Careers at joayo

Build joayo with us.

We are a small, senior team in Seoul making everyday neighborhood life a little better. If you care about real merchants, real customers, and shipping quietly good software — we want to meet you.

How we work

Four things we hold close.

These aren't posters on the wall. They show up in how we review code, price features, and talk to merchants.

  • Stay close to the street

    Everyone — engineers included — spends time with merchants and users. Product decisions stay grounded when the people making them have been behind the counter that morning.

  • Positive, never slick

    We don't do dark patterns. Offers are honest, loyalty is earned, and voice is warm and specific. If it would embarrass your neighbor, it doesn't ship.

  • Small tools, deep craft

    We'd rather ship one feature that works beautifully than five that kind of do. Typography, copy, and edge cases are not details — they are the product.

  • Write things down

    Async by default, thoughtful in writing. Decisions live in shared docs; meetings exist to decide, not to broadcast.

What we offer

Benefits that actually land.

Designed to let you do your best work, rest properly, and stay in your neighborhood.

  • Meaningful equity

    Every full-time hire gets a stake. We explain vesting plainly in the offer letter.

  • Private health coverage

    Top-tier private insurance for you and your family, on top of Korean national health.

  • Learning budget

    ₩1,500,000 per year for books, courses, or conferences you actually want to attend.

  • Home office setup

    Full kit — laptop, external display, chair. Replace anything that slows you down.

  • Flexible hours

    Core collaboration window is short. Work when you think best; protect your evenings.

  • Quarterly offsites

    The whole team meets in person four times a year — usually somewhere the food is good.

Open roles

Join the team.

Don't see an exact fit? We still want to hear from strong people — send a note with what you'd want to work on.

  • Seoul (hybrid)·Consumer

    Product Designer

Inside joayo

A quiet office, loud neighborhoods.

We work from a bright studio in Yeonnam, and from counters, cafés, and markets across the cities where our merchants live.
