This is a hands-on application development and modernization role requiring strong Python coding skills and extensive experience integrating applications with databases.

- Convert, rewrite, or replace Oracle SQL and PL/SQL logic to support Snowflake based application workflows
- Review and remediate dependencies on Oracle stored procedures
- Read and update selected C# components that interact with Oracle databases, queries, and stored procedures
- Troubleshoot application defects, database connectivity issues, SQL errors, performance problems, and production incidents
- Create and execute unit, integration, regression, reconciliation, and data validation tests
- Validate application results following migration to ensure data accuracy and continuity of business critical processes
- Support Power BI reporting migrations from Oracle data sources to Snowflake where required
- Participate in code reviews, technical discussions, migration planning, release activities, and production readiness reviews
- Document application changes, database interfaces, testing results, known issues, and operational procedures
- Collaborate with developers, Technology teams, risk professionals, and technical stakeholders throughout the modernization lifecycle
REQUIREMENTS:
- 5 or more years of professional software or application development experience
- Strong hands-on Python development experience, including enhancing, testing, debugging, and supporting production applications

- Advanced SQL skills with experience writing, troubleshooting, and optimizing complex application queries
- Strong experience integrating Python applications with relational databases
- Experience maintaining application modules, database connectivity components, and data access layers
- Strong Oracle experience, including Oracle SQL, PL/SQL, stored procedures, and database driven applications
- Experience analyzing, modifying, converting, or replacing stored procedure logic
- Experience with Snowflake application connectivity and SQL development, or experience with another modern cloud database platform
- Experience supporting a database migration, application modernization, or application repointing initiative
- Experience debugging production applications and resolving database integration issues
- Experience with application testing, regression testing, reconciliation, or data validation
- Ability to read, understand, and update C# application code
- Experience with source control, code reviews, and collaborative development practices
- Strong analytical, troubleshooting, organizational, and communication skills
- Degree in Computer Science, Engineering, Mathematics, Statistics, Finance, or a related discipline, or equivalent experience
