Role overview

Machine Learning Engineer - Agentic Systems

Location: Hybrid, San Francisco

Salary: Up to $250,000 + Equity

What you'll work on

  • Design and build the core agentic platform that powers autonomous marketing agents end-to-end.
  • Architect the foundational data and signal layer using a modern lakehouse approach, including robust pipelines and ML serving systems.
  • Build reliable, safe “tool machines” that let agents interact with external systems and the real world.
  • Develop customer-facing applications, such as a seamless chat UI where users collaborate with their AI partners.
  • Collaborate with data scientists to build MLOps infrastructure for training, fine-tuning, and deploying state-of-the-art reasoning models.

What we're looking for

  • 4+ years of experience in machine learning engineering, able to write production-grade code.
  • Experience in either ML platform work (data, infra, serving, MLOps) or ML modelling (training, fine-tuning, evaluation) and ideally both.
  • Product-minded engineer and systems-level thinker who can navigate ambiguity and design for scale, reliability, and extensibility.
  • Comfortable working in an early-stage environment with high ownership, fast iteration, and 4-6 week R&D sprints.
  • Excited about AI agents, performance marketing, and building systems that directly move measurable business metrics.
