Location: Blackburn

Job Type: Contract Length: 12 months + Rate: £600-£650 per day INSIDE IR35

Security Clearance required - can start on BPSS then moving to SC

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.

Role purpose:

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.
  • Alarm monitoring integration: SOC/ARC interfaces, incident response workflows.
  • Power and resilience: UPS, battery autonomy, dual feeds, segregation, surge protection, earthing/bonding.
  • Networked security infrastructure: structured cabling, fibre, PoE, network segmentation, time sync, secure remote access patterns (as governed).

Key responsibilities:

  1. Concept and requirements engineering: 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. Define interface requirements with OT/IT, building systems, fire systems and operational processes.
  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.
