This is a unique opportunity to drive engineering practices and make a real impact in a rapidly expanding international company.

Technical Stack

Programming Languages: Java 17

Frameworks: Spring Boot, JOOQ

API: RESTful APIs, API design (treated as products, often public in Open Banking)

Event-Driven Architecture: SNS+SQS, Kafka

Collaboration Tools: Close collaboration with Product Owners on user needs, business opportunities, and regulatory requirements

Key Responsibilities

- Event-Driven Microservices: Contribute to the design, development, and maintenance of microservices in an event-driven architecture (200+ services owned by 40+ teams), ensuring global scalability.

- Service Ownership: Own the full lifecycle of services, including design, building, running, and scaling them across the platform.

- API Development: Expose and consume RESTful APIs, with a focus on good API design, treating them as products, especially in the context of Open Banking where many are public-facing.

- Event Processing: Use SNS+SQS and Kafka for event-driven messaging and processing.

- Database Management: Utilize PostgreSQL via Aurora as the primary datastore, integrating seamlessly with AWS infrastructure.

- CI/CD: Deploy services to production multiple times a day using CI/CD pipelines powered by GitHub Actions, ensuring quality with JUnit/Pact testing.
