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 As Fire Alarm Engineer at Giga, you will provide technical design leadership and expertise for fire alarm systems, detection systems, smoke control systems, and life safety systems across our AI data center facilities. You'll work on multiple concurrent projects, ensuring technical excellence, design quality, and code compliance while mentoring junior staff and collaborating closely with project teams, clients, and authorities having jurisdiction. This is a hands-on specialist role for someone who wants real technical ownership and thrives in fast-paced, collaborative environments. WHERE YOU'LL WORK This role is based in one of our offices (Houston, TX / Long Beach, CA / San Francisco, CA / Reno, NV) or fully remote. We work in person because the best engineering happens when smart people are in the same room. Some travel to active project sites and client meetings should be expected. 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.
