Jobs in San Mateo, CA

About the role

We're looking for exceptional Research Engineers who enjoy turning cutting-edge AI research into production systems used by enterprise customers. This role sits at the intersection of research and engineering - you'll design experiments, invent new approaches, and ship systems that directly impact customer experience.

What you'll bring

• 5+ years of experience in applied machine learning, NLP, large language models, or AI research, with a proven track record of shipping production AI systems.
• Master's degree
• in Computer Science, Machine Learning, Artificial Intelligence, NLP, or a related field required
• Deep experience with modern LLMs and agent architectures.
• Strong software engineering skills with production-quality Python and experience using modern AI frameworks.
• Demonstrated ability to design rigorous evaluation frameworks, benchmark models, and make data-driven decisions balancing quality, latency, cost, and reliability.
• Demonstrated ability to improve model cost/quality through experimentation—including retrieval optimization, fine-tuning, distillation, inference optimization, and agent design.
• Publications at leading AI or NLP conferences (ACL, EMNLP, NeurIPS, ICML, ICLR, NAACL, CVPR) or meaningful contributions to open-source AI projects.
• Experience adapting foundation models and deploying production-scale LLM systems.
• You'll Thrive Here If You...
• Think scientifically and validate ideas through rigorous experimentation.
• Care equally about elegant research and measurable production impact.
