Senior React/Electron Desktop Engineer (Secure Messenger) - Remote

Description

Position : Senior React/Electron Desktop Engineer (Secure Messenger) - Remote

We are hiring a Desktop Engineer to own and strengthen the Electron-based desktop client of our secure messenger. Your primary mission is to ensure a stable, performant, and secure desktop experience and reliable synchronization with the rest of the system (in particular via XMPP/WebSockets) while working closely with our Android and iOS teams.
Key Responsibilities:

  • Develop and maintain the desktop client using Electron + React + TypeScript.
  • Ensure reliable real-time communication and synchronization with the backend and mobile clients (XMPP/WebSockets).
  • Design and implement robust connection health behavior (heartbeats, reconnect logic, backoff strategies, offline handling).
  • Improve UI performance for large datasets (chat lists, long message threads) using virtualization and efficient rendering strategies.
  • Work with local data storage (SQLite) and write efficient queries for pagination, filtering, and fast loading (avoid “load-all-and-sort-in-JS” patterns).
  • Collaborate with mobile engineers (Android/iOS) to ensure feature parity and consistent behavior across clients.
  • Contribute to security best practices (safe handling of sensitive data, minimal logging exposure, secure client boundaries).
