Founding Product Engineer

We're looking for someone who enjoys finding problems, talking to customers, building solutions quickly, and improving them through rapid iteration. You'll work directly with the founders, product, and design to shape what gets builtnot just how it's implemented. Some weeks you'll build APIs. Other weeks you'll improve onboarding, prototype an AI workflow, optimize infrastructure, or redesign an internal developer tool. Your title doesn't define your scope. The product does.

Responsibilities:

• Build customer-facing product experiences from idea to production.
• Prototype quickly, validate with users, and iterate based on feedback.
• Work across backend, frontend, AI, infrastructure, and developer tooling whenever the product requires it.
• Design systems that are simple, reliable, and easy to evolve.
• Partner directly with founders on product direction and technical decisions.
• Use AI throughout your engineering workflow to dramatically increase speed and quality.
• Continuously improve our engineering practices, tooling, and deployment processes.
• Help establish the engineering culture as we scale.
• Building AI-powered product experiences.
• Using coding agents and AI-assisted development daily.
• Knowing where LLMs work well and where deterministic systems are the better choice.
• Rapidly prototyping with modern AI tooling.
• Thinking critically about evaluation, reliability, guardrails, and user experience.

Requirements:

• We're intentionally not optimizing for years of experience or specific programming languages.
• Instead, we're looking for engineers who have demonstrated the ability to build and ship.
• Built products from 01 or helped scale them significantly.
• Shipped production software that real customers depend on.
• Worked in high-ownership startup environments.
• Built across multiple parts of the stack instead of specializing in one narrow area.
• Made product decisions, not just technical ones.
• Worked closely with customers or internal users.
• Developed a reputation for getting things done.

You'll Probably Enjoy This Role If:

• You have side projects you're genuinely proud of.
• You enjoy shipping more than debating architecture.
• You like talking to users to understand why something should exist before building it.
• You naturally reach for AI tools to increase your throughput.
• You enjoy wearing different hats depending on what the company needs.
• You care about product quality as much as code quality.
• You prefer ownership over hierarchy.
