• Technical Excellence: Design and maintain robust APIs and services using the Java and Spring ecosystem (Spring Boot, Hibernate, JPA).
• Distributed Systems: Build and manage event-driven architectures utilizing JMS and cloud-native services.
• Security & Reliability: Implement secure Authentication and Authorization protocols at the service level to ensure data integrity in a high-traffic environment.

Required Qualifications

• Core Expertise: Expert-level proficiency in Java and the Spring ecosystem (Spring Boot, Hibernate, JPA).
• System Design: Extensive professional experience in backend engineering within high-traffic, distributed environments and microservices architecture.
• Cloud & Data: Proven experience implementing cloud services (e.g., Cloud Functions, Dataflow) within GCP or AWS.
• Database & Messaging: Hands-on expertise with relational databases and NoSQL/Caching solutions such as Firestore, Redis, or MemoryStore, alongside experience with JMS and Event-Driven Architecture.
• AI Tooling: Advanced proficiency in using Cursor or similar AI-native IDEs to maximize individual productivity and output quality.
• Security: Depth of experience implementing service-level Authentication and Authorization protocols.

Preferred Skills ( "Good to Have ")

• Fintech Experience: Prior experience with payment processing flows, Loan processing flows, bank connection vendors (like Plaid), or working in a highly regulated financial environment
• DevOps Mindset: Experience with containerization (Docker/Kubernetes) and CI/CD pipelines to support a high-velocity delivery model.
