You Have
  • 5+ years of experience in training and deploying ML models, developing ML software, and shipping customer-facing ML products.
  • Deep understanding of modern ML techniques including Large Language Model Agents and the ML lifecycle: from data collection and training to evaluation, prompting, context management, reasoning, safety evaluation and benchmarking, and deploying models into production.
  • A desire to understand our clients' needs in order to design tools and systems that solve our customer's problems. As a platform team, our main customers are internal developers and products.
  • Ability to produce production-quality code and services incorporating testing, evaluation, monitoring as well as the ability to quickly adapt to a new domain, hack MVP's, and iterate to improve product.
