Principal BMS & PMS Controls Engineer

Accountabilities: Define and own the global BMS and PMS controls architecture, including system boundaries, network configurations, redundancy strategies and integration with facility monitoring and compute infrastructure. Develop and maintain the controls standards library, covering sequences of operation, points schedules, alarm philosophies, naming conventions, and Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) requirements. Establish technical requirements for high-density AI data centre environments, including liquid cooling systems, Coolant Distribution Unit (CDU) integration and power-to-compute interfaces. Act as the final technical authority on controls design deviations, vendor proposals and integration challenges across multiple international sites. Collaborate with procurement teams to define vendor strategies, technical evaluation criteria and supplier selection standards. Establish operational technology (OT) security requirements in collaboration with cybersecurity specialists, including network segmentation, access controls and secure remote support. Analyse operational data, incidents and system performance to continuously improve controls standards, reference designs and engineering practices. Provide technical guidance and mentorship to controls engineers and specialist partners, strengthening technical expertise and consistency across the organisation. Requirements: At least 12 years of professional experience in Building Management Systems (BMS), Power Management Systems (PMS) or mission-critical controls engineering, with proven experience in the data centre sector. Demonstrated expertise in defining controls architectures and establishing technical standards across multiple sites or an international project portfolio. Strong understanding of electrical and mechanical control sequences, supervisory control platforms and industrial communication protocols, particularly BACnet and Modbus. Proven experience making, communicating and defending complex technical decisions involving vendors, engineering consultants, designers and senior stakeholders. Practical experience defining and overseeing FAT, SAT and integrated systems testing (IST) procedures for mission-critical controls environments. Strong stakeholder management, communication and influencing skills, with the ability to drive alignment across multidisciplinary teams and geographical regions without relying on direct reporting authority. Strategic thinking, sound technical judgement and a proactive approach to identifying risks and implementing engineering improvements. Nice to have: Experience with controls systems for high-density AI data centres, direct liquid cooling and advanced thermal management technologies. Nice to have: Knowledge of OT cybersecurity principles and controls network architecture, including IEC 62443. Nice to have: Experience standardising controls architectures, specifications and engineering practices across international data centre portfolios. Benefits: Competitive salary package based on the responsibilities and value of the role, rather than previous salary. Equity participation, offering the opportunity to share in the organisation's long-term growth and success. Retirement and pension contributions. Comprehensive healthcare, wellbeing and insurance benefits. Generous annual paid leave entitlement. Opportunity to take on a high-impact technical leadership position within a rapidly growing AI infrastructure environment. Exposure to large-scale, international projects across Europe and North America. Opportunity to shape global engineering standards and influence the development of next-generation mission-critical infrastructure. Supportive working environment focused on professional development, trust, autonomy and work-life balance. Benefits may vary depending on the country of employment and applicable local regulations.
