Summary:

WTW is seeking an experienced Production Support Software Engineer specializing in Java, Angular, and Oracle technologies to join our growing IT Operations and Production Support team in Kolkata. This position combines production application support with hands-on software engineering. You will investigate Benefits Accounts application issues, analyze logs and service behavior, develop fixes for software defects, and implement small, well-defined application enhancements in partnership with the product and domain development teams.

The application environment includes Java, Spring or Spring Boot, Angular, Oracle, REST APIs, integrations, and microservices or service-oriented components.

The role’s primary focus is bug fixing and small feature development, followed by production investigation and troubleshooting. The owning domain development team retains responsibility for functional testing, release approval, production deployment, major feature development, and leadership of high-severity incidents.

Responsibilities:

• Investigate production application issues using application logs and approved diagnostic tools.
• Analyze Java exceptions, REST APIs, Angular application behaviour, service integrations, and unexpected application results.
• Trace application behavior across Angular front-end components, Java services, APIs, integrations, and downstream dependencies.
• Develop evidence-based findings and identify the appropriate owning team.
• Distinguish between application, configuration, integration, infrastructure, database, and data-related issues.
• Reproduce software defects and develop safe, focused code corrections.
• Create source-code branches and pull requests, add appropriate unit tests, and participate in code reviews.
• Implement small, well-defined enhancements with documented acceptance criteria and approval from the owning product or domain team.
• Provide completed code changes to the Benefits Accounts domain team for functional testing, release approval, and production deployment.
• Participate primarily in lower-severity incident investigations and provide application-engineering escalation support when needed.
• Assist with higher-severity investigations when requested, while the owning domain and incident-management teams retain leadership responsibility.
• Coordinate with authorized teams when production Oracle database investigation is required.
• Document investigation findings, probable cause, code changes, testing considerations, risks, and handoff information.
• Collaborate with IT Operations, Product, and Engineering colleagues in India and the United States.
• Use approved AI-assisted development tools to improve investigation, coding, and testing productivity while maintaining security, quality, testing, and code-review standards.

Requirements:

• 7+ years of software development, production application support, or a combination of both.
• Strong software-development experience using Java.
• Experience with Spring, Spring Framework, or Spring Boot.
• Working knowledge of Angular and modern front-end application development.
• Experience developing and troubleshooting REST APIs, web applications, service integrations, and downstream dependencies.
• Knowledge of Oracle SQL and relational database concepts.
• Experience with microservices or service-oriented application architectures.
• Strong understanding of object-oriented design and software-engineering principles.
• Strong application-investigation and problem-solving skills.
• Experience analyzing application logs, exceptions, error messages, and service behavior.
• Ability to trace application behavior across multiple services and develop an evidence-based probable cause.
• Ability to distinguish between application, integration, configuration, infrastructure, database, and data issues.
• Ability to identify and engage the appropriate owning team.
• Ability to reproduce software defects and translate investigation findings into safe, focused code changes.
• Experience writing and maintaining unit tests using JUnit, Mockito, or comparable testing tools.
• Experience with Git-based source control, branches, pull requests, and code reviews.
• Ability to work effectively when direct production database access is unavailable.
• Strong written and verbal communication skills.
• Ability to create clear technical documentation and handoff information.
• Experience collaborating with geographically distributed teams.
