AI Engineer

Job Purpose
Design and deliver robust AI solutions for defined use cases, addressing complex (non-trivial) modeling, evaluation, and production challenges within project scope.
Apply and extend existing patterns, tools, and frameworks to improve AI system quality, performance, and efficiency within the team.
Ensure reliable end-to-end AI lifecycle execution (data, model, deployment) in production environments, following established standards and practices.
Act as a strong technical contributor, resolving complex issues within scope, supporting team delivery, and operating effectively under real-world constraints with moderate guidance.
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.
