Integrate AI capabilities such as LLMs, RAG, vector search, embeddings, and agentic workflows into enterprise applications. Write clean, maintainable, production-ready code and contribute to architecture discussions, technical design reviews, and code reviews. Contribute to CI/CD pipelines, infrastructure automation, and cloud deployments to improve development velocity and operational excellence. Collaborate with product, architecture, and engineering teams to deliver scalable solutions that solve complex business challenges. Troubleshoot and resolve issues across development and production environments. Required Qualifications Bachelor's degree in Computer Science, Software Engineering, Information Systems, or equivalent practical experience. 4-5+ years of professional software development experience building enterprise applications. Strong experience with C#, .NET/.NET Core, software design, and backend development. Experience building APIs, microservices, and cloud-native applications. Experience with modern frontend frameworks such as Vue, React, or Angular. Strong knowledge of SQL Server, PostgreSQL, MySQL, or similar relational databases. Experience with AWS or Azure, Terraform, CI/CD pipelines, source control, and modern software development practices. Recent hands-on experience incorporating AI capabilities into existing products, platforms, workflows, or production software. Strong problem-solving, communication, and collaboration skills, with the ability to balance engineering best practices and fast-moving AI technologies. Preferred Qualifications Experience with LLMs, RAG architectures, vector databases, embeddings, semantic search, AWS Bedrock, or similar AI platforms. Experience building conversational AI applications, copilots, assistants, or agentic workflows. Experience with Docker, Elasticsearch, Jenkins, or other cloud-native and DevOps technologies. Experience implementing monitoring, evaluation, and observability practices for AI-powered applications.
