- Curiosity and hacker mentality — you learn new tools quickly and aren’t afraid to dive deep.

**Bonus**:
- Experience with **AWS Bedrock** for building and scaling **generative AI** applications.
- Experience with **LLM frameworks** (**LangGraph**, **Guardrails**, **LangChain**, etc.) or building multi-agent or autonomous workflows.
- Background in financial risk, real-time decisioning, or fraud detection systems.
