Building Engineer

About M5 Services M5 Services is a commercial facilities services company based in Pleasanton, CA. We keep commercial buildings running for property managers, owners, and tenants across the Bay Area and Sacramento through five core services: Building Engineering, Facility Solutions, Special Projects, Janitorial, and Property Assessment. We're a tight, ~25-person team that values people who take ownership, communicate clearly, and take pride in a building that runs right. The Role As a Building Engineer, you are the hands-on technical presence at our clients' properties. You'll operate, maintain, troubleshoot, and repair the mechanical, electrical, and plumbing systems that keep commercial buildings safe and comfortable. Some days you're on a preventive maintenance route; other days you're diagnosing a rooftop unit that quit at 2 p.m. on the hottest day of the year. You'll work directly with property managers and tenants, so you're as much a relationship person as a technician.
