What You'll Do

The Senior Site Reliability Engineer is responsible for running the engineering capability behind a defined area of reliability across the organisation. The role works across multiple SRE disciplines including infrastructure, cloud, observability, automation, identity, security, and network operations, applying engineering thinking to reduce operational toil, improve resilience, and embed reliability and governance into delivery and operational workflows.

The role drives engineering quality and consistency within its scope of responsibility, contributes to wider engineering standards, and helps shape how reliability is delivered across the organisation. It builds reusable patterns, mentors engineers, and provides senior engineering input across a wider set of stakeholders.

The ideal candidate is a senior practitioner who is comfortable operating across multiple domains, balances delivery with mentorship, and can articulate engineering trade-offs clearly to both technical and non-technical audiences.

Core responsibilities

• Run and continuously improve the reliability engineering systems within scope, including automation, pipelines, observability, and operational tooling.
• Design and implement engineering solutions that eliminate operational toil at scale and embed reliability into delivery workflows.
• Help shape engineering standards, patterns, and reusable frameworks across the SRE practice.
• Lead the engineering response to complex incidents within scope, drive systemic remediation, and contribute to post-incident learning.
• Mentor and coach less senior engineers across reliability engineering, automation, observability, and SRE principles.
• Drive cross-team collaboration with engineering, platform, and operations functions to embed reliability and governance through engineering controls.
• Communicate engineering status, risks, and recommendations clearly to senior stakeholders and leadership forums.
• Contribute to monthly operational reviews with structured metrics on service health, ingestion or pipeline performance, automation coverage, and improvement progress.

What You'll Bring

• 5–8 years of experience in Site Reliability Engineering, Platform Engineering, or related operational engineering disciplines.
• Strong hands-on experience across multiple SRE domains, including cloud, automation, observability, and CI/CD.
• Demonstrated experience designing and implementing automation and reliability solutions at scale.
• Deep knowledge of at least one cloud platform (AWS or Azure), including networking, identity, and observability primitives.
• Experience with Infrastructure-as-Code (e.g. Terraform) and CI/CD pipelines.
• Strong scripting experience (e.g. Python).
• Experience leading incident response and driving systemic improvement.
• Strong stakeholder engagement and technical communication skills.
• Deep hands-on experience with one or more enterprise observability platforms (e.g. Splunk, Datadog).
• Proven experience designing and operating telemetry pipelines, ingestion controls, and observability cost management.
• Proven experience designing signals (SLIs, SLOs, synthetic checks, alerts) and ops automation triggered from those signals.
• Experience driving SLO/SLI practices across multiple teams.
• Deep hands-on experience operating cloud infrastructure across at least two of AWS, Azure, GCP, or Alibaba Cloud.
• Proven experience designing reusable IaC patterns and landing zone components across cloud providers.
• Strong working knowledge of cloud networking, account management, identity primitives, and policy enforcement across providers.
• Experience driving cloud platform engineering standards and governance across multiple teams.
• Deep hands-on experience with identity platforms (e.g. Entra ID) and secrets management (e.g. HashiCorp Vault).
• Proven experience designing OIDC, workload identity, and dynamic credential patterns.
• Experience driving Zero Trust and least-privilege adoption across multiple teams.
• Deep hands-on experience with security tooling embedded in CI/CD pipelines.
• Proven experience designing policy-as-code controls and secure-by-default patterns.
• Experience driving secure engineering adoption across multiple teams.
• Deep hands-on experience with hybrid and cloud network architectures.
• Proven experience designing automated network controls through IaC.
• Experience driving Zero Trust segmentation and network observability adoption.

Preferred qualifications

• Experience working within a federated, multi-cloud, or large enterprise environment.
• Familiarity with containerisation (Docker) and orchestration (Kubernetes).
• Experience with secrets management tooling (e.g. HashiCorp Vault).
• Cloud certification at professional level.
• Experience with policy-as-code tooling (e.g. OPA, Sentinel).
• Experience contributing to engineering communities of practice.
• Experience with AIOps, noise reduction, and event correlation.
• Experience with event-driven ops automation platforms (e.g. ServiceNow, PagerDuty, custom workflows).
• Ability to lead complex observability platform incidents and capacity reviews.
• Experience with cloud FinOps, cost engineering, and chargeback tooling.
• Hands-on experience with Alibaba Cloud platform architecture.
• Experience with cloud policy-as-code tools (e.g. AWS Service Control Policies, Azure Policy, OPA).
• Strong understanding of identity-related security risks and mitigations.
• Strong understanding of common security risks and mitigations across the SDLC.
• Strong understanding of network reliability, observability, and security patterns.

Who You'll Work With

• Hybrid or on-site work model.
• Operates as a senior individual contributor with mentorship and cross-team influence.
• Expected to participate in on-call rotation and lead incident response.
• Occasional travel may be required for team or stakeholder engagement.
