About this role
About Giga
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.
Why join Giga
- 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 Materials Manager for Transformers owns the flow of materials behind our transformer production — metal tanks, core & coil, dielectric oil, and assembly components — from BOM accuracy and demand planning through to materials staged and ready to build. You will manage materials planning and scheduling across our transformer contract manufacturers, keep production supplied against manufacturing capacity, and manage the risk, lead time, and tariff exposure of a global transformer supply base. This role is the connective tissue between Procurement, Production, Engineering, and our contract manufacturers.
Where you'll work
This role is based out of our Houston location and will require 25% travel.
Responsibilities
BOM & Materials Planning
- Own BOM accuracy and structure for transformer products — tanks, core & coil, oil, and assembly hardware — in the ERP/MRP system
- Translate the production schedule into materials requirements (MRP); convert demand into supplier releases and purchase requisitions
- Manage engineering change (ECO) impact on existing transformer inventory and open orders
- Support New Product Introduction (NPI) — ensure long-lead components (core steel, copper/aluminum winding, tanks) are ordered early enough to hit pilot build and factory acceptance test (FAT) dates
Scheduling & Capacity
- Build and maintain the master production schedule (MPS) for the transformer line, reconciled against real contract manufacturer capacity
- Coordinate build schedules with tank fabricators, core & coil winders, and final assembly contract manufacturers
- Participate in S&OP/demand planning to align transformer production plans with sales forecasts
Inventory & Stock Management
- Own inventory strategy — safety stock levels, buffer stock, and build-to-order vs. build-to-stock decisions for tanks, core & coil materials, and oil
- Manage kitting and staging so the right components are ready at transformer build and final assembly stations
- Track inventory health: turns, excess & obsolete (E&O) inventory, and cycle count accuracy
Lead Time & Risk Management
- Manage lead times and allocation for long-lead transformer items — core steel, copper/aluminum winding, custom-fabricated tanks, and dielectric oil
- Make allocation calls during component shortages, balancing customer commitments and production priorities
- Identify and mitigate single-source, capacity, and geopolitical risk across the transformer supply base
Global Planning & Tariff Management
- Coordinate materials flow and inventory visibility across transformer contract manufacturers and Giga facilities
- Own tariff and trade compliance planning for transformer components — HTS classification, Section 301/232 exposure, USMCA qualification, and country-of-origin tracking
- Evaluate sourcing and inventory strategies (e.g., bonded warehousing, duty drawback) to manage tariff cost impact
- Manage logistics and expediting decisions — air vs. ocean freight — when schedules are at risk
Requirements
- 4+ years in materials management, production planning, or supply chain, ideally in transformer, electrical equipment, or heavy industrial manufacturing
- Hands-on experience with BOM management, MRP/ERP systems, and master scheduling
- Experience managing long lead-time materials — core steel, magnet wire, custom tank fabrication — in a transformer or similar heavy electrical equipment environment
- Working knowledge of tariff classification and trade compliance (Section 301/232, USMCA, HTS)
- Experience coordinating materials across multiple sites, including offshore contract manufacturers
- Strong analytical skills — comfortable building inventory, capacity, and risk models
- Ability to read BOMs, drawings, and specifications to support planning decisions
- Strong communication skills; able to work cross-functionally with Procurement, Engineering, Quality, and Operations
Benefits
- Subsidized health, dental, and vision insurance
- Equity (options) in a rapidly growing startup
- 401(k) with 4% employer match
- Unlimited PTO
- Parental leave
- Healthcare and Dependent Care Flexible Spending Accounts (FSA) or Health Savings Account (HSA)
- Commuter benefits
- Team on-sites where all offices come in–person to collaborate
