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.\n What will you do:\nDesign, build, and operate production-grade agentic and GenAI systems-end to end. You’ll ship services (not just notebooks): robust APIs, reusable components, and secure pipelines that connect LLMs, tools, knowledge, and enterprise systems. You’ll pair strong software engineering with modern AI practices (RAG, agent orchestration, policy chains, evals) to deliver measurable business outcomes at scale.\n1. Agent & Application Engineering\nDesign multi-agent systems (MAS) with planning, tool-use, and delegation (e.g., LangGraph/Semantic Kernel); expose them via REST/gRPC APIs (FastAPI/Express/Java/Go).\nImplement tool adapters (SQL, search, document stores, web calls, code exec) with strict type contracts and safe sandboxes.\nBuild model gateway integrations (OpenAI/Azure OpenAI/Bedrock/Vertex; self-hosted vLLM/TGI) with routing, rate-limits, retries, and fallback chains.\n2. Retrieval, Data & Knowledge\nStand up RAG services: chunking, enrichment, embeddings, indexing, hybrid/vector search (pgvector/Pinecone/Weaviate; OpenSearch/Azure AI Search).\nImplement ingestion pipelines (Airflow/Prefect/Celery/Ray) for docs, tickets, chat, and ERP/CRM data; handle PII redaction and metadata governance.\nOptimize retrieval quality (chunking strategies, re-rankers, query rewriting) with offline/online evaluation and A/B tests.\n3. Quality, Testing & Evaluation\nTreat prompts and graphs as code: version, diff, and test them (unit tests for prompts/tools; golden sets; regression suites).\nBuild evaluation harnesses (latency, cost, accuracy, toxicity, hallucination, guardrail hit-rates); wire into CI.\nAdd drift detection for conversational systems; implement safe shutdown and auto-rollback.\n4. Platform & Operations\nPackage services as containers; deploy to Kubernetes with Helm/Argo CD; configure autoscaling, HPA/VPA, and resource quotas.\nImplement policy chains and guardrails (OPA/Gatekeeper for policy, Presidio for PII, Trivy for image scanning).\nInstrument deep observability: tracing (OpenTelemetry), metrics (Prometheus), logs (ELK/OPENSEARCH), cost meters per request/model.\n5. Security & Compliance\nManage secrets (HashiCorp Vault/KMS), signed images, SBOMs; enforce least-privilege IAM.\nBuild tenant isolation and data residency controls; implement red/blue team prompts and jailbreak defenses.\n6. Integration & Enterprise Workflows\nShip connectors and events for SAP/CRM/ITSM and Kafka topics; design idempotent, retry-safe processors.\nAutomate business workflows with pro-code services first; expose low-code surfaces only where appropriate.\n7. Collaboration & Leadership\nPartner with Product, Data, and Platform teams to define SLAs/SLOs and success metrics.\nMentor engineers on “AI as software” practices; run design reviews and postmortems.\n The ideal candidate should possess:\n6+ years in software engineering (prod services, not just prototypes), including 1+ year leading small projects.\nStrong in one systems language (Python/TypeScript/Go/Java) and comfortable in a second.\nHands-on with containers, Kubernetes, CI/CD (GitHub Actions/GitLab/Jenkins), IaC (Terraform), and cloud (Azure/AWS/GCP).\nPractical LLM experience: building RAG/agent apps, prompt design, tool-use, and safety patterns.\nData skills: designing schemas, batch/stream pipelines, and search indexes; proficiency with SQL and one vector DB.\nTesting mindset: unit/integration tests, load tests, golden datasets for LLM evals.\nSecurity basics: secrets, policies, scanning, and least-privilege IAM.\nPreferred Qualifications\nAgent orchestration (LangGraph, Semantic Kernel) and distributed compute (Ray) in production.\nSearch/retrieval tuning (BM25 + vector hybrid, re-ranking, query planning).\nObservability at scale with OpenTelemetry; cost/perf optimization across model/router layers.\nExperience in regulated or high-throughput domains (e.g., telco, finance, healthcare); multi-tenant and data-residency patterns.\nDomain integrations (SAP/CRM/ITSM), event-driven architectures (Kafka/Debezium), and policy enforcement (OPA/Gatekeeper).\nFamiliarity with TM Forum APIs / BSS-OSS patterns is a plus (if in telco context).\nTech Stack (Illustrative)\n Languages: Python, TypeScript/Node.js (plus Go/Java bonus)\nFrameworks: FastAPI/Express, LangGraph/Semantic Kernel, Ray/Celery, Airflow/Prefect\nStorage/Search: Postgres, Redis, S3/Blob; pgvector/Pinecone/Weaviate; OpenSearch/Azure AI Search\nLLM Runtime: OpenAI/Azure OpenAI/Bedrock/Vertex; vLLM/TGI; inference routers/gateways\nPlatform: Docker, Kubernetes, Helm, Argo CD, Terraform, Vault, Istio\nObservability: OpenTelemetry, Prometheus/Grafana, ELK/OpenSearch\n Quality & Safety: pytest/Jest, prompt/unit test harnesses, guardrails, Presidio, Trivy\n Why Join NCS \nLead high-impact Data & AI advisory programs for major enterprises and public sector clients.\n\nShape enterprise strategies and governance frameworks that drive real transformation.\n\nWork with a talented, multidisciplinary team in a collaborative environment.\n\nCompetitive compensation and strong professional development support.\n\nWe are driven by our AEIOU beliefs-Adventure, Excellence, Integrity, Ownership, and Unity-and we seek individuals who embody these values in both their professional and personal lives. We are committed to our Impact: Valuing our clients, Growing our people, and Creating our future.\nTogether, we make the extraordinary happen.\nLearn more about us at ncs.co and visit our LinkedIn career site.\nScam Alert\nWe are aware of fraudulent job offers and impersonations of NCS recruiters.
