Job Description

About Flint: Autonomous websites

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.

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'." — TechCrunchImagine 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.

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). Our founding designer Leona Hudelson was previously head of Growth Design at Netflix in charge of optimizing 1B+ visits to netflix.com.

The product

Companies have used Flint to hit goals like…

• Ranking #1 on AI answer engines like ChatGPT, Perplexity and Google AI Overview

• Driving 50% higher ad conversion rates on Google Ads months ahead of schedule

• Generating 7 figures of ARR

The first version of Flint's autonomous website platform produces on-brand landing pages from content briefs and prompts in minutes. Flint ingests a company's existing design system (components, brand guidelines, and visual tokens), then generates fully-coded landing pages that live on the customer's top-level domain, on a subfolder at URLs like companysite.com/campaign-name

The Role

We're looking for a founding product manager who can be the connective tissue between our customers and our engineering team, ensuring we're always building the right thing.

This is an early-stage PM role, which means you'll be wearing many hats. Perfect for someone who's aspiring to found something one day, or grow into a senior product or business operations leader.

Role scope

• Run Tight Feedback Loops into Product & Engineering: Run product discovery and feedback calls to synthesize what customers and prospects actually need. These calls will be done both pre-sales and post-sales. Bring insights back to engineering so we're always building with conviction.

• Embed with Customers: Work closely with enterprise and high-touch mid-market customers during onboarding and adoption. You will experience the friction of enterprise adoption firsthand and bring that context back to the team.

• Prototype and Sales Demos: Build prototypes and demos on Flint to show customers what's possible. Jump into pre-sales calls as the technical voice, acting as sales engineer when needed. Create compelling live demos that get prospects excited about what we're building

• Build the Insights Infrastructure: Help stand up our analytics stack and customer feedback systems. Make sure the whole team always knows where users get stuck, who needs help, and what the funnel looks like.

• Support Product-Led Growth: Design systems that power PLG at Flint, e.g. syncing product usage signals into our CRM so the team knows which customers to prioritize enabling. Build triage systems for customer feature requests so nothing falls through the cracks

• Help Scale the Company: We're a small team in hyperscale mode, so everyone is expected to stretch into many functions. Some weeks you'll be deep in customer discovery; other weeks you'll be sourcing candidates or running a booth for marketing. Nothing is beneath you. That's the feature of early-stage work that makes you dangerously well-rounded

You Might Be a Fit If You...

• A Computer Science, Engineering, or Math degree.

• Have 3+ years in a fast-paced environment where you've touched product, growth, and customer-facing work

• You're familiar with data warehouses, SQL, and product analytics platforms

• Comfort working in fast-moving, ambiguous environments where you shape solutions as much as you implement them.

• Bring a founder's mindset: proactive, resourceful, high-ownership

• See ambiguity as opportunity. You're comfortable operating without a playbook, then writing the playbook as you go
