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.
- Analyze web performance regressions using browser/network telemetry and identify the specific source of degradation.
- Review browser waterfalls, rendering behavior, network requests, JavaScript execution, CSS, third-party scripts, APIs, and other dependencies.
- 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.
- Maintain accurate configuration management records, support models, ownership, assignment groups, and operational documentation.
- Ensure reliability and operational practices align with enterprise security, regulatory, and third-party risk requirements.
- Support technology control assessments and provide operational evidence for audits and regulatory reviews.
