Giga Energy Inc.
Giga is building gigawatts of AI data centers to hasten a future of intelligence and abundance. We build data centers fast and at scale by combining the capabilities of an equipment supplier, engineering firm, general contractor, and real estate developer under one roof. Our team moves quickly and thinks practically. If you're ready to make an impact in an industry that matters, we're looking for people like you. The Pace: We're building at a speed most companies talk about but never actually operate at. If you've been bored somewhere else, you won't be here. The Impact : Every person at Giga touches the work that matters. No layers, no waiting for approval chains. You'll see your fingerprints on what we ship. The Team: A team of operators defining the future of AI infrastructure. We recruit A-players from the most innovative companies in the world, and they choose Giga because the work here means more. The Moment : AI doesn't run without power, and that's us. Giga is the picks and shovels behind the AI revolution. This industry is about to explode, and you'll be in the room where it's already happening. What you’ll do The Category Buyer for the Transformers category owns the end-to-end buy for everything that goes into a transformer — metal tanks, core & coil, dielectric oil, and final assembly components. You will run supplier sourcing and negotiations, place and manage purchase orders to keep production on schedule, and build the category strategy that drives cost down and delivery performance up over time. This role is central to keeping our transformer line fed with the right materials, at the right cost, on time. Where you’ll work We are an in-office culture — velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is ideally based in our Houston plant location, with full-time onsite expectations outside of bi-weekly WFH Fridays. Responsibilities Order Execution & Delivery Place and manage purchase orders for metal tanks, core & coil, dielectric oil, and transformer assembly components to maintain tight delivery timelines Track open orders and supplier commitments; expedite as needed to prevent production line disruptions Own on-time delivery performance for the transformer category and drive corrective action when suppliers miss commitments Sourcing & Negotiation Run the RFI/RFQ process for new and existing components — metal tanks, core & coil (electrical steel, copper/aluminum winding), oil, and assembly hardware Negotiate component costs, payment terms, and supplier contracts to meet category cost targets Identify, qualify, and onboard new suppliers to strengthen the transformer supply base, including tank fabricators and core & coil winders Draft and manage supplier contracts, including terms, pricing schedules, and volume commitments Manage risk on long lead-time items — core steel, copper/aluminum winding, and custom-fabricated tanks — through buffer strategies, alternate sourcing, and early-warning tracking Monitor supply base health and flag single-source or capacity risks before they impact production Partner with Quality and Engineering on supplier qualification and material substitutions when risk requires it Commodity Strategy & Performance Build and maintain the commodity strategy for the transformer category — sourcing roadmap, supplier consolidation, and cost-down initiatives Track and report supplier performance: on-time delivery, quality, cost, and responsiveness Drive year-over-year cost reduction through negotiation, should-cost analysis, and supplier competition Stay current on steel, copper, aluminum, and transformer oil market pricing trends to inform buying and negotiation timing Requirements 5+ years in procurement, sourcing, or commodity management, ideally in transformer, electrical equipment, or heavy industrial manufacturing Experience buying core & coil materials (electrical steel, magnet wire), metal tanks/fabrications, or dielectric fluids a strong plus Hands-on experience running RFI/RFQ processes, negotiating supplier contracts, and issuing/managing POs Track record of managing long lead-time and supply-constrained categories Strong negotiation skills with a track record of delivering measurable cost reduction Comfortable working with ERP/procurement systems for PO management and reporting Ability to read BOMs and component specifications to support sourcing decisions Strong written and verbal communication; able to work cross-functionally with Engineering, Quality, and Operations Experience in transformer or switchboard manufacturing, familiarity with electrical infrastructure Experience with ERP/MRP systems (SAP, Oracle, Dynamics365, NetSuite, etc.) Experience with establishing a vendor network from the ground up How We Work We value people who take ownership, raise risks early, communicate directly, and follow through. Incomplete information is part of the job. Make the best decision you can, document it, and adjust as the facts change. Move quickly on reversible decisions and take more care when security, safety, financial, employee, or customer risk is involved.
