We’re Making Travel Effortless. Join Us.
Travel is essential, whether it’s visiting family, starting a new adventure, or taking a career defining trip. Yet today, 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.
Product at Duffel Flights is the heart of Duffel's flagship product. Through a single, beautifully designed API, our customers search across hundreds of airlines (NDC, GDS, and LCC), book and generate commission, sell ancillaries like bags and seats, and manage changes and cancellations — all backed by our own agency infrastructure, IATA/ARC accreditation, and ticketing authority.
As Product Manager for Flights, you'll tackle a deceptively hard challenge: take a fragmented, decades-old industry with hundreds of airlines and turn it into one clean, reliable, developer-friendly product. Working at the intersection of engineering, design, commercial, and airline partnerships, you will contribute to the roadmap for a core area of our surface and own how it gets built and delivered.
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.
Location: Shoreditch, London (Hybrid: In-office Tuesdays & Thursdays).
Interview Process: Simple & transparent:

We are an equal opportunities employer. We believe that the key to our success is employing a diverse team, that's why recruitment decisions are only based on your experience and skills. We value your ability to problem solve and build amazing things so we welcome applications for everyone - regardless of age, sex, disability, sexual orientation, race, religion or belief.
