Senior AI Application Engineer (.NET

We're looking for a Senior AI Application Engineer (.NET) to design, build, and scale intelligent enterprise applications powered by modern AI technologies. This role is ideal for an experienced C#/.NET software engineer who has applied technologies such as LLMs, Retrieval-Augmented Generation (RAG), vector search, and AI agents to solve real-world business challenges. You'll develop secure, scalable, production-ready solutions that enhance search experiences, automate complex workflows, and unlock knowledge across enterprise systems.

Rather than building foundational AI models, you'll focus on integrating and operationalizing AI within enterprise-grade applications, transforming emerging technologies into impactful solutions that deliver measurable business value.

• Design, build, and maintain AI-powered enterprise applications using C#, .NET, cloud-native technologies, and LLMs.
• Develop and optimize RAG-based solutions using enterprise data, embeddings, and vector search to enable relevant, context-aware experiences.
• Integrate AI capabilities through AWS Bedrock or similar platforms, including prompt engineering, guardrails, and safety controls that improve quality and reliability.
• Build conversational and agentic experiences that coordinate tools, functions, and multi-step reasoning, including MCP tools, functions, and server integrations.
• Partner with product, architecture, and engineering teams to deliver scalable, maintainable AI systems and establish strong evaluation, observability, and monitoring practices.

• Bachelor’s degree in Computer Science, Engineering, Artificial Intelligence, or a related field, or equivalent practical experience.
• Strong programming and system design skills in .NET or Java with experience building APIs and cloud-native backend services.
• 5+ years of professional software engineering experience developing enterprise applications using C# and .NET.
• Strong hands‑on experience with RAG architectures, embeddings, vector databases, semantic search, and cloud AI platforms such as AWS Bedrock or equivalent.
• Experience designing agentic workflows, integrating MCP tools and servers, and building AI experiences for chat or conversational user interfaces.

• Have a strong background building enterprise applications with C# and .NET.
• Have recently incorporated AI capabilities into existing products, platforms, or workflows.
• Are comfortable moving between architecture, hands‑on development, integration, and production support.
• Enjoy solving practical business problems with technology rather than building experimental proofs of concept.
• Can balance software engineering best practices with the rapid pace of emerging AI technologies.
