Expert, AI Engineering

Job Purpose

- Lead the design and delivery of advanced AI solutions, ensuring high performance, scalability, and cost efficiency in production environments.

- Solve complex AI challenges (modeling, evaluation, multi-agent systems) and develop reusable frameworks and standards adopted across teams.

- Ensure AI systems are developed and operated responsibly, addressing safety, ethical risks, and governance requirements.

Key Accountabilities (1)

AI Craft - Specialization

- Evaluate novel algorithms and training techniques against production constraints; diagnose and unblock the hardest cross-cutting Modeling problems (severe distribution shift, low-resource settings, multi-task architecture); build reusable Modeling patterns adopted across teams.

- Implement complex multi-agent orchestration, long-running stateful workflows, and quality optimisation at scale; evaluate new models and frameworks hands-on; build reusable agent patterns and prompt libraries adopted across teams.

- Evaluates and adopts advanced optimisation techniques; designs multi-tenant serving and capacity strategies; builds performance-regression frameworks and cost dashboards adopted across teams.

- Recognised expert in the sub-domain inside the org; selects between competing approaches based on production constraints; reviews and unblocks others' sub-domain work; tackles the harder problems (low-resource scenarios, distribution shift, real-time constraints); the person teams escalate to.

AI Craft - Evaluation

- Build evaluation tooling and automated experiment pipelines adopted across teams

- Design and run online A/B tests with statistical rigour & calibrate human and LLM-judge evaluation

- Resolve the hardest evaluation problems (subjective tasks, rare-event detection, long-tail safety).

Key Accountabilities (2)

Engineering for Production

- Design testing strategies for AI systems (data validation, model regression, prompt-output, agent-trajectory tests); evaluate and introduce new tooling; build internal libraries, SDKs, and code templates that raise the engineering floor across teams.

- Architect data platforms that serve both ML training and LLM/RAG workloads; design for cost, latency, and freshness trade-offs; build reusable data-quality, lineage, and observability tooling adopted across teams.

- Architect complex AI systems combining ML and agentic components; design for graceful degradation, cost-efficiency, evolvability, and multi-tenancy; build reference implementations and integration patterns adopted by other teams; lead migration and convergence of inherited or siloed systems where warranted; balance near-term delivery against long-term architectural coherence.

Key Accountabilities (3)

Research & Emerging Technologies & AI Safety, Ethics & Responsible AI

- Conduct in-depth evaluation of emerging AI technologies within the assigned domain/project; build prototypes to validate feasibility and risks; provide recommendations for appropriate implementation approaches for specific use cases.

- Contribute to the development and refinement of responsible AI standards within the domain; ensure solutions comply with established guidelines and regulations.

- Analyse ethical and safety risks of AI systems at solution/project level; propose appropriate risk mitigation measures.

- Participate in designing and executing testing activities (e.g., adversarial testing, risk assessments) to improve system robustness and reliability.

- Support AI risk assessments in product reviews, acting as a technical advisor within the domain.
