We are looking for 10+years experienced candidates for this role.

Job Description

The Senior Java Architect is responsible for designing, developing and overseeing the architecture of enterprise-level Java applications. This role ensures that systems are scalable, high-performing, and secure by leveraging modern Java frameworks and best practices. The Java Architect will collaborate with cross-functional teams to integrate various technologies (such as messaging, caching, databases, api gateways, security infrastructures, workflow engines, deployment mechanisms etc) into a cohesive solution and guide developers in implementing robust, maintainable code.

Certifications :

• Oracle Certified Master, Java Enterprise Architect (OCMJEA)
• Oracle Certified Professional Java Programmer/Developer
• Certified Kubernetes Application Developer (CKAD)

Primary Skills :

MUST HAVE

Core Responsibilities

• Define the overall architecture for Java-based applications, including the use of microservices, APIs, and integration patterns to meet business requirements.
• Select and govern the use of Java frameworks (for example, Spring Boot, Spring Security, Hibernate/JPA) to ensure consistency and quality across projects.
• Lead the end-to-end modernization of a mission-critical on-premises platform, ensuring near zero data loss and minimal downtime during migration.
• Design and deliver solutions that can run alongside existing systems, support phased rollout across multiple data centres and a DR site, meet strict uptime and performance SLAs, and align with existing monitoring and integration mechanisms.
• Collaborate with Database and Infrastructure teams to define how applications interact with databases and run in containerized environments (for example, Oracle Database for OLTP and Redis for caching).
• Establish coding standards, conduct code reviews, and mentor development teams on best practices for error handling, logging, and secure coding.

Technical Skills

• Expert-level proficiency in Java (Java SE/EE, ideally including recent versions) and in-depth knowledge of the Java ecosystem.
• Strong experience with Java frameworks and libraries: Spring Boot for microservices, Spring Security for authentication and authorization, Hibernate/JPA for ORM, and related tools.
• Hands-on experience designing and implementing microservices architectures and RESTful APIs, including inter-service communication patterns and API documentation (OpenAPI/Swagger).
• Solid understanding of relational databases, especially Oracle database design and SQL.
• Strong understanding of API security and authentication/authorization mechanisms (for example, OAuth2, OpenID Connect, JWT).

Experience and Soft Skills

• 10+ years of experience in software development with at least 2–3 years in an architect role focused on Java applications.
• Proven track record in designing and delivering large-scale, distributed systems and enterprise applications using Java technologies.
• Strong leadership in guiding development teams, conducting design reviews, and driving architectural governance.
• Excellent communication skills, with the ability to explain complex technical concepts to stakeholders and produce clear architectural documentation and diagrams.

SHOULD HAVE

Responsibilities

• Design integration solutions using enterprise messaging and API management tools (for example, implementing event streaming with Apache Kafka and using API gateways such as IBM API Connect for external integrations).
• Work closely with DevOps teams to integrate build and deployment pipelines (for example, Azure DevOps or Jenkins) and containerization platforms (such as Docker and OpenShift) into the development lifecycle.
• Monitor and troubleshoot the architecture during development and testing, and address performance bottlenecks or security vulnerabilities using monitoring tools, logs, and APM solutions.

Technical Skills

• Knowledge of messaging and streaming platforms like Apache Kafka to support event-driven architecture.
• Experience with caching and session management solutions (for example, Redis or in-memory grids) to improve performance and scalability.
• Experience with API gateway products (such as IBM API Connect) for managing internal and external APIs.
• Proficiency with DevOps and deployment tooling: Git for source control, CI/CD pipelines (Azure DevOps Pipelines or Jenkins), Docker for containerization, and Kubernetes/OpenShift for orchestration.
• Knowledge of monitoring and logging frameworks and tools (for example, Elastic Stack/ELK for log aggregation and APM tools like Dynatrace) to ensure the health and performance of Java applications in production.

Experience

• Experience optimizing application performance, including profiling Java applications, tuning garbage collection, and applying caching strategies to achieve high throughput and low latency.
• Prior involvement in secure software development practices, including integrating static code analysis or vulnerability scanning into the development process, and familiarity with DevSecOps concepts.

Secondary Skills :

NICE TO HAVE

Technical Skills and Experience

• Exposure to NoSQL or multi-model databases and the ability to choose the appropriate data storage technology for specific use cases.
• Experience with reactive frameworks or newer JDK features that can improve responsiveness and scalability.
• Broader experience with different API gateways, logging stacks, and APM tools beyond those explicitly mentioned.
