Lead Ai Engineer (Contract)

About Scrumconnect Consulting

Scrumconnect Consulting is a multi-award-winning digital consultancy, recognised for delivering impactful and innovative technology solutions across UK government departments. Our work has positively influenced the lives of over 40 million UK citizens. We are passionate about user-centred design, agile delivery, and building digital services that make a real difference - and we're now scaling that expertise into large, high-stakes AI adoption programmes across the public sector.

Overview

We're looking for a Lead AI Engineer to be the hands-on technical builder at the core of a large-scale AI Operating Model programme for a central government department. Where the Lead Technical Architect sets direction, you turn it into working, production-grade systems - semantic search, RAG pipelines, and broader generative AI capability - integrated into complex Legacy and multi-cloud environments handling high-volume, sensitive public sector data.

You'll work inside a collaborative "Rainbow Team" alongside civil servants and the wider delivery team, staying close to the code while also mentoring engineers and helping build the internal capability the department needs to eventually run these systems without long-term reliance on external suppliers.

Key Responsibilities

Required Skills & Experience

Loosely mapped to the Government Digital and Data (DDaT) framework, at Lead Engineer level:

- Coding and Scripting (Expert) - writing production-grade, well-tested code; setting standards for others; comfortable owning components end-to-end.

- Systems Design (Practitioner) - designing components that integrate cleanly into a wider, architect-defined system; understanding trade-offs across the stack.

- Data Engineering (Practitioner) - building reliable pipelines to ingest, clean, and prepare data (including unstructured/Legacy sources) for AI consumption.

- DevOps/Continuous Delivery (Practitioner) - CI/CD pipelines, infrastructure-as-code, and automated deployment for AI workloads specifically (not just conventional web services).

- Testing & Evaluation (Practitioner) - beyond conventional unit/integration testing, building evaluation harnesses for AI system quality: retrieval accuracy, hallucination rate, bias/fairness checks.

- Problem Solving (Practitioner) - diagnosing and resolving complex, ambiguous technical issues under production pressure.

- Agile Working (Practitioner) - delivering iteratively within a blended, multidisciplinary team including civil servants.

Given the scale of this programme, direct hands-on depth across the AI engineering stack is essential:

- Strong general-purpose programming (most commonly Python) applied to AI/ML systems

- Semantic search, vector/embedding infrastructure, and RAG pipeline construction

- LLM orchestration and agentic frameworks (eg LangChain/LlamaIndex-style tooling, multi-agent patterns)

- Prompt engineering and systematic evaluation/guardrail tooling (hallucination detection, safety testing)

- LLMOps/MLOps - model versioning, deployment, monitoring, and rollback for AI services in production

- Cloud-native engineering across major providers (AWS, Azure, or GCP), including their AI/ML tooling

- Containerisation and infrastructure-as-code for repeatable, auditable deployments

- Secure-by-design engineering appropriate to sensitive public-sector data

Desirable Experience

- AWS/Azure/GCP certifications (associate or professional level)

- Prior delivery of AI or digital services within UK central government or wider public sector

- Experience fine-tuning or adapting open-source/foundation models for a specific domain

- Open-source contributions or active engagement in AI/ML engineering communities

- Experience designing for sustainability/Green IT commitments

- The technological capabilities can span a wide range of AI and automation tools, including Virtual Assistants, Robotic Process Automation (RPA), Computer Vision, Natural Language Processing (NLP), Machine Learning, Deep Learning, Generative AI, Frontier LLMs, and Predictive AI. A strong candidate would have experience/exposure to nuances of these tools/technologies.

Location and Working Pattern

Hybrid, based from Newcastle upon Tyne, with on-site attendance required for workshops, knowledge-transfer sessions, and onboarding. All production system and data access must be performed solely from within the UK.
