Julius Volz is the founder of PromLabs and a driving force behind Prometheus, the widely adopted open-source monitoring and time-series database he created while at SoundCloud. With 26 years of experience across systems engineering, SRE, and backend development, he combines hands-on technical leadership with product-focused entrepreneurship, currently building tools like PromLens to make observability more accessible. His work spans low-level kernel contributions (IPv6 support for IPVS) to large-scale production systems at Google and SoundCloud, and deep involvement in core Prometheus components such as the server, client libraries, Alertmanager, and exporters. A prolific open-source maintainer and release engineer, he emphasizes robustness, performance, and developer ergonomics—evident in contributions that improved storage, ingestion, and observability UX. Based in Berlin, he pairs a pragmatic engineering mindset with years of teaching and consulting on monitoring best practices.
