Principal Architect AI Data Engineer

Key Responsibilities

Architecture & Solution Leadership

• Lead the design of enterprise-grade GenAI and agentic architectures (single-agent, multi-agent, tool-driven systems).
• Define reference architectures, reusable frameworks, and best practices for LLM applications across the organisation.
• Architect and oversee implementation of end-to-end RAG pipelines: 
  • Data ingestion → chunking → embeddings → vector search → orchestration → response synthesis.
• Drive scalability, reliability, cost optimisation, and performance across GenAI platforms.

Agentic & LLM Engineering (Hands-on + Oversight)

• Provide technical leadership in prompt engineering, prompt orchestration, and agent workflows (LangChain, LangGraph, etc.).
• Guide teams on tool-calling, function-calling, memory handling, and multi-agent system design.
• Lead efforts in hallucination reduction, guardrails, safety mechanisms, and output evaluation frameworks.

Platform & Engineering Excellence

• Architect production-grade APIs and services (FastAPI/Flask/enterprise microservices) for LLM solutions.
• Define MLOps / LLMOps pipelines including CI/CD, monitoring, observability, and evaluation.
• Partner with Data Engineering teams to ensure: 
  • Data quality, lineage, governance, and compliance
  • Seamless integration with enterprise data platforms

Organisation-Level Responsibilities (Critical)

Capability Building & CoE Development

• Build and scale GenAI / Agentic AI Centre of Excellence (CoE).
• Define standardised frameworks, accelerators, and reusable components to improve delivery velocity.
• Drive organisation-wide adoption of GenAI best practices and tooling standards.

Strategic & Stakeholder Leadership

• Engage with CXOs, business stakeholders, and clients to translate business problems into AI-led solutions.
• Lead solutioning, pre-sales, RFP responses, and client workshops for GenAI opportunities.
• Influence AI strategy, roadmap, and investment decisions at organisational level.

Governance, Risk & Compliance

• Establish enterprise governance frameworks for GenAI: 
  • Responsible AI, security, privacy, ethical usage, and compliance
• Define policies for: 
  • Data access, redaction, model usage, auditability, and explainability

Mentorship & Team Leadership

• Mentor and guide architects, engineers, and data scientists.
• Drive technical upskilling, hiring strategy, and capability maturity.
• Review solution designs and enforce architecture quality standards.
