Fluency with the commercial mechanics of compute: committed use and reserved capacity, rate cards, burst and overage pricing, egress and transfer costs, SLA credit structures, renewal escalators, and liability caps.
Sufficient technical literacy to hold a credible conversation with infrastructure engineers about GPU, networking, and storage, and to distinguish a genuine capacity constraint from a negotiating position.
Experience designing and operating vendor governance frameworks — tiering, onboarding, due diligence, performance scorecards, and third-party risk assessment.
Excellent interpersonal and communication skills, with a track record interfacing with various types of stakeholders (engineering/operations teams, vendors, legal, finance) and writing clear deliverables.
Comfortable working in fast-moving, high-complexity technical environments, and building process where none currently exists.
Prior work experience in HPC, hyperscale, Telco, or AI infrastructure environments involving large-scale compute procurement.
Working knowledge of the GPU and AI hardware vendor landscape (NVIDIA and its OEM channel, alternative accelerator vendors, neocloud providers) and how their allocation models and roadmaps work in practice.
Understanding of datacenter commercial models, including colocation agreements, power contracts, and capacity reservation structures.
Familiarity with vendor management or contract lifecycle management (CLM) tooling, and with procurement workflows in ERP systems.
Exposure to export controls, sanctions screening, or hardware supply-chain constraints affecting GPU and networking availability.
Experience supporting SOC 2 or ISO 27001 audits from the third-party risk side.
A professional procurement or contract management qualification (CIPS, WorldCC, or equivalent).
