Description
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 a BIM Modeler, Mechanical, you’ll develop and coordinate mechanical systems models (ductwork, hydronic piping, and equipment layouts) across our AI data center and industrial construction portfolio. You'll translate engineering markups and design criteria into fully coordinated, constructible Revit models, applying real mechanical engineering judgment rather than just drafting what you're told. This role sits inside our growing BIM function, working shoulder-to-shoulder with electrical, structural, and civil designers to keep one federated model as the single source of truth from design through fabrication and field support.
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
- Develop mechanical system models in Revit from engineering markups, sketches, and design criteria, including ductwork, hydronic piping, and mechanical equipment layouts
- Size ductwork and piping based on airflow, velocity, pressure drop, and equipment requirements, applying sound engineering judgment when every detail isn't fully specified
- Produce mechanical plans, sections, details, and schedules directly from coordinated BIM models
- Proactively coordinate mechanical systems with structural, architectural, electrical, plumbing, and controls disciplines
- Run and participate in Navisworks clash detection, investigating root causes and driving resolutions rather than just flagging conflicts
- Track coordination issues through closure and ensure resolved changes are incorporated into the model
- Maintain model accuracy, organization, and compliance with Giga's BIM standards
- Support construction and field teams by resolving mechanical routing and coordination questions, incorporating field conditions into the model
- Perform quality-control reviews of mechanical models and drawings to catch errors and coordination gaps before release
Requirements
- Bachelor's degree in Mechanical Engineering, Architectural Engineering, or a related technical field, or equivalent experience
- 5+ years of experience developing mechanical systems in Autodesk Revit
- Strong experience modeling HVAC ductwork, hydronic piping systems, and mechanical equipment layouts
- Working knowledge of duct and pipe sizing, airflow, velocity, and pressure-drop criteria
- Demonstrated ability to take engineering markups and independently develop a complete mechanical layout
- Experience coordinating mechanical systems across architectural, structural, electrical, and plumbing disciplines, including identifying and resolving BIM clashes
- Strong attention to detail and clear written and verbal communication skills
Bonus points
- Experience designing mechanical systems for data centers, mission-critical, or other technically complex industrial facilities
- Familiarity with high-density data center cooling and liquid cooling infrastructure
- Experience with Navisworks Manage, Autodesk Construction Cloud / BIM 360, and clash detection workflows
- Familiarity with ASHRAE standards and mechanical codes
- Experience supporting projects through construction and resolving field coordination issues
Benefits
- Subsidized health, dental, and vision insurance
- Equity (options) in a rapidly growing startup
- 401(k) with 4% employer match
- Unlimited PTO
- Parental leave
- Healthcare and Dependent Care Flexible Spending Accounts (FSA) or Health Savings Account (HSA)
- Commuter benefits
- Team on-sites where all offices come in–person to collaborate
How We Work
We value people who take ownership, raise risks early, communicate directly, and follow through. Incomplete information is part of the job.

About this role
Giga Energy is scaling AI data center infrastructure at an unusual pace, and this BIM Modeler role sits at the center of that operation. You'd own the mechanical systems models—ductwork, hydronic piping, equipment layouts—that keep designs coordinated across electrical, structural, and civil disciplines. The work demands real engineering judgment: you're not just translating markups into Revit, but sizing systems based on airflow and pressure drop, running clash detection in Navisworks, and driving resolutions when disciplines conflict. You'll produce construction-ready plans and schedules directly from the model, then support field teams through completion.
The role requires five-plus years modeling HVAC and piping systems in Revit, a degree in mechanical or architectural engineering (or equivalent), and hands-on experience coordinating across multiple disciplines. Data center or mission-critical facility experience is a bonus. Giga emphasizes in-office work—Houston, San Francisco, or Long Beach with full-time onsite expectations except for bi-weekly work-from-home Fridays—though they'll consider exceptions for strong candidates elsewhere. The contract position includes standard startup benefits: equity, subsidized health coverage, 401(k) match, and unlimited PTO.
This suits someone who thrives on velocity and direct impact, wants to see their work shipped quickly, and can make sound decisions with incomplete information. If you've felt constrained by slower processes or approval chains elsewhere, the pace here is the draw.
