We are seeking an experienced Site Reliability Engineer (SRE) to join our Group Technology Team in Milton Keynes.
Connells X is Connells Group Technology’s internal developer platform, built on Microsoft Azure.
It simplifies cloud hosting, embeds security and compliance by default, and enables a frictionless developer experience.
As part of the team building and operating this platform, you will play a hands‑on role in ensuring it is reliable, scalable, and observable.
You will help establish and mature SRE practices, focusing on
- Monitoring and observability
- Reliability testing and capacity planning
- Toil reduction
We offer a hybrid working arrangement with one day per week in our Milton Keynes office.
Key Responsibilities
- Support teams using Connells X and respond to incidents in a structured, blameless way
- Investigate root causes and drive post‑incident actions to completion
- Define SLIs, contribute to SLOs, and monitor error budgets
- Build dashboards, alerts, and runbooks to improve visibility
- Automate repetitive tasks to reduce operational toil
- Collaborate with cross‑functional teams to enhance reliability and observability
- Support performance testing and capacity planning
- Proactively identify and prioritise reliability improvements
Experience & Skills Required
- Hands‑on experience with Azure Monitoring (Application Insights, Alerts, Action Groups)
- Strong knowledge of Open Telemetry (including Kubernetes)
- Experience with Terraform and Git Hub Actions
- Ability to define SLIs/SLOs and manage error budgets
- Incident response and post‑incident review experience
- Familiarity with Docker and Kubernetes
- Strong communication and documentation skills
- Working knowledge of . NET/C# and React/Next JS
- Experience with cloud cost optimisation
- Knowledge of Azure networking (DNS, VNets, Firewalls)
- Understanding of security frameworks (e. g. ISO 27002, NIST CSF)
About You
You may come from SRE, Dev Ops, platform engineering, or operations backgrounds.
What matters is hands‑on experience running production systems, managing incidents, creating runbooks and automating repetitive work.
The focus is on identifying root causes and systemic issues, reducing manual toil through automation, and maintaining reliability by applying SRE principles and using data‑driven metrics (SLIs/SLOs).
You understand reliability is about balance, not perfection, and can make data‑driven trade‑offs between stability and delivery.
You are curious, collaborative, and take shared responsibility for system reliability.
