Job Description

The Role

• 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.
• We are currently only considering local candidates as relocation support is not provided. For local candidates we are able to support transfer of visa sponsorship!

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.
