Adobe Experience Manager (AEM) Edge Delivery Services (EDS) . This is a unique reliability engineering opportunity focused on

CDN and edge reliability, web performance, observability, release engineering, incident management, resilience, and third-party integrations

rather than traditional server administration. You will help establish the reliability practice from the ground up and work closely with

platform vendors, cybersecurity, network/CDN, privacy, production support, engineering, and enterprise technology teams

in a highly regulated environment. In this role,

web performance is treated as a core product requirement . You will define measurable performance objectives, monitor real-user experience, manage performance budgets, and drive improvements across the entire web delivery stack. Key Responsibilities :

Own the operational health and monitoring of the public-facing web platform across

CDN, edge configuration, DNS, TLS certificates, caching, cache invalidation, WAF, bot management, and third-party integrations . Monitor critical customer-facing journeys and identify reliability or performance issues before they significantly impact users. Build and maintain

external synthetic monitoring

across key templates, languages, regions, and customer journeys. Develop automated smoke tests and dependency checks to validate critical interfaces following production changes. Participate in an

on-call rotation

and serve as a senior technical escalation point for customer-facing incidents. Lead incident response, troubleshooting, stakeholder communication, root-cause analysis, and post-incident reviews. Establish and maintain vendor escalation procedures, including severity mapping, escalation contacts, evidence collection, SLA/OLA tracking, and incident follow-up. Create diagnostics and operational runbooks for edge-specific incidents such as

content publishing failures, cache invalidation issues, DNS/TLS problems, WAF issues, and content-source outages . Change & Release Reliability

Design and operate change-management processes for a

Git-based production environment . Establish reliable controls around Git-based deployments while maintaining enterprise change-management and audit requirements. Own CI/CD quality and security controls, including

branch protection, required checks, linting, automated testing, performance validation, and secret scanning . Establish repeatable

rollback, revert, republish, and cache-purge procedures . Rehearse recovery procedures and measure recovery time to ensure rollback processes are operationally proven. Support high-volume content publishing with appropriate

approval, attribution, traceability, and audit evidence . Represent the platform through change governance and release-management processes. Maintain release documentation, freeze calendars, deployment procedures, and operational readiness requirements. Business Continuity & Resilience

Define and test recovery strategies for the

content source, Git repository, CDN configuration, and edge platform configuration . Manage CDN and edge configuration using

Infrastructure as Code (IaC) / Configuration as Code

principles wherever practical. Define

Recovery Time Objectives (RTO)

and

Recovery Point Objectives (RPO)

in partnership with business and technology stakeholders. Plan and execute disaster recovery,



resilience, and operational continuity exercises. DNS issues Cache invalidation failures WAF misconfiguration Repository issues or compromise Maintain operational resilience documentation and evidence required for a regulated enterprise technology environment. Identify platform dependencies and maintain appropriate recovery and exit/portability strategies for critical third-party services. Reliability & Web Performance Engineering

Define and maintain

Service Level Indicators (SLIs), Service Level Objectives (SLOs), and error budgets

for availability, reliability, and web performance. Establish

Core Web Vitals

targets and performance thresholds across key page templates and customer journeys. Build an observability practice using

Real User Monitoring (RUM), CDN/edge logs, enterprise SIEM, metrics, and external synthetic monitoring . Establish governance around third-party scripts and tags, including performance measurement, approval processes, and performance budgets. Monitor CDN usage, asset storage, media delivery, egress, and other platform-related capacity and cost considerations. Identify trends and recurring reliability issues and drive preventative engineering improvements. Produce reliability, availability, and web-performance reporting for technology, risk, and business leadership. Compliance & Operational Controls

Establish operational controls and evidence for a

vendor-operated / SaaS-based technology platform . Support

SIEM log ingestion, retention, access reviews, repository controls, configuration management, and audit evidence . Partner with cybersecurity, privacy, compliance, risk, and third-party risk teams.

Support technology control assessments and provide operational evidence for audits and regulatory reviews. What You'll Build :

This is a

build-and-run SRE role . During the initial phase, you will help establish and mature the reliability engineering practice, including: Real User Monitoring (RUM)

and Core Web Vitals dashboards CDN and edge log ingestion and alerting External synthetic monitoring CDN and edge configuration as code Reliability and operational runbooks Incident response and escalation playbooks Vendor escalation and operational support processes Git-based change and release controls Automated smoke and dependency testing Disaster recovery and resilience procedures Rehearsed rollback and recovery processes SLOs, SLIs, error budgets, and reliability reporting Operational readiness and compliance evidence Required Qualifications :

Strong hands-on experience operating

high-traffic, public-facing websites behind an enterprise CDN . Deep expertise in

CDN configuration and edge delivery , including: Origin behavior Caching strategies Cache invalidation TLS/SSL DNS Routing and traffic behavior Strong experience with

logs, metrics, Real User Monitoring, synthetic monitoring, SLIs, SLOs, and error budgets . Robust experience with

Git-based development and release engineering . Hands-on experience with

CI/CD pipelines and production deployment controls . Experience with

Infrastructure as Code / Configuration as Code . Proven experience supporting or leading

customer-facing incident management and incident response . Strong understanding of root-cause analysis, post-incident reviews, operational readiness, and continuous reliability improvement. Experience working within enterprise

change management, audit, access-control, compliance, and third-party risk processes . Ability to work effectively across engineering, security, infrastructure, vendors, production support, and business stakeholders. Preferred Qualifications :

Experience with enterprise SIEM and log-management platforms. Experience defining and reporting reliability and performance metrics to senior technology stakeholders. What This Role Is Not :

Operating-system patching Container orchestration Traditional application-server administration Traditional database administration Server-based infrastructure operations Traditional compute capacity planning The underlying delivery infrastructure is largely operated by the platform provider. Your focus will instead be on the

reliability surface owned by the enterprise , including CDN/edge configuration, content delivery, integrations, release processes, observability, performance, resilience, and operational controls. Why Join This Team?

This is an opportunity to help define reliability engineering for a

modern, serverless/edge-based enterprise web platform

rather than simply operating an existing infrastructure environment. Build a reliability practice from the ground up Work with modern

CDN and edge technologies Own enterprise-grade

web performance and Core Web Vitals Establish SRE principles including

SLOs, SLIs, and error budgets Build observability around

RUM, synthetics, and edge telemetry Design resilience and disaster-recovery practices Work directly with technology vendors and enterprise stakeholders Influence how reliability, performance, and operational excellence are implemented across a high-visibility public platform If you are an experienced

SRE / Reliability Engineer

with deep CDN, edge, web-performance, observability, and incident-management experience, we would like to hear from you.
