DESCRIPTION

We are seeking a Senior Python Application Developer with strong SQL, Oracle, and Snowflake experience to join the Risk Division of a major investment management organization.

The successful candidate will enhance, refactor, test, and support existing applications as database dependencies transition from legacy Oracle environments to Snowflake and Azure Cloud. The work will include identifying Oracle database interactions within application code, updating database connectivity and data access logic, converting Oracle SQL and PL/SQL, remediating stored procedure dependencies, and validating application behaviour following migration.

This is a hands on application development and modernization role requiring strong Python coding skills and extensive experience integrating applications with databases. The primary focus is coding, database querying, application repointing, and production support rather than data engineering or data modelling.

RESPONSIBILITIES

Enhance, refactor, test, and support existing Python applications used by Capital Markets Risk and other Risk teams

Analyze application code to identify Oracle database calls, embedded SQL, stored procedure dependencies, and data access logic

Update Python application components as database integrations transition from Oracle to Snowflake

Write clean, maintainable, modular, and testable Python code for business critical applications

Develop, troubleshoot, and optimize SQL queries used by applications, scheduled processes, and reporting integrations

Update database connection logic, application configurations, queries, and data access components

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

Demonstrated ability to write clean, maintainable, and testable Python code

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

NICE TO HAVE

Experience modernizing Python applications from Oracle to Snowflake

Experience converting Oracle SQL, PL/SQL, or stored procedures for Snowflake

Experience supporting scheduled Python applications, calculation processes, or internal business tools

Azure Cloud or Power BI migration experience

Julia programming experience

Experience with Capital Markets, risk management, investment management, or financial services applications

NOTE: As part of our hiring process, we use AI‑based systems to support initial applicant screening.
