Salary

Competitive base + Equity: top-tier comp at a world-leading AI lab

Location

Seoul (Hybrid)

Company Description

A European AI lab building open-weight, open-source frontier models that go head-to-head with the best closed labs. In September 2026 it raised a €3B Series D led by Samsung, with Nvidia participating, at a €21B (about $24B) valuation. 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

  • Run pre-training, post-training, and deployment of SOTA models on clusters with thousands of GPUs. You don't panic at OOM errors or when NCCL refuses to talk.
  • Build SOTA models across modalities (text, image, speech) and invent the methods to push them further.
  • Generate and curate data for pre- and post-training, own the evals, and make the model beat expectations.
  • Build the tooling and frameworks for data generation, training, evaluation, and deployment.
  • Tackle complex use cases with agents and RAG pipelines, and run research projects directly with client research teams.

Required Qualifications

  • Expert with PyTorch or JAX. You write clean, high-performance, fault-tolerant Python.
  • You dive into a huge codebase and find your way with little guidance.
  • You don't need a roadmap to start, and you don't need a manager to ship.
  • Low-ego, collaborative, and always learning.
  • A track record of success in personal projects, industry, or academia.
  • Fluent in English and Korean.

Nice to Have

  • A PhD or Master's in a relevant field (Math, Physics, ML), or an exceptional record from another background.
  • Research range across agents, multimodality, robotics, diffusion, or time-series.
  • Contributions to a large, widely used codebase.
  • Top-venue publications.

Why Join

  • Train frontier, open-weight models on serious compute: thousands of GPUs and real research freedom.
  • Publish, open-source, and ship. Research that actually reaches production.
  • Work with a world-class global research org, from Seoul.
  • Low-ego, ship-fast culture. Competitive comp + equity.
