Jonas Rosland is an open source and community-focused technology leader with 13 years of experience building developer ecosystems, currently serving as Open Source and Technical Marketing Director in Boston. He blends hands-on front-end and documentation work—migrating sites to Hugo, adding SEO and search for Kubernetes projects like Contour and Sonobuoy—with strategic community leadership roles at VMware, VAST Data, CIQ and Dell. Jonas has led major programs launching corporate open source initiatives, creator-facing training, and community-first governance models that scaled Slack communities and outreach programs. He is comfortable shipping UI and site revamps for prominent CNCF-related projects and improving discoverability for technical docs, a combination that helps translate developer needs into measurable marketing and product outcomes. Notably, his background includes both classroom teaching and deep technical delivery (from Solutions Architect roles to developer advocacy), giving him a rare mix of pedagogy, engineering craft, and community strategy.
