- Ability to critically evaluate AI-generated outputs, with strong debugging and problem-solving skills to validate correctness.
Preferred Requirements
- Bachelor’s or Master’s degree in Computer Science, Machine Learning, or a related field. Equivalent practical experience considered in lieu of degree.
- Familiarity with AI tools and frameworks like AWS Bedrock, Langchain, vector databases, or similar AI orchestration technologies.
- Experience with machine learning workflows and large language models (LLMs).
- Familiarity with orchestrating ML-driven actions in high-complexity or high-throughput environments.
