About the role

Summer internship in engineering at Flint (San Francisco, on-site) focusing on end-to-end product work across the stack, including UI and infrastructure, leveraging LLMs and agent workflows, with a production-quality deliverable and potential full-time offer discussion.

Responsibilities

  • Own a part of the product that's live with customers and stays live after you leave.
  • Work anywhere in the stack, from the UI down to the infrastructure it runs on.
  • Use LLMs and agent workflows as everyday tools. The product is built out of them.
  • Ship to production in your first few weeks, then keep going.
  • At the end of the summer, show the whole company what you built and what it moved.

Qualifications

  • You're in your penultimate or final year of an undergraduate degree in Computer Science, Computer Engineering or Software Engineering.
  • You've built and shipped something we can look at: a repo, a product people use, or a hackathon project we can open and try.
  • You're happy to pick up work anywhere in the stack.
  • When something breaks, you find out why before you change anything.

Benefits

  • A named engineering mentor, plus a weekly one-to-one with your manager that doesn't get cancelled.
  • One project with your name on it and a before-and-after number to show for it.
  • Lunch in the office. The team is small enough that you'll know what everyone is working on.
  • A conversation about a full-time offer before you go back to school, not a form letter in October.
