About the Role
GenAI models are improving very quickly, and one of our goals is to make them capable of addressing specialized questions and achieving complex reasoning skills. If you join the platform as an AI Tutor in Coding, you’ll have the opportunity to collaborate on these projects.
Although every project is unique, you might typically:
- Design prompt variations and evaluation cases to surface edge behaviors, failure modes, and performance regressions.
- Collaborate with engineers to align prompts with project constraints, APIs, and CI/CD workflows.
- Iterate on prompt strategies using test results and human feedback to improve reliability and reduce hallucinations.
- Document prompt patterns, expected outputs, and known limitations to support reuse and handoffs.
How to get started
Simply apply to this post, qualify, and get the chance to contribute to projects aligned with your skills, on your own schedule. From creating training prompts to refining model responses, you’ll help shape the future of AI while ensuring technology benefits everyone.
