2) Detailed Design and Engineering Delivery

• Produce design packs: single line diagrams, schematics, panel designs, cable schedules, device layouts, containment requirements, integration interface documents, network topologies (as required).
• Select appropriate technologies and grades of equipment aligned with environment, threat, maintainability, and lifecycle cost.
• Engineer power budgets, UPS autonomy, segregation, EMC considerations, and environmental suitability (IP ratings, temperature, corrosion).
• Ensure designs support safe installation and maintainability (access for servicing, spares strategy, configuration control).

3) Compliance, Assurance, and Governance

• Design in accordance with relevant standards, client governance, and site rules (including safety, electrical, security, and information assurance requirements).
• Participate in design reviews, HAZID/HAZOP or equivalent safety/security assurance activities where applicable.
• Maintain traceability: requirements → design → test → as-built manage design change control.

4) Cyber-Physical Security Alignment

• Work with cybersecurity/architecture teams to ensure secure-by-design principles for networked security systems (segmentation, hardening assumptions, credential management, logging, patching constraints).
• Produce documentation to support risk acceptance and operational security processes (account management, secure maintenance, audit trails).

5) Testing, Commissioning, and Handover

• Define test strategies: FAT/SAT, integrated testing, performance validation, resilience/failover tests, alarm response verification.
• Support commissioning, resolve defects, verify as-built compliance, and produce handover documentation and training inputs.
• Ensure operational readiness: SOPs input, maintenance regimes, spares, and configuration backups.

6) Stakeholder and Supplier Management

• Specify and evaluate supplier solutions review technical submissions, RFIs, deviations, and value engineering proposals.
• Provide technical support to procurement and contract teams (scope clarity, acceptance criteria, warranties, support arrangements).

Deliverables

• User/Operational Requirements (input or authored sections) and System Requirements Specification
• Security System Architecture and integration/interface control documents (ICDs)
• Drawings: GA/device layouts, wiring diagrams, schematics, cabinet layouts, network diagrams
• Schedules: equipment lists, I/O schedules, cable schedules, power/UPS calculations
• Test documentation: FAT/SAT scripts, test evidence requirements, commissioning plans
• As-built pack, O&M manuals review, training materials input, configuration baselines

Skills and Competencies

Technical

• Strong electrical engineering fundamentals: power distribution, protection, earthing/bonding, cable design, fault finding principles.
• Solid understanding of physical security technologies (ACS, IDS, VSS, perimeter detection) and integration patterns.
• Knowledge of resilience engineering (redundancy, autonomy, graceful degradation, fail secure/fail-safe behaviour).
• Competence in drawings and engineering documentation control (CAD and document management practices).
• Familiarity with networking concepts relevant to ESS (IP addressing, VLANs, PoE budgets, bandwidth/storage sizing, time synchronisation).

Experience (Typical)

• 3-8+ years in security systems engineering/design or related building services/controls with significant ESS exposure.
• Experience delivering projects through full lifecycle: concept to handover.
• Experience working under strict governance (design gates, audits, regulated change control) and within live operational sites.
