❗️ English - В2
**Our requirements (Hard Skills):**
✔️**Angular 21+** with deep understanding of RxJS, Signals, and Change Detection.
✔️Proven experience with complex data grids (AG Grid, PrimeNG, or custom-built solutions).
✔️ Performance profiling and optimization (Lighthouse, Chrome DevTools).
✔️**Angular Material** at an expert level (theme customization, reusable component design).
✔️Solid understanding of REST API integration.
**Nice to have:**
➕ Experience with **OpenLayers, Leaflet, or Mapbox** (markers, polylines, geo-layers).
➕ Hands-on experience with **WebSockets** ([Socket.io](https://socket.io/) or native) — connection management and real-time data streams.
**We offer:**
✔️ Salary up to **€7000** (gross) — negotiable based on interview results.
✔️ Official employment under Lithuanian labor law.
✔️ Modern office in the heart of Vilnius with full benefits package.
✔️ Work on a product company with technically challenging tasks.
