Senior Microservices Developer

MustHave Skills

• Java (preferably Java 17+) with strong OOP, collections, and concurrency fundamentals.
• Spring ecosystem (Spring Boot, MVC, Data/JPA, Security),
• Hibernate ability to design and build scalable microservices. Eventdriven architecture with Kafka (producers/consumers, schema/serialization, stream processing basics).
• API development (REST gRPC/Protobuf exposure ideal) including API Gateway patterns secure auth (JWT) and CSRF protection
• Cloud deployment on AWS (ECS, EC2, RDS, ElastiCache) and Infrastructure as Code (CloudFormation)
• Containers & Orchestration: Docker and Kubernetes/Openshift for build, deploy, and runtime operations.
• CI/CD with Jenkins Gitbased workflows pullrequest reviews.
• Testing discipline (JUnit, Mockito comfortable with TDD and 80%+ coverage expectations).
• Databases: solid SQL with PostgreSQL/MySQL/Oracle basic schema design, indexing, and query optimization.

GoodtoHave Skills

• CQRS and circuitbreaker/resiliency patterns rate limiting at API gateway level.
• Spring Batch for scheduled/batch processing, Quartz job scheduling.
• Security hardening (encryption/decryption of sensitive data static analysis with SonarQube Veracode familiarity)
• Messaging/JMS, IBM MQ healthcare messaging (HL7) exposure. Experience across payments/banking/healthcare domains and
• large enterprise environments (JBoss/WebLogic/Tomcat)

Roles & Responsibilities

• Design & build highthroughput, lowlatency microservices in Java/Spring drive API design (REST/gRPC) and contract standards
• Lead technical delivery across the SDLC: solutioning, estimation, implementation, integration, and production readiness
• Implement eventdriven systems with Kafka (topic design, consumer groups, offsets, error handling, retries, deadletter strategies).
• Harden security (JWT, CSRF, encryption of sensitive fields) enforce secure coding practices and peer reviews.
• Optimize performance (Redis caching, pagination strategies, profiling SLAdriven tuning)
• Automate build & deploy with Jenkins pipelines and containerized delivery to Kubernetes/Openshift champion IaC for environments. Instrument observability (Prometheus/Grafana/Dynatrace dashboards, alerts, SLOs) perform rootcause analysis for incidents
• Maintain code quality via TDD, unit/integration tests (JUnit/Mockito), static analysis (SonarQube), and secure scans (Veracode).
• Collaborate crossfunctionally with product, security, QA, and frontend teams (Angular/React) to deliver cohesive features and UX.
• Mentor junior engineers conduct design/code reviews and contribute to engineering best practices.
