Job description

Our client, an established developer and operator of hyperscale data centres, is seeking a Senior Design Manager to shape the control systems, networks and connectivity infrastructure that underpin mission‑critical facilities.

This is an opportunity to take technical ownership across new developments, expansions and retrofit projects, influencing design decisions from concept through construction, commissioning and operational handover. Working closely with engineering leadership, you will help deliver secure, resilient and scalable infrastructure that meets demanding client and operational requirements.

The Role:

As the design authority for BMS, CCCS, telecommunications and associated ICT and OT/IT infrastructure, you will lead design development, govern technical standards and coordinate complex system interfaces. You will work with clients, consultants, contractors, system integrators and telecommunications providers to translate requirements into practical, integrated engineering solutions.

Key Responsibilities

Design Leadership and Engineering Governance

• Lead design development from concept and detailed design through issued‑for‑construction and as‑built documentation.
• Review and approve technical specifications, drawings, control philosophies, network architectures and interface documents.
• Partner with engineering leadership to align designs with project objectives, performance standards and resilience requirements.
• Manage technical risks, promote design consistency and support standardisation across projects.

BMS, CCCS and Controls Integration

• Define and validate system architectures, topologies and integration strategies across electrical, mechanical and fire protection systems.
• Review control sequences, logic diagrams, alarm strategies, interlocks and setpoints.
• Ensure designs support integrated systems testing and operational readiness.
• Provide technical oversight during Factory Acceptance Testing, Site Acceptance Testing and Integrated Systems Testing, maintaining alignment with approved design intent.

ICT and Network Infrastructure

• Lead ICT infrastructure design supporting BMS, CCCS, data centre infrastructure management, maintenance management, analytics and reporting platforms.
• Develop OT and enterprise network architectures covering segmentation, redundancy, firewalls and high availability.
• Oversee inside and outside plant infrastructure design, including secured trunking, cable containment, fibre backbones, pathways, terminations, labelling and security zoning.
• Incorporate capacity planning and future expansion requirements into infrastructure designs.
• Coordinate with architectural, civil, structural and MEP teams to deliver constructible designs and resolve clashes.

Telecommunications and Client Connectivity

• Serve as the project design team’s primary technical interface for telecommunications matters.
• Work with carriers to define connectivity requirements, route diversity and resilience strategies.
• Coordinate points of entry, meet‑me rooms, external duct banks and campus connectivity.
• Integrate telecommunications requirements into fibre routing, containment and secured infrastructure designs.
• Support timely carrier service delivery and commissioning while accommodating carrier neutrality and future capacity growth.

Client Integration and Site Networks

• Translate client technical and connectivity requirements into compliant, deliverable designs.
• Define and govern secure, scalable API integrations with BMS and CCCS platforms.
• Establish corporate and campus Wi‑Fi design standards covering coverage, redundancy, cybersecurity and IT integration.
• Ensure site networks support project delivery, commissioning and operations while maintaining appropriate segregation from OT systems.

Cybersecurity and Technical Assurance

• Embed secure‑by‑design principles across network and control system designs, including access controls, remote connectivity and logging.
• Ensure compliance with applicable OT cybersecurity standards, network segmentation requirements and audit expectations.
• Maintain accurate design documentation, network diagrams, interface control documents and change records.

Project Delivery and Operational Handover

• Coordinate internal and external stakeholders to maintain alignment on scope, standards and client requirements.
• Support procurement, tender evaluations and technical clarifications.
• Communicate complex engineering matters clearly to technical and non‑technical audiences.
• Ensure designs support maintainability, monitoring and future scalability.
• Facilitate structured handover to operations through clear design intent documentation and knowledge transfer.
