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.
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.
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.
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.
- ApplySeoul (hybrid)·Platform
Senior Backend Engineer
Own the offer and claim pipeline end-to-end. TypeScript, Postgres, and a clean read path that needs to stay under 80ms at p95.
- ApplySeoul (on-site)·Merchant
Head of Merchant Success
Build the team that keeps 10,000+ merchants thriving — onboarding, education, and the voice of the shopkeeper inside the company.
- ApplySeoul·Consumer
Mobile Engineer (iOS & Android)
Shape the consumer app people open every lunchtime. React Native with a native layer where it matters, and a high bar for interaction quality.
- ApplySeoul (hybrid)·Consumer
Product Designer
Design surfaces that feel calm on a busy sidewalk. You care about type, motion, and the difference between 8pt and 9pt in a claim receipt.
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.
