Requirements

• Public API Experience: Proven track record of designing, building, and maintaining production-grade public APIs (RESTful APIs, OpenAPI/Swagger, OAuth2).
• Core Backend Stack: Extensive experience with Java and Spring Boot for building resilient backend microservices.
• Distributed Systems & Data: Hands-on experience with event-driven architecture (Kafka or similar messaging systems) and relational database design/optimization (PostgreSQL, MySQL).
• Architectural Knowledge: Proficiency in domain-driven design (DDD), microservices patterns, and building for high availability and low latency.
• Product Mindset: A customer-centric approach to engineering—balancing technical excellence with business context, user experience, and cost efficiency.
• Communication & Collaboration: Ability to convey complex technical concepts to non-technical stakeholders, collaborate across business units, and adapt to feedback.

Nice to Have

• Experience with financial-grade security standards, compliance requirements, or international payment systems (FX, funding, settlement, interbank networks).
• Familiarity with frontend frameworks or infrastructure/gateway tooling.
• Experience maintaining open-source developer libraries, SDKs, or developer portals.

What You Will Be Doing

• Design & Architecture: Architect, build, and maintain highly scalable backend services using Java, Spring Boot, Kafka, and PostgreSQL within an event-driven, microservices architecture.
• API Product Ownership: Set API standards (RESTful, OpenAPI/Swagger, OAuth2) and build developer-friendly tools, SDKs, and reference implementations to reduce integration complexity for major partners.
• Technical Leadership & Mentorship: Champion engineering best practices, conduct code reviews, participate in domain modeling (DDD), and mentor junior engineers across the team.
• Cross-Functional Collaboration: Partner closely with Product Managers, Implementation Managers, Solutions Engineers, and partner development teams to define features, shape technical solutions, and influence product strategy.
• Cross-Organizational Impact: Work across frontend and infrastructure stacks, helping decentralized engineering teams across Wise align with API standards and architecture patterns.
• Global Travel: Collaborate directly with engineering hubs across the globe, including travel to our Tallinn office.
