Principal Software Engineer at Elastic
Malmo, Sweden
Summary
🤩
RockstarMarius Iversen is a Principal Software Engineer based in Malmö with over a decade of hands-on experience focused on security, integrations, and large-scale monitoring in enterprise environments. He combines deep expertise in SIEM/SOC design, network and application-level security, and Elastic Stack development—contributing backend integrations and a GenAI-powered "Integration Assistant" plugin to Kibana. His background spans ethical hacking, log parsing, edge-to-pipeline ingest migrations, and automation across dozens of integrations, giving him a rare full-stack view of security data flows. Colleagues know him for an almost obsessive commitment to best practices and robust architecture that sometimes borders on pedantry. Outside of work he continues to tinker with open source, learn new technologies, and contribute to security tooling—proof that his childhood curiosity for how things work never faded.
