Summary
👤
Senior🎓
Top SchoolSimon Johnston is an Associate Technical Fellow with over three decades of engineering and product experience, currently shaping technical culture and large-scale systems at Walmart Global Tech after a 16-year tenure at Amazon. He combines deep distributed-systems and retail-domain expertise—from early point-of-sale device drivers to architecting cloud-native, high-scale retail and advertising platforms—while still enjoying hands-on coding. Simon has driven architecture and standards work at IBM and Microsoft, including Linked Data, SPARQL, and industry XML/UML standards, which gives him a rare blend of pragmatic engineering and standards-driven design. Known for mentoring engineers and aligning cross-organizational architecture, he emphasizes integrity and respect as operational values that improve hiring and onboarding. Based in Bellevue, WA, he brings a consistent track record of translating complex business problems into scalable, service-oriented solutions across physical and digital retail. An underappreciated strength is his long-running ability to bridge standards, product management, and implementation—making him equally effective in specification rooms and production deployments.
