• Own features end-to-end from product discussion and design to implementation and launch
• Build greenfield products for issuers and distribution partners. This is 90%+ of your focus
• Ship fast and iterate. Test ideas quickly, get them in front of users, and learn from the feedback
• Leverage AI. Use AI tools to accelerate your development workflow. Stay critical
• Work across the stack — backend (Elixir/Phoenix + REST APIs) and frontend (TypeScript/Next.js). AWS infrastructure

• Frontend: TypeScript + modern frameworks (Next.js preferred)

• You're AI-fluent. You integrate AI tools into your daily workflow naturally (not for token-burning, just for moving faster)
• You're product-minded. You care about what you're building and why, not just how
• You're independent but collaborative. You can move fast on your own and know when to loop others in
• You're comfortable with ambiguity. You don't need perfect requirements to start building
• You have strong written communication, which is especially important in a distributed, remote-first team
• Prior experience in fintech or crypto
• Production experience with Elixir/Phoenix or Next.js
• Experience building for issuers, distribution platforms, or marketplace-style products
