Site Reliability Engineer (SRE)

London (Hybrid - 2-8 days per month in office)

£50,000 per annum

Clear progression to Mid-Level SRE within 18 months

We're working with a growing, engineering‑led organisation looking to hire a Site Reliability Engineer who enjoys solving real platform problems through automation—not just firefighting tickets.

This role blends hands‑on engineering with platform ownership. You'll spend your time split between:

• Supporting developers with broken builds and deployments (40%)
• Designing and building automation, CI/CD pipelines, and Terraform infrastructure (60%)

You'll act as the automation backbone of the platform—reducing manual effort, improving reliability, and enabling engineering teams to move faster.

• Debug failing builds, deployments, and CI/CD pipelines
• Provide Tier 2/3 support via Slack, tickets, and pairing sessions
• Take ownership of incidents, ensuring reliable and timely resolution

• Design, build, and optimise CI/CD pipelines (Git Hub Actions, Jenkins, Git Lab CI)
• Develop and maintain Terraform modules for infrastructure‑as‑code
• Build automation tools (CLI tools, scripts, Git Hub Apps, self‑service tooling)
• Own observability: dashboards, alerts, monitoring, and runbooks
• Continuously improve platform processes and reduce operational toil

• 2‑3 years in Dev Ops, SRE, or Platform Engineering
• Strong Linux troubleshooting and systems knowledge
• Proven experience with Terraform (module design, not just usage)
• CI/CD experience (Git Hub Actions, Git Lab CI, Jenkins)
• Ability to write production‑quality code in Python or Bash
• Solid networking fundamentals (DNS, load balancers, CDNs)
• Experience with observability tools (New Relic, Datadog, Prometheus, Grafana)
• Comfortable participating in on‑call rotations
• Experience using AI tools (e.g. ChatGPT, Copilot, Cursor) to enhance productivity

• Go, Ansible, or configuration management experience
• Experience working with multiple CDNs (Cloud Front, Fastly, Cloudflare)

• You're a proactive problem‑solver who automates rather than repeats
• You communicate clearly with both technical and non‑technical stakeholders
• You stay calm under pressure and take ownership during incidents
• You care about clean, maintainable, production‑quality code
• You actively use AI tools to improve how you build and debug systems

• £50,000 salary
• Genuine ownership of CI/CD and platform automation
• Direct collaboration with the Head of Technology
• Clear progression to mid‑level SRE within 18 months
• Learning budget and dedicated development time

This is not a ticket‑driven support role. You'll be a key technical contributor shaping how the platform operates—working alongside engineers who code and influencing real infrastructure and tooling decisions.
