As a Senior Software Engineer in our AI Product Team, you will play a critical role in transforming how analysts process and analyse information. You will work at the forefront of applied AI, building intelligent systems that enhance sense-making, information discovery, and decision-support for national security.

In this role, you will design and develop AI-driven applications, such as retrieval-augmented generation (RAG) systems and intelligent automation workflows, as well as the supporting web systems and data processing pipelines that power these capabilities. You will contribute across the full technology stack, from backend services and data retrieval layers to frontend interfaces that bring AI functionalities to users. Our team focuses on applying and integrating AI technologies rather than model training or fine-tuning, emphasizing innovation, rapid experimentation, and real-world impact.

Responsibilities

Design, develop and deploy scalable AI-enabled digital products integrating retrieval, generation, and reasoning capabilities.
Scout, evaluate, and integrate emerging AI technologies to drive innovation.
Collaborate with analysts, AI engineers, data scientists, designers, and product managers to co-create solutions grounded in organisational needs.
Prototype rapidly and apply engineering best practices to experimental AI applications.
Shape technical strategy for sustainable and intelligent AI systems.
Uphold high software engineering standards, ensuring systems are robust, secure, and interoperable.

Requirements (Minimum Qualifications)

A degree or professional qualification in Engineering, Computer Science, or related fields, with at least 3 years of relevant software development experience.
Strong programming skills in Python, Java, or similar languages, with proficiency in building backend services.
Experience integrating AI models, APIs, or frameworks into applications (e.g., Huggingface, LangChain, OpenAI API, open-source AI models).
Proficiency in frontend development with React or similar frameworks to build intuitive user interfaces for AI-enabled applications.
Solid understanding of system architecture design, software engineering best practices, and scalable service development.
Familiarity with data storage and retrieval technologies like relational databases, vector stores, or search engines.
Hands-on experience with build and deployment tools like Git CI/CD, Docker, and cloud environments.
Good analytical and problem-solving skills, with the ability to translate user needs into technical solutions.
Strong team player who collaborates across disciplines to achieve product goals.

Nice to Have

Interest or experience in rapid prototyping and AI-driven product innovation.
Experience with RAG systems, semantic search, or knowledge graphs.
Familiarity with AI evaluation practices and techniques for improving AI system performance.
Leadership experience in guiding technical teams or driving AI technology adoption.
Knowledge of agile methodologies such as Scrum.
Experience working with Elasticsearch, Neo4j, or similar search and graph databases.

Inside Singapore's push for proactive defence against cyberthreats.

Inside Singapore's push for proactive defence against cyberthreats. Centre for Strategic Infocomm Technologies chief executive Darren Teo said there has been a more proactive sharing of "weak signals", or data that is suspicious but not yet proven to be malicious. Published Oct 09, 2026, 01:01 PM Updated Oct 09, 2026, 05:09 PM SINGAPORE - Singapore's cyberdefenders have continued to encounter attacks by advanced persistent threat (APT) groups since it was publicly revealed in July 2025 that state-sponsored cyberespionage group UNC3886 had infiltrated the city-state's critical information infrastructure (CII). But these attacks are being detected and dealt with more effectively than before through more proactive information-sharing between CII operators, cybersecurity firms and government agencies, said Centre for Strategic Infocomm Technologies (CSIT) chief executive Darren Teo. This greater willingness to collaborate on suspicious network activity that may not cross the threshold into an actual attack - so-called "weak signals" - is crucial as APT groups continue to refine their methods to stay hidden within victims' networks, he added. Teo was speaking to The Straits Times ahead of TechCon 2026 on Oct 9, an annual closed-door conference hosted by CSIT, an agency under MINDEF focused on developing advanced cybersecurity capabilities to safeguard the Republic's digital infrastructure. At the previous TechCon in Oct 2025, Coordinating Minister for National Security K. Shanmugam had announced the setting up of a new digital defence unit within CSIT focused on countering sophisticated cyberthreat actors such as APT groups. One year on, the Digital Defence Hub (DDH) has increased the willingness of the various stakeholders to exchange weak signals early and conduct joint investigations, said Teo. This is a stark change from previous practice, when each part of the industry "more or less stayed in our own lane", he said. For instance, a CII operator used to reach out to its IT vendor only when it encountered a cyber problem.
