This person will support both client-facing and internal initiatives. The work may include modern web applications, APIs, integrations, data-driven features, and AI-enabled tools such as intelligent search, chat, summarization, workflow automation, and retrieval-based solutions.

We are looking for someone with strong development fundamentals, good problem-solving skills, and the curiosity to keep learning. The right person does not need to be an AI expert, but should have hands‑on exposure to AI tools or a strong interest in applying AI to real business applications.

Design, build, enhance, and support full stack applications for client and internal use.

Build and maintain secure, efficient back‑end services, APIs, and business logic using .NET, C#, TypeScript, Python, and related tools.

Apply object‑oriented programming concepts such as inheritance, polymorphism, encapsulation, and abstraction.

Use basic design patterns and sound coding practices to build maintainable software.

Build and consume REST APIs and integrate third‑party tools, systems, and cloud services.

Contribute to AI‑enabled features such as intelligent search, chat experiences, summarization, workflow automation, and retrieval‑based solutions.

Use AI development tools where appropriate to improve productivity, code quality, and delivery speed.

Work with structured and unstructured data to support application and AI‑related use cases.

Troubleshoot, debug, and resolve application issues across the stack.

Translate business and functional needs into practical technical solutions.

Participate in testing, code reviews, documentation, and production support.

Collaborate with developers, project leaders, business analysts, clients, and other stakeholders.

2 to 5 years of professional software development experience.

Experience building full stack applications in a business environment.

Strong experience with C# and .NET.

Experience with front‑end development using React and/or Angular.

Experience using Python for development, scripting, integrations, data work, or AI‑related use cases.

Solid understanding of object‑oriented programming concepts, including inheritance and polymorphism.

Familiarity with basic software design patterns.

Strong debugging, troubleshooting, and analytical skills.

Experience building and consuming REST APIs.

Working knowledge of SQL and core database concepts.

Exposure to modern AI application development, such as LLM integrations, prompt‑based workflows, semantic search, vector databases, RAG patterns, or similar tools.

Strong communication skills and the ability to work well with both technical and non‑technical stakeholders.

Must be based in the Minneapolis‑St. Paul market.

Experience with Azure or another cloud platform.

Familiarity with AI development tools such as Claude Code, Codex, Cursor, GitHub Copilot, or similar tools.

Familiarity with Azure OpenAI, OpenAI APIs, LangChain, or similar AI development services and frameworks.

Experience with Git, CI/CD, and modern software delivery practices.

Exposure to Docker or container‑based development.

Experience working in a consulting or client‑facing environment.

Understanding of Agile development practices.

The strongest fit will be someone who can write clean, dependable code, ask good questions, and work through technical problems without needing every step defined. This person should be comfortable learning new tools, moving between different types of projects, and communicating clearly with both technical and business teams.

They should also be practical. We are not looking for someone who only wants to experiment with AI. We are looking for someone who wants to build useful software and apply AI where it can improve real business processes.

This is a strong opportunity for a developer who wants to keep growing across the full stack while gaining deeper experience with practical AI applications. You will work on meaningful business problems, support a variety of client and internal needs, and grow within a team‑oriented consulting firm.
