• Develop secure, high-performance backend services using .NET Core and ASP.NET Web API, applying strong object-oriented design, clean architecture principles, and proven enterprise patterns.

• Design and implement scalable architecture patterns - including microservices, service-oriented designs, and event-driven workflows - that support the demands of growing, distributed user bases.

• Build modern, responsive front-end applications using Angular, React, or similar frameworks, ensuring excellent user experience, accessibility, and performance across browsers and devices.

• Develop and optimize relational database schemas, stored procedures, indexes, and complex queries in SQL Server, with attention to performance, locking behavior, and long-term maintainability.

• Produce thorough architecture and technical design documentation, ensuring alignment with performance, security, compliance, and operational standards of the enterprise.

• Participate in system design discussions and ensure that development consistently aligns with enterprise architecture constraints, technology road-maps, and platform standards.

• Implement robust authentication and authorization mechanisms using OAuth2, OpenID Connect, JWT, and modern identity management services such as Azure AD or Okta.

• Contribute to CI/CD pipeline integration, automated builds, infrastructure-as-code practices, and reliable deployment processes across development, staging, and production environments.

• Perform thorough root-cause analysis and methodically troubleshoot production issues, working to restore service quickly while ensuring long-term operational stability.

• Identify technical debt, performance bottlenecks, and architectural gaps, and proactively propose and implement well-scoped improvements with measurable benefits.

• Collaborate fully in Agile/Scrum environments - including planning, daily standups, demos, and retrospectives - to deliver incremental, high-quality releases on a predictable cadence.

• Maintain comprehensive documentation of systems, APIs, integration workflows, and operational runbooks so that the team can scale and onboard new engineers efficiently., Senior .NET Developer (C#) , Phoenix, AZ (Hybrid) Location: Phoenix, AZ 85007 , Hybrid (local Phoenix only) Type: Contract (18 months)
