About The Position

Quantum Research International, Inc. (Quantum) is seeking an Intermediate Software Developer/Engineer to support the development and enhancement of a Retrieval-Augmented Generation (RAG) application that leverages Large Language Models (LLMs) for intelligent inference and response generation. This is a government contract role focused on building secure, reliable AI-assisted systems. The ideal candidate has strong software engineering skills across multiple languages and a solid understanding of AI/ML concepts, with hands-on interest in applied LLM technologies.

Requirements

• Active TS or ability to obtain TS/SCI clearance
• At least 3+ years of professional software development experience
• Strong experience in at least two of the following: .NET/C#, Go (Golang), Python. Solid understanding of all languages listed is a plus.
• Familiarity at the developer level with AI/ML fundamentals, including embeddings and vector searching, RAG patterns, LLM inference (prompting, context windows, token management), and basic evaluation metrics for generative AI.
• Experience building RESTful APIs, microservices, or backend systems.
• Experience with non-frontier (open) AI models running in local or self-hosted environments.

Nice To Haves

• Direct experience developing and deploying AI-assisted applications (chatbots, knowledge assistants, document intelligence tools)
• Hands-on work with RAG frameworks/tools such as LangChain, LlamaIndex or similar.
• Experience implementing vector databases such as Pinecone, Weaviate, Chroma, pgvector, etc.
• Familarity with Python data/AI ecosystem (NumPy, Pandas, Hugging Face, sentence-transformers)
• Knowledge of .NET integrations with AI services or Go-based backend services for high-performance AI workloads
• Experience developing in secure/controlled environments (FedRAMP, gov-cloud, air-gapped enclaves).
• Understanding of MLOps basics (model versioning, monitoring, CI/CD for AI).

Responsibilities

• Design, develop, and maintain RAG pipelines integrating vector databases, embeddings, and LLMs for accurate, context-aware inference.
• Implement and optimize retrieval logic, prompt engineering, and post-processing of LLM outputs.
• Build and integrate backend services using .NET/C#, Go, and/or Python.
• Collaborate with AI/ML engineers, data scientists, and stakeholders to translate requirements into production-grade features.
• Ensure application security, performance, scalability, and compliance with government standards.
• Troubleshoot and optimize AI-assisted workflows, including latency, accuracy, and cost considerations.
• Participate in code reviews, testing, and documentation in an Agile environment.
