The Enterprise Application Support (EAS) organization provides critical application support across the ITP and ECS lines of business, ensuring enterprise platforms are reliable, scalable, and operationally resilient.
As a Principal Application Support Engineer (SRE Lead), you will play a pivotal role in safeguarding the stability and readiness of mission‑critical systems. This is a hands‑on, senior individual contributor role with deep ownership of production reliability and operational risk.
You will act as a reliability authority across the delivery lifecycle—driving the adoption of Site Reliability Engineering (SRE) best practices, influencing system design through non‑functional requirements (NFRs), strengthening observability and resiliency, and leading response during critical production events. Through close partnership with application delivery, infrastructure, security, and risk teams, you will help reduce incidents, improve mean time to restore service (MTTR), and enable confident production releases.

• Partner with delivery teams to champion non‑functional requirements (NFRs) from design through production
• Drive the design and evolution of reliable, resilient, and scalable system architectures
• Influence redundancy, fault tolerance, and disaster recovery strategies
• Provide design recommendations that enable automated recovery and minimize manual intervention
• Develop and maintain application recovery runbooks to improve recovery consistency and reduce downtime
• Design and implement comprehensive monitoring and observability solutions.
• Define actionable alerts and establish Service Level Indicators (SLIs) and Service Level Objectives (SLOs).

• Partner with security teams to ensure systems are resilient against cyber threats.
• Incorporate security best practices into operational and reliability designs.
• Collaborate with IT Embedded Risk Managers to identify and remediate operational and reliability risks.
• Lead operational readiness reviews with EAS L2 support teams at key project milestones.
• Identify operational risks and gaps; validate NFRs in UAT environments to ensure production readiness.
• Proactively assess capacity needs and plan for future growth.
• Implement scaling strategies to support high‑load and peak usage scenarios.
• Analyze performance metrics, identify bottlenecks, and drive performance optimization initiatives.
• Define and track KPIs to demonstrate operational improvements and system reliability.
