  • Familiarity with Azure OpenAI Services, LangChain, Semantic Kernel, or similar frameworks
  • Experience with containerization and orchestration (Docker, Kubernetes)
  • Exposure to NoSQL databases such as Cosmos DB
  • Understanding of secure coding practices and regulated data environments

Required Experience:
  • 7+ years of professional software development experience
  • At least 3 years operating in a Senior or Lead Engineer capacity
