About BigRio

BigRio is a Boston-based, remote-first technology consulting firm specializing in advanced data and software solutions. We partner with forward-thinking organizations to deliver scalable, cost-effective, and innovative technology, with particular expertise in AI/ML, data engineering, and cloud-native applications. Our clients span healthcare, life sciences, government, and enterprise sectors, and we are known for our ability to tackle complex challenges with cutting-edge solutions.

About The Role

BigRio is seeking a highly skilled Generative AI Engineer with expert-level experience in LLMs , OpenAI APIs , prompt engineering , and retrieval-augmented generation (RAG) . This is a senior, hands-on role —ideal for someone who has already mastered these technologies and is ready to deliver production-ready solutions. This is not a learning-on-the-job position.

You will work with our internal team and clients to design, build, and optimize AI-powered applications with high-performance standards and robust infrastructure integration.

Key Responsibilities

Design and implement LLM-driven features using OpenAI API (including reasoning vs. non-reasoning models, model versioning, temperature settings, and best practices). Apply advanced prompt engineering and model tuning techniques to drive performance and accuracy. Build retrieval-augmented generation (RAG) systems using Langchain and ChromaDB. Develop interactive AI tools and UIs using Gradio. Ensure seamless SSO integration and secure access controls. Implement Dockerized environments for scalable deployments. Connect and automate data pipelines including Google Drive integration. Write clean, maintainable code in Python, and contribute to a collaborative, agile development environment.

Required Qualifications

3-5+ years of experience in AI/ML development, with proven, expert-level hands-on work in LLMs and Generative AI. Mastery of the OpenAI API, including reasoning capabilities, temperature control, and fine-tuning parameters. Deep experience with prompt engineering and AI response optimization. Strong Python development skills. Production-level experience with Langchain, ChromaDB, and RAG architectures. Proficiency with Gradio for front-end prototyping. Experience with Docker, SSO, and cloud API integrations (e.g., Google Drive). Strong problem-solving and communication skills. Comfortable working independently and collaborating across time zones.

Nice to Have

Experience with other vector databases and frameworks. Familiarity with MLOps or AI infrastructure tooling.
