- Develop and maintain AI-powered systems, including RAG pipelines that integrate structured and unstructured business data into production workflows.
- Improve the reliability, observability, and robustness of both AI-driven and non-AI systems as the platform scales.
- Design and implement automation and RPA-style workflows to reduce manual effort and improve operational efficiency.
- Optimize application performance, system latency, APIs, and overall availability.
- Apply best practices for security, with particular focus on handling sensitive financial and business data.
