London, United Kingdom Leap29 Digital Full time

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.
