About the Role
An excellent opportunity exists for a proactive and detail-oriented Security Design Engineer to join a specialist team focused on Electrical Transmission & Gas Transmission Sites across the UK mainland. This role is pivotal in delivering high-quality, compliant security designs — alongside associated electrical designs (LV & ELV) — from concept to completion.

You will be responsible for producing detailed security system designs (Door Access, CCTV, Power Fence) and electrical designs (LV & ELV) that meet rigorous legislative, customer, and technical standards. The position offers a "cradle to grave" project involvement, from initial site survey through to handover, providing significant variety and technical challenge. This is a fantastic opportunity to work on critical national infrastructure within a supportive and forward-thinking team.

Key Responsibilities (including but not limited to):

• Produce detailed security system designs (Door Access, CCTV, Power Fence) in line with all relevant standards and specifications.

• Produce detailed electrical designs (LV & ELV) to support the security systems.

• Carry out site surveys on Electrical Transmission & Gas Transmission sites across the UK.

• Develop concept and detailed design packages for both internal and external review.

• Follow your designs through to 3rd party approval, construction, commissioning, and project handover.

• Produce essential technical documentation, including block diagrams, single line diagrams, wiring schematics, and cable/load/material schedules.

• Proactively manage design change control and identify project risks, devising contingency plans.

• Attend and contribute to HAZID/HAZCON and Design Assurance & Review meetings.

• Collaborate effectively with the Design, Construction, and Project Management teams, as well as P6 Planners.

• Mentor and develop new and existing engineers within the team.

• Ensure all company management systems and processes are adhered to.

Requirements

• Proven experience as a Security Design Engineer, ideally within the power transmission, utilities, or critical infrastructure sectors.

• Experience designing security systems such as Door Access, CCTV, and Power Fence.

• Experience designing Low Voltage (LV) and Extra Low Voltage (ELV) AC systems, AC UPS, and DC systems.

• Proficient in Amtech (or ElectricalOM) and AutoCAD.

• Ability to create 2D drawings (General Arrangement/Site Layouts) and ideally 3D BIM/Revit models.

• Demonstrable ability to produce detailed technical schedules (Cable, Load, Material, Equipment).

• Excellent communication, analytical, and problem-solving skills.

• Full, valid UK driving licence with a willingness to travel to sites across the UK mainland.

Desirable Skills & Qualifications:

• Previous Security Design experience for UK Transmission (GT or ET).

• Previous EC&I/Security installation experience (hands-on).

• Experience with REVIT BIM, Hazardous Area Design (ATEX/IECEx/Ex12), and DSEAR.

• 18th Edition Wiring Regulations (2382) & Level 4 Design and Verification (2396).

• Minimum HNC in Electrical Engineering (Ideally BEng).

• Working towards or achieved Chartered or Incorporated Engineer status.

• National Grid Person – Substation and/or EUSR – SHEA Gas certifications.

Why Join?

• Impactful Work: Play a key role in delivering essential security and electrical infrastructure for the UK's energy networks.

• Autonomy: Take ownership of your projects from cradle to grave, seeing your designs come to life.

• Support: Join a national organisation with a strong reputation, backed by a collaborative technical and operational team.

• Development: Ongoing training and development opportunities to help you progress your career and achieve professional accreditation.
