What You'll Do

  • Build scalable, production-ready applications in C# using .NET / .NET Core and current application frameworks
  • Drive the design and rollout of AI features and AI agents that automate tasks, work with enterprise data, and support user workflows
  • Build and orchestrate AI solutions with tools like Azure OpenAI, Azure AI Services, and agent frameworks such as Semantic Kernel, Microsoft Agent Framework/AutoGen, or the OpenAI/Anthropic SDKs
  • Apply retrieval-augmented generation (RAG), prompt engineering, tool/function calling, and vector search to connect AI to enterprise content
  • Set engineering standards, review code, and coach junior and mid-level developers
  • Work with stakeholders and architects to turn business needs into technical designs and delivery plans
  • Build AI features responsibly, factoring in security, privacy, evaluation, and governance at every step

Experience

  • Strong, proven experience building production applications in C# with .NET / .NET Core
  • Real experience building or integrating AI/LLM solutions, including prompt engineering, function/tool calling, RAG, and working with model APIs like Azure OpenAI, OpenAI, or similar
  • Direct experience building AI agents — ones that plan, call tools, hold context, and carry out multi-step tasks — using Semantic Kernel, Microsoft Agent Framework, AutoGen, or LangChain-style orchestration
  • Solid Azure development background, including App Services, Azure Functions, Logic Apps, Key Vaults, Storage Accounts, and Azure DevOps pipelines
  • Strong Azure SQL and T-SQL skills, including building database objects, stored procedures, user-defined functions, and integrated security; familiarity with vector stores like Azure AI Search or Cosmos DB is a plus

  • Experience developing in Visual Studio and/or VS Code
  • Command of the full software development life cycle — architecture through deployment and documentation — with security built in throughout
  • Experience with Web Services, RESTful APIs, and SOAP APIs for connecting to vendor and enterprise systems
  • A track record of technical leadership — mentoring developers, owning architecture calls, and pushing best practices across a team
  • Strong problem-solving skills and a genuine interest in keeping up with fast-moving AI technology
  • Clear communication skills, written and verbal, with the ability to explain technical ideas to both technical and non-technical audiences, plus strong attention to detail

Preferred

  • Experience shipping AI/agentic solutions for real business use cases — document analysis, summarization, intelligent automation, copilots — at production scale
  • Background working with legal, financial, or HR systems and databases
  • Front-end experience with JavaScript/TypeScript and frameworks like React, along with HTML5 and CSS
  • Experience with legal desktop applications, document management systems, or onboarding workflows
  • Familiarity with Responsible AI practices — evaluation, guardrails, content safety, and cost/performance tuning for AI workloads

Experience & Education

  • Bachelor's degree in Computer Science or a related field
  • At least 4 years of professional software development experience with hands-on C#/.NET work; experience building AI/LLM solutions is strongly preferred
