Job description

Caddi is a seed-stage startup reimagining automation for professionals by transforming simple screen recordings into fully automated workflows. We're building the first true AI-powered automation assistant for lawyers, financial advisors, and other knowledge workers who want to eliminate busywork-without changing how they work.
We're a small, fast-moving team based in Seattle, and we're looking for a sharp, curious Software Engineering Intern to help us validate and improve the workflows built by our AI systems. You'll work at the intersection of engineering, AI, and real-world software tooling-helping us scale from semi-automated processes to truly intelligent automation.
What You'll Do
  • Contribute to the development and refinement of our AI-driven automation engine by improving how workflows are interpreted, validated, and executed.
  • Write and debug Python and/or Go code to enhance core backend systems that interact with large language models and automation agents.
  • Build lightweight tools to inspect, simulate, and evaluate AI-generated plans and their interactions with third-party systems.
  • Collaborate closely with founding engineers to expand our AI pipeline's ability to generalize across user environments.
  • Identify edge cases, inconsistencies, and learnings from real data to improve model prompts, heuristics, and product design.

Requirements
  • Currently pursuing or recently completed a degree in Computer Science, Software Engineering, or related field.
  • Comfortable with scripting and light backend development (Python and/or Golang experience preferred).
  • Strong problem-solving and debugging skills-you enjoy figuring out how things work and making them better.
  • Detail-oriented and methodical-you'll be working closely with real user workflows and production-level automation logic.
  • Based in or able to work from our office in Seattle (Belltown). This is an in-person role.

Benefits
  • Work on the frontier of AI and automation in a fast-paced startup environment.
  • Your contributions will directly shape our product, improve our AI system, and drive user impact.
  • Great mentorship opportunity with experienced founders and engineers.
  • Ideal experience for aspiring backend engineers, systems thinkers, or future founders.
  • Compensation: $30-35/hour, depending on experience and time commitment (30-40 hours/week).
