BIM Designer, Mechanical

Location: Houston, TX. Remote, USA.

Department: Engineering

What youll do

As a BIM Designer, Mechanical, you’ll develop and coordinate mechanical systems models (ductwork, hydronic piping, and equipment layouts) across our AI data center and industrial construction portfolio. Youll translate engineering markups and design criteria into fully coordinated, constructible Revit models, applying real mechanical engineering judgment rather than just drafting what youre 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 youll work

We are an in-office culture — velocity matters when youre 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 youre the right person for this role, well 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 isnt 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 Gigas 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

• Bachelors 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
