• Testing and Analysis: Conduct impact and sensitivity testing to provide analytical support to the credit team.
• Documentation: Create detailed documentation using Markdown and Docusaurus to ensure clarity and compliance.
• Technical Support: Offer guidance and support to credit modellers as needed.

What We're Looking For:

• Python Expertise: Some ex Python developer, with familiarity in FastAPI and modern development tools (e.g., pydantic, uv, ruff).
• Cloud Platforms: Familiarity with cloud computing platforms such as Azure, AWS, or GCP.
• SQL Knowledge: Strong understanding of SQL; knowledge of ORM is a plus.
• Azure Proficiency: Experience with Azure Container Apps and Azure Functions.
• Container Knowledge: Understanding of Docker and its application in containerisation.
