Senior Mobile Developer (Flutter)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Mobile Developer (Flutter) based in Portugal. This is a high-impact opportunity to own the mobile experience of a digital retail ecosystem used in demanding, real-world store environments. You’ll build a high-performance mobile application connecting directly with payment terminals, printers, barcode scanners, and other specialized hardware. The role goes beyond conventional app development, combining Flutter with native Android/iOS capabilities through an Add-to-App architecture. You’ll help deliver critical features spanning point-of-sale, billing, inventory, banking, B2B commerce, and AI-powered user assistance. A strong focus on offline-first architecture, reliability, speed, and seamless checkout experiences makes this a technically challenging role. You’ll work closely with Product and Backend teams in a fully remote, international environment where autonomy and ownership are highly valued. It’s an excellent fit for an experienced Flutter developer who enjoys solving complex technical problems and building products with tangible everyday impact.
