ROLE PROFILE:

The Senior Manager - Reliability Engineering is accountable for the reliability, resilience, and operational effectiveness of critical enterprise applications and platforms throughout the service lifecycle.

The role will drive the evolution of the L2/SRE function from reactive production support towards proactive reliability engineering, using automation, observability, operational learning, and strong engineering partnerships to reduce toil, incidents, and operational risk.

Working across engineering, product, infrastructure, security, and support, the role will promote shared ownership of production reliability and ensure services are continuously improved to meet agreed levels of availability, performance, resilience, and customer experience.

What you'll be doing

Lead the L2/SRE function and its continuous improvement, with accountability for improving service reliability, resilience, operational efficiency, and engineering maturity.

Lead, mentor, and develop a high-performing L2/SRE team, fostering accountability, technical capability, operational excellence, and continuous improvement.

Define and mature Service Level Objectives (SLOs), Service Level Indicators (SLIs), and error budgets to support clear, data-led reliability and engineering decisions.

Reduce operational toil through automation, improved tooling, self-service capabilities, and simplification of repetitive support activities.

Establish strong observability and alerting standards across logging, metrics, tracing, dashboards, and telemetry to improve detection, diagnosis, and recovery.

Define operational readiness standards, ensuring services are supportable, resilient, appropriately monitored, well documented, and have clear recovery and escalation procedures before entering production.

Lead effective Incident Management within L2/SRE, including response, escalation, post-incident review, and identification of recurring issues. Partner with L3 on Problem Management and RCA, ensuring corrective actions and reliability improvements are tracked through to completion.

Champion strong ITSM practices and operational hygiene across Incident, Problem, Change, service ownership, documentation, and continuous improvement.

Oversee proportionate, risk-based Change Management and approval processes, ensuring changes are appropriately assessed, dependencies and conflicts are understood, implementation and rollback plans are robust, and higher-risk activity receives the right level of scrutiny while avoiding unnecessary overhead for well-understood, low-risk change.

Partner with L3 engineering and other technology teams to ensure production learnings, recurring incidents, support .
