Full-time; In-person in San Francisco

We’re building the foundation for web presence in the age of AI

Flint is building the first AI marketing engineer to help companies generate, optimize, and grow their brand for human and AI website visitors. We are backed by Accel, Neo, and Sheryl Sandberg.

We’re evolving in two acts. First, we enable companies to generate brand-consistent pages without designers or developers. Second, we become the interface for consumers and their AI agents to navigate the web. Already in the first act, Flint has enabled companies like Graphite.dev to launch landing pages 20x faster with 50% higher conversion.

About the Founders

Michelle Lim was first engineer at Warp, a Sequoia-backed company building the AI terminal for developers. Later, she led Product and Growth. She built Warp's data and growth infrastructure, growing users to hundreds of thousands while helping the company advance from seed to Series B.

Max Levenson was second software engineer at Vooma, the AI agent for logistics. There, he pioneered most of the applied AI stack. At Nuro, he was an early employee (#80) and rose to Staff Tech Lead Manager. During his tenure, he started 5 engineering teams across simulation and infrastructure.

We are a design-forward company—our success depends on excellence in design and brand. Not only will you help build our brand, you'll help elevate the face of the internet itself. You'll be designing the system that could create tomorrow's most iconic brands, turning the static underbelly of the internet into beautiful living creatures.

This is a role for the consummate creative technologist who not only designs, but also codes. You will get to implement product flows you design. You will use the cutting edge web technologies to push the limits of brand design on websites.

Unlike most founding technical roles, this is a unique chance to work with founders who have been in your shoes - our founders were first/second engineers at startups. They understand what it takes to build a successful career as a first engineer, whether you want to develop your IC abilities or gain experience to become a founder.

The Opportunity

Managing web presence poses major challenges for founders and CMOs. Traditional low-code platforms like Webflow haven't solved the problem—companies still need to hire external Webflow agencies, which slows down growth initiatives. Marketing teams also struggle with fragmented operations across various tools. Additionally, the web as we know it is changing: websites are built by AI, websites are now serving AI (agents), and websites are becoming AI. Flint is helping brands and companies build for the age of AI.

As a design engineer, you will be essential to the 0-to-1 phase of a startup. You will…

• Brand design: Design and extend our brand identity and website and creative assets such as our launch video and social media preview
• Product design: Design the Flint product and its core workflows
• Product vision: Work closely with the CEO to develop product vision
  • Transform low-fidelity concepts into high-fidelity designs while participating in creative brainstorming
  • Explore innovative questions like "What if a website builder could hear and see?" and "How might an AI website builder work without a chat interface?"—then turn these ideas into high-fidelity concepts
• Build and maintain the core frontend application using Next.js and Tailwind CSS
• Contribute to discussions on implementing design systems and component libraries in Flint website templates.
• Contribute to various business functions and help drive our company's growth to the next level

You may be a good fit if...

• You have built a brand identity before
• You have brand design and product design experience
• You have frontend engineering experience
• You are passionate about helping companies make beautiful and performant web presences
• You are interested in AI and are curious to learn more about its capabilities
• Bonus:
  • You have a lived understanding of using a website builder (e.g. Webflow or Framer) and/or CMS (e.g. Sanity, Contentful, Strapi)
