Job description

Team of ~10, in-person in SF.
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. 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, Scale, and Shepherd (YC W21), and work together in-person out of historic Jackson Square.
The product
Companies have used Flint to hit goals like...
  • Ranking #1 on AI answer engines like ChatGPT, Perplexity and Google AI Overview
  • Lifting ad conversion rates
  • Generating hundreds of thousands of dollars in pipeline revenue

The role
As a Software Engineer at Flint, you'll build the systems behind AI-native websites: agents that design and ship real web experiences, the code-generation and editing infrastructure under them, and the product that ties it together.
It's a broad role by design: we're small, so you'll move across frontend, backend, and the agentic systems depending on where the hard problem is that week.
What you'll own
  • Agentic systems that design and launch web experiences using current-best applied-AI techniques.
  • Flint's core application across frontend, backend, and infrastructure.
  • Evals, observability, and testing for AI systems, the work that makes generated output reliable.
  • Rapid prototyping with users, and turning what you learn into durable features.
  • Architecture calls that stick.
  • Projects end-to-end, from user-tested prototypes to the production systems they become.

We've already tackled problems such as:
  • SOTA applied AI for frontend code generation and design systems
  • Novel UX patterns for AI-first software
  • Distributed multiplayer systems for collaborative editing
  • AST parsing and manipulation for generative code
  • ...and there's much more ahead.

You're a fit if
  • You are a product-first engineer who cares deeply about user experience.
  • You have strong full-stack experience and want to work across the whole stack.
  • You use the latest AI dev tools regularly (Claude Code, Cursor, Copilot, etc.).
  • You take ownership from problem to solution, learning whatever you need along the way.
  • You love building MVPs, testing them with users, and iterating fast.

Bonus
  • You've used website builders (Webflow, Framer) or CMS platforms (Sanity, Contentful, Strapi).
  • You've shipped an LLM feature to real users and dealt with the part where it's non-deterministic and sometimes wrong.
  • You've worked at an early-stage startup or on a small team.

Lunch and a fully stocked snack bar at the office, incl. Cometeer coffee pods
Dog friendly

Our Culture
We are an intensely creative team. After work, we are (avid) readers, photographers, acapella singers, film critics (who don't hold back), bakers, yoga teachers, interior designers, and more.
Catch us in action at our launch party, rock climbing, celebrating birthdays, hosting trivia nights, going for pilates and more.
