[Hiring] Product Engineer @Refine.ink

Role Description

You'll build Refine with a swarm of AI agents: they write most of the code, and you do the thinking. You own work end to end, from the customer who asked for it, to the code running in production, to the numbers that say whether it worked.

• The work covers the whole product:
• The core AI pipeline.
• The review engine itself: new checks, how frontier models are combined, and what happens when one of them fails.
• Organizations and B2B: self-serve organizations, team and department plans, institutional checkout, and what large clients need next, such as single sign-on.
• Pricing: new plans, packs, discounts and trials, end to end through payments.
• Integrations: Refine already runs inside ChatGPT, Claude and Codex, and there's more to connect.

You'll make the everyday technical calls yourself, so the founders can spend their time on customers and growth. You'll work with Nacho García, who leads engineering, and with the founders, Yann Calvo Lopez (CEO) and Ben Golub (Chief Scientist, formerly a tenured economics professor at Harvard). Our advisors include OpenAI co-founder John Schulman.

Qualifications

• AI-native, for real.
• Strong on architecture and design patterns.
• An engineer with judgement.
• Product-minded.
• An owner.
• Low ego, clear writer.

Requirements

• From idea to production to measured result, without waiting to be told.
• Fluent in English.
• Our stack today is Python and TypeScript on Azure, with Pulumi for the infrastructure.

Benefits

• Competitive compensation.

How we work

• AI-native throughout.
• Small team, strong engineering.
• Autonomy: You choose what to work on, by impact.
• Speed: We build at the speed of AI.
• Remote-first: We're spread across Europe and the US.
• Respect for users: They're sceptical experts; we win them with substance, not hype.
• Meritocracy: Talent, hard work and results are rewarded.

How to apply

Look around refine.ink , then send your CV, LinkedIn or GitHub with short answers to:

• Show us something you built mostly with AI agents. What did you decide, and what did the agents do?
• How do you make sure code written by an agent is correct and well designed?
• What's one thing you'd change about Refine? Why, and how would you know it worked?

How you think matters more than polish.
