Job Description

The Role

We are looking for a Full Stack Engineer who thrives on building resilient, distributed systems and great user interfaces. In this role, you will be the architect of the services that power our global treasury operations. You will design mission-critical systems that automate the movement of massive volumes of money, ensuring our "plumbing" is invisible, fast, and fail-safe.

What You'll Do

Architect Distributed Systems: Design and maintain scalable microservices (primarily in Java/Spring Boot) capable of handling billions in monthly volume with zero downtime.

Product Design: Propose and build the user interfaces to allow operations work efficiently and safe.

Solve Global Logistics: Develop the logic that handles real-world constraints, such as bank-specific API quirks, holiday schedules, and regional settlement cut-offs.

Data Integrity & Reconciliation: Build and optimize the data infrastructure that ensures every movement of money is accounted for, creating a source of truth for our data-driven decision-making.
