About the Role

We are looking for a seasoned backend engineer to design, build, and scale distributed, event-driven systems using Java, Spring Boot, Kafka, and AWS. You will own the architecture of critical services, set engineering standards, and mentor engineers while staying hands‑on in the code.

Responsibilities

• Design and build scalable, secure backend services using Core Java and Spring Boot.
• Architect microservices, defining service boundaries, data ownership, and communication patterns.
• Develop RESTful APIs with clear contracts, versioning, security, and OpenAPI documentation.

• Deploy and operate services on AWS (ECS/EKS, Lambda, S3, RDS/DynamoDB, SQS/SNS, MSK, IAM, CloudWatch).
• Drive resilience with circuit breakers, retries, idempotency, and graceful degradation.
• Troubleshoot complex production issues, including JVM tuning and heap and thread dump analysis.
• Lead design and code reviews, produce architecture documents, and mentor engineers.
• Champion CI/CD and automated testing (unit, integration, contract, performance).

Required Qualifications

• 7+ years of backend software engineering experience.
• Deep experience with Spring Boot and the Spring ecosystem (Data/JPA, Security, Cloud).
• Strong REST API design experience, including OAuth2 and JWT.
• Proven delivery of microservices in production.

• Proficiency with JUnit, Mockito, Testcontainers, Docker, Git, Maven/Gradle, and CI/CD tools.
• Strong communication and technical leadership skills.

Preferred Qualifications

• Kubernetes, Terraform or CloudFormation.
• Observability tools (Prometheus, Grafana, ELK, Datadog).
• Experience with AI-assisted development tools.
