📋 Description

• Build and maintain features across Auth, Billing, and core Business Logic — the systems every customer and team member touches • Own self-serve improvements that reduce friction for users and reduce load on internal teams • Work on the Admin Panel and internal tooling — interfaces that make the team faster and the product more operable • Collaborate closely with product and design to scope, build, and ship across the full stack • Identify gaps in reliability or user experience and fix them without waiting to be asked

🎯 Requirements

• 4+ years building product across the full stack — you've shipped things that real users use • Strong React and TypeScript on the frontend — you write UI that works well and holds up under real usage • Solid backend experience in Python or Node.js — you're comfortable with APIs, databases, and the logic that sits between them • PostgreSQL or equivalent — you model data thoughtfully and understand the tradeoffs • You've worked on Auth or Billing systems before and understand why they require more care than a typical CRUD feature • You take ownership end-to-end: design decisions, edge cases, production incidents, and everything in between • Fluent English — the broader team is in New York and collaboration is daily.

🏖️ Benefits

• Flexible equipment: Laptop and office setup covered so you can work the way you work best. • Food & transport: Meals and rides home covered on late nights. • $150 USD/month wellness stipend: Spend it on fitness, gear, or whatever keeps you at your best. • Flexible PTO: Vacation within normal ranges, taken when it makes sense for you and the team. • Occasional travel: Some trips are part of the role — fully covered when they come up. • Relocation support: Full relocation package available, including for candidates moving from other states.
