Note: The job is a remote job and is open to candidates in USA. Giga is building AI data centers by combining equipment supply, engineering, construction, and real estate development capabilities. The BIM Modeler, Mechanical will develop and coordinate mechanical systems models in Revit, produce coordinated construction documentation, resolve clashes, and support construction and field teams across AI data center and industrial projects.

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

Skills

• 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
• 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, where applicable
• Opportunities to collaborate in person at periodic team and company on-sites
