• Enforce and extend security best practices, including parameterized queries and TLS 1.2+ enforcement, across legacy and modern services.
• Support FHIR API development and interoperability initiatives aligned with our product roadmap.
• Use GitHub effectively for version control, code reviews, and team collaboration.
• Build and maintain CI/CD pipelines using GitHub Actions to support reliable, continuous delivery.
• Apply AI-assisted development tools (e.g., Cursor, Claude Code, AI copilots) to accelerate analysis, development, and troubleshooting - and help advance our AI development lifecycle across the team.

• 6+ years of experience with Git and GitHub workflows.
• 6+ years of experience debugging and troubleshooting complex, production-grade systems.

• 4+ years of experience navigating unfamiliar, undocumented, or poorly documented codebases.
• 4+ years of experience with SQL Server, including migrations and schema management (experience migrating from MySQL or MariaDB is highly desired).
• 4+ years of experience building, consuming, and supporting RESTful APIs.
• 3+ years of experience with authentication and authorization protocols (OAuth, JWT, etc.).
• 3+ years of experience with Microsoft Azure (compute, networking, storage, Azure SQL, and deployment workflows).
• 3+ years of experience building CI/CD pipelines using GitHub Actions.
• 2+ years of experience working with MySQL or MariaDB databases.
• 2+ years of experience working with Docker for containerized deployments.
• 1+ years of experience using AI coding assistants in daily development workflows.
• Bias for Action - Takes initiative and moves problems forward without waiting to be told.

What would make you stand out:

• Prior experience modernizing or re-platforming legacy systems in a production environment - particularly PHP or VB-based systems.
• Hands-on experience with database migration projects (MySQL / MariaDB SQL Server is a strong asset).
• Experience with Sitecore or similar enterprise CMS/web platforms.
• Familiarity with FHIR APIs or HL7 healthcare interoperability standards.
• Experience working in HIPAA-regulated environments or with healthcare data.

• Exposure to infrastructure-as-code and Azure cloud automation.
• Understanding of system design and data modeling patterns (entity-relationship, object-oriented, layered architectures).
• Familiarity with VB6 or Classic ASP - not required, but a genuine differentiator.
