Product Engineer

tl;dr: Why choose Flint? ⚡ We're winning quickly: Backed by Accel, by the same partner who led the first round for Scale, Vercel, and Sentry, plus Sheryl Sandberg's fund SBVP and Neo. We launched in February 2026 ( announced here ), and are already powering pages that generate hundreds of thousands of dollars in pipeline + featured on CNBC . ⚡ Recognized names that turn heads: We've earned the trust of customers like Cognition, Glean, Langchain, Tandem, 11x, + more we don't publicly reference. ( Our gong has been put to great use! )   About Flint Flint is the agentic platform that ships pages from your brand and ad campaigns. AI doesn't replace marketers. It removes the work that should never have been theirs: building a one-off landing page for every keyword, every campaign change, every A/B test, then waiting on design and engineering to do it. Today we deliver on-brand pages on your own domain in minutes, with no rebuilds and no engineers. We're backed by Accel, Sheryl Sandberg (former Meta COO)'s venture fund SBVP, and Neo.   The vision Sandberg instantly understood Flint's vision. "I was sharing how it took (me) five teams three months to build one A/B test just to increase conversion by 10% on our Google ad," Lim said. "And then she stopped me, [and] said, 'Michelle, it was 140 people at Meta who had to do this'." — TechCrunch Imagine a website that builds new pages, tests creative, and optimizes performance in response to real-world signals: competitive shifts, user behavior, trending search queries, the way an autonomous vehicle responds to road conditions and traffic. The marketer still owns the work that compounds and the work that requires taste: strategy, audience, creative direction, brand judgment. Flint takes the manual production off their plate so they get those hours back.   The team "One of the most talent-dense AI startups... each member of the early Flint team has a track record, and as a team, they perform like athletes. Amazing to watch." - Dan Levine, Accel Flint is led by co-founders Michelle Lim , Engineer #1 turned Head of Growth and Product at Warp, and Max Levenson , engineering leadership at autonomous vehicle startup Nuro, then Engineer #2 at Vooma (YCS23). Every single member of the Flint team has been a founding engineer / founder. Early stage best practices are in our team's DNA.
