Julien Herzen is a Sr Engineering Manager at Isomorphic Labs in Lausanne with about 10 years of experience building production ML and data platforms. He created and led development of Darts, a widely used open-source Python library for time series forecasting and anomaly detection, and remains an active contributor to its modular, PyTorch-backed codebase. With a PhD in network algorithms from EPFL, he blends rigorous research with production engineering—having built a 30+ node networking testbed and production pipelines at Swisscom handling millions of data points per second. As a former Area Director at Unit8 he helped scale the company from a handful of people to over a hundred while driving product and technical strategy. An unusual but telling detail: summers spent driving heavy trucks shaped his knack for logistical thinking and pragmatic optimization, a theme that runs through his work in distributed systems and time series ML.
