Summary
👤
Senior🎓
Top SchoolJay Mcnallie is a founder and seasoned software leader with 11 years of experience building open-source data integration solutions for DoD, intelligence community, coalition, and commercial users. He has led product and engineering teams—most recently steering technical product development and a 15-person team at Octo—while transitioning organizations from services to product-focused models. Deeply hands-on, Jay has contributed to the widely used Distributed Data Framework (DDF), implementing cache management, Solr integrations, and CQL search enhancements that improved large-scale data retrieval. His background spans systems engineering, DevSecOps, and enterprise integration across ISR and geospatial domains, with repeated program growth and delivery under SAFe practices. Based in Phoenix, he combines strategic program leadership with practical engineering mentorship, and he often bridges R&D work into fielded capabilities for military and government customers. Not obvious from titles alone: he routinely turns open-source R&D into commercial and operational wins, including first commercial sales and NATO-interoperable extensions.
