The job postings went up quietly, but the effect was immediate. ASML, Lam Research, Applied Materials and Tokyo Electron, the four companies that make the machinery used to manufacture advanced semiconductors, are all recruiting in South Korea with unusual intensity, hiring both new graduates and senior engineers as Samsung Electronics and SK hynix pour billions into high-bandwidth memory and advanced DRAM production lines.
The reason is simple: where the fabs go, the toolmakers follow. Samsung and SK hynix, the world’s two largest memory makers, are expanding their HBM capacity at a pace that has no precedent in the industry, and every new line needs lithography systems, etching tools, deposition equipment and the engineers who install, tune and repair them. Equipment companies have opened or expanded offices in Korea, and recruiters said the competition for experienced engineers has become fierce, with signing bonuses and relocation packages that would have been unthinkable a few years ago.
The talent war reflects the changing shape of the semiconductor industry. For years, the equipment makers treated Korea as an important but secondary market, with their biggest operations in Taiwan, Japan and the United States. The memory boom has changed that calculus. Korea is now the center of the world’s HBM production, and the equipment companies need people close to the action, both to serve existing customers and to win the next round of orders. Engineers with experience in memory process technology are the scarcest commodity in the industry, recruiters said.
The hiring is happening on two tracks. New graduates are being courted with training programs and the promise of working on the most advanced equipment in the world, a draw for young engineers who want to work at the frontier of semiconductor technology. Senior engineers are being recruited with direct offers, often from the fabs themselves, a pattern that has created tension between the equipment companies and their customers. Samsung and SK hynix have historically relied on their own in-house expertise, and the poaching of their engineers by tool suppliers is a new development that industry observers said both companies are watching closely.
The scale of investment explains the urgency. Samsung and SK hynix have committed tens of billions of dollars to HBM and advanced DRAM capacity, and their spending has made Korea the fastest-growing market for semiconductor equipment outside Taiwan. The equipment makers, which saw revenue surge during the AI-driven chip boom, are now investing in local presence the way they once invested in Taiwan, building service centers, training facilities and, increasingly, local engineering teams.
For the engineers themselves, the competition is a windfall. Salaries for experienced process engineers in Korea have risen sharply, and the companies are competing on more than pay: career paths, research opportunities and the chance to work with next-generation technology are all on the table. Some engineers have moved between the two memory makers and the equipment suppliers multiple times, a pattern that recruiters said is accelerating as projects multiply.
The broader effect is on the equipment industry’s competitive position. ASML, with its near-monopoly on EUV lithography, has the deepest order book, but Lam and Applied Materials are fighting for share in the etching and deposition steps that HBM production depends on. Tokyo Electron, the Japanese company, has been the quiet player, but its strength in the memory equipment segment makes Korea strategically important. The race to hire reflects a race to win orders, and the companies that staff up fastest in Korea may have an edge when the next wave of fab expansion is planned.
Analysts said the talent flow cuts both ways. The equipment companies gain local expertise, but they also train a workforce that may one day return to the fabs, taking process knowledge with them. For now, though, the flow is one-way. “The equipment makers are where the jobs are,” a semiconductor industry analyst in Seoul said. “The fabs built the boom, and now the toolmakers are hiring the people who built the fabs.”
The hiring spree also carries implications for Korea’s own equipment industry. Domestic suppliers have struggled for years to break into the lithography and etching segments dominated by foreign firms, and the arrival of large foreign engineering teams could either squeeze them further or train the next generation of Korean equipment specialists. Some local companies have responded by raising salaries and accelerating their own hiring, a sign that the competition is beginning to reshape the domestic labor market as well.
The Korean government has watched the trend with approval, seeing it as evidence that the country’s semiconductor ecosystem is deepening. The equipment companies, for their part, are simply following the money. Where the memory expansion goes, the machines go, and where the machines go, the people follow.
