Engineering Intern — Summer 2027

Job description

## **About Flint** 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 will do day to day - 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. ## **Who you work with** You report to and sit with the engineers who own the part of the product you're working on. ## **Location, dates, and work authorization** - 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. ## **What we look for** - 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. - When something breaks, you find out why before you change anything. ## **What you get** - 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. ## **Hiring process** About two hours in total, and we move quickly. - 30 minutes with Max Levenson, our engineering lead, about your background and what you've built. - A 60-minute technical interview. - 30 minutes with Michelle Lim, our CEO and co-founder. - A decision within one week of the final conversation.
