How pay is distributed

Most employers in this selection do not publish a figure, so the range below is Alion's own estimate, derived from 95 comparable listings priced by role, level and country. Across them the middle half of the market sits between $100K and $113K a year, with a median of $103K. By level, the median runs senior at $107K and staff at $132K. The step from senior to staff is worth about 1.2x on median pay. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable.

The market right now

Alion currently lists 95 open Cybersecurity Engineer Salary in Seoul from 28 companies. 41 of them were posted or refreshed in the last seven days. 26 of the employers have posted something in the last three months, which is the pool worth watching if you are starting a search now. 26 of the 95 carry the marks of a stale or abandoned posting - open far beyond the usual time to fill, reposted, or on a board that mostly never closes a role - and are marked as likely inactive; the list can hide them. Every listing links straight to the employer, so you apply on their own board rather than through an intermediary.

Where the work is

The largest concentrations of these roles are South Korea (95) and Hong Kong (1). Most of these positions are on-site roles tied to a specific office.

Who is hiring

The employers with the most open Cybersecurity Engineer Salary in Seoul right now are Coupang (26), Toss (24), 2025. ENKI WhiteHat Co., Ltd. (8), Kurly (4), Gangnamunni (3), and MUSINSA (3).
