Backend Senior On-site 5yr+ Seoul (Gangnam)
Senior Server Developer (Product)
토스 (비바리퍼블리카)
In silos of 6 to 8 people, you'll form a single team with PMs, designers, and data analysts to design backends that withstand massive financial traffic. Beyond just implementing features, the culture is autonomous: you help decide system architecture and product direction starting from the planning stage.
Why this role fits
If you're a senior who has built multiple web services end to end, you can bring that same product ownership straight into a silo. This role fits a service builder who wants to make the design calls in a high-traffic payments domain firsthand.
