Buyer - Purchasing - Full Time

Giga Energy

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. The Pace: We're building at a speed most companies talk about but never actually operate at. You'll see your fingerprints on what we ship.
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.
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.
Order Execution & Delivery

Place and manage purchase orders for metal tanks, core & coil, dielectric oil, and transformer assembly components to maintain tight delivery timelines
Own on-time delivery performance for the transformer category and drive corrective action when suppliers miss commitments
Run the RFI/RFQ process for new and existing components — metal tanks, core & coil (electrical steel, copper/aluminum winding), oil, and assembly hardware
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
Risk Management

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
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
  • Comfortable working with ERP/procurement systems for PO management and reporting
  • able to work cross-functionally with Engineering, Quality, and Operations

Bonus Points

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
We value people who take ownership, raise risks early, communicate directly, and follow through. 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.
Subsidized health, dental, and vision insurance

  • Equity (options) in a rapidly growing startup
  • Healthcare and Dependent Care Flexible Spending Accounts (FSA) or Health Savings Account (HSA)
  • Opportunities to collaborate in person at periodic team and company on-sites

We do not discriminate based on race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other protected characteristic as outlined by federal, state, or local laws. Giga Energy complies with all applicable labor laws, including the California Fair Employment and Housing Act (FEHA) and other relevant state and federal regulations. We provide reasonable accommodations for qualified individuals with disabilities and encourage applicants who require accommodations during the hiring process to contact us.
