Senior .NET Backend Engineer Consultant (AI-Forward) — Pharmacy Platform

Who We Are

Proactive Logic Consulting INC is a boutique technology consulting firm. We build the systems and capacity behind our clients' value creation plans, working with private-equity-backed companies and operators in healthcare, insurance and financial services:

• AI Workflow Automation
• Data & KPI Visibility
• Legacy Workflow & Application Modernization
• Cloud & Data Foundations
• Flex Senior Technology Talent

We bring together top-tier independent consultants—experts in their craft who thrive on flexibility and autonomy. Our consultants have a customer-obsessed mindset, high EQ, and deep technical skills. We're entrepreneurial at heart and fully support consultants who are building their own products on the side.

What We're Looking For

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.
• LLM integration where it earns its place (Azure OpenAI / OpenAI / Anthropic): tool calling, structured outputs, guardrails.
• 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.

How to Apply

Please send

• Your resume or consultant profile highlighting .NET, SQL Server and pharmacy or PBM software work.
• A short note on your LLC or S-Corp (name, state).
• Links to relevant work (APIs, write-ups, demos or repos).
• 3–5 lines on how you use AI tools (Claude Code, Codex CLI, etc.) to accelerate delivery while keeping PHI safe.

Optional (helps us fast-track you)

answer in 1–2 sentences each.

• What has to be true before a pharmacy can fill a faxed Schedule II prescription?
• A claim rejects, then a corrected claim is submitted. How do you design the reversal and retry path so nothing is double-billed?
