About the role
Senior Software Engineer — Cortex Training at Snowflake. Join the ML Platform team to scale and operate Cortex Training, the LLM post-training platform, handling distributed systems, GPU data plane, and reliability for enterprise-scale ML workloads.
Responsibilities
- Design and build across the full stack — from the public training APIs and SDK through the control plane to the GPU data plane.
- Scale the distributed systems that make GPU compute serverless — multi-tenant scheduling, placement, and capacity-aware routing across regional GPU pools, with fault tolerance built in.
- Drive end-to-end performance at scale — keep the training, inference, and RL loops fast and the data plane responsive under heavy concurrent load, with GPUs kept saturated.
- Productionize research building blocks — partner with Snowflake Research to turn state-of-the-art training and inference techniques into reliable, composable components customers can run at enterprise scale.
Qualifications
- 3+ years (Intermediate) | 6+ years (Senior) building and shipping production ML systems
- Strong distributed systems and infrastructure foundation — designing scalable, fault-tolerant services and operating them on Kubernetes in production.
- Familiarity with GPU and LLM infrastructure — e.g., PyTorch, DeepSpeed/FSDP, Ray, CUDA/NCCL, vLLM; able to debug across the data, infrastructure, and GPU layers.
- Demonstrated ability to harden complex systems for reliability, throughput, and cost efficiency.
- BS in Computer Science or a related field (MS/PhD a plus).
- (Bonus) Hands-on LLM post-training / modeling experience — the strongest candidates pair deep infra skills with real post-training intuition.
