Senior Hardware Buyer

Responsibilities

• Strategic sourcing & negotiation: Lead end-to-end negotiations with ODMs, OEMs, white-box suppliers, Tier-1 semiconductor and hardware vendors. You will secure volume discounts, favorable terms and conditions, and priority capacity allocation during market shortages.
• Supply chain resilience: Build a robust, diversified supplier network to mitigate geopolitical and logistical risks. In partnership with the Infrastructure team, you will develop contingency plans for critical components to ensure uninterrupted operations.
• Vendor relationship management: Move beyond transactional interactions to build deep, strategic partnerships at senior vendor level. You will act as the primary liaison between Proton's engineering needs and vendor roadmaps.
• Process optimization: Audit and overhaul existing procurement workflows. Implement data-driven models on cost, availability and quality to optimize purchasing efficiency and velocity.
• Cross-functional leadership: Collaborate closely with Engineering, Finance, and Legal teams to define hardware specifications, validate technical requirements, and ensure compliance with Proton's processes and strict security and privacy standards.
• We need you to have:
• Scale-up experience: Demonstrated success in scaling hardware procurement process and team for high-growth technology companies, managing orders ranging from $1M to $100M+.
• Negotiation mastery: A reputation for closing complex deals under pressure. You are comfortable challenging vendors on pricing and terms to achieve the best possible outcome for Proton.
• Data-driven decision making: Ability to analyze market trends, pricing indices, and inventory levels to make strategic proactive purchasing decisions.
• Strong ownership mindset: You treat every dollar spent as your own. You take full responsibility for procurement outcomes and do not accept "that's how it's always been done"
