• Translate business and product requirements into target architectures and implementation decisions.
• Design agent, RAG, model-routing, integration, API, identity and human-in-the-loop patterns.
• Define hybrid deployment patterns that account for residency, latency, security, performance and cost constraints.
• Evaluate technology choices and document architecture decisions, trade-offs and non-functional requirements.
• Provide technical assurance throughout delivery and support production-readiness reviews.
• Collaborate with existing governance, Responsible AI, cyber, privacy and sector specialists. What we need from you
• 8+ years in solution, enterprise, cloud or AI architecture.
• Strong knowledge of generative AI, agentic systems, data platforms, integration and distributed applications.

• Strong knowledge of RAG and knowledge architectures, including embedding models, vector and hybrid search, reranking, metadata filtering, semantic layers, knowledge graphs, context management and retrieval evaluation.
• Experience designing model-agnostic and multi-model architectures across managed and self-hosted models, including model routing, gateways, prompt and policy layers, structured outputs, caching and latency or cost trade-offs.
• Practical knowledge of MCP and API-based tool integration, event-driven architecture, identity delegation, secrets management, auditability and zero-trust patterns for agents.
• Experience producing architecture artefacts for hybrid deployment using cloud AI platforms, containers and Kubernetes, private networking, on-premises data sources and locally hosted inference where required. Measures of success
