Frontend Engineer (Next.js)

Pristina, Kosovo · In-Office About Sent Sent is building the messaging infrastructure that powers how businesses communicate with their customers. We provide a unified API for SMS, WhatsApp, iMessage, and RCS, making it simple for developers to reach people on any channel. We've raised $5.8M in funding and we're growing fast. The Role We're looking for a Frontend Engineer to build the interfaces developers and businesses use to interact with Sent. From dashboards to onboarding flows, you'll shape how customers experience the platform. What You'll Do • Build the product UI. Own and ship frontend features across Sent's web platform — dashboards, settings, onboarding, and more. Write clean, reusable components that work across devices. • Hold a high performance bar. Optimize for load times, rendering performance, and responsiveness. Users notice when things are slow. • Work closely with design and backend. Translate designs into production-ready code and collaborate with backend engineers to integrate APIs correctly. • Own the component architecture. Help define how components are structured, shared, and maintained across the codebase. • Ship fast. We move quickly. You'll be comfortable delivering features in a fast-moving environment without sacrificing quality. What We're Looking For • 3+ years of frontend development experience. You've worked in production Next.js or React environments and know how to ship things that hold up. • Strong expertise in JavaScript / TypeScript. You write typed code by default and understand why it matters. • State management and API integration. You know how to handle complex state and connect frontend applications to backend APIs cleanly. • Eye for design and UX. You care about how things look and feel, not just whether they work. • Experience building production-ready web applications in fast-moving environments. You've shipped and maintained real applications under real constraints. Why Sent We're a team building hard technical problems in messaging infrastructure. We value directness, craftsmanship, and actually shipping things. In Pristina, you'll be part of a close-knit engineering and operations team doing real work — not support work, not maintenance work. Work that matters. If you want to join a fast-moving company with a clear product and strong backing, this is that opportunity. Sent, Inc. is an Equal Opportunity Employer committed to building a diverse and inclusive team. We encourage applications from candidates of all backgrounds and experiences.
