In this role, you will be expected to make sound engineering trade-offs in a legacy environment where data integrity, security, auditability and service continuity are critical. You should be comfortable working with large and complex codebases, investigating difficult defects, understanding business rules embedded in older implementations, and helping the team move progressively toward better engineering practices and future-state architecture.

What we are looking for

• Degree in Computer Science, Software Engineering, Information Systems or a related discipline, or equivalent practical experience.
• At least 3–5 years of relevant experience in software engineering, application maintenance, or enterprise system development.
• Strong programming and debugging skills, with experience in one or more of the following: Java, JSP, JavaScript, SQL, PL/SQL, shell scripting, or related enterprise technologies.

• Experience with software delivery practices such as version control, CI/CD, automated testing, release management and environment management.
• Working knowledge of secure coding principles and application security practices, with appreciation of vulnerability remediation and operational risk management.
• Good analytical thinking and problem-solving ability, with a disciplined approach to change impact assessment and root cause analysis.
• Strong communication and collaboration skills, with the ability to work effectively with technical and non-technical stakeholders.
• Ability to learn quickly, take ownership of assigned work, and contribute in a structured, high-accountability environment.

Preferred qualifications

• Experience with legacy modernisation, technology refresh, code recovery, refactoring or migration initiatives.
• Experience with Oracle, WebLogic, IIS, Tomcat, Spring Boot, Angular, AWS GCC, or similar enterprise platforms.
• Exposure to DevSecOps, observability, performance monitoring, resiliency engineering or platform security controls.
• Experience in highly regulated, high-availability or public sector environments where auditability, compliance and operational continuity are important.
• Experience supporting systems with external agency or business partner integrations.
• Practical experience using AI-assisted engineering tools in a disciplined and governed way to improve delivery outcomes.
• Familiarity with land, registry, legal, transactional or document-centric systems will be an advantage.

This is a meaningful opportunity to work on systems that are foundational to Singapore’s land administration and property transaction ecosystem.

You will help keep critical legacy platforms dependable today while shaping their next phase of modernisation, resilience and AI-enabled transformation for the future
