Job Description
Build, enhance, and maintainAI-powered product features with a focus oncontinuous product enhancement (CPE) and measurable end-user value. Engineer production-ready AI capabilities (agent tools, prompt optimisation, evaluation and observability) while collaborating closely with data science, AI engineering, and platform stakeholders. Contribute to quality-first delivery throughtesting frameworks, automated checks, and model/feature validation practices. This is a platform engineering and not infrastructure.
Key Responsibilities
- Build and enhance AI-driven features within existing products, prioritising incremental improvements and adoption.
- Develop and maintainagent tools , connectors, and integrations to enable AI workflows.
- Refine and optimiseprompts and interaction patterns for production use cases, including safety and reliability considerations.
- Supportexperiment tracking and model/version management (e.g., MLflow or equivalent).
Testing, Evaluation & Quality
- Build and maintain test functions for AI tools, including exploringagent-based testing patterns (AI validating AI) where suitable.
- Develop evaluation frameworks for AI/agent performance (accuracy, robustness, regressions, hallucination controls as applicable).
- Implementquality gates , automated checks, and release readiness criteria for AI features.
- Supportchampion/challenger validation approaches prior to promotion.
- Contribute tomodel observability and dashboards to track quality, performance, and usage patterns.
- Partner with Data Scientists and AI Engineers to productionise research outcomes into reliable product capabilities.
- Coordinate with Platform/DevOps stakeholders for deployment needs and runtime requirements (without owning infrastructure delivery).
