Senior Manager, Microsoft Agentic AI Technical Lead The opportunity We are looking for an experienced Microsoft Agentic AI Technical Lead at Senior Manager level to lead the design, engineering and delivery of enterprise-grade generative AI and agentic AI solutions for our clients. This is a hands-on technical leadership role combining deep AI engineering expertise with solution architecture, client consulting and delivery leadership. You will translate complex business problems into secure, scalable and production-ready solutions, leading multidisciplinary teams from initial discovery and prototyping through to deployment and operation. The role has a strong Microsoft focus, using technologies such as Azure AI Foundry, Azure OpenAI, Microsoft Agent Framework, Semantic Kernel and Copilot Studio . You will apply these technologies pragmatically, determining where agentic AI offers real value and where conventional applications, deterministic automation or human intervention provide a better solution. You will be equally comfortable developing or reviewing working code, whiteboarding architectures with senior stakeholders, leading engineering teams and taking accountability for production outcomes. Your key responsibilities Agentic AI architecture and engineering Lead the end-to-end technical design of enterprise generative AI and agentic AI solutions using Microsoft technologies. Translate business processes, user needs and control requirements into solution architectures, agent specifications, integration designs and engineering backlogs. Design single-agent and multi-agent solutions, selecting appropriate models, tools, orchestration patterns, grounding approaches, memory and human approval points. Make pragmatic platform decisions across Azure AI Foundry, Microsoft Agent Framework, Semantic Kernel, Copilot Studio, Azure OpenAI and custom Azure services. Design secure integrations between agents, enterprise applications, data platforms, knowledge sources and business workflows using APIs, events, messaging and appropriate tool protocols. Establish reusable reference architectures, engineering patterns and accelerators. Recognise when an agentic approach is not justified and recommend simpler, safer or more cost-effective alternatives. Hands-on technical leadership Lead the development of proofs of concept, minimum viable products, reusable accelerators and production AI components. Remain sufficiently hands-on to prototype critical components, review code and resolve complex technical issues. Guide the development of Python-based AI applications, APIs, microservices and cloud-native integrations. Define engineering standards covering source control, automated testing, CI/CD, infrastructure as code, secrets management and release management. Provide technical direction across orchestration, tool calling, retrieval-augmented generation, structured outputs, context management and asynchronous workflows. Ensure solutions are modular, testable and supportable rather than dependent on fragile prompts or opaque behaviour.
