Responsibilities

• Design and build LLM-powered applications across models (Claude, GPT-4, Gemini, or open-source) based on latency, cost, and quality tradeoffs.
• Build and optimise RAG pipelines connecting LLMs to enterprise knowledge sources.
• Develop AI agents and multi-agent systems using LangChain, LangGraph, CrewAI, or LlamaIndex.
• Create evaluation harnesses to measure output quality, faithfulness, latency, and cost across models.
• Implement system-level prompt engineering, guardrails, and red-teaming for safe AI behaviour.
• Integrate workflow automation platforms to extend AI capabilities into business operations.
• End-to-end delivery of high-performance full-stack applications (React/Next.js frontend with Python/Node backend).
• Design robust microservices and APIs with clean architecture; implement OAuth 2.0, JWT, RBAC.

Job description

About The Role

We are looking for a Full Stack AI Engineer to design, build, and operate AI-powered applications that solve real business problems — in production, not demos. This role combines production-grade software engineering with modern AI capabilities: LLMs, RAG pipelines, AI agents, and secure cloud deployment.

About The Role

We are looking for a Full Stack AI Engineer to design, build, and operate AI-powered applications that solve real business problems — in production, not demos. This role combines production-grade software engineering with modern AI capabilities: LLMs, RAG pipelines, AI agents, and secure cloud deployment.

What You'll Do

AI & LLM Engineering

• Design and build LLM-powered applications using models such as Claude, GPT-4, Gemini, or open-source equivalents (Llama, Mistral), selecting the right model based on latency, cost, and quality tradeoffs.
• Build and optimise RAG pipelines connecting LLMs to enterprise knowledge sources; own chunking strategy, retrieval quality, and embedding model selection.
• Develop AI agents and multi-agent systems using frameworks such as LangChain, LangGraph, CrewAI, or LlamaIndex; design for the failure modes specific to agentic workflows.
• Build evaluation harnesses that measure output quality, faithfulness, hallucination rate, latency, and cost across model versions and prompt changes — governing whether AI features ship or roll back.
• Implement prompt engineering at the system level, including guardrails, output filtering, and red-teaming to ensure safe and reliable AI behaviour.
• Integrate workflow automation platforms (e.g. n8n, Make, Power Automate) to extend AI capabilities into business operations.

Full Stack Development

• End-to-End Delivery: Build and maintain high-performance full-stack applications, coupling responsive front-ends (React/Next.js) with production-grade backend services.
• Backend Architecture: Design, build, and operate robust microservices and APIs using Python (FastAPI/Django) or Node.js, strictly adhering to clean architecture principles.
• API Design & Identity: Architect secure RESTful and GraphQL APIs. Implement OAuth 2.0, JWT (including rotation and revocation strategies), robust session management, and Role-Based Access Control (RBAC).
• Database Engineering: Design and optimize PostgreSQL schemas for high-throughput workloads. Drive strategies for normalization, indexing, query optimization, migrations, connection pooling, and read-replicas/partitioning.
• Asynchronous Systems: Build event-driven architectures leveraging queues, pub/sub messaging, and background workers to decouple services and ensure seamless scalability.

Cloud, DevOps & Mass-Scale Deployment

• Cloud Infrastructure: Deploy and operate production services on Microsoft Azure (essential), with AWS or GCP experience considered highly advantageous.
• Compute Strategy: Architect scalable serverless solutions (Azure Functions, AWS Lambda) alongside containerized workloads, deliberately selecting the optimal compute model per task.
• Container Orchestration: Manage Docker and Kubernetes environments, handling deployments, autoscaling (HPA/VPA), service mesh integration, and advanced release strategies (rolling, blue-green, canary).
• Infrastructure as Code: Provision and version cloud environments repeatably across dev, test, and production utilizing Terraform or Bicep.
• High Availability & Scale: Architect for mass-scale resilience. Ensure multi-region failover, sophisticated load balancing, auto-scaling under variable load, zero-downtime deployments, and robust capacity planning.
• CI/CD & Observability: Build automated deployment pipelines with embedded testing, security scanning, and secrets management. Own production reliability through comprehensive tracing, alerting, and root‑cause incident response.

Security & Authentication

• Zero-Trust Identity: Drive end-to-end authentication and authorization (OAuth 2.0/OIDC, JWT), enforcing secure session handling, RBAC/ABAC, and strict secrets management.
• Proactive Security: Conduct threat modeling and secure code reviews. Integrate SAST/DAST tooling into CI/CD pipelines to intercept vulnerabilities prior to deployment.
• Data Protection: Implement robust encryption at rest and in transit, securing data storage and enforcing stringent access controls across all databases and services.
• Application Hardening: Apply OWASP Top 10 principles across the entire stack, fortifying APIs against common attack vectors like injection, broken authentication, and excessive data exposure.

AI & Emerging Tech (Advantageous, not essential)

• AI Integration: Leverage LLM-powered applications and AI agent frameworks (e.g., LangChain, LangGraph) to enhance platform capabilities.
• Strategic Alignment: Integrate AI‑adjacent services seamlessly into the broader architecture to support and accelerate RSGx's internal AI programme.

Collaboration & Delivery

• Technical Scoping: Translate complex stakeholder requirements into elegant technical solutions. Constructively push back when proposed approaches add complexity without delivering tangible business value.
• Cross-Functional Execution: Collaborate seamlessly across product, data, and business teams to consistently deliver projects on time.
• Engineering Leadership: Mentor peers, conduct rigorous code reviews, and actively contribute to elevating the team's engineering standards and best practices.

What We're Looking For Education & Experience

• Bachelor's Degree in Computer Science, Software Engineering, Data Science, or a related field.
• 8-10 years of software development experience in a production environment.
• Demonstrable hands‑on experience with Microsoft Azure — including compute, networking, IAM, and Azure-native AI services (Azure OpenAI, Azure ML, Azure AI Foundry).
• 1+ year of hands‑on experience building and deploying AI/LLM applications.

Preferred Qualifications

• Experience building and operating AI agent and multi-agent systems.
• Experience integrating AI into enterprise applications at scale.
• Knowledge of MLOps practices: model versioning, monitoring, drift detection.
• Deep experience with Azure AI services: Azure OpenAI Service, Azure Machine Learning, Azure AI Foundry, and Azure Cognitive Services.
• Familiarity with workflow automation tools: n8n, Make, Zapier, or Power Automate.
• Exposure to data engineering and ETL pipelines.
• Familiarity with AI safety practices: output guardrails, adversarial testing, LLM-as-judge evaluation.

What Strong Candidates Demonstrate

Beyond credentials, we look for engineers who can:

• Describe a specific production failure in an AI system they owned — the failure mode, and what they built to prevent it recurring.
• Walk through a RAG pipeline they shipped: retrieval quality before and after a meaningful improvement, and the metric used to measure it.
• Articulate when not to use an LLM — and what simpler approach they chose instead.
• Explain a security decision they made in an API or cloud deployment: the threat they were mitigating and why they chose that control.

What We Offer

• Direct involvement in enterprise AI implementations, from architecture to production.
• Exposure to a modern AI stack across multiple cloud platforms and LLM providers.
• Collaborative team environment with meaningful technical ownership.
• Hybrid working arrangements in Kuala Lumpur.
• Clear career growth path in a discipline with strong market demand.
