Job description

Company 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

As an AI Engineer who bridges traditional machine learning and modern generative / agentic AI. This role involves designing, building, and deploying end-to-end AI solutions including classical ML models, RAG-based applications, and lightweight agentic workflows. The successful candidate will contribute hands-on to client delivery projects, applying strong Python engineering and statistical rigour to develop scalable AI solutions that work reliably in production environments.

What will you do?

AI / ML Model Development & Deployment

• Design, build, and deploy end-to-end ML models including classification, regression, time-series, and NLP models.

• Integrate ML models into production systems and applications.

• Monitor model performance and conduct analysis to detect data drift, quality issues, and opportunities for improvement.

Generative AI & RAG Application Development

• Develop GenAI applications including RAG pipelines, prompt-engineered chatbots, and lightweight agentic workflows using frameworks such as LangChain, LlamaIndex, LangGraph, or Python.

• Implement effective RAG architectures including chunking strategies, embedding selection, vector store configuration (e.g., Qdrant, Milvus, pgvector), and retrieval evaluation.

Software Engineering & Development Practices

• Write clean, maintainable, and production-ready Python code.

• Participate in code reviews and contribute to shared libraries and internal AI platform components.

• Use Git, CI/CD practices, and containerisation tools such as Docker in development workflows.

Collaboration & Delivery

• Work closely with data engineers, MLOps engineers, and client stakeholders to move AI experiments into reliable production deployments.

• Document technical approaches, solution designs, and experimental results clearly.

Research & Innovation

• Stay up to date with the evolving AI landscape and introduce relevant tools, techniques, and best practices to the team.

Qualifications

The ideal candidate should possess:

• 2-5 years of hands-on experience in AI/ML engineering or data science roles
• Demonstrable track record of delivering at least 2-3 ML projects (beyond notebooks - production or near-production) and 1-2 GenAI / agentic AI projects
• Strong Python programming skills including Pandas, NumPy, Scikit-learn, and PyTorch or TensorFlow
• Solid understanding of machine learning fundamentals including feature engineering, model evaluation, bias-variance trade-off, and hyperparameter optimisation
• Hands-on experience building RAG chatbots and applications using LLM APIs such as OpenAI, Anthropic, AWS Bedrock, Azure OpenAI, or equivalent
• Working knowledge of RAG architecture decisions including chunking strategies, embedding model selection, vector store configuration, and retrieval quality evaluation
• Practical experience with at least one vector database such as Qdrant, Milvus, pgvector, or equivalent
• Experience with at least one cloud platform such as AWS, Azure, or GCP for model training or deployment
• Proficiency with Git, CI/CD basics, and containerisation (Docker)
• Ability to read and write at least one additional programming language such as TypeScript/JavaScript, Java, Go, or advanced SQL

Preferred Skills:

• Experience building voice AI bots using a pro-code approach such as Twilio, Amazon Connect, Deepgram, Whisper + TTS pipelines
• Exposure to agentic patterns such as tool-calling agents, ReAct loops, multi-step planning, or reflection mechanisms
• Familiarity with MLOps tooling such as MLflow, Weights & Biases (W&B), model registries, or orchestration tools like Airflow, Prefect, or ZenML
• Experience with evaluation frameworks for RAG and GenAI outputs such as RAGAS, DeepEval, or promptfoo
• Knowledge of responsible AI principles including bias detection, fairness metrics, and output guardrails
• Exposure to NLP pipelines including entity extraction, text classification, and summarisation
• Prior experience in a systems integrator (SI), consultancy, or multi-client delivery environment
