• Perform functional, integration, and system testing to ensure application changes meet business and technical requirements.
• Diagnose software defects and production incidents, identify root causes, and implement effective technical solutions.
• Review application designs and source code to improve software quality, maintainability, stability, and performance.
• Develop and maintain integrations with internal and external systems through APIs, databases, messaging interfaces, and financial connectivity protocols.
• Work closely with development, testing, infrastructure, operations, and business teams during project delivery and incident resolution.
• Support the modernization of applications through microservices, containers, cloud platforms, and other contemporary engineering practices.
• Assist with production releases, post-implementation verification, and system stability monitoring.
• Participate in scheduled production support outside standard office hours, including occasional overnight, weekend, or public holiday coverage.
• Take ownership of additional system development or technology improvement initiatives when required.

Candidate Profile

• Bachelor’s degree in Computer Science, Information Technology, Software Engineering, or another relevant discipline.
• At least 10 years of experience in software engineering or enterprise application development.
• Demonstrated experience delivering large-scale, high-availability, or business-critical technology platforms.
• Strong hands-on programming capability in Java.
• Solid practical experience working with Linux operating environments.
