Who We Are

Thermo Systems is a global, full-service control systems integration partner delivering premier class automation solutions across the Energy, Life Sciences, and Mission Critical markets.

Guided by The Thermo Way, we are unified, dynamic, and committed to delivering excellence. Our culture is grounded in three core principles:

• Employee Success – investing in our people and their growth
• Customer Success – delivering reliable, high-quality solutions
• Financial Strength – operating with discipline and long-term focus

We believe strong teams, trusted partnerships, and technical excellence drive sustainable success.

The Opportunity

The Commissioning Engineer will lead and execute advanced commissioning activities across mission-critical projects, with a focus on BMS, EPMS, PLC, and SCADA systems. This role goes beyond field validation, requiring the ability to diagnose system issues, modify and develop control logic, and support system integration during commissioning and delivery phases.

Working closely with Engineering, Integration, and Operations teams, you will play a key role in ensuring systems are not only installed correctly, but functionally robust, fully integrated, and aligned with design intent and operational requirements.

This position is ideal for an experienced commissioning professional with strong controls expertise, capable of bridging the gap between design, software, and field execution in high-availability environments.

This position is ideal for professionals who value accountability, technical rigor, and hands-on execution in environments where safety, performance, and reliability matter every day.

What You’ll Do

Core Responsibilities:

• Lead commissioning activities for BMS, EPMS, PLC, and SCADA systems across mission-critical/data centre projects
• Perform advanced system validation including point-to-point checks, functional testing, and integrated systems testing (IST)
• Diagnose, troubleshoot, and resolve complex system issues across controls, networking, and field devices
• Modify, develop, and optimise PLC logic and SCADA/BMS software during commissioning phases
• Support system integration between mechanical, electrical, and control systems to ensure cohesive operation
• Validate control sequences under normal, failure, and redundancy scenarios (including failover testing)
• Support and lead Level 3–5 commissioning activities, including client witnessing and sign-off
• Review design documentation, control narratives, and software to ensure alignment with field implementation
• Produce and maintain detailed commissioning reports, test scripts, and issue logs

Collaboration & Communication:

• Coordinate with cross-functional teams to align scope, schedule, and deliverables.
• Communicate clearly and proactively with internal teams, customers, and partners.
• Identify and escalate risks, constraints, or scope changes early.

Quality, Safety & Process

• Adhere to company policies, QMS requirements, and established safety standards.
• Deliver accurate, high-quality results with strong attention to detail.
• Identify opportunities for process improvement and contribute to stronger execution and efficiency.

What We’re Looking For

Education & Experience:

• Degree or equivalent experience in Electrical Engineering, Controls, Automation, or related discipline
• 5+ years’ experience in commissioning, controls engineering, or system integration
• Strong experience in mission-critical/data centre environments

Skills & Qualifications:

• Strong knowledge of BMS, EPMS, PLC, and SCADA systems (e.g., Rockwell, Siemens, Ignition, Schneider)
• Experience developing or modifying PLC code and SCADA/BMS graphics during live project environments
• Understanding of electrical systems, control architectures, and networked systems
• Ability to interpret and validate control sequences, schematics, and design documentation
• Proven troubleshooting capability across software, hardware, and integration layers
• Experience with commissioning processes including FAT, SAT, and IST (Level 1–5)
• Effective communication and teamwork skills
• Ability to manage priorities in fast-paced, high-pressure environments
• Strong problem-solving and decision-making capability
• Commitment to quality, safety, and accountability
• Willingness to travel and work on-site as required

What You’ll Get

• Competitive compensation with annual bonus opportunity
• In-house and external technical training opportunities
• Exposure to complex, high-impact automation projects
• A collaborative culture built on integrity, accountability, and teamwork
