[Hiring] Site Reliability Engineer @Hozah

Role Description

You will be Hozah’s first Site Reliability Engineer, and the person who owns how our platform runs. Our parking and payments systems take money from motorists (pay by web, Autopay, kiosks) and pay it on to landowners, and our ANPR enforcement runs around the clock. Those paths have to stay up and stay correct. You own the platform they run on:

• GKE and Kubernetes
• Helm
• Terraform for our Google Cloud organisation and projects
• SOPS-encrypted secrets
• Semaphore CI/CD pipelines
• Temporal for the ANPR workflows
• Postgres

You also own the reliability practice around it:

• Uptime targets
• Alerting
• On-call
• Incident response
• Cost of running it all

This is a new role. We are hiring a senior engineer to own cloud cost, uptime and on-call, set up a proper incident process, and make the platform something engineers trust. You’ll support all of Hozah’s engineering teams, and you’ll work daily with their engineers. The data engineer owns the data warehouse; you’ll work with them, and infrastructure for data still goes through engineering. This is a newly created role with no direct reports.

Qualifications

• You’ve owned production reliability for a Kubernetes-based platform (GKE, EKS or AKS) in the last 12 to 24 months.
• You write and maintain infrastructure as code, ideally Terraform.
• You’ve built CI/CD pipelines with safe release: rollbacks and promotion between environments.
• You’ve cut cloud cost with a measured result and kept it down.
• You’ve set up or rebuilt on-call and incident response in a small team.
• You’ve built observability and service level objectives that changed what got fixed.
• You work with product engineers without becoming a ticket queue.
• You use AI tools sensibly for operations work.
• You’re comfortable setting your own priorities in a fast-moving SME.
• Experience of Google Cloud itself, Temporal, Semaphore or SOPS is welcome, but none of it is required.

Requirements

• Own the production platform: GKE and Kubernetes, Helm, Postgres, Temporal and the environments (staging and production).
• Own uptime and reliability; agree service level objectives for the money-moving and enforcement paths.
• Own on-call: the rota, the runbooks and the incident process.
• Own observability across Cloud Monitoring, Logging and Trace.
• Own our infrastructure as code; everything changes through Terraform and CI.
• Own the Semaphore CI/CD pipelines and safe release: rollbacks, progressive rollout and promotion between environments.
• Own cloud cost; know what we spend and why, reduce it with measured results.
• Work with product engineers as a partner and not a ticket queue.

Benefits

• Fully remote working within the UK, or a London office next to East Croydon Station if you prefer to be in.
• Sole ownership of the platform and reliability practice, reporting directly to the CTO.
• The chance to build Hozah’s reliability function from a working base as we scale.
• A strong, high performing culture, with genuine influence over how that culture develops as Hozah grows.
• A fully refurbished, modern office, right next to East Croydon Station, open to you whenever you want it (with a fully stocked kitchen, offering free breakfast, lunch and drinks!).
