Design Engineer (Communications, CCTV and PAVA)

The Design Engineer will be responsible for the design and technical assurance of backbone and access communications networks (DWDM, SDH, PDH, MPLS), CCTV and PAVA systems, with a particular focus on Nokia-based telecommunications infrastructure. They will take solutions from concept through detailed design and into construction/as-built, working closely with project, operations and commissioning teams to deliver robust, resilient and compliant systems., * Develop detailed designs for transmission and IP networks including DWDM, SDH, PDH and MPLS-based architectures (core, distribution and access layers).

• Design and document solutions using predominantly Nokia communications equipment (e.g. edge/core routers, switches, SDH/DWDM platforms), including chassis layouts, card population, port allocations and resilience schemes.
• Produce detailed designs for associated CCTV and PAVA systems, ensuring correct network integration, QoS and bandwidth provision.
• Prepare network topologies, IP plans, VLAN schemas, routing designs, clocking/synchronisation schemes and protection mechanisms (e.g. ring, 1+1, MSP).
• Produce drawings, schematics, rack layouts, patching schedules, cable schedules and design calculations to required standards.
• Interpret client requirements, specifications and standards to develop compliant, cost-effective and scalable designs.
• Undertake or review site surveys to validate design assumptions for space, power, environmental and cabling/containment routes.
• Produce design documentation including design reports, equipment lists/BoMs, configuration templates and test/acceptance input.
• Coordinate designs with other disciplines (IT, security, electrical, civil, signalling/building services as applicable).
• Provide technical support to installation and commissioning teams, resolving design queries and supporting factory/site acceptance testing.
• Contribute to design reviews, risk/HAZOP workshops and value-engineering exercises.
• Ensure all designs align with relevant standards, cyber/security requirements and client governance processes.

Do you have experience in MPLS?, * Strong experience as a communications / transmission Design Engineer with hands-on exposure to DWDM, SDH, PDH and MPLS networks.

• Proven background designing solutions with Nokia communications platforms (e.g. IP/MPLS routers, switches, optical transport/SDH equipment).
• Good understanding of IP networking (routing, switching, MPLS, QoS, multicast where relevant) and their application to CCTV and PAVA backhaul.
• Experience integrating CCTV and PAVA systems over managed transmission/IP networks including bandwidth and latency considerations.
• Proficiency in preparing network design artefacts: high-level and low-level designs, interface specifications, addressing plans, rack layouts and patch schedules.
• Good working knowledge of resiliency and protection schemes for carrier-grade or mission-critical networks.
• Competent user of CAD tools for drawings and standard office tools for reports, schedules and calculations.
• Ability to work through the full design lifecycle (concept, scheme, detailed, IFC, as-built) on live projects.
• Strong written and verbal communication skills, with the ability to explain complex technical solutions to both technical and non-technical stakeholders.

Desirable

• Experience in transport, rail, utilities, critical national infrastructure or large campus/public-space environments.
• Familiarity with other vendors' transmission/IP equipment and ability to interface with multi-vendor environments.
• Understanding of cyber-security principles for operational networks, including segregation and remote access controls.
• Knowledge of related systems such as access control, intrusion detection, help points and passenger/public information systems.
• Relevant engineering qualification (HNC/HND or degree) in Telecommunications, Electrical/Electronic Engineering or similar.
• Professional membership or working towards (e.g. IET) and relevant vendor certifications (e.g. Nokia network certifications).
