- Work with APIs from OpenAI, Google Cloud, Azure, and others to create functional pipelines.
- Support rapid prototyping and deployment of AI features in close coordination with product and automation teams.
- Evaluation & Instrumentation
- Define key performance metrics (quality, reliability, usage patterns).
- Collaborate with data engineering to log, analyze, and visualize LLM performance.
- Implement feedback loops to continuously optimize prompt and agent behavior.
- Enablement & Documentation
- Provide tooling and guidance to business users and product teams for prompt-based workflows.
- Contribute to internal AI playbooks and best practices around prompt usage and API integration.
Requirements
- 3 - 5 years of experience in AI/ML, NLP applications, or full-stack product development
- Hands-on experience with OpenAI APIs, Google Cloud Vertex/Gemini, or similar platforms
- Strong experience with prompt engineering and LLM evaluation methods
