Product designer

Travel is essential, whether it's visiting family, starting a new adventure, or taking a career-defining trip. Yet over 4 billion airline passengers rely on tech that hasn't changed in decades. At Duffel, we're rebuilding the infrastructure underpinning the global travel industry. Backed by top-tier investors (Benchmark, Blossom, Index Ventures and Kima Ventures) and born out of Y Combinator (S18), we're simplifying complex systems to build the future of travel.

• Own end-to-end design for our AI support product, from discovery and flows to prototypes and shipped software, in a product where airline rules, payments and customer expectations all collide.
• Run discovery with customers and the travellers they serve, and turn needs from multiple stakeholders into clear, prioritised requirements.
• Be the voice of design at Duffel: set and uphold the quality bar across craft, accessibility and consistency, and raise it in every review.
• Work shoulder to shoulder with Product Managers and engineers to take designs through to delivery, then learn from real usage and feedback quickly.
• Explain the why behind every design decision, welcome challenge from anyone, and change your mind when the evidence says so.
• Design how AI and people work together: what the AI should do, when it hands over to a human, and how users understand, trust and correct it.
• Bring ideas from other products and industries to Duffel, and share them so the whole team's design thinking improves.
• Designing the experience of an AI support agent that answers travellers and hands over to our travel support team when it should.
• Defining the patterns for AI behaviour: when it acts, asks, escalates or defers, and how users see what it did and why.
• Building tools for the businesses on Duffel to review, correct and trust what the AI does on their behalf.
• Helping other teams with their design needs when they ask, and sometimes when they don't yet know they have one.
• Sharing design progress, rationale and open questions weekly with product, engineering and operations,

• 5+ years designing digital products, with a portfolio that shows you've taken a complex product from problem to shipped outcome and can say what changed because of it.
• Strong craft across interaction, visual and systems design: you ship the states, edge cases and accessibility, not only the happy path.
• Experience working with several stakeholder groups at once, ideally both business customers and end consumers, and a clear method for turning their conflicting needs into decisions.
• Experience designing AI, conversational or support products, and an understanding of what makes them hard: uncertainty, failure states, trust and handover to humans.
• A close working relationship with engineers and PMs, including prototyping in code or with AI tools where it speeds up learning.
• A collaborative mindset with a strong point of view: you push back with evidence, take feedback well and can articulate the why behind any design.
• The confidence to hold a quality bar and speak for design across the company. You influence without authority and you're happy to set the example.

• We believe in true ownership. That’s why every permanent employee gets equity in the business.
• Travel Allowance: We literally pay you to get out of town and explore the world.
• Work From Anywhere: Flexibility is built in. Work remotely, or take advantage of our Sabbatical Policy.
• Electric Car Scheme: Roll up in a brand-new EV with eco-friendly tax savings.
• Work-Life Harmony: Flexible bank holidays, generous family leave, and a dedicated volunteering day.
• Growth Tools: Paid study days to level up your skills, plus a solid pension and cycle-to-work scheme.
• Health & Wellbeing: Private healthcare, eye test cover, and season ticket loans.
• Family Leave (maternity, paternity and adoption)
