• Collaborate with development teams to integrate efficient and scalable data access layers into Java / Spring Boot services.

• Modernize legacy database interactions, ensuring high performance, security, and maintainability.

• Lead and mentor teams in writing clean, effective SQL.
• Troubleshoot complex data-related issues, from schema design to query tuning.

• Depending on your knowhow in Java backend technologies and frameworks, you also participate in code reviews, especially on data-heavy components, and provide guidance on best practices for working with relational databases.

Our Tech Stack Includes

• PostgreSQL (core focus), Oracle, MongoDB, Redis

• Java, Spring Boot, Hibernate
• RabbitMQ, Azure Service Bus

• A sound understanding of the opportunities and risks of using the Hibernate ORM framework.

• Experience with API design (REST, SOAP, RPC).

• Familiarity with event-driven architecture and message brokers (RabbitMQ, Kafka, etc.).

• Exposure to cloud-based database deployments.

• Understanding of the insurance or reinsurance domain.

About You

• You’re data-driven and detail-oriented, with a passion for solving complex database and backend challenges.

• You enjoy collaborating across teams, sharing knowledge, and promoting clean, sustainable code and data practices.
