A hyperscale data centre developer and operator with campuses across APAC is hiring a senior OT Solution Architect, based in Australia, where most of its build programme sits.

This is a hands-on OT role. You'll own the architecture for the systems that keep the data halls running: BMS, EPMS, SCADA, DCIM, PLCs and controls, and how they sit on the underlying IT network. You'll also make sure the platforms and vendors chosen meet the organisation's security and governance standards.

It's a senior individual contributor role. You won't run an internal team, but you will direct outsourced specialists, integrators and technology partners, so technical credibility and influence matter more than headcount.

What you'll do

Own the target architecture and standards for data centre OT: BMS, EPMS, SCADA, DCIM, PLCs, controllers and monitoring

Define how OT platforms connect to enterprise IT and the network, with resilience and supportability built in

Assess vendor platforms and appliances, and set requirements for vendor connectivity and remote support

Provide architecture assurance on new builds, expansions and upgrades through design, commissioning and handover

Plan lifecycle,



obsolescence and resilience across OT platforms

Brief senior leaders on OT risk, investment priorities and trade-offs

What they're looking for

Hands-on senior experience with BMS, EPMS, SCADA and OT controls in data centres, critical infrastructure, utilities or industrial environments

Solid underlying IT and networking knowledge: routing, switching, firewalls and remote access

Experience directing vendors and integrators through design, commissioning and handover

OT cyber security knowledge, such as IEC 62443 or segmentation design, and GRC exposure are a plus

Certifications such as GICSP, CCNP or IEC 62443 are helpful

Why it's worth a look

You’ll set the OT architecture standard for a large build programme rather than inherit someone else's

It sits where data centre engineering, controls and IT meet

A newly structured ICT team with a clear plan and investment behind it
