Prompt & AI Interaction Engineer

About this role

The AI team owns the models inside the product: resume understanding, candidate-to-role matching, and the assistive tooling recruiters use every day.

Design how the product talks to models and how models talk back: prompts, tool definitions, guardrails and the evaluation sets that prove a change was an improvement rather than a vibe.

These models influence who a recruiter sees, which makes fairness a design constraint rather than a review step at the end. Every ranking change is evaluated for differential impact before it ships, and the team has standing authority to stop a launch. The input is genuinely hard — CVs in every format a human can invent, multilingual and code-mixed text, and documents photographed at an angle in bad light.

Primary responsibilities

• Design and maintain the prompts and the interaction patterns behind the assistive features
• Build the evaluation sets that tell you whether a prompt change helped or just felt better
• Handle the failure modes deliberately: hallucination, refusal, prompt injection from a document a user uploaded
• Design what the user sees when the model is uncertain, and make correction easy
• Version prompts like code, with review and rollback

Skills required

Day to day this role works with Python, Writing, LLMs and Evaluation.

• Two or more years working directly with LLMs in a product
• You write well — most of this job is writing precisely
• You build the eval before you tune the prompt
• Two or more years working directly with large language models in a product
• Building evaluation sets that show whether a prompt change helped or just felt better
