Job description

North is a digital product studio from Barcelona. We partner with bold companies to innovate new services and build digital products. Our values are: show your passion, act as an owner and think rigorously, figure it out & hold the line.

As a Conversational AI Designer working with North you will partner with internal and external teams to understand, craft, prototype, measure and improve the best conversational experiences in the world. If you are a truly great collaborator for this role, you will be passionate about LLM-based, non-deterministic conversational experiences, and understand why they matter on a human level, as well as from a business perspective.

What you will do:

• Design conversational experiences (assistants, agents) that are non-deterministic and built on LLMs, rather than scripted flows.
• Identify and analyze use cases, diagramming them clearly for design, engineering and product teams.
• Run and evaluate tests on conversational agents, iterating on the experience based on results.
• Collaborate closely with data teams on prompt design and refinement.
• Define evaluators and quality frameworks to assess and continuously improve conversational performance.
• Ensure a coordinated, coherent experience across conversational design patterns.

You will bring to the table:

• Proven experience as a conversational designer working on non-deterministic experiences (assistants, agents) built on LLMs.
• Solid understanding of how LLMs work and how that shapes conversational design decisions.
• Experience identifying, analyzing and diagramming use cases for conversational products.
• Hands-on experience testing conversational agents and interpreting the results.
• Experience collaborating with data teams on prompt definition and iteration.
• Experience defining evaluators and frameworks to measure conversational quality.

But 'what's in it for me', I hear you ask?

• A hybrid work from home/office system with a flexible time schedule. When you do happen to come to the office, there will always be fresh fruit, coffee and snacks.
• Macbook Pro 13" or similar.
• Your birthday as an extra paid vacation day.
• Legendary social events & parties to let off some steam.

North is proud to be an equal opportunity employer. You're welcome on the team no matter where you're from, who you like, what you look like, or if you prefer Figma over Sketch. We hire based on your qualifications and demonstrated ability to perform job responsibilities. Our designs are for everyone, and so is our workplace.
