Core Responsibilities

Primary Functions

Act as the primary application owner for assigned business systems, managing configuration, release updates, and end-to-end lifecycle activities to ensure stability, performance, and alignment with business objectives.
Gather, document, and validate detailed functional and non-functional requirements from cross-functional stakeholders, transforming business needs into technical specifications, user stories, acceptance criteria, and process flows.
Lead or participate in application implementation projects including requirements analysis, solution design, configuration, data mapping, migration planning, and cutover activities to deliver on-time and within scope.
Design, build, and maintain integrations between internal systems, cloud services, and third-party applications using RESTful APIs, SOAP, middleware (e.g., MuleSoft, Dell Boomi), or ETL tools; create and maintain integration documentation and data flow diagrams.
Troubleshoot and resolve complex production incidents through root cause analysis, corrective actions, and permanent fixes; coordinate with development, infrastructure, and vendor teams to minimize business impact.
Perform SQL queries, stored procedure reviews, and database troubleshooting for performance tuning, data reconciliation, and reporting accuracy across relational databases (e.g., SQL Server, Oracle, PostgreSQL).
Manage application change requests, enhancements, and configuration updates using formal change control processes (ITIL-based), assessing risk, ROI, and rollback strategies.
Plan, coordinate, and execute system upgrades and patch deployments; create runbooks, test plans, and rollback procedures; validate successful deployments in production.
Create and maintain comprehensive application documentation including process flows, configuration guides, integration maps, data dictionaries, runbooks, and operational support procedures to support knowledge transfer and audits.
Design and execute end-to-end testing strategies: unit tests, system integration testing (SIT), user acceptance testing (UAT), regression testing, and performance validation to ensure quality and fit-for-purpose releases.
Provide second- and third-line support for escalated incidents and service requests, manage ticket triage, SLA adherence, and provide timely status updates to stakeholders.
Coordinate with security, compliance, and audit teams to ensure applications meet regulatory and internal control requirements, including access control reviews, encryption, logging, and vulnerability remediation.

Work with vendors and managed service providers for licensing, support contracts, escalations, and technical collaboration; manage vendor deliverables and act as the technical liaison.
Develop and deliver training materials, conduct user training sessions, and create self-service documentation to improve user adoption and reduce recurring support requests.
Optimize business processes by proposing automation, configuration changes, or integration improvements that reduce manual work and increase throughput and accuracy.
Validate and reconcile data during migrations or integrations, resolving mapping issues, data quality problems, and ensuring referential integrity across systems.
Drive continuous improvement by analyzing support metrics, incident trends, and user feedback to propose enhancements, efficiency gains, and modernization opportunities.
Participate in Agile ceremonies (sprint planning, backlog grooming, demos) and collaborate with product owners, scrum masters, QA, and engineering teams to deliver iterative value.
Support disaster recovery and business continuity planning for critical applications, participating in failover testing and operational readiness exercises.
