Lead Technical Architect (AI)

• Architectural Leadership & Integration Design and implement enterprise-grade AI platforms - including semantic search, Retrieval-Augmented Generation (RAG), and broader generative AI/agentic capabilities - integrating cleanly with the department’s complex legacy and multi-cloud environments.
• Responsible AI Governance Embed end-to-end responsible AI controls across the full lifecycle: alignment with the Algorithmic Transparency Recording Standard (ATRS), NCSC "Secure by Design" principles, and active mitigation of algorithmic bias. Ensure every system operates as a decision-support tool that enforces meaningful human control.
• Risk & Value Management Navigate trade-offs between value, risk, pace, and quality using HM Treasury Orange Book and Technology-Organisation-Environment (ToE) frameworks. Identify and resolve systemic risks via Joint Risk Registers.
• Zero-Dependency Handover & Capability Uplift Co-deliver within blended agile teams. Drive knowledge transfer using the OKUA (Ownership, Knowledge, Understanding, Awareness) framework and "Docs-as-Code" practices so internal staff can independently operate and govern AI capability long after the engagement ends.
• Environmental Sustainability (Green AI) Design low-modality, energy-efficient AI architectures aligned with "Circularity Performance Requirements" (Buy Better, Use Better, Use Longer), supporting Net Zero 2030/2040 commitments., * Technical Design Throughout the Life Cycle (Expert): technical designs for high-risk, high-impact, high-complexity systems; leading others toward organisational objectives; refining standards from feedback.
• Architecture Communication (Expert): communicating complex or contentious architecture to technical and non-technical stakeholders at all levels; mediating difficult discussions; securing executive buy-in.
• Making Architectural Decisions (Practitioner): medium-to-high-risk design decisions spanning multiple domains; active contribution to architectural governance and assurance boards.
• Architect for the Whole Context (Practitioner): tracking emerging AI and technology trends; influencing colleagues across the organisation to solve or mitigate problems.
• Strategy Design (Practitioner): defining architectural principles, AI patterns, and strategic vision aligned to wider government objectives; building implementation roadmaps.
• Community Collaboration (Practitioner): proactive networking, resolving team-dynamics issues, using Agile health checks to strengthen the multidisciplinary delivery team.

Alongside The DDaT Competencies, Given The Scale Of This Programme, Hands-on Depth Across The Modern AI Engineering Stack Is Essential, Not Just RAG In Isolation

• Semantic search, vector/embedding infrastructure, and retrieval architecture design
• LLM orchestration and agentic frameworks (e.g. LangChain/LlamaIndex-style tooling, multi-agent patterns)
• LLM evaluation, guardrails, and red-teaming tooling (hallucination detection, safety/bias testing)
• LLMOps / MLOps: model versioning, deployment pipelines, monitoring, and rollback for AI services in production
• Fine-tuning and parameter-efficient adaptation techniques where appropriate to use case
• Data engineering for AI: ingestion, cleaning, and lineage across legacy and multi-cloud sources
• Infrastructure-as-Code and CI/CD practices adapted for AI workloads, with strong observability
• Secure-by-design engineering appropriate to sensitive public-sector data (identity, access control, data protection)

• AWS / Azure / GCP architecture certifications, AI related certifications most desirable.
• Experience contributing to GOV.UK Service Standard alpha or beta assessments
• Prior delivery of AI or digital services within UK central government or wider public sector
• Familiarity with ATRS submissions, HM Treasury Orange Book, or equivalent public-sector risk/assurance frameworks
• Open-source contributions or active engagement in engineering/AI communities
• Experience designing for sustainability/Green IT commitments
