Type : Contract

Seeking an experienced SRE / Application Resiliency Engineer to support IPCW migration readiness, with a focus on application resiliency, active/passive validation, disaster recovery, and migration failure/recovery planning.

Key Responsibilities

• Define validation strategies for active/passive applications, including functional validation of passive environments without requiring an unplanned production failover.
• Develop application-level migration failure scenarios, recovery procedures, rollback criteria, and operational runbooks.
• Assess application dependencies, resiliency architecture, DR readiness, and failover/failback behavior.
• Define smoke, synthetic, API, and business-transaction validation for post-migration readiness.
• Validate connectivity and dependencies across DNS, load balancers, firewalls, databases, APIs, and downstream/upstream systems.
• Leverage observability including logs, metrics, traces, health checks, dashboards, and alerts to establish validation evidence.
• Partner with application, SRE, infrastructure, network, database, and migration teams during IPCW planning and execution.

Required Skills

• 8+ years in SRE, Production Engineering, Platform Engineering, or Application Resiliency.
• Strong hands-on experience with active/passive and active/active architectures, DR, HA, failover/failback, RTO/RPO, and resiliency testing.
• Strong understanding of distributed applications, APIs, networking, databases, and application dependency mapping.
• Experience with monitoring/observability tools and automated health/functional validation.
• Scripting/automation experience using Python, Shell, APIs, and CI/CD pipelines.
• Strong troubleshooting skills and ability to work across application and infrastructure teams.

Preferred: Prior experience supporting large-scale data-center/cloud migrations, DR exercises, production cutovers, or mission-critical financial-services applications.
