Full-time
Benbase is on a mission to scale the trusted benefits advisor.
As a Founding Engineer, you’ll architect and build our AI agent platform. You’ll work across the stack—from thinking how our agents interact human-in-loop to optimizing back-end infrastructure and model accuracy—ensuring speed, scalability, and impact.


We are seeking builders who thrive on speed, iteration, and impact.


What You’ll Do

  • Build and ship our AI agents platform to help automate our brokerage's core internal workflows
  • Develop and refine agentic middleware including prompt engineering and tool calls using Ruby and Python
  • Design and optimize agentic automations for performance, security, and reliability
  • Work closely with our brokerage team to translate ideas from prototypes to production-ready automations
  • Own key technical decisions, ensuring maintainability and long-term impact

Who You Are

  • You love to code
  • Have a strong portfolio or GitHub showcasing full-stack development expertise
  • Proficient in at least two major languages (Ruby/Python/Typescript) and modern front-end/back-end frameworks
  • Experience designing and working with Large Language Models, Embeddings and Prompt Engineering
  • Deep understanding of debugging, performance optimization, multi-stage deployment, and best practices
  • Comfortable in a fast-moving, high-performance startup environment
The ideal candidate is based in San Francisco or New York and can be hybrid a few days a week, but we are open to a fully remote hire.
