Principal Product Designer

Why this role exists Travel is personal, even when it's for work. Somewhere along the way, it started to feel transactional. Optimized for cost, bound by rules, and when things go wrong, you're on your own. Serko.ai is built to change that. It's an AI travel assistant that remembers how you like to travel, lets you change your mind without penalty, and proactively monitors for disruptions so you can travel with confidence. It's a new type of travel product that accounts for your life, not just your itinerary. We've built the beta. Now we need you to come build the rest with us. Who should apply You've done 0-to-1 before and you want to do it again. You want autonomy and have the ambition to own a major scope end to end, from strategy to execution.

You want the speed of a startup with the stability of an established company behind you. And you measure design by outcomes, not output. What you'll own The traveller experience, end to end.
