Job description

Play a central role in evolving the architecture toward modern, service-oriented, and intelligent applications built on Microsoft Azure and powered by emerging AI capabilities across the major cloud and AI platforms.

Why Join the company

We’re an AI-first global tech company with 25+ years of engineering leadership, 2,000+ team members, and 500+ active projects powering Fortune 500 clients, including HBO, Microsoft, Google, and Starbucks.

From AI platforms to digital transformation, we partner with enterprise leaders to build what’s next.

What powers it all? Our people are ambitious, collaborative, and constantly evolving.

About the Client

The leading provider of vehicle lifecycle solutions, with headquarters in Chicago, enables the companies that build, insure, and replace vehicles to power the next generation of transportation. Its platform delivers advanced mobile, artificial intelligence, and car technologies. It connects a network of 350+ insurance companies, 24,000+ repair facilities, hundreds of parts suppliers, and dozens of third-party data and service providers. The customer's collective solutions enhance productivity and help clients deliver better experiences for end consumers.

What You’ll Do

• Design and evolve cloud-native architectures across the full platform stack — compute, API management, messaging, eventing, and data primarily on Microsoft Azure (e.g., App Services, Container Apps, API Management, Service Bus, Event Hubs, Azure SQL); equivalent AWS services welcome, Azure preferred
• Define and deliver predictable, resource-oriented REST APIs with a strong focus on performance, security, and developer usability
• Apply microservice and domain-driven design (DDD) approaches to break large business domains into well-bounded services
• Apply modern architectural patterns (e.g., event-driven, CQRS, serverless) for scalable and maintainable solutions
• Produce and present architecture artifacts (sequence diagrams, domain models, data flow diagrams, AI workflows, and cloud blueprints) for both engineering and executive audiences
• Provide technical leadership on cloud modernization, legacy-to-microservices migration, AI-readiness, and platform performance
• Embed security and compliance practices across designs, including identity management, access control, and encryption
• Work with product and data teams to integrate AI and Generative AI capabilities (e.g., Azure AI Foundry, AWS Bedrock / AgentCore, or comparable platforms) into core products and help drive AI-powered automation across the platform
• Champion the use of AI and intelligent automation to lift engineering productivity, code quality, and delivery velocity

What You’ll Bring

• Extensive professional experience in .NET application architecture and development, with a strong C# foundation
• Proven experience designing and deploying cloud-native solutions (Azure or AWS) using microservices, RESTful APIs, and distributed-system design
• Hands-on experience with AI-assisted development tooling (e.g., GitHub Copilot, Claude Code, Cursor, or comparable agentic coding tools) and proven ability to apply them to lift team-wide engineering productivity
• Proven experience with security protocols (OAuth2, OpenID Connect) and identity providers (Okta, Azure AD / Entra ID)
• Working knowledge of application security best practices — secure APIs, rate limiting, secrets management, RBAC, and Managed Identities
• Demonstrated ability to produce and present architecture artifacts (diagrams, specifications, solution blueprints)
• Solid understanding of data integration patterns and event-driven systems, primarily on Microsoft Azure (e.g., Event Hubs, Service Bus, Kafka); equivalent AWS services welcome, Azure preferred
