Engineer I: AI Engineer

RTX is an aerospace and defense company developing aircraft engines, auxiliary power systems, and advanced engineering capabilities. The company is seeking an AI Engineer to design, build, test, and scale production-grade enterprise AI applications using large language models, retrieval-augmented generation, intelligent agents, and modern software engineering practices.

What you'll do:

• Design, build, test, and deploy production-grade AI applications and services
• Develop LLM-powered applications, intelligent agents, and agentic workflows
• Build and improve retrieval-augmented generation (RAG) systems
• Integrate AI applications with APIs, databases, enterprise systems, tools, and knowledge sources
• Develop reusable AI services, APIs, components, and frameworks
• Implement tool calling and multi-step workflows that enable AI systems to complete complex tasks
• Improve semantic search, embeddings, retrieval, reranking, and contextual grounding
• Apply prompt engineering and context engineering techniques to improve AI system performance
• Develop evaluation methods to measure accuracy, relevance, groundedness, reliability, latency, and user experience
• Identify and mitigate hallucinations, retrieval failures, and other common AI system failure modes
• Prototype and evaluate emerging AI technologies for enterprise use
• Contribute to AI observability, monitoring, testing, security, governance, and responsible AI practices

What they're looking for:

• U.S. citizenship is required, as only U.S. citizens are authorized to access information under this program/contract
• * Bachelor's degree in Computer Science, Software Engineering, Artificial Intelligence, Machine Learning, Data Science, Computer Engineering, Mathematics, or a related technical discipline
• * Experience programming in Python
• * Understanding of software engineering fundamentals, including data structures, APIs, testing, object-oriented programming, and version control
• * Foundational understanding of machine learning, artificial intelligence, and generative AI concepts
• * Experience with Git or similar version-control technologies
• The successful candidate for this role will be required to reside and work from one of the 50 U.S. states (excluding U.S. territories)
• * Prior RTX internship, co-op, or work experience
• * Experience building applications using large language models
• * Experience working with platforms or APIs such as Azure OpenAI, OpenAI, Anthropic, or similar technologies
• * Experience with retrieval-augmented generation architectures
• * Experience with embeddings, vector databases, semantic search, hybrid search, or information retrieval

Benefits:

• Remote: This position currently is designated as remote. Employees who are working in remote roles will work primarily offsite (from home) but may be expected to travel to the site location as needed. The successful candidate for this role will be required to reside and work from one of the 50 U.S. states (excluding U.S. territories).
