About Flint

Flint is the first autonomous website platform. We're building a future where sites can observe, reason and act on their own, adapting in real time to the needs and desires of people and AI agents alike. We've raised a $5M seed round led by Accel, alongside Neo and Sheryl Sandberg's fund, to accelerate this vision. Early adopters include Cognition, creator of the first AI software engineer, and Modal, the leading AI compute platform.

Customers 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 hundreds of thousands of dollars in pipeline revenue.

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

As Founding Software Engineer, you'll build the systems that power AI-native websites, shaping the technical architecture and culture of a company defining the next era of the internet.

Role scope

• Build agentic systems that design and launch web experiences, leveraging cutting-edge AI techniques.
• Develop and maintain Flint's core application across frontend, backend, and infrastructure.
• Design systems with robust evals, observability, and testing to push the frontier of AI reliability.
• Prototype rapidly with users and translate learnings into durable features.
• Lead architectural decisions that set Flint's technical direction for years to come.
• Own projects end-to-end: from prototypes that test new ideas with users to production systems that serve as the foundation for our platform.

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 are a product-first engineer who cares deeply about user experience.
• You have strong full-stack engineering experience and are excited to work across the stack.
• You regularly use the latest AI-forward developer tools (Claude Code, Cursor, Copilot, etc).
• You take ownership from problem to solution, learning whatever you need to succeed.
• You love building MVPs, testing them with users, and iterating quickly.

Preferred qualifications

• Have used website builders (e.g. Webflow or Framer) or CMS platforms (Sanity, Contentful, Strapi).
• You have built an AI product before
• Experience working in early-stage startups or small teams

If you're excited about this role, but your past experience doesn't align perfectly with every qualification in this job description – we encourage you to apply anyway!

• Competitive salary + equity package
• 20 PTO days / year
• A really beautiful office in Jackson Square, SF
• 2 rooftops, overlooking iconic views (Transamerica Pyramid, Jackson Square)
• A shower in the office - great for freshening up before/after workouts
• Unconditional invites to SF's best AI startup events
• We explicitly encourage our team to grow and extend their networks.
