AI Engineer – RAG Platform
About the role
As an AI Engineer focused on a Retrieval-Augmented Generation (RAG) platform, you will improve the system’s quality, accuracy and effectiveness through data-driven experimentation and measurable improvements.
You will work at the intersection of information retrieval, data science and software engineering. Your focus is improving the performance of the RAG system itself by identifying where and why it underperforms, testing potential improvements and translating findings into production outcomes.
You will contribute throughout the improvement lifecycle, from failure analysis and hypothesis generation to evaluation, implementation and monitoring. You will use user feedback, retrieval metrics, evaluation datasets and production telemetry to improve answer quality and user trust.
What you’ll do
Improve retrieval performance, answer quality and the overall user experience through analysis, experimentation and optimization.
Investigate low-quality answers and identify underlying retrieval or grounding issues.
Develop automated evaluation frameworks to measure retrieval quality, answer quality and user satisfaction, identify regressions and provide actionable insights.
Run large-scale experiments to assess chunking, embedding and retrieval strategies.
Analyze user interactions and system performance data in Databricks to identify opportunities for improvement.
Build feedback loops that identify weak responses and feed insights into development.
Define and monitor quality metrics so releases deliver measurable improvements.
Translate analysis and experimentation into scalable, maintainable engineering solutions.
Work closely with software engineers, platform engineers, data scientists and product managers.
What you’ll bring
A master’s degree or equivalent academic level in Data Science, Artificial Intelligence, Computer Science, Mathematics, Statistics or a related field.
At least three years of relevant experience in machine learning, applied AI or data science.
Demonstrable experience improving production-grade RAG systems or advanced retrieval-based AI solutions.
Experience designing evaluation methodologies and quality metrics.
A strong track record of turning analysis into automated production solutions.
Experience working with large datasets and complex distributed environments.
The ability to communicate findings and recommendations to technical and non-technical stakeholders.
Proficiency in written and spoken English.
A curious, analytical approach and a focus on taking ownership of measurable outcomes.
Technical skills
Retrieval-Augmented Generation (RAG) and large language models (LLMs)
Python and Databricks
Evaluation frameworks for generative AI systems
Embedding models and prompt optimization
Data pipelines and workflow automation
CI/CD practices and Azure
Nice to have
