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.
