Senior Microsoft Power Platform and AI Developer

This role will be mainly remote but require flexibility to travel to client sites, and our offices based in London, Sheffield, and Bristol.

About the role

As a Senior Microsoft Power Platform and AI Developer, you will work with users, product teams, engineers, architects, securityand 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,integrationand 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-offsand safe failure paths. You will ensure that evaluation, observability, identity,permissionsand data boundaries are built into delivery rather than added later.

You will review code and designs, mentor developers, improve engineeringpracticesand 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,deploymentand support of solutions using Power Apps, Power Automate, Dataverse, Copilot Studio andappropriate pro-code extensions.
• Engineer AI agents and agentic workflows using trusted knowledge, tools, actions, approvals, human hand-offs,evaluationand 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,APIsand event-based patterns.
• Apply grounding, retrieval-augmented generation, structured outputs, tool calling and model-selection patterns withappropriate evaluationand operational controls.
• Create custom connectors,plug-insand Azure-hosted components where low-code capability is insufficient, choosing technologies based on need,riskand supportability.
• Set and apply engineering standards for source control, solution packaging, environment strategy, automated testing, CI/CD,monitoringand release management.
• Lead technical investigation of complex live-service faults and improve resilience, performance, accessibility,securityand observability.
• Review designs and code, mentor developers and contribute reusable components,patternsand learning to the wider engineering community.
• Substantial hands-on experience designing,buildingand releasing production solutions with Power Apps, Power Automate, Dataverse and Copilot Studio.
• Experience leading development of AI agents or agentic workflows that use knowledge,toolsand actions to complete meaningful tasks safely.
• Experience integrating or developing MCP servers and tools, or equivalent tool-based agent integration patterns, including troubleshooting identity,permissionsand data flow.
• Strong API and integration skills, including REST/JSON, custom connectors, OAuth 2.0, Microsoft EntraIDand securesecretsmanagement.
• Pro-code engineering capability in one or more languages such as TypeScript/JavaScript,C#or Python, with experience extending low-code services appropriately.
• Strong software engineering practice, including testing, version control, code review, documentation, CI/CD, observability and supporting live services.
• Ability to lead technical decisions for medium-to-high complexity work, communicate trade-offs and elevate architecture or security risks appropriately.
• Practical understanding of security, data protection, accessibility and responsible AI controls for enterprise applications and agents.

Desirable criteria

• Experience with Azure Functions, Logic Apps, API Management, Key Vault, Application Insights, Azure AIservicesor comparable cloud components.
• Experience with retrieval-augmented generation, vector search, embeddings, enterprisesearchand evaluation of grounded responses.
• Experience with agent observability, tracing, prompt and version management, red teaming or automated quality and safety testing.
• Experience integrating Microsoft Graph, SharePoint, Power BI,Fabricor other Microsoft enterprise services.
• Experience defining Power Platform environment, solution, data-loss-preventionand application lifecycle management patterns.
• Relevant Microsoft certifications, or experience delivering technology in government, justice, regulated or security-conscious environments.
