About the Job

Requirements

  • 7+ years of solution or cloud architecture experience, with strong command of cloud concepts; Azure is strongly preferred, while equivalent GCP or AWS experience is considered.
  • Hands-on experience with Azure AI Foundry and core Azure AI services.
  • Demonstrated experience designing cloud-native, enterprise-scale solutions and strong grasp of Well-Architected Framework principles: reliability, security, cost optimization, and operational excellence.
  • Hands-on architecture experience with Microsoft Copilot Studio, including designing agents, topics, tools, and orchestration for enterprise scenarios.
  • Working knowledge of Azure AI Foundry agent service, model catalogue, and evaluations, and Model Context Protocol as an integration pattern.
  • Understanding of retrieval-augmented generation and knowledge-grounding design, including chunking and retrieval strategy, Azure AI Search or vector stores, grounding evaluation, and choosing between retrieval-augmented generation, fine-tuning, and tool use.
  • Experience taking AI or agent solutions from prototype into production, including evaluation, security, observability, and release gating.
  • Familiarity with enterprise agent platforms such as Moveworks or Lyzr and ability to assess fit-for-purpose and build-versus-buy decisions.
  • Working knowledge of Python or C# at code-review depth, including reading, reviewing, and critiquing production code, challenging technical designs, and guiding pro-code engineers.
  • Working knowledge of REST APIs and SDKs, and authentication and authorization patterns including OAuth 2.0, OpenID Connect, Entra ID app registrations, managed identity, and on-behalf-of flows.
  • Understanding of modern engineering practices including version control, code review, continuous integration and continuous delivery, and infrastructure as code, sufficient to set standards and hold delivery teams to them.
  • Architecture-level knowledge of Microsoft Power Platform, including Power Apps, Power Automate, Copilot Studio, and AI Builder.
  • Experience designing scalable, governed Power Platform solutions with sound application lifecycle management across environments.
  • Familiarity with the Microsoft 365 ecosystem, including SharePoint, Teams, and Dataverse, and identity and security including Entra ID, OAuth 2.0, and managed identity as they relate to AI solution design and integration.
  • Ability to communicate complex technical concepts to non-technical senior stakeholders.
  • Comfort with AI-assisted rapid prototyping to validate concepts quickly and unblock the team.
  • Collaborative approach and experience guiding and mentoring delivery teams, including vendor and partner engineers.

Responsibilities

  • Partner with the IT Director and internal client teams to translate complex business requirements into scalable, enterprise-grade AI architectures, primarily using Azure AI Foundry, Copilot Studio, and Power Platform, with enterprise agent platforms where appropriate.
  • Own end-to-end solution design across pro-code and low-code delivery, from client discovery and MVP scoping through architecture governance, integration design, production hardening, and team enablement.
  • Work directly with internal clients to understand use cases, identify core problems and success criteria, and translate requirements into a clearly scoped MVP; act as the technical voice in stakeholder conversations.
  • Design and own end-to-end architectures for AI solutions using Azure AI Foundry, Copilot Studio, and Power Platform, complemented by suitable enterprise agent platforms; produce high-level and low-level designs and architecture decision records to guide delivery teams.
  • Lead the design of AI agents and agentic workflows using Copilot Studio and Azure AI Foundry, including Model Context Protocol-based integration, knowledge grounding, tool orchestration across connectors and enterprise data, and evaluation approaches.
  • Design how agents access and ground on enterprise data across Dataverse, SharePoint, Microsoft Fabric/OneLake, SQL, Azure AI Search, or vector stores; own chunking, retrieval, and indexing strategy, and determine when retrieval-augmented generation, fine-tuning, or tool use is appropriate.
  • Own the path from prototype to production, including evaluation frameworks, golden datasets, offline and online evaluation, regression testing of agent behavior, release gating, tracing, and security hardening against prompt injection, over-permissioned tools and Model Context Protocol servers, data exfiltration, and unsafe content; conduct red-teaming before go-live.
  • Assess existing automations and AI assets and define a roadmap to evolve them onto the platform stack in a production-grade, governed, maintainable way aligned with enterprise standards.
  • Design integration of AI capabilities with enterprise systems and data using connectors, Model Context Protocol, and APIs; ensure integration with Microsoft 365, ServiceNow, ERP, HR platforms, and other enterprise sources.
  • Embed monitoring, tracing, and evaluation into every architecture using Azure AI Foundry evaluation and tracing, Copilot Studio analytics, Azure Monitor/Application Insights, and Power Platform Center of Excellence; ensure solutions are measurable, auditable, and trustworthy at scale.
  • Ensure every solution passes through WTW’s Responsible AI intake and governance processes; design for data classification, privacy, least-privilege access, and auditability, and partner with Security, Privacy, and Risk colleagues to meet regulated-industry obligations.
  • Work with delivery teams as a trusted design partner; review code and designs across pro-code and low-code workstreams, including vendor and partner engineers; set standards for authentication, APIs, continuous integration and continuous delivery, and infrastructure-as-code patterns; establish reusable components and reference architectures; drive application lifecycle management and governance across environments.
  • Guide model selection, token budgeting, and capacity decisions, including provisioned versus pay-as-you-go approaches, and embed cost monitoring to sustain economic viability as solutions scale.
  • Maintain awareness of the AI tooling landscape and evaluate and recommend emerging platforms, frameworks, and patterns that could improve delivery speed, capability, or cost efficiency.

Desired Qualifications

  • Relevant Microsoft certifications, particularly Azure Solutions Architect Expert (AZ-305), Azure AI Engineer Associate (AI-102), and Power Platform Solution Architect Expert (PL-600) or Power Platform Developer Associate (PL-400).
  • Working knowledge of modern front-end frameworks and languages such as React, Angular, or TypeScript.
  • Hands-on continuous integration and continuous delivery experience with Azure DevOps Pipelines or GitHub Actions, and infrastructure-as-code experience with Bicep or Terraform.
  • Experience delivering AI solutions in a regulated industry such as financial services or insurance, with data privacy and audit obligations.
  • Experience working alongside vendor or partner delivery teams in a multi-vendor model.
