The Role

We are looking for experienced Dynamics 365 and Power Platform Developers to join a high-profile public-sector transformation programme.

There are opportunities at both Senior and Lead level, with the level determined by your technical experience, delivery capability and leadership background.

You will work on Dynamics 365 Customer Service solutions, alongside Power Pages, Power Automate and Azure services, delivering robust solutions across a complex enterprise environment.

  • Developing and maintaining Power Pages sites, including Liquid templates, web templates, Table Permissions and authentication.
  • Building Power Automate flows for business process automation and integration, including appropriate error handling and retry behaviour.
  • Developing Azure Functions to extend Dynamics 365 and integrate with external systems.
  • Developing Dynamics 365 Plug-ins, Custom APIs and PCF controls where configuration alone cannot meet requirements.
  • Working with APIs and integration patterns between Dynamics 365, Dataverse and external systems.
  • Taking ownership of features from refinement through development, release and defect resolution.
  • Working with Azure DevOps, source control and deployment pipelines.
  • Applying an "out-of-the-box first" approach and challenging unnecessary customisation.
  • Identifying technical risks and debt and contributing to technical solutions and improvements.
  • Working closely with Business Analysts, Project Managers, Solution Architects and wider technical teams.
  • Communicating technical concepts and decisions clearly to both technical and non-technical stakeholders.


For Lead-Level Candidates

Lead candidates will additionally be expected to:

  • Lead the development workstream and act as a senior technical point of contact.
  • Provide technical direction and break solution designs into practical development tasks.
  • Lead, mentor and support developers across different experience levels.
  • Allocate development work against backlog priorities.
  • Conduct code reviews and maintain development standards.
  • Support defect triage, root-cause analysis and technical decision making.
  • Work closely with the Solution Architect to translate designs into buildable solutions.
  • Take ownership of technical quality, consistency and delivery across the development team.


What We're Looking For

Essential:

  • Strong hands-on experience with Dynamics 365 Customer Service.
  • Strong Power Platform development experience, particularly Power Automate and Power Pages.
  • Strong knowledge of Dataverse and model-driven applications.
  • C# and .NET development experience, including Dynamics 365 Plug-ins and Custom APIs.
  • Practical experience developing and deploying Azure Functions.
  • Experience with Dynamics 365 / Dataverse integrations and APIs.
  • Experience working with Azure DevOps and source control.
  • Ability to work independently and make sound technical decisions.
  • Strong communication skills and the ability to engage with both technical and business stakeholders.
  • Experience working within an Agile/Scrum delivery environment.
  • Ability to successfully complete BPSS checks prior to commencing the assignment.

For Lead-level positions, we are particularly interested in candidates with:

  • Previous experience leading or mentoring Dynamics 365 development teams.
  • Experience with code reviews and setting development standards.
  • Experience translating architectural designs into development tasks.
  • Strong technical ownership and stakeholder management experience.


Desirable

  • Experience with Azure integration services such as Logic Apps, Service Bus or API Management.
  • Dataverse security design, including business units, column-level security and hierarchy security.
  • Previous public-sector delivery experience.
  • Experience working with GDS web portals and WCAG accessibility requirements.
  • Microsoft certifications such as PL-400, PL-600 or MB-230.


The Opportunity

This is a strong opportunity to join a technically challenging public-sector programme working across the Dynamics 365, Power Platform and Azure ecosystem.
