Senior AI Engineer (AI Platform)

Salary: £61,000 - 101,000 per year

Requirements:

• Significant experience as an AI Engineer, AI Platform Engineer or in a similar role delivering production-grade AI systems
• Hands-on experience with LLMs, Generative AI and agent-based systems in real-world environments
• Strong understanding of the end-to-end AI lifecycle, from experimentation through deployment and operation
• Practical understanding of production LLM or GenAI runtime concerns such as model access, routing, caching, token usage, cost optimisation and reliability
• High proficiency in Python, with experience building APIs and service-oriented systems
• Experience working with CI/CD pipelines, automated testing and versioned deployments for AI or platform components
• Practical experience with observability tooling, including logging, metrics, tracing and alerting, and using telemetry to improve reliability and performance
• Comfortable working in cloud environments, preferably Azure
• Experience with Azure AI Foundry is preferred, but we are also open to comparable GenAI or agent platforms and applying those patterns within Azure
• Experience with Azure API Management (APIM) is preferred, especially as a governance or integration boundary
• Familiarity with AgentOps, MLOps or GenAIOps concepts, including monitoring, evaluation and feedback loops
• Strong collaboration skills, with the ability to influence platform standards and enable other engineering teams
• A pragmatic, engineering-led approach to responsible and ethical AI, with a focus on safety, reliability and trust

Responsibilities:

• Design and build AI platform capabilities on Azure, with a strong focus on agentic AI patterns such as agent runtimes, orchestration and tool integration
• Contribute to the Agentic AI Platform initiative, helping define how agents are built, integrated and operated across the organisation
• Design and maintain standardised templates and reference implementations for LLM and Generative AI workflows, enabling teams to adopt consistent patterns for prompt design, tool calling, multi-step agent flows, retries and failure handling
• Implement secure, governed access patterns for LLMs and enterprise tools using APIM, platform gateways, Entra ID, RBAC and managed identities
• Contribute to LLMOps and model runtime patterns, including standard approaches for model access, routing, caching, token optimisation and cost-aware usage controls
• Support lifecycle and evaluation practices for agent configurations, prompts and AI workflows, including testing, controlled change and release readiness
• Design secure tool-access patterns for agents, including MCP/tool abstraction, credential management and enterprise API integration
• Contribute to AgentOps and GenAIOps capabilities, including telemetry, run history, task outcomes, error analysis and feedback loops
• Contribute to reliability patterns for production AI systems, including latency monitoring, alerting, scaling considerations and operational readiness
• Apply CI/CD and software engineering best practices to AI platform and agentic components
• Embed observability by default, ensuring AI systems are measurable, debuggable and auditable through logs, metrics and traces
• Partner with Cloud Infrastructure and Security teams to design secure, scalable and cost-effective Azure environments
