Design reliable infrastructure for model deployment, versioning, reproducibility, and orchestration across cloud and on-prem GPU clusters.
Optimize compute usage across distributed systems (Kubernetes, autoscaling, caching, GPU allocation, checkpointing workflows).
Lead the implementation of observability for ML systems (monitor drift, performance, throughput, reliability, cost).
Build automated workflows for dataset curation, labeling, feature pipelines, evaluation, and CI/CD for ML models.
Collaborate with researchers to productionize models and accelerate training/inference pipelines.
Establish ML Ops best practices, internal standards, and cross-team tooling.
Mentor engineers and influence architectural direction across the entire AI platform.

Expertise in ML frameworks: PyTorch, Transformers, vLLM, Llama-factory, Megatron-LM, CUDA / GPU acceleration (practical understanding)
Strong experience with containerization and orchestration (Docker, Kubernetes, Helm, autoscaling).
Deep understanding of ML lifecycle workflows: training, fine-tuning, evaluation, inference, model registries.
Ability to lead technical strategy, collaborate cross-functionally, and operate in fast-paced environments
Bonus Points
Experience deploying and operating LLMs and generative models in production at enterprise scale.
Familiarity with DevOps, CI/CD, automated deployment pipelines, and infrastructure-as-code.
