Senior Physical Security Design Engineer

Working alongside the Physical Security Technical Design Lead and multidisciplinary engineering teams, you will take ownership of the technical development of security designs from concept through detailed design, ensuring solutions are compliant, coordinated and aligned with client requirements, industry standards and operational objectives.

The successful candidate will act as a technical authority for physical security systems, supporting project delivery through design development, technical reviews, coordination with other engineering disciplines and mentoring of junior engineers. This role requires extensive experience in designing integrated physical security systems within complex-built environments, particularly data centres and other critical infrastructure.

Responsibilities

Lead the technical design and coordination of integrated physical security systems including CCTV, Access Control, Perimeter Intrusion Detection Systems (PIDS), Intrusion Detection Systems (IDS), Intercom and Security Management Systems.

Produce and review security design documentation including design reports, technical specifications, equipment schedules, calculations, schematics, layouts and detailed construction drawings.

Develop security strategies and engineering solutions that satisfy client operational requirements while complying with relevant standards, legislation and project objectives.

Coordinate physical security designs with ICT, Electrical, Mechanical, Architectural, Civil and Structural disciplines to ensure fully integrated design solutions.

Participate in technical workshops with clients, operators, architects, contractors and specialist vendors to develop and validate security design requirements.

Undertake technical assessments including Threat, Vulnerability and Risk Assessments (TVRA), security zoning studies, design risk assessments and engineering option appraisals.

Review vendor proposals, technical submissions and contractor deliverables to ensure compliance with project specifications and design intent.

Prepare equipment schedules, cable schedules, device layouts and system architecture diagrams suitable for construction and procurement.

Ensure designs comply with relevant British, European and International Standards together with applicable client design standards and regulatory requirements.

Undertake design coordination reviews using BIM/Revit, Bluebeam and other digital engineering tools.

Carry out design QA/QC reviews and technical assurance activities in accordance with the company's Quality Management System.

Support commissioning planning, witness testing and technical issue resolution during construction and project delivery.

Provide technical mentoring and guidance to graduate and junior engineers, supporting continuous professional development within the team.

Maintain awareness of emerging technologies, industry trends and best practice in physical security design, particularly within hyperscale and colocation data centre environments.

Support continuous improvement initiatives through the development of design standards, templates, technical guidance documents and lessons learned.
