About The Role
As a Senior Microsoft Power Platform and AI Developer, you will work with users, product teams, engineers, architects, security and operational colleagues to turn complex needs into reliable services. You will take technical ownership of significant components and end-to-end solutions and guide decisions across low-code, pro-code, integration and AI patterns.
A major part of the role is engineering AI agents and agentic workflows. You will design how agents use trusted knowledge, approved tools, Model Context Protocol (MCP) services, approvals, human hand-offs and safe failure paths. You will ensure that evaluation, observability, identity, permissions and data boundaries are built into delivery rather than added later.
You will review code and designs, mentor developers, improve engineering practices and support live services. You should be able to challenge inappropriate use of low-code or AI and select a simpler or more supportable approach where evidence supports it.
Key Responsibilities
- Lead the design, build, test, deployment and support of solutions using Power Apps, Power Automate, Dataverse, Copilot Studio and appropriate pro-code extensions
- Engineer AI agents and agentic workflows using trusted knowledge, tools, actions, approvals, human hand-offs, evaluation and safe failure paths
- Design and implement integrations with approved MCP servers and lead development of MCP tools or services using secure, reusable patterns
- Integrate Power Platform and AI solutions with Microsoft 365, SharePoint, Microsoft Graph, Azure services and enterprise systems using connectors, APIs and event-based patterns
- Apply grounding, retrieval-augmented generation, structured outputs, tool calling and model-selection patterns with appropriate evaluation and operational controls
- Create custom connectors, plug-ins and Azure-hosted components where low-code capability is insufficient, choosing technologies based on need, risk and supportability
- Set and apply engineering standards for source control, solution packaging, environment strategy, automated testing, CI/CD, monitoring and release management
- Lead technical investigation of complex live-service faults and improve resilience, performance, accessibility, security and observability
- Review designs and code, mentor developers and contribute reusable components, patterns and learning to the wider engineering community
