Summary

Senior🎓
Top SchoolLukas Karnowski is a software engineer with 12 years of experience specializing in high-performance systems, particularly in-memory and OLAP query engines. Based in Munich, he has led performance squads at Celonis, driving technical vision, multi-core task scheduling, and chunk-wise execution for a proprietary process query language implemented in C++. Comfortable in low-level languages like C++ and Rust, he blends algorithmic rigor from his database-focused academic background with hands-on optimization and troubleshooting. As a mentor and technical interviewer, he has coordinated distributed teams and shaped roadmaps that balance maintenance with forward-looking performance features. Currently at Firebolt, he continues to push runtime efficiency in analytic systems, bringing a pragmatic yet research-informed approach to engineering trade-offs. An early game-dev background and tutoring experience hint at a longtime habit of building practical systems while explaining complex concepts clearly.
