Support reconciliation efforts by comparing and tracing data across multiple platforms.

Application and Integration Support:

Collaborate with software engineers, solution architects, product teams, and business stakeholders to understand system functionality and technical requirements.
Analyze REST APIs, service interactions, message flows, and integration patterns.
Assist in impact assessments for enhancements, upgrades, and application modernization initiatives.
Support testing efforts by defining test scenarios and validating expected data outcomes.
Participate in troubleshooting efforts related to application integrations and data issues.

Documentation and Process Improvement:

Data flow diagrams
Interface specifications
System dependency maps

Strong expertise in SQL with demonstrated ability to write complex queries, joins, aggregations, subqueries, Common Table Expressions (CTEs), and performance analysis.
Experience analyzing relational database structures and data models.
Proven ability to document complex system architectures and data flows.
Experience working with multi-tier application environments, including:
Databases

Preferred Qualifications:

Knowledge of microservices and service-oriented architectures.
Experience with cloud platforms such as Azure, AWS, or Google Cloud.
Familiarity with data lineage, metadata management, and enterprise architecture concepts.
Experience with diagramming and documentation tools such as Visio, Draw.io, or Enterprise Architect.

Trace data from source databases through backend and middleware layers to end-user applications.
Build trusted relationships with engineering, product, and business teams.
Translate technical concepts into clear documentation and actionable insights.
