My Professional Experience | Jason Sonderman, UXMC

Head of UX

Arcos builds SaaS and mobile workforce management platforms for utilities and critical infrastructure.

Built the UX function from scratch — grew the team from myself plus two contractors to three Senior Designers and a consultant, establishing hiring criteria, design culture, and a Ways of Working framework that made the team legible to engineering and product leadership.
Pioneered an AI-accelerated delivery model — designed and operationalized a pipeline where UX moves from Discovery through design to draft front-end code entirely within the design team, compressing handoff cycles and enabling higher-fidelity collaboration with engineering.
Led discovery for the Lighthouse Platform, an Emergency Preparedness MVP — synthesized field research into a product vision that reframed the roadmap. User testing shaped scope decisions before any front-end code was written.
Served as strategic UX partner through a product acquisition — aligned design standards across the legacy Arcos product and the Clearion acquisition, establishing UX as a voice in product strategy conversations, not just a delivery function.

Led strategic redesign of the global e-commerce platform using UCD, Double-Diamond, and Design Sprint methodologies — increasing user engagement by 20% through a research-grounded, iterative process.
Built and scaled a team of 8 UX Designers across Belgium, the US, and India — establishing UX values, working principles, and a design culture that operated cohesively across time zones.
Implemented enterprise-level discovery infrastructure: live customer sessions for pre-release validation, session recordings, and behavior metrics to drive evidence-based design decisions.
Architected design system strategy — refined the Figma component library and developed a CSS token system, reducing development time by 35% across two major platforms.
