Job description

The Data Centre Design & Infrastructure Strategy Engineer defines how the bank's data centres are designed, expanded and modernized. The role sets design standards, challenges existing architecture, builds costed options, and makes the financial case for infrastructure investment across more than 30 facilities in 12 countries. The role works closely with network architecture, hosting, sourcing, external engineering consultants and colocation providers, and presents recommendations directly to senior technology leadership.

Key Responsibilities:

Design standards

• Define and maintain the standard data centre design classification — what a site should look like based on its network architecture and purpose, including base provisioning per rack type, power density assumptions, and structured cabling standards.

Site studies and uplift strategy

• Lead deep-dive assessments of existing sites covering power and cooling capacity, demand history, device footprint and rationalization opportunities.
• Commission and interpret engineering feasibility studies and translate the findings into a clear recommendation.

Expansion options and business cases

• Build costed option sets — reclaim existing footprint, add racks, or take new whitespace — with the capital, one-time and recurring cost impact of each. Present trade-offs plainly and recommend a path.

Architecture challenge

• Decide what goes into the rack: device placement, redundancy, pod versus legacy connectivity, cabling media, and uplink standards.
• Expect to question existing network and rack design where it no longer serves the business.

Vendor and partner engagement

• Negotiate power uplifts, containment modifications and cage expansion with colocation providers.
• Manage engineering consultants and cabling vendors through survey, quotation and delivery.
• Familiarity with Uptime Institute Tier standards, ASHRAE thermal guidelines and local APAC regulatory requirements
• Experience with DCIM tooling and capacity forecasting platforms
• Exposure to regulated financial services environments
• Relevant certification such as CDCP or equivalent

Required Skills & Experience

• Substantial experience in data centre design, engineering or infrastructure strategy, ideally in a multi-site regional role
• Strong grounding in data centre M&E: UPS, PDU, CRAC/AHU, cooling capacity, containment, three-phase power distribution
• Network architecture literacy — comfortable reading switch configurations, counting ports, and understanding spine/leaf and pod-based designs well enough to challenge them
• Proven ability to build costed options and business cases, and present them to senior stakeholders
• Track record negotiating with colocation providers, landlords and engineering consultants

Preferred Qualifications

• Background in network architecture and engineering, facilities engineering or infrastructure planning
• Experience supporting large-scale or regulated enterprise environments (e.g. financial institutions)
