Job description
Design, engineer and assure integrated electronic security systems (ESS) for Critical National Infrastructure (CNI) sites (e.g., energy, water, transport, telecoms, defence-related estates). The role ensures electronic & physical security solutions are safe, compliant, resilient, maintainable, and proportionate to assessed risk-often within high-assurance environments and under strict governance
Scope and typical systems
- Access Control Systems (ACS): door controllers, credential technologies, biometrics, turnstiles, vehicle access.
- Intruder Detection Systems (IDS): perimeter and internal detection, alarm routing, graded signalling.
- Video Surveillance (CCTV/VSS): fixed/PTZ, analytics, storage, evidential export.
- Perimeter security electronics: fence detection, radar, thermal, gates/barriers interfacing.
- Intercom/help points, duress/panic alarms, lockdown/alerting functions.
- Security management and integration platforms: PSIM, VMS, access control management, event correlation., * Translate security risk assessments, threat models and operational requirements into clear engineering requirements and performance specs.
- Develop security design concepts (architecture options, resilience models, failure modes, coverage principles) aligned to the site's criticality.
- 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.
- Design in accordance with relevant standards, client governance and site rules (including safety, electrical, security and information assurance requirements).
Requirements
Do you have experience in IDS?, * 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).
Qualifications and training (typical)
- HNC/HND/Degree in Electrical/Electronic Engineering (or demonstrable equivalent experience).
- Recognised electrical/safety training aligned to site requirements (varies by operator).
- Vendor training/certification (beneficial): major VMS/ACS/IDS platforms used in the sector.
- Security vetting/clearance: Enhanced BPSS & SC clearances required.
