Senior Java Software Engineer

About the Role: We are seeking an experienced Java Engineer to join our technology modernization team. This role involves transforming a legacy monolithic application, originally developed in a proprietary language transpiled to Java, into modular, scalable, and maintainable Java microservices. The candidate will be responsible for the full lifecycle of the new microservices, from initial design to deployment, containerizing them for both on-premises and cloud environments.

Responsibilities:

• Analyze legacy monolithic applications written in proprietary languages, and design strategies for decomposing and re-architecting into Java microservices.
• Develop, test, and deploy high-quality, robust Java-based microservices adhering to best practices and standards.
• Containerize applications using Docker and manage deployments through Kubernetes, ensuring compatibility with both on-premises and cloud infrastructures, particularly Azure.
• Collaborate with architects, business analysts, and quality assurance teams to ensure the new services meet business requirements and technical standards.
• Write comprehensive unit, integration, and performance tests to guarantee the reliability and scalability of the services.
• Participate actively in agile development processes, including sprint planning, retrospectives, and code reviews.
• Proactively troubleshoot and optimize performance bottlenecks and complex technical issues.
• Mentor junior developers and contribute to technical documentation and training materials.

Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or related technical field, or equivalent practical experience.
• 5+ years of professional Java software development experience, ideally using Java 11 or newer.
• Proven experience migrating legacy monolithic systems into modern microservices-based architectures.
• Solid expertise with containerization (Docker) and orchestration technologies (Kubernetes).
• Experience deploying applications both on-premises and to cloud environments, especially Azure (Azure Kubernetes Service, Azure App Services, Azure Functions).
• Familiarity with proprietary language transpilers or code interpreters and the processes for translating such code to Java is advantageous.
• Previous experience in commercial lending or related financial services domains is a significant plus.

Skills and Competencies:

• Deep understanding of modern microservices architectures, RESTful API design, and event-driven systems (e.g., Kafka, RabbitMQ).
• Strong proficiency in best practices for software development, including test-driven development (TDD), behavior-driven development (BDD), continuous integration/delivery (CI/CD), and SOLID principles.
• Experienced with relational and non-relational databases (SQL Server, PostgreSQL, MongoDB) and ORM frameworks (Hibernate, Spring Data).
• Competent in performance optimization and application monitoring tools.
• Comprehensive knowledge of secure coding practices and principles related to authentication, authorization, and data encryption.
• Excellent analytical, problem-solving, and debugging abilities.
• Exceptional communication skills, able to articulate technical concepts clearly to both technical and non-technical stakeholders.
• Proven effectiveness in agile and collaborative team environments, adapting well to evolving project priorities.
