Job description

This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

The role

This company helps content creators launch their own branded membership products, providing essential tools for content hosting, payments, growth, and AI features. They are bootstrapped, profitable, and have recently tripled revenue, serving hundreds of thousands of end users.

This is the first engineering hire, working directly with the technical co-founder. You will lead the agentic and AI-powered side of the platform, owning features end-to-end from concept to deployment. This isn't a ticket-taking role; it's about building a creator operating system, shipping daily based on direct user feedback, and seeing your work impact hundreds of thousands of users immediately.

The work

• Design, build, and ship agentic and AI-powered features, taking them from vague briefs to production.
• Engage directly with content creators to understand needs, then rapidly prototype and deploy solutions.
• Own significant product areas end-to-end, from ideation through to deployment and iteration.
• Operate in a high-leverage environment, using modern AI coding tools like Cursor, Claude Code, or Codex daily.
• Contribute across the full stack, ensuring robust and scalable solutions for a platform serving hundreds of thousands of users.

What You Bring

• 3+ years of engineering experience at a product-driven company.
• Proven experience shipping agentic or AI-powered features in production, navigating non-deterministic systems.
• Full-stack fluency: Next.js, Node, Postgres, Stripe, AWS.
• Daily proficiency with AI coding tools (e.g., Cursor, Claude Code, Codex).
• A builder's mindset: you thrive on ambiguity, drive projects to completion, and contribute to product strategy.
