A Backend Software Engineer Intern assists in developing and maintaining the server-side logic, databases, and APIs that power web and mobile applications. They work closely with senior engineers to write efficient code, troubleshoot issues, and ensure smooth data flow between users and servers. Interns may also participate in code reviews, testing, and documentation to support the overall software development process. This role provides hands-on experience with backend frameworks, database management, and industry best practices.

What skills and qualifications are needed to thrive as a backend software engineer intern?

To thrive as a Backend Software Engineer Intern, you typically need a solid understanding of programming languages like Java, Python, or Node.js, along with knowledge of data structures, algorithms, and database fundamentals. Familiarity with version control systems (like Git), RESTful APIs, and cloud platforms such as AWS or Azure is often required. Strong problem-solving skills, attention to detail, and effective communication help interns stand out in team settings. These competencies are crucial for building reliable backend services, collaborating efficiently, and contributing meaningful code in a fast-paced development environment.

Software Engineer Intern

Caddi

Seattle, WA

$30 - $35/hr

Contractor

Re-posted yesterday

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).
