Senior Frontend Developer

We’re AD/01, the tech studio that builds the future of food retail. Whether it’s in-store aisles, online baskets, or behind-the-scenes operations, we innovate the daily food experiences for farmers and families, grandmas and greengrocers, and pickers and packers alike.

And we’re looking for the freshest minds excited to create the recipe for change.

As a Senior Front-End Developer, you will work on a multi-brand, white-label web platform that supports localized eCommerce experiences across several Ahold Delhaize brands in Europe.

• Build and maintain an internal store-operations dashboard for store staff: orders, picking, timeslots, shifts and inventory
• Build to accessibility (WCAG) standards
• Monitor and improve real-user performance: track Core Web Vitals through CrUX field data and Dynatrace RUM, find regressions, and ship fixes that move the p75 score per banner and market
• Participate in code reviews and technical discussions
• Support internationalization across multiple country markets
• Monitor and improve performance (Core Web Vitals, bundle size)
• Collaborate with backend teams on Hybris integrations
• Work closely with DevOps on environment and deployment topics
