Hamish Bray

I am a people-first Chief Technology Officer and Head of Engineering with over 20 years of experience driving architectural vision, technical governance and high-velocity engineering delivery for complex enterprise platforms. Having spent over a decade navigating large-scale stakeholder landscapes in enterprise IT consulting, I specialise in bridging intricate technical execution with commercial business strategy and product roadmap ownership. Throughout my career I have focused on transforming legacy application landscapes into optimised, unified delivery models. My background spans the full technology lifecycle; from partnering with CEO and sales executives on multi-million dollar transformations and leading interactive UX/product discovery workshops, to architecting multi-region cloud platforms and establishing modern engineering standards. As CTO / Head of Engineering at Lumiant, an enterprise wealthtech SaaS platform, I served on the executive leadership team owning global technology and platform strategy. I spearheaded a ground-up strategic re-architecture of our core software environment, transitioning a fragmented legacy setup into a high-performance, multi-region Python and TypeScript monorepo on AWS. My focus is heavily centred on Developer Experience (DevEx) and operational efficiency; I pioneered the deployment of Rust-based validation tooling (Ruff, Biome) and git-tracked AI workflows to automate standards enforcement and compress cycle times while maintaining strict data compliance. Beyond technical governance, my leadership philosophy is deeply rooted in engineering culture and organisational stability. I break down operational silos, manage R&D capital generation workflows and build high-retention, geographically distributed teams; maintaining a 90%+ team retention rate across scale-ups and corporate consulting environments. I partner directly with Founders, CEOs and executive boards to build resilient platform architectures, drive practical AI capability and cultivate high-trust, high-velocity engineering cultures built for sustainable scale.
