Senior🎓
Top SchoolTomas Sixta is a Senior Machine Learning Engineer based in Prague with 9 years of experience building production ML systems, currently leading development of a high-throughput email engine at Cisco that evolved from a 2020 startup-style project into a mature platform processing billions of messages monthly. He brings deep applied expertise in security-focused ML—specifically business email compromise detection—combined with a practical software engineering background from roles at Avast and an early data science internship in advertising. Tomas blends academic grounding from Czech Technical University and an Erasmus stint at KTH in computer security and machine learning with hands-on delivery at scale, often operating at the intersection of research, engineering, and product. Colleagues rely on him to turn ambiguous threat signals into reliable, production-ready models and pipelines that continually adapt to adversarial behavior.
