Job description
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.
