Innovation & R&D: Evaluate emerging technologies, frameworks, and methodologies, conducting proof-of-concepts (PoCs) to strategically introduce them into our programme.
What to expect: Design, develop, and maintain software applications: Write clean, scalable, and efficient code to create software solutions that meet user needs. Build scalable contact data pipelines: Develop robust data ingestion, deduplication, and segmentation logic for contact management at scale. Collaborate with cross-functional teams: Work closely with product managers, designers, and other engineers to deliver high-quality citizen-centric products. Participate in code reviews: Ensure code quality and share knowledge with team members to improve overall team performance. Debug and troubleshoot issues: Identify and resolve software defects and performance issues. Implement automated testing and continuous integration: Ensure the reliability and stability of the software through automated tests and CI/CD pipelines. No dedicated QE on the team, so you own quality end-to-end. Documentation: Create and document technical designs that are aligned with architectural guidelines. Integrate with downstream platforms: Connect ContactSG with communication channels (email, SMS, etc.) used by agencies. Stay updated with the latest industry trends: Continuously learn and apply new technologies and best practices to improve our products. Act as a technical lead when required: Drive technical direction, make architectural decisions, and ensure alignment with best practices and business goals.Experiences we look out for: At least 5 years of relevant working experience in software development, preferably in full stack web development. A degree in Computer Science or a related field is preferred. Possess a strong understanding of computer science fundamentals, including data structures, algorithms, programming skills, and software design principles and patterns. Proficient in full stack development with hands-on experience using technologies such as React, Node.js, and PostgreSQL. Experience with CI/CD pipelines, automated testing, and DevOps practices. Familiarity with cloud services, with added advantage for experience in AWS services. Demonstrated strong ability to write clean, maintainable, and efficient code in a collaborative environment. Experience with data lakes and large-scale data processing is a plus. Familiarity with record matching and deduplication techniques is a plus. Background in CRM, contact management, or customer data platforms is a plus. Experience with Kotlin is a plus (to support legacy codebases).
Assist in investigating feasible optimization suggestions for existing quality and efficiency pain points of the engineering and algorithm teams, and drive the implementation of solutions to improve delivery quality and efficiency.
When incidents occur, you will lead triage and debugging within your domain, contribute root cause analyses, and drive concrete preventive actions through post-incident reviews.
Use AI-assisted engineering tools and workflows, such as Claude Code, spec-driven development, reusable skills, and automated review/test loops, to accelerate delivery while preserving engineering quality.
Exposure to client-side development, backend systems, audio/video technologies, and AI agent engineering, giving you a broad and well-rounded technical perspective.
