Salary: Competitive base + Equity — top-tier comp at a world-leading AI lab. Location: Seoul (Hybrid). Company Description: One of the world's most important AI labs — European, building open-weight, open-source frontier models that go head-to-head with the best closed labs. They train the models, not wrap them. Teams across France, the US, UK, Germany, and Singapore — now building in Seoul. Low-ego, ship-fast, research-meets-production. What You'll Do: Take frontier models into real enterprise software — you own the integration end to end. Design and ship scalable full-stack apps where the front-end and back-end actually fit together. Build complex customer use cases and get them running in production, not just in a demo. Work shoulder-to-shoulder with researchers, AI engineers, and product engineers — and push their feedback back into the models. Who You Are: 3+ years as a hands-on IC on hard technical problems. Strong in Python and TypeScript. Comfortable across the stack — React / Next.js / Vue on the front, Node.js on the back. You know your fundamentals — design patterns, data structures, algorithms — and when to ignore them. You can explain a gnarly technical tradeoff to an engineer and a CTO in the same meeting. Fluent in English and Korean. Bonus: you've shipped with LLMs/GenAI, contributed to open source, or worked as a Forward Deployed / Sales / Solutions Engineer or Technical PM. Why Join: Build on genuinely open-weight, open-source frontier models — the ones people actually fine-tune and self-host. Bring frontier AI to Korean enterprises from the front line. Work directly with a global team across France, the US, UK, Germany, and Singapore. Low-ego, ship-fast culture. Competitive comp + equity.
