Construction Manager

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 As Construction Manager on Giga's Project Development team, you will be at the center of building the physical infrastructure that powers the AI revolution. You'll lead and oversee all on-site labor operations for data center construction projects — from groundbreaking through  commissioning— ensuring work is delivered on schedule, within budget, and to the highest standards of quality. This is a high-visibility, high-impact role where your decisions move concrete and steel. You'll work directly with subcontractors, project owners, and internal stakeholders to keep projects on track and solve problems before they become delays. If you want a role where you can see — literally — the results of your work, this is it. 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 San Francisco, Long Beach, or Houston offices, with full-time onsite expectations outside of bi-weekly WFH Fridays. That said, we will make exceptions for truly exceptional talent if you live outside one of our hubs. If you're the right person for this role, we'll have a conversation about what works. Responsibilities Oversee and manage all on-site labor, subcontractors, and construction activities for data center build projects from mobilization through turnover. Develop and maintain detailed construction schedules, ensuring milestones are met and proactively identifying and mitigating schedule risks. Coordinate daily field operations including manpower planning, equipment logistics, and material delivery sequencing. Enforce and uphold safety standards on-site in alignment with HSE policies; act as a key partner to the HSE Manager to maintain a zero-incident culture. Participate in constructability reviews during the design phase to ensure alignment between design intent and field execution. Review and interpret construction drawings, specifications, and RFIs to ensure accurate field execution. Conduct daily site walks and weekly progress meetings with subcontractors and project stakeholders. Identify, document, and manage field change orders; coordinate with the project and Engineering teams on scope and cost impacts.
