Senior Manager, Mechanical Engineer
About The Position
TransGrid Energy is a renewable energy company that invests in, develops, owns, and operates utility-scale battery energy storage systems and photovoltaic projects. As an affiliate of Hanwha Group, the company aims to advance clean energy through sustainable and reliable power solutions. The Senior Manager, Mechanical Engineer will own cooling and mechanical design for data center projects, helping ensure high-density IT loads remain thermally safe, reliable, and energy efficient across traditional air-cooling and emerging liquid-cooling technologies. The role covers mechanical systems from concept and plant sizing through detailed design, equipment selection, construction, commissioning, and turnover. Designs must balance thermal performance, reliability, constructability, cost, and energy and water efficiency. Within the Engineering & Preconstruction organization, the position works cross-functionally with Electrical, Controls, Power Systems, Construction, Preconstruction, and Solutions Engineering to integrate mechanical systems with broader data center infrastructure. The role requires ownership of technical decisions, design review, equipment specification, and support through construction and commissioning. Travel may be required depending on business and project needs. Applicants must already be authorized to work in the United States; the company will not sponsor work authorization.
Requirements
- Approximately 8 or more years of experience designing mechanical and cooling systems for data centers, mission-critical facilities, or similarly complex industrial environments.
- Demonstrated experience with data center cooling systems, including chilled-water plants, air cooling, mechanical distribution, and controls.
- Strong understanding of high-density IT cooling requirements and the relationships among rack density, thermal loads, cooling capacity, redundancy, and facility efficiency.
- Experience with plant sizing, redundancy, PUE, WUE, piping and pumping design, and mechanical controls sequences.
- Working knowledge of ASHRAE TC 9.9 and data center thermal-management practices.
- Bachelor's degree in Mechanical Engineering (BSME) or a related engineering discipline.
- Professional Engineer (PE) license required or strongly preferred.
- Experience specifying, evaluating, and supporting procurement of major mechanical equipment and long-lead items.
- Ability to work effectively with Electrical, Controls, Construction, Preconstruction, vendors, and other engineering teams.
- Experience supporting mechanical commissioning, startup, and performance verification.
- Strong analytical, communication, and problem-solving skills, and ability to make sound engineering decisions in complex, fast-moving project environments.
- Authorization to work in the United States before joining; the company will not sponsor or assist with sponsorship for work authorization.
- Travel may be required depending on business and project needs.
Nice To Haves
- Experience with direct-to-chip or immersion cooling is highly desirable.
- Professional Engineer (PE) license is strongly preferred.
Responsibilities
- Own mechanical and cooling design for data center projects from concept and basis of design through construction, commissioning, and turnover.
- Design and evaluate chilled-water, air-cooled, and liquid-cooling systems, including CRAH/CRAC units, cooling distribution units (CDUs), direct-to-chip cooling, immersion cooling, and associated infrastructure.
- Lead mechanical plant sizing, capacity planning, redundancy strategies, and system architecture for high-density IT loads and required availability.
- Develop and review piping, pumping, heat-rejection, and mechanical-distribution systems for reliability, efficiency, and constructability.
- Optimize systems for PUE and WUE while balancing thermal requirements, energy consumption, water usage, capital cost, and operational efficiency.
- Develop and review controls sequences and mechanical-controls integration with Controls and Electrical teams to support effective BMS operation.
- Specify and evaluate major mechanical equipment and support procurement of long-lead equipment through technical reviews, vendor coordination, and equipment selection.
- Coordinate mechanical interfaces with Electrical, Controls, Construction, Preconstruction, and other engineering disciplines, resolving design conflicts and constructability issues.
- Support construction, commissioning, and startup by reviewing submittals, responding to RFIs, resolving field issues, and verifying thermal performance and mechanical system operation.
- Perform other duties and special projects as assigned.
