Systems Engineer (Systems Commissioning Specification Author)

The author translates design intent, technical requirements, and operational needs into structured commissioning documentation that supports safe, efficient, and compliant system delivery.

Key Responsibilities

Specification Development

• 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.

Requirements & Design Integration

• Interpret system requirements, functional specifications, and design outputs.
• Collaborate with design engineers to ensure commissioning requirements are embedded early in the lifecycle.
• Identify gaps or risks in design from a commissioning perspective.

Stakeholder Engagement

• Work closely with:
  • Systems Engineers
  • Design Authorities
  • Project Managers
  • Commissioning Teams
  • Operations & Maintenance stakeholders
• Facilitate reviews and workshops to validate commissioning approaches.

Verification & Validation Planning

• 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.

Compliance & Standards

• 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.

Documentation & Configuration Management

• Produce high-quality, structured documentation with clear version control.
• Ensure consistency across documentation sets.
• Manage updates in response to design changes or operational feedback.

Continuous Improvement

• Capture lessons learned from commissioning activities.
• Improve templates, standards, and authoring practices.
• Contribute to organisational commissioning best practices.

• 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.

Competencies

• 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
