This role focuses on building and deploying production AI capabilities, especially foundation models and large language model systems. You will optimize LLM performance, implement guardrails and evaluation, and help shape the long-term technical vision for foundational AI systems.

  • Partner with cross-functional teams to deliver AI-powered products
  • Design, develop, test, deploy, and support AI software components
  • Leverage AWS Ultraclusters, Huggingface, VectorDBs, Nemo Guardrails, and PyTorch
  • Invent state-of-the-art LLM optimization techniques
  • Contribute to technical vision and long term roadmap

You will design and operate AI software components spanning foundation model training, large language model inference, similarity search, guardrails, model evaluation, experimentation, governance, and observability. The work uses AWS Ultraclusters, Huggingface, VectorDBs, Nemo Guardrails, and PyTorch, with a focus on LLM optimization for scalability, cost, latency, and throughput.

The ideal candidate is a senior AI engineer focused on production large language model systems, including foundation model training and large language model inference. They bring hands-on experience with guardrails, model evaluation, experimentation, governance, and observability, and they are strong in LLM optimization for scalability, cost, latency, and throughput.
