Senior🎓
Top SchoolJérôme Brongniart is an Observability Engineer based in Zurich with over a decade of hands-on experience bridging performance engineering, DevOps, and observability for Swiss banks, insurers, and startups. He began as a performance engineer, running large-scale load campaigns and building small specialist teams, and progressed to lead DevOps and consulting roles where he established CI/CD, test automation, and cloud-native delivery patterns. Jérôme has a track record of solving tricky integration problems—such as orchestrating mixed Selenium/Appium fleets across public and private clouds to simulate realistic authentication at scale—and has owned both backend development and product work. Comfortable on the command line and in customer-facing roles, he routinely translates business requirements into auditable, automated test and monitoring pipelines. His academic background in combinatorial optimization and PhD-level research informs a methodical approach to performance and observability challenges. Now at Julius Baer, he focuses on elevating observability practices in complex, regulated environments while keeping a practical engineer’s eye for automation.
