• Support deployment, documentation, and operational handover
• Collaborate with architecture, data engineering, DevOps, and QA
• Build a shared rules library used consistently by publishing and query services
• Implement guarded graph queries that refuse unsupported or prohibited responses (Guided)
• Produce validated JSON-LD and API responses with source and provenance information
• Create regression tests for publication rules, disclaimers, and other safety-critical behavior

Required Qualifications:

• Solid professional experience with C# and .NET development
• Experience building and testing ASP.NET Core APIs
• Experience with JSON and external system integrations
