Buffer Com Jobs in Seattle, WA (NOW HIRING)

You will lead the team responsible for how we build, manage, and scale our most critical supplier relationships across machine infrastructure. This is a senior leadership role at the center of one of the most complex and consequential supply chains in the AI infrastructure industry — one where decisions made at the supplier level directly determine whether CoreWeave can deliver on its commitments to customers running some of the world's most demanding AI workloads.

You will lead two deeply interdependent functions: Technical Sourcing Management and Supplier Materials Management. On the sourcing side, your team owns the strategies that determine who CoreWeave buys from, on what terms, and at what risk — driving supplier selection, multi-sourcing decisions, technology roadmap alignment, RFQ and cost modeling, and the commercial execution of MSAs, SOWs, and long-term agreements. On the materials management side, your team owns the execution layer: OxM capacity management, Clear-to-Build tracking, allocation execution, shortage recovery, ODM sub-tier PO placement, forecast alignment, and NPI ramp readiness. You will move fluidly between both — setting strategy, building commercial frameworks, and then ensuring your team has the discipline and tools to deliver on the ground.

Team Leadership & Organizational Development

• Lead, coach, and develop a team of Technical Sourcing Managers and Supplier Materials Managers supporting IT infrastructure categories including GPU & CPU compute, storage, and networking
• Define team structure, role clarity, performance standards, and career development frameworks aligned to CoreWeave's growth stage
• Build and sustain a high-accountability culture — driving execution excellence while developing the next generation of supply chain leadership
• Partner with Talent Acquisition to recruit top talent and scale the team ahead of infrastructure demand

Supplier Strategy & Relationship Management

• Own CoreWeave's global supplier management strategy across IT infrastructure suppliers — ODMs, OEMs, NAND/DRAM manufacturers, networking vendors, and beyond
• Establish and maintain executive-level relationships with strategic suppliers, serving as an escalation path for commercial and operational disputes
• Lead the development and governance of long-term agreements (LTAs), preferred supplier frameworks, and supply assurance mechanisms for constrained components
• Drive continuous improvement in supplier scorecards, KPIs, and SBR/QBR cadences to maintain transparency and accountability across the supply base

Commercial Execution & Contracting

• Lead or directly negotiate complex multi-year supply agreements, including volume commitments, pricing mechanics, escrow structures, forfeiture provisions, and tariff passthrough clauses
• Partner with Legal to develop and refine master supply agreements, program letters, and commercial frameworks that protect CoreWeave's commercial interests
• Identify cost reduction and value creation opportunities across the supplier portfolio, including BOM optimization, payment terms, and strategic inventory positioning
• Manage commercial risk exposure across the supply base — including supplier financial health, single-source dependencies, and geopolitical risk

Supply Assurance & Materials Management

• Drive supply-demand alignment across IT infrastructure categories, partnering with Infrastructure Planning, Finance, and Engineering to translate build forecasts into procurement signals for the vendor base
• Oversee CTB (Clear-to-Build) tracking and materials management operations, ensuring the team maintains visibility into component availability, lead times, and supply risk for all critical BOM items
• Establish and maintain capacity reservation agreements and buffer stock strategies for long-lead, constrained components (GPUs, SSDs, DRAM, ASICs, optics, NICs)
• Lead escalation and resolution of supplier delivery disputes, quality events, and allocation shortfalls — maintaining CoreWeave's operational continuity

Cross-Functional Partnership & Executive Communication

• Serve as a senior supply chain voice in CoreWeave's infrastructure planning and capacity review processes, influencing program timelines and procurement strategy
• Present supply chain status, risk assessments, and strategic recommendations to senior leadership including C-suite and Board-level stakeholders
• Partner with the Data Center Engineering, Solutions Architecture, and Operations teams to ensure sourcing strategies align with technical standards and deployment requirements
• Collaborate with Supply Chain Analytics and Finance on supplier spend analytics, forecast accuracy, and working capital optimization

• 10+ years of progressive supply chain experience in enterprise hardware, data center infrastructure, or cloud/hyperscale environments
• Deep technical fluency across IT infrastructure hardware categories: GPU/CPU servers, NVMe SSDs and NAND flash technology, DRAM, high-speed networking (Ethernet and InfiniBand), optical transceivers (QSFP, OSFP), and switch platforms
• Demonstrated experience leading and developing teams of sourcing professionals, including Technical Sourcing Managers and/or Materials Managers
• Proven track record of independently negotiating and executing large-scale, multi-year supply agreements with ODMs, OEMs, and component manufacturers at the $100M+ level
• Strong command of commercial contract structures including LTAs, volume commitments, escrow mechanics, forfeiture triggers, price protection, and tariff passthrough provisions
• Expertise in supply-demand planning, CTB tracking, and materials management for complex multi-tier hardware BOMs
• Experience operating at executive level — presenting to and influencing C-suite stakeholders on supply strategy, risk, and program trade-offs
• Strong analytical foundation: ability to build and interpret financial models, spend analyses, and supply/demand plans in support of strategic decisions
• Proven ability to operate with urgency and rigor in a high-growth, fast-changing environment

• Experience in hyperscaler, cloud, or AI infrastructure environments (e.g., hyperscale ODM procurement, GPU infrastructure at scale)
• Familiarity with NAND flash market dynamics, including QLC/TLC architecture trade-offs, DWPD specifications, and enterprise SSD supplier landscape
• Working knowledge of data center networking topologies (spine-leaf, rail-optimized GPU fabric) and associated hardware procurement (NICs, switches, optics)
• Experience managing supplier relationships in global markets including APAC (Taiwan, Japan, South Korea, China) and navigating associated regulatory and logistics considerations
• Background in contract negotiation for constrained/allocation-managed components — GPU silicon, HBM, advanced packaging
• Familiarity with procurement tooling and workflows including NetSuite, Ironclad, or equivalent ERP/CLM platforms
• MBA or equivalent advanced degree a plus; not required
