Have you ever used two-factor authentication, received a real-time delivery notification, or joined a voice/video call directly from an app? Chances are, the technology behind it was built by the company we’re collaborating with—a globally recognized leader in cloud-based communication services.
We’re currently looking for an experienced Technical Lead (Fullstack Java) to join and guide one of our product teams developing scalable, globally used solutions. As a Tech Lead, you’ll take ownership of the system architecture, mentor other engineers, and drive key technical decisions — while staying hands-on with development.
The tech stack is heavily backend-focused, with about 90% Java work and around 10% frontend using Vue.js. If you have experience with React and are interested in switching to Vue, this is a great chance to broaden your skillset while leading a strong, collaborative team. Depending on your profile and preferences, we’ll assign you to the project that best aligns with your expertise.
