Senior Site Reliability Engineer (SRE) – Contract – UK-Based

Are you a proven Site Reliability Engineer with a passion for driving operational excellence and helping teams mature their SRE practices? We are working with a highly regarded cloud consultancy on a short-term assignment supporting a major digital services project.

This is a UK-based contract with the potential for occasional visits to a London office. We’re seeking a true SRE expert, not a DevOps engineer with partial SRE exposure. You’ll need to hit the ground running and bring deep hands-on experience across all facets of SRE—advisory, technical implementation, and mentoring.

What You'll Do

  • Assess the current reliability maturity of a complex platform and guide improvements.
  • Identify gaps in process, tooling, and mindset, and lead practical interventions.
  • Raise the capabilities of an existing team, introducing best practices and scalable runbooks.
  • Take ownership of system reliability, observability, and incident response readiness.
  • Collaborate with developers to implement automation, resilience strategies, and SLOs.
  • Ensure robust post-mortem processes are in place and conduct root cause analysis.
  • Drive continual improvement, from tooling to team processes and infrastructure reliability.

    • Key Requirements

  • Must have held dedicated Site Reliability Engineering roles, not DevOps with SRE exposure.
  • Able to work independently with zero handholding from day one.
  • Experience working with clients in advisory/consultancy roles preferred.
  • Strong understanding of observability, incident management, runbooks, and SLIs/SLOs.
  • Solid coding background (e.g., Python, C#, Java) and experience working across modern infrastructure.
  • Expertise in tools like Terraform, Prometheus, Grafana, Datadog, Azure/AWS, Kubernetes, and CICD platforms.
  • Clear communicator who can align technical delivery with business goals.

    • Project Details

  • Start: ASAP
  • Duration: Short-term
  • Location: UK-based contractor with a few onsite visits to London
  • Rate: Competitive – senior-level budget available
  • Note: This role is not for a third-party client but is directly supporting an internal initiative at a global tech consultancy.

    • If you’re a seasoned SRE ready to take on a high-impact role and immediately add value, we’d love to hear from you.
