What You'll Do

  • Design, train, and deploy production ML systems that integrate LLM-powered agents with time-series models.
  • Build and scale LLM-powered agents with advanced capabilities, including multi-step reasoning, tool integration, and autonomous workflows.
  • Develop and refine evaluation frameworks for agents, ensuring reliability, safety, and measurable performance.
  • Apply and extend time-series modeling techniques such as forecasting and anomaly detection in real-world customer scenarios.
  • Operate end-to-end: from data ingestion and preprocessing to deployment, monitoring, and continuous improvement.

Requirements

  • Proven industry experience (4-10 years) as an ML Engineer, Research Engineer, or Applied Scientist, with a track record of shipping production ML systems.
  • Hands-on expertise in LLM-powered agents, including multi-step reasoning and autonomous workflows.
  • Deep understanding of agent evaluation techniques, focusing on reliability and safety.
  • Up-to-date with modern agent infrastructure and frameworks (MCP, A2A, etc.).
  • Fluency with ML engineering best practices: reproducibility, monitoring, scaling, and CI/CD.

Nice to Have

  • Experience training custom neural networks beyond pre-trained LLMs, such as transformers for time-series or multimodal data.
  • A background in time-series modeling, including forecasting and anomaly detection.
  • Published research or open-source contributions in ML/AI.

What We Offer

  • Competitive salary range of $140,000 - $180,000 per year.
  • Relocation support to help you settle in the San Francisco Bay Area.
  • Visa sponsorship options available (H1-B, O1).
  • Opportunity to work with a talented team and make a significant impact in the AI field.
  • Flexible working environment with a focus on innovation and collaboration.
