The Role

Were looking for a Backend Engineer with deep Node.js and TypeScript experience to architect and scale systems that support a global user base. Youll own the core backend logic, APIs, and integrations that power the platform.

Youll play a key role in shaping a new financial product that blends Web2 reliability with Web3 innovation, bringing stablecoin‑enabled credit cards and intelligent financial tools to a global audience.

Youll work directly with the founder on a small, high‑ownership team that moves fast, cares about craft, and enjoys solving complex problems together.

What You’ll Do

• Design and implement backend systems and APIs using Node.js and TypeScript.
  
• Own architecture, reliability, and performance of backend services.
  
• Work closely with frontend engineers to deliver robust end‑to‑end features.
  
• Optimize systems for scalability, maintainability, and security.
  
• Move fast — ship, iterate, and improve continuously.

What We’re Looking For

• 5–8 years of backend engineering experience.
• Strong expertise in Node.js, TypeScript, and REST API design.
• Deep understanding of databases, caching, and system design.
• High sense of ownership and initiative — you build, test, and deploy confidently.

Nice to Have

• Familiarity with cloud infrastructure (AWS, GCP) and CI/CD pipelines.
• Interest in AI, automation, or scalable data systems.
• Experience in startup or lean engineering environments.

• Frontend: React Native (Expo) app styled with Tailwind CSS and built on the Gluestack UI component library
• Data Layer: TanStack Query for efficient data fetching and client-side state management via REST APIs
• Backend: Serverless Node.js architecture using NestJS for API services and asynchronous job handling on AWS Lambda
• Database: PostgreSQL as the primary relational datastore
• Infrastructure: Fully deployed and managed on AWS with Terraform for infrastructure as code
• Tooling: Modern developer stack including GitHub, Slack, Notion, Linear, and Graphite

Why Join Us

• Work directly with the founder — shape key architecture and engineering decisions.
• No process overhead — just build and ship with speed and quality.
• Join a high‑trust, outcome‑driven engineering culture.
• Fully remote, flexible work built on ownership and autonomy.
