Infrastructure & Security Engineer — 18+ years across hyperscale data centres, critical infrastructure, cloud, and physical security. London / Barcelona.
A Kiwi infrastructure engineer who’s built, secured, and run systems from hyperscale data centres to a 47-foot sailboat. Looking for roles where architecture meets implementation.
I design and deliver infrastructure that works at scale. 18+ years across hyperscale data centres (Meta EMEA), critical national infrastructure (London Stock Exchange Group), and full-stack IT management for enterprise clients. I’m most useful where architecture meets implementation — someone has to actually make it run.
Today I advise through my consultancy TechSquad London, building SaaS products and developer tooling alongside security and cloud architecture work. I’m looking for the right permanent or contract role where I can own technical direction, not get pulled into endless BAU support.
I live on a 47-foot Hanse 470e sailing yacht in Barcelona — she’s got her own Omada WiFi, Pepwave 5G bonding, and a Raspberry Pi monitoring power and bilge. A floating micro-data centre. Living aboard has taught me more about systems thinking and resource management than any data centre ever could.
18 years designing and deploying secure network architectures across enterprise, data centre, and maritime environments. Cisco switching, OSPF routing, SD-WAN multi-site bonding, Cloudflare Zero Trust, and structured cabling including fibre.

Gavin Singh UK Services Manager at Meta (M.C. Dean)
Scott kept our studio running through some of the most intense production cycles. When you’re a 3D design studio with tight deadlines, you can’t afford IT downtime. He designed our network, managed the render farm, and handled everything from security to end-user support. A rare mix of deep technical knowledge and genuine people skills.
