Design, develop, test, and maintain backend services and APIs using Java
Write clean, maintainable, and well documented code following best practices and coding standards
Own high-level and low-level design (HLD/LLD) for assigned modules/services;
Design and build event-driven services and integrations (e.g., Kafka), including idempotency, message ordering, and resilient handling of unreliable upstream and downstream systems
Design and build clean API and error contracts that decouple consumers from the systems behind them
Coach & Support Junior Engineers while fostering high code quality & engineering excellence
Collaborate closely with product managers, QA engineers, and other developers to deliver features on time




Implement unit, integration, and (where relevant) performance tests to ensure software quality
Troubleshoot and debug production issues, performing root cause analysis and implementing long-term fixes

Ensuring security, scalability, and reliability are considered throughout the development lifecycle
Stay current with Java and related ecosystem technologies and bring new ideas to the team

Experience with relational databases (PostgreSQL) and SQL, including query optimization and schema design
Experience with reactive, non-blocking programming (e.g., Spring WebFlux / Project Reactor); or a strong grasp of non-blocking I/O and backpressure with the ability to ramp quickly
Experience designing and operating event-driven systems using messaging/streaming (e.g., Kafka), including delivery guarantees, idempotency, and schema evolution
Experience integrating heterogeneous systems: resilient service-to-service and third-party integrations, with clean API and error-contract design
Ability to reason from first principles about unfamiliar systems and tradeoffs, not just recall tools and syntax
Familiarity with version control systems (e.g., Git) and collaborative development workflows
Solid understanding of software engineering fundamentals: data structures, algorithms, design patterns
Experience with automated testing (unit/integration) and testing frameworks (e.g., JUnit)




Strong problem-solving skills and ability to debug complex issues
Good communication skills and ability to work effectively in a team environment
Experience with DevOps tools such as Dynatrace or Splunk

Experience with cloud platforms (e.g., AWS, Azure, GCP) and cloud native architectures
