[Hiring] Lead Commissioning Engineer @OnQGlobal Inc

Role Description

OnQCx is seeking an experienced Lead Commissioning Engineer to develop Level 4 Functional Performance Test (FPT) procedures and Level 5 Integrated Systems Test (IST) scripts for large-scale data center projects. This position requires strong multidisciplinary expertise in mechanical, electrical, and instrumentation and controls (I&C) systems, with an emphasis on understanding system interactions, operating sequences, redundancy, and failure modes.

The successful candidate will independently review engineering drawings, P&IDs, electrical single-line diagrams, Sequences of Operation (SOOs), equipment submittals, installation procedures, and O&M manuals to develop comprehensive, technically accurate, and executable commissioning test scripts. This is primarily a technical engineering and test development role, not a field commissioning management position.

Key Responsibilities

• Engineering Review & Analysis
  • Review mechanical, electrical, and I&C drawings, P&IDs, single-line diagrams, SOOs, equipment submittals, installation procedures, and O&M manuals.
  • Analyze system operating sequences, control logic, interlocks, alarms, redundancy configurations, and equipment failure responses.
  • Identify design discrepancies, missing information, and technical conflicts requiring engineering clarification.
  • Establish test requirements and acceptance criteria based on design intent, specifications, and manufacturer documentation.
• Level 4 – Functional Performance Test Development
  • Develop detailed, executable L4 FPT scripts for mechanical, electrical, and controls systems.
  • Define test prerequisites, procedures, expected results, measurable acceptance criteria, and documentation requirements.
  • Develop test scenarios for normal operation, startup/shutdown, equipment staging, failure conditions, and automatic recovery.
  • Verify control sequences, interlocks, alarms, protective functions, and equipment redundancy.
• Level 5 – Integrated Systems Test Development
  • Develop L5 IST scripts validating interactions between electrical distribution, standby power, mechanical cooling, and controls systems.
  • Create failure-mode scenarios involving utility outages, generator and UPS failures, cooling interruptions, and controls failures.
  • Validate redundancy, failover, transfer sequences, system recovery, and integrated performance under abnormal operating conditions.
  • Define expected system responses, timing requirements, monitoring points, and acceptance criteria.
• Technical Coordination & Quality
  • Coordinate with design engineers, contractors, OEMs, controls integrators, and commissioning teams.
  • Lead technical reviews of test scripts and resolve engineering questions.
  • Maintain test documentation, revision control, and traceability to approved design requirements.
  • Provide technical support during commissioning execution, troubleshooting, and deficiency resolution.
  • Ensure scripts are complete, accurate, and ready for field execution.

Qualifications

• Bachelor's degree in Mechanical, Electrical, Controls Engineering, or related discipline; equivalent relevant experience considered.
• Minimum 8 years of engineering or commissioning experience, including 5 years in data center or mission-critical facilities.
• Demonstrated experience personally developing L4 FPT and L5 IST scripts.
• Strong multidisciplinary understanding of mechanical, electrical, and I&C systems.
• Ability to independently interpret complex engineering documents and translate requirements into executable test procedures.
• Experience evaluating system dependencies, failure modes, redundancy, and integrated operating sequences.
• Strong technical writing, analytical, and problem-solving skills.

Requirements

• High school diploma or equivalent.
• Experience in project administration, document control, quality support, commissioning support, or a related role.
• Proficiency in Microsoft Excel, Word, Outlook, and shared document platforms. CxAlloy Commissioning Database.
• Strong organizational skills and attention to accuracy, version control, and deadlines.
• Clear written and verbal communication skills.
• Ability to manage multiple priorities and follow up consistently with multiple stakeholders.
• Ability to work independently while supporting a multidisciplinary project team.
• Associate degree, technical training, or equivalent relevant experience.
• Experience supporting construction, data center, industrial, mission-critical, or building systems projects.
• Familiarity with QA/QC processes, commissioning workflows, inspections, deficiency tracking, and turnover documentation.
• Experience with commissioning databases, construction management software, or electronic document management systems.
• Ability to interpret equipment identifiers, system references, and basic construction documentation.
