The Position
Mission Critical Engineers is seeking a Mechanical Commissioning Associate to support the field execution of commissioning activities on complex data centre and mission-critical projects.
This is a site-based technical role supporting projects in Regina, Saskatchewan. The Mechanical Commissioning Associate will work alongside the Lead Data Centre Commissioning Engineer & Project Manager and the commissioning team during system startup, test preparation, functional testing, integrated systems testing, and turnover.
The role requires a solid understanding of mechanical systems, cooling infrastructure, controls, and system interdependencies, together with strong attention to detail, technical documentation skills, and the ability to work effectively with owners, contractors, OEMs, engineers, and project teams.
Responsibilities
Support and actively participate in L1–L5 commissioning activities, including factory acceptance testing, site acceptance testing, installation verification, pre-functional testing, functional performance testing, and integrated systems testing.
Participate in field verification, testing, troubleshooting, and documentation of mechanical systems; record test results, deficiencies, corrective actions, and commissioning progress.
Assist with commissioning of critical cooling infrastructure, including chillers, cooling towers, pumps, CRAH/CRAC units, air-handling systems, CDUs, liquid-cooling systems, hydronic systems, BMS, controls, alarms, and interlocks.
Support verification of mechanical-system redundancy, control sequences, alarms, failover, recovery, maintainability, and response to abnormal operating conditions.
Review mechanical drawings, specifications, submittals, equipment documentation, test procedures, control sequences, and operating manuals.
Read and interpret mechanical drawings, P&IDs, control diagrams, sequences of operation, specifications, and equipment manuals.
Conduct site inspections and verify system installation, test readiness, and completion of pre-functional requirements.
Assist with the development, review, and execution of test plans, test scripts, checklists, test matrices, and acceptance criteria.
Support testing of BMS points, alarms, monitoring, interlocks, equipment safeties, automatic sequences, and system response.
Attend commissioning, test-readiness, and technical coordination meetings with owners, contractors, OEMs, consulting engineers, and MCE personnel.
Coordinate with contractors and OEM representatives during equipment startup, testing, issue resolution, and documentation review.
Maintain accurate test records, site observations, deficiency logs, meeting minutes, and project-status updates.
Support test-day logistics, including site access, equipment availability, safety controls, temporary loads, required documentation, and OEM attendance.
Assist in tracking deficiencies, verifying corrective actions, and confirming readiness for subsequent testing stages.
Support owner training, turnover documentation, and transition of systems to the facility operations team.
Follow MCE and project safety requirements at all times.
Work primarily from the Regina project site and travel to other client and project locations across Canada, as required.
Qualifications
Diploma or bachelor’s degree in Mechanical Engineering, Mechanical Engineering Technology, Building Systems Engineering, or a related discipline.
Experience in mechanical construction, testing, commissioning, design, operations, maintenance, or related technical work is preferred.
Foundational understanding of HVAC, hydronic, cooling, controls, and mechanical-system operation.
Foundational understanding of mission-critical mechanical systems, redundancy, availability, resiliency, controls, and system interdependencies.
Ability to read and interpret mechanical drawings, P&IDs, control diagrams, specifications, and equipment manuals.
Strong attention to detail, organization, and technical documentation skills.
Strong written and oral communication skills, including the ability to prepare clear technical notes, test records, and reports.
Collaborative, dependable, and professional approach; able to work independently in the field and effectively within a multidisciplinary team.
Proficiency with Microsoft Office and relevant engineering, analysis, or documentation software.
Ability to work safely in active construction and mission-critical environments.
Valid driver’s licence and ability to travel 15–50% as required.
Preferred Qualifications
Experience in data centres, healthcare, industrial, laboratory, utility, or other mission-critical environments.
Experience with chilled-water systems, cooling towers, CRAH/CRAC units, air-handling systems, liquid cooling, CDUs, BMS, or data centre cooling infrastructure.
Familiarity with commissioning processes and L1–L5 testing.
EIT designation or eligibility for registration as an Engineer-in-Training with APEGS is an asset.
