Job Description
We're seeking a hands-on Senior Java Engineer to design, build, and operate high-performance microservices and platform components. You'll own core backend services, drive cloud-native deployments on Azure, and contribute to our CI/CD and observability initiatives. This role requires strong Java expertise, experience with Spring Boot, security, containerization, and a solid understanding of multi-environment deployments.
Key Responsibilities
Design, develop, and maintain scalable microservices using Java/J2EE and Spring Boot (Spring MVC, Spring Security).
Implement secure authentication/authorization (OAuth2, JWT) and protect APIs across services.
Architect and implement multi-environment deployment strategies (dev/stage/prod) on Azure; leverage AKS, App Service, Cosmos DB, Key Vault, and other Azure services as appropriate.
Containerize applications with Docker and deploy and manage workloads in Kubernetes and OpenShift.
Build and maintain robust CI/CD pipelines (Jenkins, Maven/Gradle) with automated testing, static code analysis, security checks, and blue/green or canary deployments.
Integrate with external services and third-party APIs; design resilient patterns (retries, circuit breakers, bulkheads) and secure API gateways.
Implement observability and incident response practices: centralized logging (ELK/EFK), metrics (PrometheGrafana), distributed tracing (OpenTelemetry), and dashboards.
Collaborate with product, frontend, and DevOps teams in an Agile/Scrum environment; drive design reviews, code quality, and best practices.
Mentor junior engineers, contribute to architecture decisions, and continuously improve development and deployment processes.

- Proficient in CI/CD with Jenkins and build tools (Maven/Gradle); experience with test automation and code quality tooling.
- Solid understanding of software security, authentication/authorization, and secure coding practices.
- Experience with external service integrations (REST/SOAP, messaging queues, payment gateways).
- Familiarity with observability stacks (ELK/EFK, PrometheGrafana) and distributed tracing (OpenTelemetry).
- SQL and data modeling skills; comfortable with ORMs (Hibernate, JPA) and database tuning.
- Excellent problem-solving, communication, and collaboration skills.
Desired Qualifications
- Experience with Azure DevOps or other DevOps tooling.
