[Hiring] AI Engineer @Refine.ink

Role Description

We build AI systems that beat frontier models at specific tasks. Refine 5 is one of them. You'll help us design and improve these systems. The job is getting as much as possible out of today's frontier models.

Qualifications

• A very good mental model of what frontier models can and can't do.
• Excellent intuition for using LLMs, above all inside a system.
• Basic knowledge of MCP, APIs, and tool use.

Requirements

• Not necessarily a conventional ML engineer; credentials don't matter much.
• Experience experimenting with LLMs and achieving unusually good results.
• Ability to code well enough to prototype and test your own ideas.
• Experimental and inventive mindset; talent and output are prioritized over a conventional background.

Benefits

• Opportunity to work with cutting-edge AI technology.
• Collaborate with a small, dynamic team.
• Impactful work that addresses real-world issues.

Refine exists to catch errors in high-stakes work before anyone acts on them. We're building the infrastructure that verifies this work, akin to CI/CD for everything beyond code.
