SEMIFIVE Tech Stack

Custom silicon design partner connecting fabless companies to Samsung foundry

Semiconductor Manufacturing Bundang, Seongnam-si 201–500 employees Privately Held

SEMIFIVE bridges fabless design teams and Samsung's manufacturing capacity, focusing on design-for-testability (DFT) and physical implementation for complex SoCs. The hiring profile—concentrated in senior and lead engineering roles across DFT, timing closure, and verification—reflects a company scaling specialized chip-design expertise rather than broad headcount, while active projects on automation and multi-corner signoff suggest internal tooling maturity to handle the cost and complexity pain points their customers face.
