Role Overview
We are looking for a Principal Architect, Data & AI/ML who is equally comfortable whiteboarding an enterprise data strategy and rolling up their sleeves to write production-grade code, design reference architectures, and mentor delivery teams. This is a hands-on leadership role that sits at the intersection of data engineering, machine learning engineering, and solution architecture.
You will serve as the technical anchor across client engagements — owning architecture decisions end-to-end, driving pre-sales pursuits, and building reusable accelerators that amplify the practice's delivery capability. The ideal candidate has deep expertise across the full data & AI/ML value chain — from data foundations to decision intelligence.

Key Responsibilities
Solution Architecture & Technical Leadership
Design and own end-to-end reference architectures for data platforms, lakehouses, AI/ML pipelines, and GenAI products across multi-cloud environments (AWS, Azure, GCP).
Lead architecture reviews, proof-of-concepts, and technical due-diligence for client engagements.




Define architectural principles, design patterns, and guardrails for the practice; contribute to CriticalRiver's internal IP and accelerator library.
Translate business requirements into scalable, cost-optimised, and secure technical blueprints.
Generative AI & LLM-Ops
Architect and build enterprise-grade Generative AI solutions using large language models (LLMs), retrieval-augmented generation (RAG), vector databases, and AI agents.
Design LLM-Ops pipelines covering fine-tuning, prompt engineering, evaluation harnesses, guardrails, and model observability.
Enable "no-data" and "agents-on-data" patterns — embedding AI agents into structured data workflows and decision processes.
Data Engineering & Integration
Architect up-to-date data integration pipelines: batch, micro-batch, and real-time; ELT/ETL on cloud-native platforms.
Lead lakehouse and warehouse modernisation engagements — design migration patter
