Job description

Senior Site Reliability Engineer (SRE)

We’re partnered with one of the UK’s fastest-growing AI companies, building cloud-native video intelligence products deployed across a rapidly growing fleet of connected devices.

They’re looking for a Senior SRE to own reliability across both their AWS platform and edge infrastructure — combining software engineering, automation and production infrastructure at serious scale.

What You’ll Be Doing

• Build software and tooling to improve the reliability and scalability of production systems


• Own and evolve large-scale AWS & Kubernetes environments


• Build observability, monitoring and telemetry across cloud and edge infrastructure


• Improve deployment, CI/CD and incident response processes


• Automate provisioning and lifecycle management across connected devices


• Identify reliability bottlenecks and engineer them out of the platform


• Improve developer experience through internal tooling and automation

What They’re Looking For

• Strong SRE or software engineering background


• Production coding experience with Python or Go


• Strong Infrastructure-as-Code and automation experience


• Solid understanding of observability, incident management and production reliability


• Edge / IoT experience is a bonus, not essential


• SRE role where you'll actually write software, not just manage infrastructure


• Reliability challenges spanning cloud + thousands of physical devices


• Real-world AI systems with meaningful scale and availability requirements


• Small engineering team with significant ownership and architectural influence


• Strong commercial traction, significant funding and meaningful equity

If you’re an SRE who enjoys building systems rather than babysitting them, this is worth a conversation.
