Job Description

The Role

Hiring Team: Treasury Money Movement. The team's mission is to effectively distribute Treasury operational funds across hundreds of bank accounts timely, at minimal cost & at scale

We are looking for a Fullstack 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.

Qualifications

Technical Excellence

• 3+ years of experience with ideally Java or other JVM-based languages, and hands-on experience with the Spring framework.

• 3+ years of experience with React.

• A track record of writing clean, maintainable code and a strong belief in best practices like code reviews, open feedback, and continuous improvement.

• Familiarity with backend development, including databases (SQL/NoSQL), synchronous/asynchronous communication, and distributed systems.

• Experience with web development technologies such as REST APIs, microservices, and CI/CD pipelines.

• The ability to design technical solutions that balance latency, throughput, adaptability and scalability.

• A passion for learning new technologies, tools, and patterns to solve problems effectively.

Product Mindset

• A customer-first approach — you prioritize work that solves real customer pain points and use data to drive decisions.

• The ability to take ownership of problems, propose solutions, and drive projects end-to-end to deliver measurable impact.

• A knack for identifying opportunities to deliver value faster and providing constructive feedback on product and design decisions.

Collaboration

• Strong communication skills — you can break down complex technical concepts for non-technical audiences and collaborate effectively across teams.

• A proactive mindset — you take initiative to improve our codebase, architecture, and processes.

• A passion for knowledge sharing — you enjoy fostering a culture of learning within the team.
