Austin, Texas, United States
Summary
🤩
Rockstar🎓
Top SchoolMatthew Jaffee is a Distinguished Engineer with 13 years of experience building high-performance backend systems and analytics databases, currently focused on combining novel database techniques and LLM-powered semantic search to make information more useful at Circuit. He helped evolve FeatureBase, a bitmap-powered analytical database for real-time ML and analytics workloads, contributing robustness, logging fixes, and performance optimizations to production backends. With a background that spans astrophysics to computer science, Matthew blends deep systems thinking with practical engineering—designing datapaths, architectures, and operational controls that prioritize security and data privacy. He has held hands-on leadership roles from engineering director to VP, and is driven by a long-term goal: to build software that outlives him. Based in Austin, he brings a track record of wrangling messy data pipelines into low-latency, highly concurrent systems that enable better decision-making.
