1️⃣ Chief Technology Officer | Industrial AI | UK Remote | Lead autonomous optimization through a Series C scale phase

The Opportunity

numi has been exclusively retained to partner with a pioneering technology company supporting energy-intensive and mission-critical operations. Operating from on-premises environments through to the cloud, our client sits at the critical intersection of operational technology (OT) and information technology (IT).

The next three years represent a deliberate scale phase, evolving from validated deployments to a robust, repeatable and scalable application architecture. We are seeking a strategic and hands-on technology leader to join their Executive Leadership Team and drive that journey.

The incoming CTO will define how this product vision is delivered at scale, with resilience, repeatability, and architectural clarity. This role carries full accountability for technology strategy, engineering execution, and driving the ambition to scale from early revenue toward £50m+.

What You’ll Be Doing

• Define and execute the technology strategy, architecture, and engineering vision across OT and IT domains.
• Architect scalable, repeatable deployment models capable of supporting significant commercial growth.
• Navigate and modernize existing infrastructure, resolving technical debt across AWS, Kubernetes, and Docker environments.
• Deploy AI and distributed systems into real-world operational environments.
• Drive the technical transition toward more agentic AI and autonomous optimization capabilities.
• Strengthen internal engineering discipline and processes as the business matures.
• Remain hands-on with system design and coding when required.
