Flint is the first self-improving system for performance marketing. We connect to brands' ad accounts and optimize them through creating pages instantly for each ad group and running a learning loop that continually improves conversions. We just signed a Fortune 10 customer, and within 48 hours their customer acquisition cost decreased by 50%. We're backed by Accel, Sheryl Sandberg (former Meta COO)'s venture fund SBVP, and Neo.
What you'd do
- 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.
- This role is onsite in our San Francisco office, five days a week, for the full 16 weeks: Monday 3 May to Friday 20 August 2027.
- You must already be authorized to work in the United States for the whole term. We don't sponsor visas for internships, and the application asks you to confirm this.
- 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. We weigh this heavily, and we don't ask for your GPA.
- You're happy to pick up work anywhere in the stack.
