Original job description

Senior Site Reliability Engineer - AEM - Content Delivery Network

Toronto- 4 Days WFO

ABOUT THE ROLE

1. Application Support & Incident Management

Own end-to-end monitoring of the controlled surface: CDN and edge configuration, DNS, certificates, cache and invalidation health, and every third-party integration on the page – Search, Consent Management, Analytics, Personalization and AI services and many more to come.

Build and run synthetic monitoring from outside the bank network, per template, per language, because internal-only monitoring cannot see the CDN, DNS and certificate failures this architecture is most exposed to.

Run smoke testing of dependent interfaces on every change and maintain the automation packs that do it.

Participate in the shared on-call rotation as the platform’s subject-matter escalation, and lead incident management for customer-facing events.

Own the vendor's escalation path: severity mapping between vendor and internal incident scales, named contacts, evidence capture, and holding the vendor to its commitment during an event.

Handle a class of incident that does not exist on traditional platforms – content published but not visible, invalidation failure, and authoring-source outages – and make those diagnosable by the service desk rather than by you.

2. Change and Release Reliability

Design and operate change management for the platform where the Git repository is production: reconcile a merge-to-main deployment model with change control, so that every production change carries an approved record with stalling delivery.

Own the release pipeline as a production control – branch protection, required checks, lint, performance, and secret-screening gates – and the evidence that they are enforced.

Own rollback: revert, republish and purge, rehearsed end to end with a measured recovery time and a named authority who can call it without convening a meeting.

Treat content publishing as a routine process: hundreds of production changes made by content authors, needing approval evidence, attribution and retention trail.

Represent the platform at change advisory board, and own the freeze calendar interaction and release notes.

3. Business Continuity and Resilience

Own the recovery obligation. The vendor operates delivery resiliently, but customers restore their own content from source version history rather than vendor backups – so the content source, the Git repository and the CDN configuration are the recovery surface, each needing a tested restore.

Hold CDN and edge configuration as code so that a lost or corrupted property is a redeploy rather than an outage with no runbook.

Define RTO and RPO with the business against the application criticality tier, document the DR exercise plan, and execute the testing – including failure modes you can actually cause: certificate expiry, invalidation failure, WAF misconfiguration, content source unavailability, and repository compromise.

Maintain the operational resilience evidence a regulator expects for a material third-party technology arrangement, and keep the platform exit and portability plan current.

4. Reliability & Performance Engineering

Set and defend service level objectives for both availability and page performance. Define Core Web Vitals thresholds per template, run them on an error budget, and report against them.

Build the observability practice from the telemetry that exists; real user monitoring on the production domains, CDN access logs streamed to enterprise SIEM as the log source of record, and external synthetics. There is no origin server log – designing around that constraint is part of the job.

Own third-party scripts and tag governance as a reliability control. Tags are the dominant cause of performance regressions and are added by teams outside engineering change control; you will define the approval route, measure each tag’s cost and enforce the budget.

Own capacity and cost where they still exist: CDN egress, asset storage and processing, media delivery and any hosted APIs behind the page. Capacity planning here is a financial operations discipline, not a server-sized one.

Publish the reliability and performance reporting that the business, risk and technology leadership use.

5. Compliance and Control Evidence

Evidence controls on a platform the organization does not operate – which is harder than evidencing your own, and is where a meaningful share of the role’s effort sits.

Own log ingestion into SIEM with the agreed retention, access recertification across the repository, admin console, content source and CDN, and the audit evidence pack.

Support privacy, operational risks, control assessment and third-party risk processes with operational evidence and maintain alignment to regulatory expectations for technology, cyber and third-party risks.

Keep the configuration management database, support model and assignment groups accurate as the platform estate grows.

WHAT WILL YOU DO?

This is a build-then-run role. Roughly half of the first year is establishing a reliability practice that does not exist yet.

The observability stack: Real User Monitoring, Core Web Vitals dashboards and alerting, CDN log ingestion, and external synthetics.

CDN and Edge configuration as Code, with a tested restore.

The operations runbook, incident playbook, operational level agreement and vendor escalation matrix.

The change model that reconciles Git-based deployments and continuous content publishing with change controls.

The first disaster recovery exercise and the first rehearsed, measured rollback.

Service level objectives agreed with the business, and the reporting that holds the platform to them.

WHAT DO YOU NEED TO SUCCEED?

Must have

Substantial hands-on experience operating a high-traffic public website behind an enterprise content delivery network. Depth in CDN configuration – origin and cache behaviour, invalidation, edge logic, TLS and DNS – is the single most important qualification. Akamai and Cloudflare experience is an advantage.

Practical web application firewall experience, including tuning false positives against production-like traffic before enforcement, and bot management that protects the site without blocking the crawlers you need.

A real observability practice: defining service level objectives and error budgets, and building monitoring from log, real-user and synthetic sources rather than from an agent on a server.

Web performance engineering – Core Web Vitals, load and rendering behaviour, and the ability to read a waterfall and attribute a regression to a specific script.

Comfortable with front-end technology: This platform ships JavaScript and CSS to the browser with no server tier; you cannot reason about its reliability without reading and understanding it.

Git-based release engineering and CI/CD as a production control, including infrastructure and configuration as code.

Incident command on customer-facing services, and the discipline to produce evidence during an event, not after it.

Working effectively in a regulated environment – change control, audit evidence, access management and third-party risk – without treating it as an obstacle.

Nice-to-have

Experience operating a vendor-run or SaaS-delivered platform, where reliability means instrumenting, escalating and holding a supplier accountable rather than fixing the tier yourself.

Adobe Experience Manager exposure, particularly Edge Delivery Services and Assets as a Cloud Service.

Financial services or another regulated sector.

Bilingual delivery – operating a site that must meet the same standard in English and French.

Accessibility and Search Engine Optimization literacy sufficient to recognize when a reliability decision creates a compliance or discoverability problem.

Automation in Python, Java or JavaScript, and a preference for encoding a runbook rather than writing one.
