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.
