Prompting & AI Agent Research Engineer

Role Overview

We're seeking a Prompting & AI Agent Research Engineer to bring structure and rigor to how we advance our AI. This role sits at the intersection of prompt engineering and applied AI research. You'll design experiments, stay close to emerging research, and turn promising ideas into something testable.

What You Will Do

Design structured experiments, build regression test coverage, create a pipeline of validated improvements, and work with the team to prioritize what gets shipped based on experiment results.

Why It Might Be a Fit

You'll own prompt design across Mia's agent workflows, stay current on prompting research, and prototype new approaches locally. You'll work closely with Product and Engineering teams, translate experiment results into clear recommendations, and build out evaluation templates and frameworks.

Requirements

• 5+ years of experience in a prompting, AI research, or applied AI role
• Advanced degree in a research-oriented field (PhD preferred) - CS, linguistics, cognitive science, stats, or similar
• Real prompt engineering experience - deliberately designing, testing, and improving prompts to change system behavior
• Solid experimental design fundamentals: controls, statistical significance, knowing when a result actually means something
• Hands-on experience working with LLMs in applied contexts
• Comfort with RAG, agentic architectures, and modern LLM tooling
• Ability to evaluate and validate AI system behavior - understanding what the model is doing and why
• Clear written communication

Benefits

• Base salary: $180,000 - $230,000
• Meaningful ownership in a fast-growing healthtech startup
