Systems Engineer – Systems Commissioning Specification Author

Responsibilities

• The Systems Commissioning Specification Author is responsible for developing clear, accurate, and comprehensive commissioning specifications for complex systems.
• This role ensures that all systems are fully tested, validated, and handed over in accordance with project requirements, regulatory standards, and operational expectations.
• The author translates design intent, technical requirements, and operational needs into structured commissioning documentation that supports safe, efficient, and compliant system delivery.
• Develop commissioning specifications for systems and subsystems (e.g., mechanical, electrical, control, or integrated systems).
• Define commissioning scope, strategy, and verification activities.
• Produce test procedures, acceptance criteria, and validation methodologies.
• Ensure specifications align with design documentation, requirements, and standards.
• Collaborate with design engineers to ensure commissioning requirements are embedded early in the lifecycle.
• Identify gaps or risks in design from a commissioning perspective.
• Work closely with Systems Engineers, Design Authorities, Project Managers, Commissioning Teams, Operations & Maintenance stakeholders.
• Facilitate reviews and workshops to validate commissioning approaches.
• Define test plans, inspection regimes, and commissioning sequences.
• Develop System Acceptance Test (SAT), Factory Acceptance Test (FAT), and Site Acceptance Test (SAT) documentation.
• Ensure traceability between requirements and test cases.
• Ensure specifications comply with industry standards (e.g., ISO, IEC, BS, or sector‑specific requirements), safety regulations and statutory compliance, project‑specific governance frameworks.
• Maintain audit‑ready documentation.
• Produce high‑quality, structured documentation with clear version control.
• Capture lessons learned from commissioning activities.
• Improve templates, standards, and authoring practices.
• Contribute to organisational commissioning best practices.

• Degree in Engineering, Systems Engineering, or a related technical discipline (or equivalent experience).
• Relevant professional certifications (desirable).
• Essential Experience in writing technical or engineering specifications.
• Strong understanding of systems engineering principles (e.g., lifecycle, requirements, V&V).
• Experience in commissioning or testing complex systems.
• Ability to translate technical designs into structured test and commissioning activities.
• Excellent written communication skills with attention to detail.
• Experience with document control and configuration management.
• Desirable Experience in regulated industries (e.g., rail, nuclear, defence, utilities, aerospace).
• Knowledge of systems integration and interface management.
• Familiarity with requirements management tools (e.g., DOORS, Jama).
• Understanding of digital engineering or model‑based systems engineering (MBSE).
• Chartered or working towards professional accreditation.
• Document management systems (SharePoint, Aconex, etc.).
• Systems modelling tools (e.g., Enterprise Architect, Capella).
• Requirements management tools (DOORS, Jama, Polarion).
• MS Office suite (Word, Excel, Vision).
