Job Title: Senior Mechanical Engineer – Mission Critical / Data Centers

Location: Houston, Texas

Experience: 5+ years professional experience; 8+ years preferred; Data Center experience preferred

Role Overview

We is seeking an experienced Senior Mechanical Engineer to support the design and

delivery of major data center developments in the United States.

The role will be based in Houston, Texas, working closely with the local client development team

while forming part of a wider international design and engineering team.

The successful candidate will provide local mechanical engineering support across design

development, localization, procurement and construction. The role requires relevant data center

or mission-critical experience, strong knowledge of US mechanical codes and standards, and the

ability to work independently while coordinating without discipline leads based internationally.

This is a technically hands-on position with a strong focus on critical cooling and associated data

center mechanical infrastructure.

Roles and Responsibilities

1. Provide mechanical engineering support for hyperscale, AI and other mission-critical data

center developments in the United States.

2. Act as a local mechanical engineering interface between the client team, design

consultants, EPC contractors, vendors and other project stakeholders.

3. Review and develop mechanical design documentation including calculations,

schematics, equipment schedules, specifications and technical reports.

4. Support the design and technical review of critical cooling systems including chilled-water

systems, air-cooled and water-cooled plant, CRAH units, fan walls, CDUs, pumps, heat

rejection systems, ventilation and associated mechanical infrastructure.

5. Support the design and review of high-density and liquid-cooling infrastructure and

associated interfaces where applicable.

6. Advise us and client teams on localization of designs for applicable US, Texas and local

code, regulatory and authority requirements.

7. Support coordination with Authorities Having Jurisdiction (AHJs), local consultants and

permitting teams as required.

8. Review consultant, EPC and vendor designs for compliance with project requirements,

design intent, applicable codes and good engineering practice.

9. Identify technical risks, design deviations, coordination issues and potential compliance

concerns and communicate these clearly to the wider project team.

10. Coordinate mechanical requirements and interfaces with electrical, architectural,

structural, controls, BIM and other engineering disciplines.

11. Support technical evaluation of equipment, vendors and alternative mechanical design

solutions.

12. Participate in design reviews, value engineering, technical workshops and

multidisciplinary coordination meetings.

13. Review technical submittals, shop drawings, RFIs and other construction-stage

information where required.

14. Undertake site visits, surveys, inspections and construction or commissioning support as

required.

15. Provide direct technical support to the Houston-based client development team on

day-to-day project matters.

16. Coordinate closely with our mechanical and multidisciplinary design leadership based

internationally, maintaining clear communication of decisions, risks and actions. 17.

Contribute to the development and improvement of a US data center design standards,

specifications and technical processes.

Qualifications and Experience

● Bachelor’s Degree in Mechanical Engineering from an accredited institution. 

● 5+ years of relevant professional mechanical engineering experience, with 8+ years preferred.

● Meaningful experience in data center or mission-critical mechanical design, with

hyperscale and/or high-density data center experience strongly preferred. 

● Experience working on projects in the United States.

● Strong working knowledge of US mechanical codes, standards and engineering practice

relevant to mission-critical facilities.

● Strong understanding of critical cooling infrastructure and HVAC systems used in

large-scale data centers.

● Experience working within multidisciplinary consultancy, owner-side, EPC, design-build or

contractor environments.

● Ability to review complex technical designs and identify material compliance,

performance and coordination issues.

● Experience supporting projects through design development and construction stages. 

●Strong written and verbal communication skills.

● Ability to operate effectively and independently within a geographically distributed

engineering team.

Professional Registration

● Professional Engineer (PE) registration in Texas is strongly preferred. 

● Candidates holding an active PE license in another US jurisdiction who are suitably

qualified and able to obtain Texas licensure will also be considered.

Preferred Experience

● Hyperscale, colocation or AI / high-density data center projects.

● Chilled-water and central plant systems.

● Liquid cooling and CDU-based systems.

● CRAH, fan-wall and high-density cooling solutions.

● Large-scale mechanical plant and hydronic systems.

● EPC and design-build project delivery.

● Technical due diligence and owner-side design review.

● Texas permitting and AHJ processes.

● Construction, testing and commissioning of mission-critical mechanical systems. 

● Familiarity with Revit/BIM-based multidisciplinary coordination.

Reporting and Working Structure

The position will be based in Houston and work closely with the local client development team.

The engineer will form part of a wider design team, with functional technical management

provided by our senior mechanical/design leadership based internationally. The role therefore

requires an individual capable of managing day-to-day technical matters independently while

maintaining effective coordination with the wider engineering team.
