Operating in a remote capacity exclusively for Iowa-based residents, this senior technical role is dedicated to engineering resilient backend architectures, optimizing relational database engines, and building responsive, accessible web interfaces. You will drive digital modernization, ensure strict accessibility compliance, and maintain high-availability production workflows across public health and human services platforms.

Detailed Job Description:

The Senior .NET/SQL Full-Stack Developer provides comprehensive full-lifecycle software engineering, systems integration, and database architecture across enterprise-scale applications. In this role, you will architect, implement, and maintain scalable server-side solutions using C#, .NET, and ASP.NET Core, tightly integrated with high-performance Microsoft SQL Server database environments. Day-to-day duties involve designing complex T-SQL queries, stored procedures, indexed views, and automated SSRS analytical reports, alongside developing secure REST and SOAP web services to facilitate robust middleware communication between legacy and modern platforms.

In this mission-critical development capacity, you will champion automated build and release lifecycles using Azure DevOps, participating in continuous integration, unit testing, and production deployment pipelines. You will take ownership of Tier-3 production support, diagnosing complex system defects, resolving application bottlenecks, and implementing digital accessibility standards (WCAG / Section 508) across all web interfaces. Collaborating closely with cross-functional technical teams, state agency stakeholders, and enterprise architects, you will ensure high reliability, regulatory compliance, and seamless operational continuity across critical government and healthcare IT ecosystems.

Key Responsibilities:

• Architect, develop, test, and maintain enterprise full-stack web applications utilizing C#, .NET, and ASP.NET Core frameworks.
• Design, tune, and optimize complex Microsoft SQL Server databases, relational data models, stored procedures, and T-SQL queries.
• Author, deploy, and maintain operational and analytical enterprise business reports utilizing SQL Server Reporting Services (SSRS).
• Design, implement, secure, and maintain high-performance RESTful APIs and SOAP web service endpoints for middleware integrations.
• Build, manage, and optimize automated continuous integration and continuous deployment (CI/CD) pipelines within Azure DevOps.
• Enforce digital accessibility standards (WCAG 2.1 and Section 508 compliance) across all front‑end web user interfaces.
• Provide top‑tier production support, troubleshooting critical application anomalies, integration failures, and database latency issues.
• Conduct comprehensive code reviews, static security analyses, and performance benchmarking across application tiers.
• Spearhead legacy modernization initiatives, refactoring legacy codebase components into scalable cloud‑ready architectures.
• Author and maintain detailed technical architecture documentation, system specifications, API contracts, and operational runbooks.

Required Qualifications & Skills:

• Bachelor’s degree in Computer Science, Software Engineering, Information Technology, or a closely related technical field.
• Minimum of 5+ years of progressive professional full-stack development experience utilizing C#, .NET, and ASP.NET Core.
• Strong practical mastery of Microsoft SQL Server, complex T‑SQL scripting, query performance tuning, and indexing strategies.
• Proven hands‑on experience authoring and maintaining enterprise reports using SQL Server Reporting Services (SSRS).
• Demonstrated proficiency designing, developing, and consuming secure RESTful APIs and SOAP web services.
• Extensive experience building middleware integrations, message handling, and enterprise service connectivity.
• Hands‑on operational experience with Azure DevOps for source code management, work item tracking, and automated CI/CD pipelines.
• Demonstrated background providing production support, system debugging, and rapid incident triage for high‑availability systems.

Nice‑to‑Have Skills:

• Strong hands‑on front‑end development experience with Angular or modern TypeScript web frameworks.
• Practical cloud engineering exposure with Amazon Web Services (AWS) or Microsoft Azure hosting environments.
• Familiarity with distributed version control workflows and repository governance in GitHub.
