Along with financial services knowledge and the ability to identify wider business impacts, risks, and opportunities to make connections across key outputs and processes, you’ll have the desire to understand the business requirements and limitations, and expertise to make relevant suggestions. You’ll have an understanding of how to present data and insights for key stakeholders and experience using programming and scripting languages such as Python and Bash.

Additionally, you’ll need:

• An understanding of the capabilities and experience with LLMs and their APIs, and the ability to read and understand a large documentation base, as well as contribute to it
• Strong software engineering, systems architecture, and unit testing capabilities and experience using pipeline tools such as Apache Airflow, Amazon SageMaker, or similar
• Familiarity with SQL and experience with AWS or other cloud providers
