## Job description

## 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'." — TechCrunchImagine 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, AccelFlint is led by co-founders [Michelle Lim](https://www.linkedin.com/in/michlimlim/), Engineer #1 turned Head of Growth and Product at Warp, and [Max Levenson](https://www.linkedin.com/in/max-levenson-a6102199/), 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

Flint runs background agents that make changes to real codebases and serves AI-generated pages at scale. That creates an infra problem most companies don't have: many agents editing code in parallel, and you have to coordinate, merge, and ship their work without it turning into chaos. You'll own the systems that power all of it: cloud architecture, CI/CD, deployments, observability, and security. It's a 0-to-1 role: you'll inherit a scrappy setup and make it production-grade. Recent work in this role: synchronizing and merging the git output of parallel background agents, building observability for agentic workloads, and hardening deployment pipelines.

## What you'll own

- The concurrency and coordination problems of running many background agents in parallel, the core hard problem of this role.
- Cloud infrastructure end-to-end: architecture, provisioning, CI/CD, deployments.
- Cutting latency and cost as we scale, without trading off reliability.
- Observability and incident response, so we know when things break before users do.
- Security across the stack and deployment pipelines.
- Making it easy for product engineers to deploy confidently and debug fast.

You're a fit if

- You've scaled a product through real user growth and know what breaks, and when.
- You're strong with cloud (AWS or GCP), containers (Docker/Kubernetes), and IaC (Terraform or Pulumi).
- You think in systems, performance, reliability, and cost trade-offs come naturally.
- You can drop into infra you didn't build and make it better without a runbook.

Bonus

- You've been through a startup growth phase.
- Security depth: SOC 2, threat modeling, or pen testing.
- You've built self-service tooling that product engineers actually used.

## 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.
