Full Stack Engineer
Department: Engineering
Location: Kosovo
Employment Type: FullTime
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 Full Stack Engineer who can move across the entire product — designing APIs and shipping UI with equal confidence. You'll take ownership of end-to-end features that touch every layer of the Sent platform.
What You'll Do
• Own features end-to-end. Take requirements from design to delivery — backend API, frontend UI, database, and everything in between.
• Work across both stacks. Build and maintain services in .NET / ASP.NET Core on the backend and Next.js / React on the frontend. Comfortable in both without being precious about either.
• Integrate with the broader system. Connect to carrier networks, internal services, and third-party APIs. Understand how your features fit into the larger architecture.
• Move fast without breaking things. Ship regularly and take responsibility for what you build. Write tests, observe your deployments, and fix what breaks.
• Bring a product mindset. Think about what you're building and why. Push back when something doesn't make sense and suggest better approaches when you see them.
What We're Looking For
• 3+ years across both frontend and backend development. Not a preference — you actually do both.
• Hands-on Next.js / React and .NET / ASP.NET Core. You've shipped real features in both stacks.
• Experience with APIs, databases, and integrations. You understand how systems connect and what it takes to make them reliable.
• Scalability awareness. You think about what happens when load increases before it happens.
• Strong product instincts. You're not just building what's on the ticket. You're building the right thing.
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.
