The opportunity

The Site Reliability Engineering Lead (SREL) is accountable for the reliability, health, and operational sustainability of a broader portfolio of applications, data pipelines, platforms, and services. The role proactively identifies systemic and recurring risks and leads or directs technical initiatives, including the design and implementation of monitoring, automation, operational support tooling, and selected code to reduce incidents, manual intervention, cost, and operational burden. The SREL serves as a senior technical advisor and escalation point, translating complex issues, options, risks, and trade‑offs into transparent business language for stakeholders.

Who you'll work with

Reports to: Director, Product / Data Enablement

Works closely with: Site Reliability Engineering Specialists, Product Engineering Leads (PEL), Data Solutions Leads, Data Platform Leads, Enterprise Architecture, Security, Technology Services, business stakeholders, and third‑party vendors.

Collaborates regularly with Product Engineering, Data Solutions, and Data Platform teams to support smooth transitions from build to run and to identify and resolve recurring reliability and supportability issues. Depending on the nature and complexity of the change, the Lead may implement or direct selected code, configuration, automation, or process changes through development, testing, release, and post‑implementation validation, or work with the appropriate team to secure prioritization, ownership, and completion.

Partners with Technology Services teams including Infrastructure, Cloud, and Platform teams to troubleshoot complex and cross‑service issues and to design and implement, or direct the implementation of, observability, automation, resilience,



and operational support tooling that improves service quality and reduces operational burden. Frequent communication with business stakeholders is required to provide transparency into system health, incident status, systemic risks, and improvement priorities, adapting the level of technical detail to the audience, including senior business stakeholders when required.

What you'll do

Service Reliability Strategy and Ownership

Own and continuously improve the reliability, supportability, and operational efficiency of a broad portfolio of applications, data pipelines, platforms, and services including availability, latency, performance, resilience, and cross‑service dependencies.

Define and govern Service Level Availability (SLAs), and related reliability metrics for the portfolio in accordance with enterprise standards and business expectations and drive changes where performance or operational risk warrants.

Establish and maintain a prioritized reliability roadmap incorporating application, data pipeline and service health plans balancing business criticality, operational risk, support effort, capacity, cost, and technology priorities.

Use deep technical and trend analysis across incidents, alerts, service performance, capacity, storage, cost,



and support effort to identify systemic failure modes and lead cross‑service improvement initiatives through implementation and outcome validation.

Operational Excellence

Lead response to high‑impact, complex, or cross‑service incidents, coordinating technical teams and ensuring timely audience‑appropriate stakeholder communication.

Drive Root Cause Analysis and problem‑management activities beyond minimum process requirements, identify systemic technical, architectural, monitoring, process, and organizational contributing factors, and challenge recurring issues that have become normalized as operational support work.

Ensure corrective or preventive actions are completed and validated through permanent remediation, automated mitigation, or appropriately authorized risk acceptance.

Own the end‑to‑end resolution of selected recurring production defects and supportability issues. Where appropriate, implement or direct code, configuration, scripting, automation, and process changes through technical review, testing, release, and post‑implementation validation, and drive changes requiring Product or Data ownership through prioritization and completion.

Lead portfolio‑level capacity, performance, resilience, and recovery analysis and improve Mean Time to Detect (MTTD) and Mean Time to Restore through monitoring, diagnostics, runbooks, automation, and operational learning.

Contribute to Disaster Recovery (DR) and resilience plans and participate in recovery testing.

Observability & Automation

Design and implement, or direct the implementation of, portfolio‑wide monitoring, observability, event‑management, diagnostic, automation, self‑healing, and operational support tools that improve support effectiveness and service quality.
