Founding Frontend Engineer​/Design Engineer

tl;dr:
Why choose Flint? ⚡
We’re winning quickly.

• We’re backed by Accel, the same partner who led the series A for Scale, Vercel, and Sentry. We launched out of stealth 2 months ago (Tech Crunch), and are already powering pages that generate hundreds of thousands of dollars in pipeline. Also recently featured on CNBC.

• Flint has thousands of companies on our waitlist with more coming inbound every day. The market has spoken. We’re growing our team so we can stop turning away customers.

• We’ve earned the trust of customers like Cognition, Modal, Reducto, and Tandem + more we don’t publicly reference. Our new gong has been put to great use!

Flint is defining the next generation of websites: ones that can constantly build and optimize themselves based on visitor behavior and market changes. Today, we deliver on-brand landing pages on your domain fast, without any rebuilds or engineers. We are backed by Accel, Sheryl Sandberg (former Meta COO)’s venture fund SBVP, and Neo.

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’.” — Tech Crunch

Imagine a world where your website launches new pages, tests creative, and optimizes performance entirely autonomously. Just as autonomous vehicles respond to real-world inputs like road conditions and traffic patterns, Flint-powered websites respond to external signals such as competitive shifts, user behavior, and trending search queries.

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 (YCS
23).

Every single member of the Flint team has been a founding engineer / founder. Early stage best practices are in our team’s DNA. Because of that, our team knows how to catalyze hockey stick growth, but just as critically, how to navigate it sustainably to create $XB valued companies. After all, we’ve done it before.

We are alums of Netflix, Splunk, Scale, Carrot, and Shepherd (YC W21), and work together in-person out of historic Jackson Square.

The first version of Flint's autonomous website platform produces on-brand landing pages from content briefs and prompts in minutes.

It’s also about incorporating taste into the AI to produce beautiful websites for our customer’s users.
