Technical search for semiconductors in Vietnam.

Semiconductors stratify more sharply than most industries, and the layer an employer sits in decides which decisions ever reach the people inside it. A fabless company owns the architecture, the product and the cost of being wrong in silicon. A foundry owns the process. An OSAT owns the package and the test floor as a service. A design service partner owns execution against a specification written by the customer. All four hire engineers with the same titles, and all four are hard to do well. That is why the clearest split is not seniority but whether the work was owned or executed. Two DFT leaders can each have run sixty engineers. One set the test strategy before tape-out, trading silicon area on compression against tester seconds that become cost of goods at volume, and lived with it when the part came back hard to test. The other ran scan insertion and pattern generation against a specification that arrived from elsewhere, on someone else's schedule, and did it well enough to keep winning the next project. Same title, same headcount, same vocabulary.

Vietnam now has engineers across every one of those roles — assembly and test, design services, captive design centres, and a domestic fabless industry just getting off the ground — so a shortlist can look uniform and actually come from four different worlds. Sometimes two centres under the same logo can be two different worlds — one owns the block end to end, the other just carries out decisions made in Santa Clara, Hsinchu or Seoul.
