About the role
- Run pre-training, post-training and deploy state of the art models on clusters with thousands of GPUs. You don’t panic when you see OOM errors or when NCCL feels like not wanting to talk.
- Develop and pre-/post-train domain-specialized foundation models for observability, security, site reliability engineering, and code repair
- Run large‑scale experiments to balance accuracy, latency, throughput, and power under tight memory constraints; profile and fix bandwidth/compute bottlenecks.
- Manage research projects and communications with client research teams.
Requirements
- You are fluent in English, and have excellent communication skills. You are at ease explaining complex technical concepts to both technical and non-technical audiences.
- You have background in adversarial ML, agent/prompt security, watermarking/detectors, differential privacy, or trusted execution (TEE).
- You’re not afraid of contributing to a big codebase and can find yourself around independently with little guidance.
- You’re expert with PyTorch or JAX; strong C++/CUDA or low‑level performance skills a plus; production‑grade Python.
- You don’t need roadmaps: you just do. You don’t need a manager: you just ship.
- Low-ego, collaborative and eager to learn.
- You have a track record of success through personal projects, professional projects or in academia.
- It would be great if you
- Hold a PhD / master in a relevant field (e.g., Mathematics, Physics, Machine Learning), but if you’re an exceptional candidate from a different background, you should apply.
- Have contributed to a large codebase used by many (open source or in the industry).
- Have a track record of publications in top academic journals or conferences.
- Have publications in top ML/security venues and/or contributions to open-source security or observability tools.
- Love improving existing code by fixing typing issues, adding tests and improving CI pipelines.
