Job description

About Yaay

We're building the taste layer for the physical world: the app that knows what you actually love and turns it into places to go.

We're building the taste layer for the physical world: the app that knows what you actually love and turns it into places to go.

Today: See it. Save it. Do it.

• Spot a place on social, save it in one tap, and our AI finds the exact spot, pins it to your map, and helps you plan and book it.

Where we're going

• The app you open to go out in your own city with your friends, that inspires and pushes you into the world, and that truly feels social.

Our product philosophy

• AI is the engine, not the show. We use it heavily, but users don't need to know or care. It's hidden and helpful, never flashy for its own sake.
• We kill choice overload. People are drowning in options. We get them to the right one while feeling confident they're not missing something better.
• Complex inside, dead simple outside. Features can be intricate behind the scenes, but should always feel effortless to use.
• Convention over configuration. The common case is the happy path, with an escape hatch for when you need more control.
• Validate, but trust the vision. We test product decisions with real signals, and we hold our nerve on the long-term direction we believe in.

About The Role

• Take our React Native / Expo app to the next level and own the craft of how it feels in people's hands
• Work closely with the founders and designer in a flat, autonomous team, reporting to Christian (CTO)
• Remote-friendly (within UTC−3 to UTC+5 for 4-5 hour overlap with Denmark), with our home base in the Copenhagen city-center office. If you’re in Denmark we do require you to be in Copenhagen

What You'll Do

• Ship a polished, native-feeling app and sweat the details: animation, haptics, the small touches that make it delightful
• Turn a vague idea or a napkin sketch into a real, shipped feature
• Explore different routes to a feature while keeping focus on getting it into users' hands
• Put yourself in the user's shoes on every decision

What We're Looking For

• Extensive React Native experience and a background building native mobile apps
• A feel for polish: you know where a little animation or haptic makes the difference
• Comfortable working autonomously from loose direction, not a fully scoped spec
• A real passion for travel, and an understanding that everyone travels differently
• Consumer app experience is a big plus, as is Swift/Objective-C or Kotlin/Java (nice to have, not required)

How We Work

• Engineering here is creative work. Our process is exploratory, and finding the best solution is part of building it
• We move from idea to shipped feature without waiting for everything to be fully designed first

Why Yaay

• An early, pivotal seat at an ambitious startup taking on travel and leisure, a space that touches almost everyone
• Real autonomy inside a flat, joyful team
• Room to grow with the company as it scales

A note on fit: We keep a relaxed hierarchy and high expectations at the same time. If you're excited to push hard and help make Yaay a success, you'll fit right in. If you're after a calm nine-to-five, this probably isn't the one.
