Senior AI Software Engineer

Job Description

Senior and Lead Software Engineers (AI Engineering, .NET, Azure)

Chicago, Dallas, Houston or New York (Hybrid)

Full-time, direct hire

Multiple openings at both levels

About the Company

Our client is a top global law firm investing heavily in AI. Its growing engineering team builds new AI-powered applications for lawyers and business teams and works with the latest AI coding tools.

About the Role

These are hands-on roles for engineers who build AI into real products, not just use AI to write code. Most of the work is greenfield .NET and Azure development: AI-powered litigation applications, enterprise workflow automation (billing, invoicing, HR, M&A and pricing), and turning internally built “vibe-coded” apps into enterprise-grade software. The team builds with tools like Claude Code, runs peer design reviews and pair programming, and has a dedicated DevOps group. Leads set technical direction and mentor while still writing production code, with no direct reports. Interviews are conversational and technical, with no live coding.

What You’ll Do

• Build AI into production applications: LLM features, retrieval-augmented generation (RAG), agents and deterministic AI workflows, including on Azure OpenAI Service
• Design and build scalable C#/.NET services and APIs on Azure, with React or Next.js front ends
• Make AI dependable: structured outputs, evals, grounding with citations, human review where it matters, and strict permissions on confidential data
• Harden internally built prototypes into secure, tested, maintainable software
• Work directly with non-technical stakeholders to turn business problems into shipped solutions
• Lead level: guide architecture and AI engineering standards, run code and design reviews, build POCs and mentor engineers

What You Bring

• Senior: 5+ years of professional software development (internships don’t count). Lead: 8+ years preferred, including hands-on technical leadership
• Strong C#/.NET back end: APIs, services, and SQL Server, PostgreSQL or Cosmos DB
• Production Azure, such as App Service, Container Apps or AKS, Azure SQL, Service Bus and Azure OpenAI Service
• AI you’ve built into a real product (LLM features, RAG, agents or AI workflows), and the ability to walk through its architecture, what broke and how you fixed it
• Daily AI-assisted development, ideally with Claude Code (Codex also relevant)
• Full-stack experience with React or Next.js (Angular translates); leaning back end or front end is fine
• Working knowledge of CI/CD and deployments (Azure DevOps or GitHub Actions)
• Clear communication with non-technical stakeholders, and ownership of features from design to production
• Bachelor’s degree in computer science or a related field (equivalent experience considered for Lead)
• US work authorization without sponsorship, now or in the future

Nice to Haves

• Azure AI Search, Semantic Kernel, MCP, or workflow platforms such as n8n or Temporal
• LLM evals and observability, and AI security (prompt injection, least-privilege tools)
• Legal industry experience (helpful, not expected)
