Job description

NCS is a leading AI Tech Services company. With a 15,000-strong team across the Asia Pacific, NCS scales its platforms and capabilities to provide clients with greater agility and AI expertise across a range of Industries. Embracing a strong ecosystem of global partners, NCS transforms technology services delivery combining AI with digital resilience to drive real business impact. NCS is a subsidiary of the Singtel Group.

Job Description

We are looking for an AI Developer to play a key role in building our agentic reasoning engines. You will own the intelligent layer of our bespoke enterprise system, ensuring our AI agents are reliable, secure, and capable of solving complex workflows. You will be involved in developing sophisticated RAG capabilities and stateful multi-agentic networks, moving beyond simple chat to high-consequence autonomous systems.

What will you do?

• Agentic AI Architecture & Development
• Design and implement stateful multi-agent networks and/or workflows using LangGraph and/or LangChain.
• Architect and implement multi-layered guardrails to ensure agent actions remain within business scope, enterprise safety and policy boundaries.
• Build guardrails to mitigate risks such as prompt injection and data leakage.
• Develop sophisticated reasoning engines capable of handling complex, high-consequence autonomous workflows.
• RAG Pipeline Development & Optimisation
• Build and optimise end-to-end RAG (Retrieval-Augmented Generation) pipelines, focusing on high-precision retrieval and semantic search.
• Integrate diverse data sources including vector DB, graph DB, NoSQL, and RDBMS.
• Implement advanced RAG techniques such as chunking strategies, query expansion, re-ranking, and hybrid search.
• Apply prompt engineering and context engineering techniques to enhance retrieval quality.
• AI Microservices & Deployment
• Build and maintain high-performance AI microservices optimised for OCI-compliant environments.
• Serve AI agents via FastAPI, packaging and deploying in OCI-compliant environments and OCP (OpenShift Container Platform).
• Implement semantic caching and design for parallel LLM invocation to optimise performance.
• Integrate AI evaluation into CI/CD pipelines (e.g., Jenkins, GitLab CI).
• Performance Monitoring & Evaluation
• Use LLM evaluation frameworks to quantitatively measure agent performance.
• Leverage AI tracing, observability, and logging tools to identify and fix bottlenecks in complex reasoning paths.
• Monitor and continuously improve agent reliability, accuracy, and efficiency.
• Cross-Functional Collaboration
• Partner with software teams to define data contracts and integrate information flow from AI layer to software backend and frontend.
• Collaborate with stakeholders to ensure AI solutions align with business objectives and technical requirements.
• Communicate effectively (written and verbal) with technical and non-technical stakeholders at all levels.

Qualifications

An ideal candidate should posses:

Technical Requirements

• Expert-level proficiency in Python, specifically for asynchronous AI applications.
• Mastery of LangGraph and LangChain for building production-grade, stateful systems with human-in-the-loop verification patterns.
• Proven success in developing RAG capabilities, including experience with chunking strategies, advanced techniques like query expansion, re-ranking, hybrid search, etc.
• Deep hands-on experience with vector DB, graph DB, NoSQL, and RDBMS.
• Experience building guardrails to mitigate risks such as prompt injection and data leakage.
• Experience integrating AI evaluation into CI/CD pipelines (e.g., Jenkins, GitLab CI).
• Experience serving AI agents via FastAPI, packaging and deploying in OCI-compliant environments and OCP.
• Proficiency in AI tracing, observability, and logging tools to identify and fix bottlenecks in complex reasoning paths.
• Experience implementing semantic caching and designing for parallel LLM invocation.
• Knowledge of prompt engineering and context engineering techniques.

Professional Experience

• At least 2–5 years of experience in AI/ML development, with substantial work in production-grade agentic AI systems.
• Proven track record of deploying AI solutions in enterprise environments.
