Jonathan Weiss is a Staff Software Engineer with 11+ years building durable, platform-scale systems and mentoring teams, currently steering platform work at ELMO after shaping Atlassian’s Forge as a senior engineer. He specializes in long-term architecture, cross-team alignment, and developer experience—authoring org-wide RFCs, delivering global rollouts like the Forge App UI Service and internationalisation, and closing migration gaps for vendors. Comfortable from API design to production hardening, he blends front-end craftsmanship (React/GraphQL) with platform thinking and operational rigor that kept zero SLO breaches in KTLO. A community-minded technologist, he runs meetups, champions accessibility and security practices, and brings a gardener’s patience to evolving systems and people. Outside work he balances endurance sports, travel and genre fiction with family life, reflecting a practical curiosity that informs his steady, people-first engineering leadership.
