AI Evaluation Engineer/AI Assurance Engineer

4 Months | £750 per day (Inside IR35)

Location: London, Bristol or Manchester (2 days per week onsite)

Security Clearance: Active SC Clearance preferred/eligible and willing to undergo SC Clearance.

Alternative backgrounds may include SDET, AI Evaluation Engineer, AI Assurance Engineer, Prompt Engineer, Harness Engineer or AI Quality Engineer.

This is a hands-on engineering role for someone with deep expertise in AI/ML evaluation, testing and quality assurance, rather than a cloud, infrastructure or platform engineer. You will play a key role in establishing robust evaluation frameworks for production-grade AI systems, helping assure the quality, safety and effectiveness of data-driven and AI-enabled products.

Responsibilities

• Design, develop and deploy AI evaluation and risk management tooling.
• Build and maintain evaluation frameworks for AI, ML and LLM-based products.
• Create and develop code solutions, harnesses and testing capabilities from the ground up using Python.
• Define and execute evaluation strategies across model, agentic and application layers.
• Assess AI system quality, performance, reliability, safety and risk.
• Work closely with technical and non-technical stakeholders across multiple departments and organisations.
• Provide technical leadership and guidance on AI evaluation best practice.

Skills Experience

• Strong commercial experience working with AI, Machine Learning and LLM-based systems in production environments.
• Deep understanding of AI evaluation methodologies, frameworks and quality engineering principles.
• Hands-on Python development experience with the ability to create and maintain your own codebase.

Experience evaluating AI solutions across:

• Model layer
• Agentic layer
• Application layer

Knowledge of AI evaluation tooling and frameworks such as:

• RAGAS
• DeepEval (DP-Eval)
• Other AI evaluation and testing frameworks
• Experience developing automated testing, evaluation harnesses and assurance processes for AI systems.
• Proven leadership experience, including working across teams, departments and organisational boundaries.
• Strong stakeholder engagement and communication skills.
• Public sector or government programme experience. (Desirable)
• Understanding of responsible AI and AI assurance frameworks. (Desirable)

Please Note

This opportunity is specifically seeking candidates with strong AI evaluation and engineering expertise. Experience primarily focused on cloud, infrastructure, platform or DevOps engineering without significant AI evaluation experience are unlikely to be suitable.

Deadline: Friday 21st August.
