Summary
🤩
Rockstar🎓
Top SchoolJon Pither is a seasoned software leader and co-founder who has spent 13+ years building and guiding high-performance engineering teams as CEO of JUXT, a consultancy delivering opinionated technology solutions to large enterprises. He combines hands-on Clojure expertise—demonstrated by work on the widely used CIDER Emacs tooling—with strategic delivery oversight across finance, media, and public infrastructure projects that scaled to millions of users. Jon has repeatedly led migrations and greenfield builds (from risk systems at Credit Suisse to national bike-share software and a major UK property portal), often bootstrapping teams and practices to sustain long-term success. His background blends technical leadership, delivery governance, and developer coaching, with a pragmatic focus on test automation, data access patterns (GraphQL/Datomic) and resilient operational software. Based in Dacorum, England, he still finds time for community engagement—speaking at EuroClojure and attending Clojure/Conj—reflecting a sustained commitment to the ecosystem he hires and mentors from. Colleagues would describe him as a founder who prefers solving knotty engineering problems by pairing strong opinions with hands-on contribution.
