Senior LLM Engineer

Title: Senior LLM Engineer Contract:12+ Months Location: San Jose, CA (Hybrid)

We are seeking a highly skilled Senior LLM Engineer to design, build, and optimize large language model (LLM) systems from research to production. This role involves developing model architectures, managing distributed training infrastructure, fine-tuning and evaluating model weights, and deploying scalable inference pipelines. The ideal candidate has deep expertise in transformer-based architectures, GPU/TPU optimization, and prompt or instruction tuning. You'll collaborate with cross-functional teams to advance our LLM capabilities, improve efficiency, and deliver high-performance generative AI solutions.

Key Responsibilities:

• Design, train, and fine-tune large language models using PyTorch or JAX.
• Manage distributed training and model optimization across GPTPUs.
• Develop and maintain scalable LLM infrastructure for experimentation and deployment.
• Evaluate model performance and implement techniques for continual learning and alignment.
• Collaborate with ML researchers and product teams to integrate LLMs into real-world applications.

Qualifications:

• 5+ years in ML/AI engineering, with 2+ years focused on large-scale language models.
• Strong understanding of deep learning frameworks (PyTorch, TensorFlow, JAX).
• Experience with model parallelism, quantization, and fine-tuning techniques.
• Familiarity with MLOps tools, vector databases, and cloud infrastructure (AWS, Google Cloud Platform, Azure).
• Background in NLP, transformer architectures, and reinforcement learning from human feedback (RLHF) a plus.
