We are looking for an experienced AI Architect to design enterprise-grade AI solutions and bridge business strategy, enterprise architecture and technology innovation. You will translate business requirements into end-to-end AI architectures and reusable architecture patterns, guiding initiatives from proof of concept (PoC) through production to scale. Your expertise will span Generative AI, large language models (LLMs), Agentic AI, retrieval-augmented generation (RAG), Machine Learning, Data Engineering and cloud platforms, with a focus on scalability, resilience, security and Responsible AI.

Your Key Responsibilities:

• Define end-to-end enterprise AI architectures aligned with business strategy, enterprise architecture and technology innovation.
• Design AI solution architectures spanning Generative AI, LLMs, Agentic AI, RAG, Machine Learning, Data Engineering and cloud platforms.
• Translate business requirements into architecture blueprints and reusable patterns covering APIs, integration, data flows and supporting infrastructure.
• Guide AI initiatives from proof of concept through production to scale, ensuring architectural consistency across the AI/LLM lifecycle.
• Design scalable, resilient and secure AI architectures, including APIs, integration and supporting cloud infrastructure.
• Define architectural requirements for MLOps/LLMOps, observability, evaluation, security and Responsible AI across the solution lifecycle.
• Collaborate with business stakeholders, enterprise architects and cross-functional teams to align AI architecture decisions with business needs and guide solution delivery.
• Other cognate duties

To qualify, candidates must have:

• A related bachelor's degree in Computer Science, Information Technology, or a related field or any STEM degree (Science, Technology, Engineering or Mathematics)
• Proven experience as an AI Architect, designing enterprise-grade AI solutions over the last five years.
• Strong expertise in Generative AI, LLMs, Agentic AI, RAG, Machine Learning, Data Engineering and cloud platforms.
• A proven track record of taking AI initiatives from proof of concept (PoC) to production and scale.
• A strong understanding of the AI/LLM lifecycle, MLOps/LLMOps, observability, security and Responsible AI.
• Experience designing scalable, resilient and secure AI architectures, including APIs, integration and supporting infrastructure.
• The ability to translate business requirements into end-to-end AI architectures and reusable architecture patterns.
• The ability to bridge business strategy, enterprise architecture and technology innovation.

Ideally, you will also have

• Experience defining reusable AI architecture patterns for enterprise-wide adoption.
• Experience assessing AI technology choices and architectural trade-offs against business and operational requirements.
• A deep practical understanding of agent architectures, including ReAct and plan-and-execute patterns, tool calling, MCP (Model Context Protocol), context and memory management, and agent evaluation.
• Experience aligning AI architecture standards with enterprise governance, security and Responsible AI requirements.
• A strong understanding of LLMs, embeddings, fine-tuning versus RAG, and evaluation approaches to inform architectural decisions.
• Knowledge of SQL/NoSQL and vector database architectures, and their role in enterprise AI and data solutions.
• Experience with cloud architecture on AWS, Azure or GCP, including containerisation and orchestration using Docker and Kubernetes.

Good to Have

• Multi-agent orchestration and inter-agent communication patterns (A2A, agent swarms)
• Exposure to architecture patterns for model deployment and fine-tuning open-source models, including LoRA/QLoRA.
• Understanding of AI security concerns (prompt injection, data leakage, agent guardrails)
• Contributions to reusable AI architecture patterns or open-source AI/agent architecture initiatives.

What We Offer

• Opportunity to shape enterprise-grade AI architectures and guide AI initiatives from concept to production and scale.
• An AI-native culture where modern technology and architecture-led innovation are embraced.

What we look for

We are looking for an AI Architect who can connect business strategy with enterprise architecture and technology innovation. You will bring a consultative approach to understanding client needs, communicating architectural decisions and guiding cross-functional teams. The ability to challenge the status quo, build stakeholder relationships and define reusable architecture patterns will help you shape AI solutions that can move from proof of concept to production and scale.

If you have a genuine passion for helping businesses achieve their full potential, this role is for you.

If you have the confidence to speak up and influence a team that affects big businesses worldwide, this role is for you.
