## About the Role

We need a Senior .NET Backend Engineer Consultant (AI-Forward) to build the APIs at the center of a pharmacy platform. Prescription and claims data pass through the services you'll own. You understand pharmacy workflows well enough to know why a controlled-substance refill, a transfer and a prior-auth denial each need different handling. This is a corp-to-corp, 1099 engagement for an independent consultant who works autonomously and uses AI tools daily to multiply their impact.

Key Requirements

 * 10+ Years of C# / .NET
 * ASP.NET Core Web APIs on current .NET, EF Core and Dapper.
 * Clean, testable service design: idempotency, resilience, observability; unit, integration and end-to-end tests.
 * SQL Server
 * Strong SQL, including working confidently inside large existing schemas.
 * Azure
 * Key Vault, Storage, Application Insights, managed identity, containers.
 * Securing services with Entra ID; CI/CD (GitLab, GitHub or Azure DevOps).
 * Pharmacy Software (Required, 3+ years)
 * Building software for a pharmacy or PBM: prescription lifecycle, NCPDP claims, NDCs and drug data, NPI and DEA, refill and transfer rules, controlled-substance handling.
 * Experience with HIPAA-regulated systems and PHI.
 * AI-Forward Engineering
 * Daily practitioner with AI coding tools and agents: Claude Code, OpenAI Codex CLI, GitHub Copilot or Cursor.
 * Prompt and instruction design: translate business rules into structured prompts, tools and context.
 * Code review and output evaluation with a human in the loop; you own what ships., Experience: C# / .NET, 10+ years (required); pharmacy or PBM software, 3+ years (required)

## Description

* Safety and compliance: PHI redaction, secrets in Key Vault, nothing sensitive in prompts, logs or test data.
 * Consulting & High EQ
 * Confident with engineers, product owners, pharmacists and technicians alike; you turn workflow detail into resilient systems.
 * Owner mindset, clear communication and crisp trade-off framing.
 * Entrepreneurial Mindset
 * Think like an owner; deliver measurable value. We welcome consultants building their own ventures.
 * Business Structure
 * Must have an active LLC or S-Corp; 1099 only (Corp-to-Corp). 2+ years running your own consulting company strongly preferred.

What You'll Do

 * Build APIs: Design and build ASP.NET Core Web APIs on current .NET with EF Core, Dapper and SQL Server.
 * Own Pharmacy Domain Logic: Prescriptions, claims and patient medication records, including controlled-substance rules.
 * Integrate: Connect pharmacy management systems and other healthcare and business partners; work with event streaming and healthcare messaging where needed.
 * Secure & Operate: Entra ID authentication, Azure containers, CI/CD, and the tests that keep releases safe.
 * Use AI Well: Apply AI tools to accelerate design, coding, testing and review while keeping PHI inside controlled boundaries.

Preferred Tech & Tooling

 * .NET 8+, C#, ASP.NET Core, EF Core, Dapper, SQL Server
 * Azure (Key Vault, Storage, Application Insights, container hosting), Entra ID, CI/CD (GitLab, GitHub or Azure DevOps)
 * Kafka or HL7 v2 messaging
 * Agentic IDEs: Claude Code, OpenAI Codex CLI, Copilot/Cursor

Nice to Have

 * Hands-on with a pharmacy management system's data model or integrations.
 * HL7 v2 or Kafka in production.
