SRE

We are looking for an experienced Site Reliability Engineer to own the reliability, availability, security, and performance of a high-traffic, customer-facing banking website operating on a vendor-managed Adobe platform.

This role focuses on CDN and edge reliability, web application security, browser performance, observability, incident management, and release engineering rather than traditional infrastructure or server administration.

The successful candidate will work closely with Adobe, Information Security, Network and CDN teams, Privacy, Production Support, and full-stack development teams to establish and operate a comprehensive reliability engineering practice.

This is a build-and-run role, with significant responsibility for implementing monitoring, automation, operational controls, disaster recovery, and performance management practices.

Key Responsibilities

1. Application Reliability & Incident Management

• Own end-to-end monitoring of CDN, edge configuration, DNS, TLS certificates, caching, cache invalidation, and third-party integrations.
• Build and maintain external synthetic monitoring across website templates and supported languages.
• Develop automated smoke tests for dependent interfaces and integrations.
• Lead incident response for customer-facing issues and participate in the shared on-call rotation.
• Manage vendor escalations, including Adobe incident coordination, severity mapping, evidence collection, and SLA follow-ups.
• Troubleshoot content publishing issues, cache invalidation failures, and content-source outages.
• Develop incident playbooks, operational runbooks, and procedures that enable service desk teams to diagnose common issues.

2. Change & Release Management

• Establish a release management process that aligns Git-based deployments and continuous content publishing with enterprise change-control requirements.
• Maintain CI/CD pipelines with branch protection, mandatory checks, linting, performance testing, and secret-scanning controls.
• Implement and rehearse rollback procedures, including code reverts, content republishing, and CDN cache purging.
• Ensure production content changes have appropriate approval records, attribution, and audit trails.
• Participate in Change Advisory Board (CAB) activities and manage release notes and production freeze calendars.

3. Business Continuity & Disaster Recovery

• Develop and execute disaster recovery plans for content sources, Git repositories, and CDN/edge configurations.
• Manage CDN and edge configuration as code to support consistent deployment and recovery.
• Define and validate Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) with business stakeholders.
• Conduct resilience testing for certificate expiry, cache invalidation failures, WAF misconfiguration, content-source outages, and repository compromise.
• Maintain operational resilience documentation, recovery evidence, and platform exit and portability plans.

4. Reliability & Web Performance Engineering

• Define and manage Service Level Objectives (SLOs) for website availability and page performance.
• Establish Core Web Vitals thresholds, performance dashboards, alerting, and error-budget reporting.
• Implement Real User Monitoring (RUM), external synthetic monitoring, and CDN access-log ingestion into enterprise SIEM platforms.
• Investigate page-performance regressions using browser waterfalls and front-end telemetry.
• Govern third-party scripts and tags, measure their performance impact, and establish approval processes and performance budgets.
• Monitor CDN egress, asset storage, media delivery, and associated service consumption and costs.
• Deliver reliability and performance reports to technology, business, and risk stakeholders.

5. Security, Compliance & Operational Controls

• Establish monitoring and evidence collection for controls on vendor-managed platforms.
• Manage log ingestion, retention requirements, access reviews, and audit evidence across repositories, Adobe administration tools, content sources, and CDN platforms.
• Collaborate with Information Security, Privacy, Operational Risk, and Third-Party Risk teams.
• Support regulatory and internal compliance requirements related to technology risk, cybersecurity, and operational resilience.
• Maintain accurate configuration management records, support models, and operational ownership documentation.

Mandatory Skills & Experience

• Substantial hands-on experience operating high-traffic public websites behind enterprise CDNs.
• Strong expertise in CDN configuration, including origin configuration, caching, cache invalidation, edge logic, TLS, and DNS.
• Practical experience with Web Application Firewalls (WAF), including false-positive tuning and production policy validation.
• Experience with bot management, including protecting applications while allowing legitimate search-engine crawlers.
• Strong understanding of SRE principles, including SLOs, SLIs, error budgets, incident management, and service reliability reporting.
• Hands-on experience with web performance engineering, Core Web Vitals, browser rendering, network waterfalls, and JavaScript performance analysis.
• Working knowledge of JavaScript and CSS to troubleshoot client-side reliability and performance issues.
• Experience implementing observability using logs, real-user telemetry, and synthetic monitoring.
• Strong Git-based release engineering and CI/CD experience, including infrastructure and configuration as code.
• Proven experience in production incident response, root cause analysis, rollback planning, and recovery procedures.
• Experience working within regulated environments with change management, audit evidence, access controls, and third-party risk requirements.
• Strong communication and stakeholder-management skills, including coordination with external technology vendors.

Nice-to-Have Skills

• Hands-on experience with Akamai or Cloudflare.
• Adobe Experience Manager (AEM), particularly Edge Delivery Services and Assets as a Cloud Service.
• Experience supporting financial services, banking, or other regulated industries.
• Experience operating vendor-managed or SaaS-based platforms.
• Experience supporting bilingual English and French websites.
• Working knowledge of accessibility and SEO considerations related to website reliability and performance.
• Automation and scripting experience using Python, Java, or JavaScript
