Job summary

IntelliBee Inc. seeks a Senior .NET Developer in Mechanicsburg, PA to lead AI-enabled software projects using Blazor, ASP.NET Core Web API, and Azure services.

You will review AI outputs, design robust data models in Cosmos DB, and secure APIs with Okta while collaborating with product, security, and architecture teams. The role requires 8+ years of software experience, a proven senior-contributor track record, and hands-on work with AI agents.

Qualifications

• 8+ years of professional software development experience, with at least 5 years in C# / .NET at a senior level.
• Proven track record of delivering independently as a senior contributor or technical lead, ideally on prior contract engagements.
• Proficient with Microsoft Blazor (Server and/or WebAssembly): component design, state management, and performance.
• REST API design and development (ASP.NET Core Web API), including versioning, error handling, and OpenAPI/Swagger.
• Azure Cosmos DB (NoSQL): data modeling, partition keys, RU optimization, indexing, and change feed.
• Okta integration: SSO, OIDC/OAuth 2.0, token handling, and role- or claim-based authorization.
• Hands-on experience using AI coding assistants and agents (Claude, Cursor, or similar) in real production workflows.
• Strong code review skills, with the ability to spot subtle bugs, security flaws, hallucinated APIs, and over-engineered code.
• Solid knowledge of security best practices (OWASP, secrets management, input validation).
• Prompt engineering and agent workflow design (rules files, context management, tool use).
• Experience with the Claude API or Model Context Protocol (MCP).
• CI/CD with Azure DevOps or GitHub Actions, and automated testing (xUnit, bUnit, integration tests).
• Azure services such as App Service, Key Vault, and Application Insights.
• Experience building internal developer tools or platforms.
• Bonus: Claude Certifications (Nice to Have, Not Required)

Responsibilities

• Review and validate AI-generated code and other output (Claude, Cursor) for correctness, security, performance, and maintainability.
• Decide how to handle each AI output: approve as-is, refactor, discard, or escape for human or specialist review.
• Define and refine review criteria, guardrails, and quality checks for agent-generated output.
• Design and optimize Cosmos DB data models, partitioning strategies, and queries.
• Build and secure REST APIs, integrating authentication and authorization through Okta (OIDC/OAuth 2.0).
• Write effective prompts and agent instructions and give feedback to improve output quality.
• Document decisions, patterns, and review criteria so the knowledge stays with the team after the engagement ends.
• Collaborate with product owners, architects, and security teams.
• Design, build, and maintain features using Blazor, .NET, and REST APIs.
