The Role
The CX Mechanical Engineer is responsible for planning, execution, and management of commissioning activities for mission‑critical mechanical systems within hyperscale data center environments. This role ensures that all mechanical and thermal infrastructure is installed, tested, integrated, and handed over in full compliance with project requirements, safety standards, and operational objectives, supporting high‑availability and energy‑efficient operations.
Responsibilities
- Lead and manage the end‑to‑end commissioning process for mechanical systems, from pre‑functional testing through integrated systems testing (IST) and final handover.
- Ensure commissioning activities are executed in accordance with approved commissioning plans, project schedules and quality standards.
- Coordinate phased and systems‑based commissioning strategies typical of hyperscale delivery model.
- Commission and validate critical mechanical infrastructure, including chilled water systems (chillers, pumps, cooling towers, heat exchangers), airside systems (CRAC/PAHUs, AHUs, FWUs), direct‑to‑chip, liquid cooling or hybrid cooling systems, HVAC distribution systems (ductwork, piping, valves, dampers), fuel oil and lube oil systems, make‑up water, water treatment and blowdown systems.
- Verify system performance under normal, abnormal, and failure conditions.
- Validate thermal performance, capacity, control response, and efficiency against design intent and client requirements.
- Plan, coordinate and lead mechanical commissioning activities in collaboration with design engineers, construction teams, vendors, controls specialists and operations stakeholders.
- Act as the primary technical authority for mechanical commissioning issues on site.
- Support construction readiness, system turnover and commissioning sequencing in fast‑track hyperscale environments.
- Ensure seamless integration of mechanical systems with electrical power systems, controls, BMS, EPMS, fire/life safety systems and IT load and white‑space requirements.
- Validate system redundancy (N, N+1, 2N), fault tolerance, and maintainability to support mission‑critical operations.
- Lead functional performance testing and integrated systems testing involving mechanical failure scenarios.
- Develop and manage commissioning documentation, including commissioning plans and schedules, mechanical test procedures and functional performance scripts, method statements and risk assessments, final commissioning reports, as‑built records and handover documentation.
- Provide clear, accurate progress, risk and readiness reports to project and client stakeholders.
- Ensure all mechanical systems and commissioning activities comply with applicable codes, standards and best practices such as ASHRAE (TC9.9), CIBSE, SMACNA, IPC, IEC, ISO, local authority requirements, Uptime Institute Tier Standards and TIA‑942 and client‑specific hyperscale standards.
- Support third‑party audits, peer reviews and certifications where required.
- Plan, coordinate and lead FAT and SAT activities for mechanical equipment and packaged systems.
- Review vendor submittals, test data and corrective actions to ensure equipment readiness for site installation and integration.
- Witness performance testing of major plant (chillers, PAHUs, cooling towers, packaged plant).
- Identify technical, schedule, operational and safety risks related to mechanical commissioning.
- Implement mitigation strategies and lead root‑cause analysis and troubleshooting to resolve issues efficiently.
- Support rapid issue resolution in live or partially energized data hall environments.
- Demonstrate a strong understanding of mechanical and process safety, including pressurized systems, rotating equipment, chemical treatment systems and live data center environments.
- Ensure all commissioning activities comply with health and safety regulations, permit‑to‑work systems, confined space requirements and lock‑out/tag‑out procedures.
- Promote and enforce a strong safety culture across all commissioning activities.
- Lead and support contractors, subcontractors, provide technical guidance, training and oversight.
- Interface effectively with client operations teams to ensure a smooth transition to steady‑state operations.
- Adhere to company policies, procedures and quality management systems.
- Capture lessons learned and promote continuous improvement in commissioning methodologies, energy performance and reliability outcomes across hyperscale data center projects.
Qualifications
- Proven track record in commissioning critical mechanical systems within data centers or other mission‑critical facilities.
- Strong understanding of data center cooling architectures, including air‑cooled and water‑cooled systems, N, N+1 and 2N redundancy, containment strategies and liquid/hybrid cooling systems (desirable).
- Experience validating mechanical system performance under normal, abnormal and failure scenarios, including loss‑of‑power and fail‑over events.
- Solid knowledge of controls and automation systems such as BMS, plant controls, sequencing, integration with EPMS and IT load signals.
- Proven experience developing Functional Performance Test (FPT) and Integrated Systems Test (IST) scripts and leading on‑site teams.
- Working knowledge of commissioning Life Safety and critical interfaces, including fire alarm, smoke control, purge systems and emergency shutdowns.
- Demonstrated ability to review mechanical designs, calculations and specifications from a commissionability, operability and maintainability perspective.
- Proficiency with mechanical and building services design tools such as AutoCAD; familiarity with BIM platforms (Revit, Navisworks); experience with project management tools (MS Project or equivalent); experience with commissioning and construction management platforms such as CxAlloy, Procore, Compass.
- Working knowledge of data analytics, trend logs, performance data for system validation and reporting.
- Exposure to cloud‑based client platforms (Google, Microsoft, Amazon) is advantageous.
- Demonstrated experience managing mechanical commissioning activities across schedule and resource constraints.
- Proven capability to conduct technical audits and operational readiness assessments of existing facilities, including installed equipment verification, system performance evaluation and compliance with design intent and operational standards.
- Experience delivering projects across the full data center lifecycle and familiarity with hyperscale delivery models.
- Strong leadership, organisational and interpersonal skills; effective communicator; highly developed analytical and troubleshooting skills.
- B.Tech in Mechanical Engineering (B.E. or equivalent).
- 7+ years of hands‑on experience in testing and commissioning of mechanical systems in mission‑critical or large‑scale commercial facilities.
- Minimum 5 years of commissioning experience within the data center industry, including leadership of IST.
- Strong working knowledge of relevant standards (ASHRAE TC9.9, CIBSE, SMACNA, Uptime Institute Tier, TIA‑942).
