Job Description

OpenAI's data center construction teams work with engineering, supply chain, safety, quality, commissioning and operations partners to deliver the infrastructure that supports our computing needs.

Key Responsibilities

As a Mechanical Lead, you will lead mechanical field delivery for data center construction, including cooling infrastructure, mechanical yards, piping and data hall fit-out. You will oversee general contractors, specialist installers and service providers, combining practical mechanical expertise with hands-on field leadership. Your focus will be safe installation, contractor performance, coordinated interfaces and complete evidence for commissioning and operational handover.
Manage mechanical contractors, equipment and piping installers, and general-contractor interfaces against approved scope, schedule and quality requirements.
Oversee installation readiness and delivery of cooling plant, pumps, heat rejection equipment, air handling, piping and applicable liquid-cooling infrastructure.
Coordinate equipment placement, pipe routing, supports, access and maintainability with structural, electrical, controls and hardware teams.
Review contractor work plans, constructability, submittals, RFIs and change proposals; resolve field issues with the responsible engineering teams.
Oversee pressure testing, flushing, cleaning and inspection records; verify completion, defect closure and commissioning readiness.
Support commissioning specialists with mechanical startup and system tests, corrective work and complete as-built, operating and maintenance documentation.
Set contractor priorities, review staffing and progress, identify constraints early and coordinate recovery actions with construction leadership.
Maintain clear progress, risk and change reporting, with accountable handoffs between construction partners and OpenAI teams.

Requirements

Substantial mechanical construction, installation, field engineering or startup experience in data center cooling or comparable critical facilities.
Demonstrated leadership of mechanical contractors or crews, including coordination across organizations without relying on direct reporting authority.
Practical knowledge of cooling, ventilation, hydronic and pumping systems, heat rejection, piping cleanliness and vendor startup requirements.
Ability to review drawings, specifications, submittals, work methods and controls narratives for constructability and installation readiness.
Experience coordinating inspection, pressure testing, flushing, cleaning, balancing prerequisites and controls checkout.
Ability to interpret test results and deficiency records with commissioning specialists and coordinate corrective work, retesting and turnover evidence.
Clear communication and sound judgment when coordinating power, controls, startup and testing dependencies or escalating safety and delivery risks.
Relevant trade, apprenticeship, technical or degree-based preparation, or equivalent practical experience.
Owner-side or specialist-contractor experience with high-density data center cooling, liquid cooling or phased cooling-system startup.
Experience with integrated systems testing, factory or site acceptance activities, and digital commissioning or field-reporting tools.
Relevant mechanical trade, controls, balancing or commissioning qualifications, or professional engineering credentials.
