• Participate in code reviews, contribute to technical standards, and help improve engineering practices across teams
• Collaborate with product owners and TPMs on sprint planning, backlog refinement, and delivery commitments
• Write unit, integration, and end-to-end tests as a normal part of delivery
• Support CI/CD pipeline setup and maintenance using Azure DevOps

Requirements

• US Citizen or Green Card holder (required)
• 5–7+ years of full stack development experience in a US-based environment (required)
• Strong C# and .NET experience delivering and supporting production applications (.NET 6+ preferred)
• Front-end proficiency with React, Angular, or Blazor, including building modern, maintainable UI components
• Hands-on experience building and consuming REST APIs; strong understanding of JSON and OAuth-based security
• Solid SQL skills, including schema design and query optimization; experience with Azure data services (Azure SQL and/or Cosmos DB)
• Working knowledge of Azure cloud infrastructure and common deployment patterns for web apps and services
• Experience working in Agile environments and using Azure DevOps for boards, backlogs, and sprint execution
• Strong problem-solving skills and clear written communication, especially in client-facing contexts

Preferred Qualifications

• Experience with containerization and orchestration (Docker and Kubernetes on Azure)
• Azure Developer or Azure Solutions Architect certification
• Exposure to healthcare, financial services, or other regulated industries
• Familiarity with GraphQL and/or gRPC
• What Success Looks Like
• You deliver production-grade features end-to-end, from data model to API to UI, with strong quality and maintainability
• APIs and services are secure, observable, and reliable, with clear contracts and well-tested behavior
• Azure resources are implemented using sound patterns (secrets in Key Vault, messaging via Service Bus, scalable hosting on App Services/Functions)
• CI/CD pipelines support consistent releases with automated testing and predictable deployments
• Stakeholders have clarity on progress, tradeoffs, and next steps through strong collaboration in Agile ceremonies
• You raise the bar on code quality and standards through reviews, documentation, and pragmatic technical leadership
