What you'll doAs Director of HSE, you'll build and own Giga's health, safety, and environmental function from the ground up-designing the systems, policies, and culture that keep our people safe across manufacturing facilities, construction sites, data center deployments, and after-sales field service operations. This is a hands-on leadership role with real influence: you'll sit at the intersection of operations, engineering, and compliance at a company scaling faster than almost anything in the infrastructure space. If you've spent your career in bureaucratic safety programs where nothing actually changes, this will feel different. You'll own the outcomes.
Where you'll workWe 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.

- Partner with project managers, superintendents, and operations leads to embed safety requirements into project planning, site mobilization, and day-to-day execution.

- Own relationships with regulatory agencies and manage all compliance filings, audits, permits, and environmental reporting obligations.
- Build and lead a small HSE team as the company scales; define team structure, hire, and develop talent.

- Experience managing HSE across fixed facilities (manufacturing, warehouses), field/construction environments, and customer-site field service operations simultaneously.
- Proven track record conducting incident investigations and driving systemic corrective actions that reduce recurrence.
- Strong written and verbal communication skills; ability to translate complex regulatory requirements into practical, actionable guidance for field teams.

Who we hireWe hire people who thrive in chaos and get sharper under pressure. You don't wait to be told what to do, you spot the gap and fill it. When there's work to be done, you do it. You make decisions with the information you have, move fast, and adjust along the way. We're not looking for perfect; we're looking for people who get things done.
