Senior Site Reliability Engineer
Job Description
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.
