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:

Create and maintain comprehensive technical documentation, including:
Data flow diagrams
Interface specifications
System dependency maps
Data dictionaries
Process workflows
Application inventories

Identify opportunities to improve data transparency, operational efficiency, and system observability.

Required Qualifications:

5 plus years of experience as a Systems Analyst, Technical Analyst, Business Systems Analyst, or related role.
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

APIs
Front-end applications
Strong analytical and problem-solving skills.
Excellent verbal and written communication skills.

Preferred Qualifications:

Experience with API analysis and testing tools such as Postman, Bruno or Swagger/OpenAPI.
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.
Exposure to ETL processes and data integration technologies.
Experience supporting Agile development teams.
Understanding of application logging, monitoring, and observability tools.

Technical Skills

Required:

Technical documentation and process modeling

Preferred:

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.
Leverage advanced SQL skills to investigate issues, validate system behavior, and support data-driven decision making.

This role is ideal for a technically curious analyst who enjoys uncovering how systems work, mapping complex data journeys, and using data analysis to solve business and technology challenges.
