Engineer - Change Management

Khazna was founded in 2012 and has grown rapidly into becoming the leading and trusted wholesale Data Center provider in the Middle East and North Africa region. Through our Data Centers, we provide industry benchmark levels of power supply and cooling services to better serve the growing need for data center operations in the UAE and wider region.

We are seeking an Engineer – Change Management who will be accountable for the safe, controlled, and effective site-level execution of approved operational and engineering changes within assigned data center facilities. This role applies sound engineering judgment and disciplined change management practices to ensure that all changes impacting electrical, mechanical, controls, and supporting infrastructure systems are implemented in a manner that protects critical load, maintains design redundancy, and ensures personnel safety.

Key Accountabilities:

• Act as the site change focal point for all approved operational and engineering changes impacting electrical, mechanical, controls, and supporting critical infrastructure systems within assigned data center facilities.
• Validate site-level readiness prior to execution, ensuring all prerequisites are satisfied, including technically sound and approved Methods of Procedure (MOPs) and Switching
• Programs (SPOs), engineering risk assessments, rollback and recovery plans, spares and tooling availability, and competent, authorised resources.
• Apply engineering judgement to assess the impact of proposed changes on system redundancy, failure modes, interdependencies, and operational margins, ensuring risks to critical load are clearly understood and controlled.
• Confirm full integration of Permit to Work (PTW) processes, isolation and Lock-Out/Tag-
• Out (LOTO) requirements, access controls, and safety precautions prior to commencement of any change activity.
• Execute standard, normal, and emergency changes in strict accordance with approved engineering documentation, authorised maintenance windows, and defined risk tolerances.
• Coordinate closely with Site Operations, Engineering disciplines, Controls/BMS teams,
• Security, IT where interfacing is required, and third-party vendors to align sequencing, responsibilities, communications, and risk mitigation actions.
• Conduct pre-change and post-change verification activities, including redundancy validation, system behaviour checks, alarm and monitoring verification, and confirmation of stable normal operating conditions.
• Maintain accurate, complete, and timely updates within the Change Management system and asset/configuration records, ensuring equipment status, dependencies, and change outcomes are correctly reflected.
• Prepare site-specific engineering impact assessments, technical risk evaluations, and detailed rollback and recovery procedures to support informed governance decision-making.
• Ensure all change records contain appropriate engineering and execution evidence, including permits, isolation records, test results, readings, screenshots, photographs, commissioning data, and vendor reports, as applicable.
• Verify that all temporary operational measures (e.g. inhibited alarms, bypasses, systems placed in maintenance or test mode) are fully removed, reinstated, and documented following completion.
• Collate and submit accurate technical inputs, readiness confirmations, and site impact summaries for Change Advisory Board (CAB) or equivalent governance review.
• Support the central Change Management function by providing engineering clarification on execution plans, operational constraints, system risks, and residual exposures.
• Participate in post-implementation reviews (PIRs) by validating outcomes against defined success criteria, documenting deviations, near misses, or lessons learned, and contributing to root cause identification and improvement actions.
• Ensure all site-level change activities are executed in compliance with approved engineering standards, internal governance requirements, safety management systems, and applicable regulatory obligations.
• Monitor and report on engineering change performance indicators, including execution success rates, rollback occurrences, emergency change usage, and unauthorised or non-compliant activities.
• Escalate emerging engineering risks, repeated failures, or control weaknesses to site leadership and the central Change Management function in a timely and structured manner.
• Proactively identify opportunities to standardise engineering change execution, improve procedural quality, and reduce risk through repeatable practices, improved documentation, and enhanced readiness controls.
• The role is primarily based within live, mission-critical data center facilities, operating in modern, highly controlled environments that support 24/7 operations and stringent availability, safety, and security requirements.
• The work environment is fast-paced and operationally demanding, requiring high levels of situational awareness, discipline, and adherence to defined procedures to protect critical load, personnel safety, and service continuity.
• The role operates within a culture of operational excellence, reliability, sustainability, and continuous improvement, supporting world-class standards aligned to industry best practice and enterprise governance frameworks.
• The position requires close collaboration with multi-disciplinary teams, including operations, engineering, IT, security, vendors, and central governance functions, often across multiple shifts and time zones.
• Work activities may include planned out-of-hours, night-time, or weekend maintenance windows, as well as participation in emergency response or recovery activities when required.
• The role involves routine exposure to technical plant areas (e.g. electrical rooms, UPS rooms, generator yards, cooling plant, and white space), necessitating compliance with all site safety rules, PPE requirements, and access controls.
• Occasional travel may be required to support change execution across multiple sites, engage with OEMs or vendors, participate in audits, or attend relevant technical or industry forums.

Minimum Qualifications:

• Bachelor’s degree in electrical engineering, Mechanical Engineering, Building Services
• Engineering, Energy Engineering, Facilities Engineering, or a closely related engineering discipline.
• Formal technical training or certification in critical facilities, data center operations, or building services engineering is strongly preferred.
• Additional certifications in safety and risk management (e.g. NEBOSH, IOSH, electrical safety,
• HV/LV authorisation, OEM technical training) are advantageous.

Minimum Experience:

• 3–5 years’ experience working in a mission-critical or safety-critical environment, such as data centers, utilities, power generation, industrial facilities, hospitals, airports, or similar infrastructure-intensive operations.
• Demonstrated hands-on experience planning and executing engineering changes affecting electrical, mechanical, cooling, controls, or integrated MEP systems within live operational environments.
• Proven experience executing standard, normal, and emergency engineering changes within controlled maintenance windows, with a strong understanding of redundancy, failure modes, and recovery strategies.
• Practical experience coordinating multi-disciplinary engineering teams and third-party vendors, including OEMs, during high-risk or time-critical change activities.
• Experience maintaining accurate engineering change records, asset data, and configuration documentation, ensuring traceability of equipment status and system dependencies.

Job-Specific Skills (Generic/ Technical):

• Strong understanding of data center and critical infrastructure systems, including power distribution, UPS, generators, cooling systems, controls, BMS/EPMS, and associated protection and monitoring systems.
• Ability to evaluate engineering risk associated with changes, including assessment of redundancy impact, single points of failure, system interdependencies, transient risks, and operational margins.
• Competence in reviewing and validating Methods of Procedure (MOPs) and Switching Programs (SPOs) to ensure technical accuracy, safe sequencing, and recoverability.
• Practical knowledge of Permit to Work (PTW) systems, Lock-Out/Tag-Out (LOTO), electrical and mechanical isolations, and safety-critical execution controls.
• Ability to interpret and challenge technical documentation, including drawings, schematics, single-line diagrams, control philosophies, and operating procedures
