Senior Software Engineer Electron - Remote from Spain

Job Description

Key Responsibilities:

Own the lifecycle of our desktop app. You will manage publishing to app stores, code signing, notarization, and safe auto-updates for our global user base.

Design and maintain robust CI pipelines (GitLab CI). You will implement automated testing strategies for Electron, collaborating with our staff QA engineer, to prevent regressions before they reach production.

Safely navigate major version bumps of Electron and Chromium, anticipating breaking changes and managing the impact on device management and memory usage.

Debug and optimize the application’s performance, focusing on memory leaks and CPU usage in a desktop environment, critical for maintaining a high audio quality during calls.

Maintain and extend native integrations with USB telephony hardware (Jabra, Plantronics, Yealink headsets) for call control and presence features.

Participate in an on-call rotation to respond to critical system issues.

Our Desktop Tech Stack: You'll work with mature tooling for cross-platform desktop development:

Electron 35+ (actively tracking latest stable releases)

electron-builder for multi-platform packaging (NSIS, MSI, Squirrel installers)

electron-updater for safe, differential auto-updates across our global user base

Vite for fast builds and hot module replacement during development

TypeScript for type-safe main and preload processes

Node.js native modules (node-hid) for USB hardware integration

GitLab CI for automated builds, code signing, and release pipelines

AWS for build artifact distribution and crash reporting

RxJS for reactive event handling

Code signing: @electron/notarize (Mac), custom esigner.js (Windows)

Modern developer experience with AI-assisted development (Cursor, Claude), fast CI/CD, type-safe workflows

We maintain installers for both macOS (signed, notarized, hardened runtime) and Windows (NSIS, MSI with per-machine installs).

Qualifications:

You have at least 5+ years of experience, with deep expertise in Electron and the Node.js ecosystem.

You have proven experience building and maintaining CI/CD pipelines (GitLab CI preferred) for desktop applications.

You know the ins and outs of code signing (Apple/Windows) and auto-update mechanisms.

You have experience establishing E2E testing strategies for desktop applications using tools like Playwright or Cypress.

You stay current with modern development practices and tooling, including AI-assisted development tools, to maximize your productivity.

You are rigorous about security and understand the implications of browser versions and third-party dependencies.

You prefer robust, automated solutions over manual processes.

You are autonomous and capable of delivering complex infrastructure projects on time.
