Job summary

Giga Energy Inc. is seeking a BIM Modeler, Mechanical to develop and coordinate mechanical systems models in Revit for data center and industrial projects. You will work with multidisciplinary teams to maintain one federated model from design through fabrication and field support.

The role emphasizes practical engineering judgment, on-site collaboration in Houston, and close coordination with electrical and structural disciplines under an in-office culture.

Qualifications

• Bachelor's degree in Mechanical Engineering, Architectural Engineering, or related field, or equivalent experience.
• 5+ years of experience with Autodesk Revit for mechanical systems.
• Strong experience modeling HVAC ductwork, hydronic piping, and equipment layouts.
• Knowledge of duct sizing, airflow, velocity, and pressure-drop criteria.
• Ability to take engineering markups and develop complete mechanical layouts independently.
• Experience coordinating mechanical systems across disciplines and resolving BIM clashes.
• Attention to detail and clear communication.

Responsibilities

• Develop mechanical system models in Revit from markups and design criteria.
• Size ductwork and piping based on airflow, velocity, and equipment needs.
• Produce mechanical plans, sections, details, and schedules from BIM models.
• Coordinate mechanical systems with structural, architectural, electrical, plumbing, and controls.
• Run Navisworks clash detection and drive resolutions.
• Track coordination issues through closure and ensure changes are incorporated.
• Maintain model accuracy and compliance with BIM standards.
• Support construction teams by resolving routing questions and field conditions.
• Perform quality-control reviews to catch errors before release.

Job description

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
