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 is an ideal opportunity for someone with 2–3 years of DevOps, Platform Engineering or SRE experience who wants to take ownership of CI/CD, infrastructure-as-code, and platform tooling while continuing to build production-grade coding skills. The OpportunityThis 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. Key ResponsibilitiesDeveloper Support & Troubleshooting (40%)
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
Platform Engineering & Automation (60%)
Design, build, and optimise CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI)
Develop and maintain Terraform modules for infrastructure-as-code
Build automation tools (CLI tools, scripts, GitHub Apps, self-service tooling)
Own observability: dashboards, alerts, monitoring, and runbooks
Continuously improve platform processes and reduce operational toil
What We’re Looking ForEssential Skills & Experience
2–3 years in DevOps, SRE, or Platform Engineering
Strong Linux troubleshooting and systems knowledge
Proven experience with Terraform (module design, not just usage)
CI/CD experience (GitHub Actions, GitLab CI, Jenkins)
Ability to write production-quality code in Python or Bash
Solid networking fundamentals (DNS, load balancers, CDNs)
Experience with observability tools (NewRelic, Datadog, Prometheus, Grafana)
Comfortable participating in on-call rotations
Experience using AI tools (e.g. ChatGPT, Copilot, Cursor) to enhance productivity
Desirable
Go, Ansible, or configuration management experience
Experience working with multiple CDNs (CloudFront, Fastly, Cloudflare)
About You
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
What’s On Offer
£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
Why Apply?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.
