• Test control sequences, alarms, interlocks, time schedules and safety functions.
• Integrate third-party equipment using protocols such as BACnet, Modbus and M-Bus.
• Upgrade or replace legacy controllers while minimising disruption to occupied buildings.
• Analyse system performance and recommend improvements to comfort, reliability and energy efficiency.
• Provide remote diagnostic and technical support where appropriate.
• Produce clear service reports, commissioning documentation, point schedules and records of software changes.
• Explain identified faults and recommended remedial work clearly to customers.
• Liaise with project managers, control-panel engineers, electrical installers, subcontractors and client representatives.
• Manage assigned work efficiently and identify any additional materials or return visits required.
• Participate in the engineer call-out rota where applicable.
• Work safely and comply with site rules, risk assessments and company health and safety procedures.

The successful candidate should have:

• Previous experience servicing or commissioning commercial BMS and HVAC control systems.
• Strong knowledge of HVAC plant and common control strategies.
• Competence in electrical fault-finding and interpreting control-panel drawings and wiring diagrams.
• Experience with one or more major BMS platforms, ideally Trend, ABB Cylon or EasyIO.
• Additional experience with Tridium Niagara, Siemens, Schneider Electric, Satchwell, Heatmiser or other open-protocol systems would be advantageous.
• Experience commissioning controllers, supervisor software and front-end graphics.
• An understanding of BACnet and Modbus integration.
• The ability to complete point-to-point testing and identify installation or panel-wiring defects.
• A practical understanding of networking, IP addressing and BMS communications.
• The ability to work independently while knowing when to seek additional technical support.
• Good written communication and accurate reporting skills.
• A full UK driving licence.

Desirable qualifications

• Recognised electrical, controls or building-services qualification.
• Manufacturer training or certification in Trend, ABB Cylon, EasyIO, Tridium Niagara or Siemens systems.
• ECS or CSCS card.
• 18th Edition electrical qualification.
• Relevant health and safety training, such as SSSTS, IPAF or PASMA.
• Experience with energy monitoring, metering or critical-power monitoring systems.
• Experience working in occupied, live or critical environments.

Personal qualities

We are looking for someone who is:

• Methodical and persistent when diagnosing complex faults.
• Comfortable dealing directly with customers and facilities teams.
• Reliable, organised and able to manage a mobile workload.
• Commercially aware without compromising engineering quality or safety.
• Proactive in identifying potential failures and opportunities for optimisation.
• Willing to develop across different manufacturers and control platforms.
• Capable of representing the business professionally on customer sites.

What the role offers

• A varied position covering service, commissioning, integration and optimisation.
• Exposure to multiple leading BMS manufacturers and open-protocol technologies.
• Projects ranging from individual controller upgrades to complete multi-building BMS installations.
• Support from experienced project, software, panel-building and installation teams.
• Ongoing technical and manufacturer training.
• Opportunities to develop into senior engineering, project management or specialist controls positions.
• A stable role within an established and growing BMS engineering business.

Working arrangements

The position is field-based, with most work undertaken across the Midlands, Wales and North West. Travel elsewhere in the UK and occasional overnight stays may be required.

Some commissioning, upgrade or shutdown work may need to be completed outside normal operating hours to minimise disruption to customers. Any call-out rota, overtime arrangements and travel expectations will be confirmed as part of the employment offer.

How to apply

Please submit an up-to-date CV outlining your BMS service and commissioning experience, the control systems you have worked with, relevant qualifications and your current location.
