About the product
We’re building a platform that makes it easy for non-coders to bring app ideas to life—quickly turning concepts into working products.
The role
We’re looking for a very senior, highly autonomous full-stack engineer—someone who can take an ambiguous problem, turn it into a clear plan, and ship a high-quality solution end-to-end. You’ll work directly with the founders and have significant ownership over product execution and technical direction, touching everything from AI systems and user-facing features to backend infrastructure.
If you’re happiest when you’re building, shipping, and owning outcomes—not waiting for perfect specs—this role will fit.
What you’ll do
Drive features from idea → design → implementation → launch → iteration
Build polished, high-quality user experiences with excellent UX and product craft
Design backend systems/APIs with strong attention to reliability and performance
Make pragmatic architecture decisions and unblock the team with strong technical judgment
Debug hard problems across the stack (performance, edge cases, production issues)
Move fast while maintaining high standards on the things that matter
What we’re looking for (Senior/Staff/Principal traits)
Proven senior-level experience shipping production systems and owning complex projects
Ability to work with minimal oversight and consistently deliver
Strong generalist engineering fundamentals:
System design
Performance and reliability
Low-level problem solving / debugging
True full-stack comfort: frontend + backend (a spike in either is a plus)
Strong product sense: you care about details and believe craft matters
Required tech
React
TypeScript
Node.js
You’ve shipped meaningful features end-to-end in production using this stack
