Semiconductor Design Engineer Jobs in Seoul, South Korea
Seoul and the cities around it, Suwon, Hwaseong, and Yongin, form the center of South Korea's chip industry. Semiconductor design engineer jobs in Seoul, South Korea sit mostly at Samsung Semiconductor, across its System LSI and memory divisions, at SK Hynix, at Magnachip, and at a growing set of fabless startups in the Capital Region.
The work splits along a few lines. Exynos SoC design at Samsung covers CPU, GPU, and modem integration. DRAM and NAND circuit engineering runs deep at both Samsung and SK Hynix. Display driver IC and 5G base station silicon add two more sizable tracks. Because design sits so close to manufacturing here, engineers get early access to advanced process nodes.
Samsung is the largest employer by a wide margin, and its Korean operations hire for nearly every design discipline: memory circuit design, Exynos RTL and physical design, modem work, and foundry PDK and library engineering. SK Hynix concentrates on memory. Magnachip and Silicon Works, the display IC arm of LG, round out the mid-size employers, alongside smaller fabless teams.
The talent pipeline runs through Seoul National University, KAIST, and POSTECH, which supply most of the country's chip design graduates. Korean government funding for semiconductor R&D is large and still growing, so new design centers keep opening across the region.
Compensation is competitive by regional standards. New-grad design engineers at Samsung and SK Hynix often start near KRW 55M to KRW 75M a year including bonuses, and senior engineers move well beyond that. Our salary guide shows how pay shifts by employer and level.
One practical note: most Samsung and SK Hynix roles expect Korean, since the internal working language is Korean. Strong international candidates in areas like GaN, SiC, or AI chip design are sometimes hired at senior levels.
