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. ## About Flint ## Company Overview - **One-liner**: Flint is an AI-powered autonomous web platform that builds, optimizes, and updates marketing pages for growth teams. - **Entity Type**: Private (Seed stage) - **Headquarters**: San Francisco, CA, USA - **Founded**: March 2025 - **Founders**: Michelle Lim (CEO) and Max Levenson (CTO) ## Core Business - **Primary industry**: AI-powered marketing & web infrastructure - **Target customers**: B2B marketing and growth teams at rapidly growing startups and Fortune 500 companies (CMO persona) - **Mission or purpose statement**: To create websites that continuously build and optimize themselves based on visitor behavior and market changes, eliminating the need for engineering involvement in marketing pages. ## Products & Services - **Flint Platform**: An autonomous web platform that scans a company's existing site to capture brand identity and component library, then generates fully coded, on-brand landing pages optimized for conversion and SEO. Features include automated A/B testing, analytics integration, form tracking, ad optimization, and an MCP/API for integration with GTM tools like Claude, Clay, and Relay.app. - **Flint MCP & API**: Enables teams to generate targeted account-based marketing pages directly from their existing workflow tools and CRM. ## Market Standing - **Valuation/Market Cap**: Not publicly available (seed stage) - **Total Funding**: $5 million in seed funding (announced October 2025) - **Lead Investor**: Accel - **Notable Investors/Partners**: Sheryl Sandberg (via Sandberg Bernthal Venture Partners), Neo (existing backer) - **Key Customers**: Cognition (Windsurf), Modal, Graphite - **Growth Signals**: The company emerged from stealth in October 2025 and already has live, public-facing customers. Claims a 3x conversion rate increase and 50% reduction in CAC for customers. ## Competitive Advantages - **Autonomous optimization**: Unlike AI website builders (Lovable, Cursor) aimed at developers, Flint is built specifically for marketing teams to ship pages without any engineering maintenance. - **Brand consistency**: Captures a live site's exact component library rather than using templates — pages are perfectly on-brand and pass brand team review. - **Integration-first**: Works alongside existing CMS tools (Webflow, Framer, Next.js, WordPress, Sanity) and all major analytics/A/B testing tools. - **Founding team pedigree**: Led by Michelle Lim (Engineer #1 + Head of Growth and Product at Warp) and Max Levenson (Engineer #2 at Vooma, former autonomous vehicle engineer at Nuro). Team includes alumni from Netflix, Warp, Nuro, Figma, Scale AI, Reddit, and Meta. ## Strategic Focus - **Near-term**: Automating the full page creation workflow for marketing teams — from brand import to deployment — while customers still provide copy. Content writing functionality is approximately one year away. - **Long-term vision**: Websites that perform their own A/B tests, dynamically learn from visitors and market trends, and generate personalized pages per visitor (like Amazon product recommendations). - **GTM focus**: Selling directly to CMOs and growth teams at high-growth B2B SaaS companies. ## Why Work Here - **Founding team & culture**: A small, high-agency team of former founders and engineers from top-tier companies (Netflix, Warp, Nuro, Figma, Scale AI). The careers page emphasizes "building the future of the internet" with a flat, builder-focused environment. - **Growth trajectory**: Just emerged from stealth with $5M from Accel and Sheryl Sandberg — early-stage, high-impact roles available across engineering, solutions engineering, and design. - **Backed by top operators**: Investors include Sheryl Sandberg (former Meta COO), signaling strong network effects and strategic guidance. - **Open roles**: Currently hiring across Engineering, Solutions Engineering, and Design (per careers page). Roles appear to be in-person or hybrid given the San Francisco HQ. - **Notable perks**: 14-day free trial for customers (not a perk, but reflects product confidence). No information on specific employee perks (e.g., equity, benefits) is publicly available at this stage. ## Sources 1. [flint.com](https://www.flint.com/careers) 2.
