About The Position

Cobalt Benefits Group (CBG), a healthcare third-party administrator, is seeking an AI Developer to design, build, test, and deploy governed AI solutions that improve operational efficiency and member experience. This hands-on role turns approved use cases into production-ready retrieval-augmented assistants, document-extraction agents, and AI-enabled workflows using custom development and low-code Microsoft tools. The developer partners with business owners, DevOps, IT Security, Compliance, and AI governance stakeholders to integrate solutions securely with core systems and establish reusable patterns for responsible AI delivery. Solutions must meet CBG governance and technical security requirements, with privacy, security, and human oversight proportionate to risk. Automated claim denials without human review and the use of PHI in public generative AI models are prohibited. Work aligns with HIPAA, HITRUST CSF, the NIST AI Risk Management Framework, and applicable OWASP guidance. Technology varies by project and risk tier and includes Microsoft 365 Copilot, Copilot Studio, Power Automate, Power Apps, Teams, Azure OpenAI / Azure AI Foundry, Azure AI Search, Azure API Management, Entra ID, Key Vault, Azure SQL, Cosmos DB, Azure Data Lake Storage, Blob Storage, Dataverse, GitHub, and CI/CD pipelines. Success measures include completing AI governance onboarding, shipping an enhancement through Production Readiness Review, and establishing a golden-test-set evaluation harness in the first 90 days; releasing a new approved AI solution, publishing reusable components adopted by another project, and enabling monitoring dashboards within six months; and meeting approved business KPIs, demonstrating reusable delivery patterns, and maintaining current inventory, risk classification, evaluation, and monitoring records within 12 months.
