Job Summary

We are seeking a highly skilled and proactive Adobe Site Reliability Engineer (SRE) specializing in CDN and Web Performance to join our client's agile team.

Job Overview

This role focuses on CDN and edge reliability, website performance, monitoring, incident management, release engineering, and operational resilience. The successful candidate will help establish reliability practices for a vendor-managed platform supporting high-traffic public-facing digital experiences.

WHAT YOU WILL OWN

1. Application Support & Incident Management

- Own end-to-end monitoring of the TCS-controlled environment, including CDN and edge configuration, DNS, certificates, caching, cache invalidation, and third-party integrations such as search, consent management, analytics, personalization, and AI services.
- Build and operate synthetic monitoring outside the corporate network, covering individual templates and languages to identify CDN, DNS, and certificate failures.
- Run smoke tests for dependent interfaces after every change and maintain automated testing suites.
- Participate in the shared on-call rotation as the platform subject-matter expert and lead incident management for customer-facing events.
- Manage vendor escalation procedures with Adobe, including incident severity mapping, escalation contacts, evidence collection, and vendor accountability.
- Troubleshoot platform-specific incidents, including published content that is not visible, cache invalidation failures, and content authoring source outages.



Improve diagnostic procedures so the service desk can identify and resolve common issues.

2. Change and Release Reliability

- Design and manage change control for a Git-based production deployment model, ensuring every production change has an approved record without unnecessarily delaying delivery.
- Own the release pipeline as a production control, including branch protection, required checks, linting, performance testing, secret scanning, and supporting evidence.
- Own rollback procedures, including code reverts, content republishing, and cache purging. Rehearse recovery procedures, measure recovery times, and establish clear decision-making authority.
- Establish controls for routine content publishing, ensuring production changes made by content authors have approval evidence, attribution, and retention records.
- Represent the platform at change advisory board meetings and manage release freeze calendars and release notes.

3. Business Continuity and Resilience

- Own TCS's recovery responsibilities. While Adobe operates the delivery infrastructure, TCS must maintain recovery capabilities for content sources, Git repositories, and CDN configurations.
- Manage CDN and edge configuration as code so that lost or corrupted configurations can be restored through controlled redeployment.
- Define Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs)



with the business, document disaster recovery plans, and execute recovery testing.
- Test realistic failure scenarios, including certificate expiry, cache invalidation failures, WAF misconfiguration, content source unavailability, and repository compromise.
- Maintain operational resilience evidence for third-party technology arrangements, including platform exit and portability plans.

4. Reliability & Performance Engineering

- Establish and maintain service level objectives for availability and page performance. Define Core Web Vitals thresholds for each template, manage error budgets, and report on performance.
- Build an observability practice using Real User Monitoring (RUM), CDN access logs integrated with enterprise SIEM, and external synthetic monitoring.
- Develop monitoring and troubleshooting procedures that account for the absence of traditional origin server logs.
- Manage third-party scripts and tag governance as reliability controls. Measure individual tags' performance impact, establish approval processes, and enforce performance budgets.
- Manage CDN data transfer, asset storage and processing, media delivery, and any TCS-hosted APIs supporting the website.
- Produce reliability and performance reports for business, risk, and technology leadership.

5. Compliance and Control Evidence

- Establish and document operational controls for a platform that TCS does not operate directly.
- Manage SIEM log ingestion and retention, access reviews across repositories, Adobe Admin Console, content sources, and CDN platforms, and maintain audit evidence.
- Support privacy, operational
