When you enter the expansive SK Hynix campus in Icheon, which is located about 60 kilometers south of Seoul and is surrounded by low mountains and immaculately constructed rooms, you may notice something that would have seemed strange even two years ago. Mid-sentence, engineers are switching between Korean and English. In both scripts, team names appear on office displays. Additionally, some managers use English nicknames during executive meetings. It’s a minor detail, but in an organization with a deeply ingrained, hierarchical internal culture, it indicates a more significant change occurring beneath the surface.
Employees in SK Hynix’s AI infrastructure team were recently informed to start writing emails in both Korean and English. The company described this as a pilot program aimed at teams that interact with customers worldwide the most. The AI infrastructure team is more than just a supporting department; it manages memory products made especially for AI applications and maintains crucial connections with customers such as Nvidia, a California-based chip designer that is currently the most significant client in the global semiconductor industry. This team at SK Hynix is the one that cannot afford a communication breakdown.
Additionally, the company has advised that employees use English nicknames during executive meetings and intends to gradually translate its business systems into English. Obviously, there is a practical logic to this. However, there’s also a subtle cultural shift taking place: the realization that speaking your customer’s language directly fosters a different type of working relationship than sending everything through translation layers.
It’s difficult not to interpret this as a reaction to the direction the AI hardware market is taking. Nvidia is the de facto gatekeeper of the most valuable supply chains in the industry thanks to its hold on AI accelerator chips. The High Bandwidth Memory that goes with those chips is supplied by SK Hynix, which has become more and more integrated into a California-designed, worldwide-sold product ecosystem that moves at a speed that leaves little opportunity for delayed communication. It appears that the language barrier is no longer regarded as a back-office issue.

The fact that SK Hynix isn’t traveling alone is intriguing. Its longtime rival, Samsung Electronics, has already mandated that certain domestic and foreign affiliates, such as Samsung Display and Samsung Biologics, exchange documents in English. In 2023, Lee Jae-yong, the chairman of Samsung, stated that learning a foreign language entails comprehending not only how people speak but also how they think. That framing remained. Additionally, the notion that English proficiency is a competitive issue rather than merely a question of personal skills appears to be gaining significant traction throughout Korea’s semiconductor industry.
Additionally, SK Hynix is growing its training initiatives. Since earlier this month, it has been conducting a worldwide internship recruitment campaign with an emphasis on business and R&D. A pledge to establish a setting where English can be used regularly, not only in formal contexts, was made at an internal event held at the Icheon campus last month. CEO Kwak Noh-jung has also been talking about increasing the company’s operations’ access to external generative AI tools, such as Microsoft 365, CoPilot, and possibly ChatGPT, subject to security assessments. The picture that emerges is of a business attempting to modernize on several fronts at once, including language, culture, and technological infrastructure.
It’s still unclear whether all of this results in more seamless international collaboration or primarily just puts additional strain on workers who already work in one of the world’s most demanding industries. Mandates for corporate language have a mixed record. Some businesses that heavily relied on English-first policies discovered that the cultural cost was greater than anticipated. For others, it actually unlocked something. By beginning with a pilot rather than a general rollout, SK Hynix may be carefully threading that needle. Alternatively, it’s possible that the pilot framing is merely for show and that the expansion to other teams is already inevitable. In any case, the path appears predetermined. English is the language of Silicon Valley. It seems that Seoul is paying attention.
