About Zuno

Zuno is the cutting-edge technology platform powering the success of home heating and cooling experts, BOXT. Zuno is scaling for significant growth by continually developing its proprietary tech stack to empower both our installers and the homeowners of brands such as E.ON Next and BOXT.

Our platform manages the end-to-end installation process for a complete range of modern home energy solutions—from high-efficiency boilers and air conditioning to heat pumps, solar panels, battery storage, and EV chargers. No matter what we are installing, our ethos remains the same: we use technology to make buying, installing and maintaining products an efficient, stress-free, seamless experience for our users.

Every year millions of people come to our site to get a fixed-price quote. We’ve installed over 200,000 products so far, while establishing a network of more than 15,000 professionally accredited installers.

Our revolutionary platform is market-leading. And we’ve got the supporters to shout about it. We’re backed by Brookfield and work in partnership with some of the world’s most famous household names.

The role

We are looking for a hands-on mid-level DevOps engineer to help build and run the platform our business depends on. You will not just keep the lights on; you will work with others to shape how we build, deploy and operate our infrastructure. The foundations are in place, but we are growing and evolving, so there is plenty to still define; you will be a key member of the team driving this forward.

You will write infrastructure as code, own pipelines, and work directly with product engineers to make shipping software fast, safe and secure. You will be trusted to pick up work without being told, diagnose incidents and create solutions that fit the problem.

Responsibilities

Infrastructure and automation

• Builds and maintains our AWS infrastructure as code, treating infrastructure with the same care as application code — reviewed, tested and versioned.
• Optimise our platform and containerised workloads on ECS and Fargate, including scaling, cost and service health.
• Automates repeat work rather than absorbing it, removing toil from the team instead of quietly living with it.
• Owns and improves our CircleCI and GitHub Actions pipelines so builds, tests and deployments are quick and predictive.
• Writes and maintains runbooks so operational knowledge sits with the team rather than with one person.

Reliability and observability

• Set up and tune monitoring and alerting in New Relic so problems are spotted before customers raise them, and so alerts mean something when they fire.
• Takes part in incident response, helps establish root cause, and sees follow-up fixes through to completion rather than leaving them on a list.
