About the Role

We’re looking for a Software Development Engineer III (SDE III) with strong backend expertise and enough full-stack capability to own features end-to-end.

Must-have skills:

Deep expertise in Node.js , MongoDB , Vue.js , and distributed systemsProven track record in building highly stable, scalable backend platformsComfortable contributing to the frontend when needed (this is not a UI-heavy role)

What the role is really about (backend-heavy): You’ll join our Wallet team that powers Wallet, Billing, Taxes, and related services. Your focus will be on foundational, platform-level work:Ensuring rock-solid system stability and performance under growing loadDriving scalability, tech debt reduction, security hardening, and cost optimization Solving complex distributed systems challenges that keep the entire Wallet ecosystem reliable and efficient.

This is a backend-first, full-stack role — you’ll spend most of your time on architecture, performance, and infrastructure while still being able to ship complete features when required. If you love deep backend problems and want to own the stability and scalability of a mission-critical product, this is for you.
