• Design and orchestrate AI solutions using services such as Azure OpenAI, Azure AI Services, and agent frameworks (e.g., Semantic Kernel, Microsoft Agent Framework / AutoGen, or the OpenAI/Anthropic SDKs).
• Implement retrieval-augmented generation (RAG), advanced prompt engineering, tool/function calling, and vector-based search to ground AI on enterprise content.
• Establish engineering standards, conduct code reviews, and mentor junior and mid-level developers.
• Partner with stakeholders and architects to translate business requirements into technical designs and delivery roadmaps.
• Integrate AI capabilities responsibly, incorporating security, privacy, evaluation, and governance considerations throughout.

Compensation: -The anticipated base salary range offered for this role will be between $140,000 to $175,000 and represents the firm’s good faith and reasonable estimate of the range of possible base compensation.

• Proficiency developing in Visual Studio(and/or VS Code).
• Mastery of all phases of the software development life cycle (SDLC)— architecture, design, implementation, testing, deployment, and documentation — and the ability to embed security considerations into every phase.
• Strong experience with Web Services, RESTful APIs, and SOAP APIsto integrate applications with vendor and enterprise systems.
• Demonstrated technical leadership — mentoring developers, owning architectural decisions, and driving best practices across a team.
• Excellent problem-solving abilities and an aptitude for rapidly learning and evaluating emerging technologies, especially in the fast-moving AI space.
• Effective interpersonal and written/verbal communication skills, with the ability to communicate technical concepts to both technical and non-technical audiences, and close attention to detail.

Preferred

• Experience delivering AI/agentic solutions for real business processes (document analysis, summarization, intelligent automation, copilots) at production scale.
• Experience working with legal, financial, and HR systems, applications, and databases.
• Experience with client-side technologies such as HTML5, JavaScript, and CSS.
• Experience with client-side development using JavaScript/TypeScript and modern frameworks such as React, plus HTML5 and CSS.
• Experience with legal desktop applications including document management systems, legal workflows, onboarding workflows.
• Working knowledge of Responsible AIpractices — evaluation, guardrails, content safety, and cost/performance optimization of AI workloads.

Experience / Education

• Bachelors degree in Computer Science or a related field.
• Minimum of four yearsof professional software development experience, including hands-on delivery with C#/.NET; demonstrated experience building AI/LLM-based solutions strongly preferred.
