• Understand client objectives and translate them into practical technology solutions that deliver measurable business outcomes.

• Design, develop, and deploy solutions using the appropriate combination of software engineering, Azure services, Azure OpenAI and Microsoft Foundry, Copilot and agent frameworks, GitHub, automation tooling, platform engineering, data technologies, and integration patterns.

• Develop reusable assets and implementation patterns that can be applied across teams and engagements.

• Support solution adoption and enable client teams through knowledge sharing and collaborative delivery.

• Partner directly with client stakeholders, engineers, architects, operators, and business leaders to ensure solutions are aligned with organizational goals and operational realities.

• Experience with Model Context Protocol (MCP) and agent-to-agent interoperability patterns, and with evaluating, monitoring, and governing AI solutions in production.

• Ability to rapidly understand business processes, technical environments, and organizational challenges.

• Experience applying modern engineering practices, including AI-assisted development with GitHub Copilot, to improve delivery quality and productivity.

• Strong client engagement and communication skills, with the ability to explain complex topics to technical and non-technical stakeholders.

• This role requires 6-10 years of experience as an Architect Cloud Consultant.

Great If You Also Have

• Experience building and deploying production systems on Azure, including APIs, GitHub Actions or Azure DevOps pipelines, and infrastructure-as-code (Bicep or Terraform).

• Building with Azure OpenAI Service, Microsoft Foundry, Microsoft Agent Framework, or Copilot Studio.

• Experience with Microsoft Fabric or Azure data services as grounding sources for AI solutions.
