About the role

SynchrotronAI® builds governed AI agents that do real work: Tariff Agent, Capital Agent, ScamFreeLife, and AI Off Now™.

You will work with our Head of Research on the agents behind these products: how they reason over documents, use tools, stay within governed boundaries, and get measurably better with every release.

What you will do

  • Design and build AI agents that read documents, use tools, and complete multi-step work.
  • Build evaluation suites that measure accuracy, safety, and cost, and use them to guide every change.
  • Test new models as they are released, learn their strengths and limits, and decide where they fit.
  • Work across model providers and techniques: prompting, retrieval, structured outputs, and model customization.
  • Make agents fast, reliable, and affordable in production.
  • Build the guardrails and human-review steps that keep AI under human control.
  • Turn research ideas into product features with the founders.

What you bring

  • A degree in computer science or a closely related field.
  • Three or more years of software engineering experience.
  • Strong Python and TypeScript, and working knowledge of Rust.
  • Hands-on experience building production applications with large language models.
  • Experience designing evaluations and measuring model quality.
  • Sound engineering judgment about reliability, cost, and security.

Nice to have

  • Research experience in machine learning, natural language processing, or AI safety.
  • Experience with agent frameworks, tool use, retrieval systems, and the Model Context Protocol (MCP).
  • Experience with model inference, serving, or GPU workloads.
  • Experience with C++, for example in model inference or other performance-critical code.
  • Publications, open-source work, or competition results.
  • Experience with document-heavy domains such as trade, lending, or government.
