About The Company

Wire is a secure messenger and collaboration platform built for organizations that cannot afford leaks, exposure, or loss of control. We help governments, critical infrastructure, and enterprises replace insecure messaging, reduce shadow IT, and take back control of their communications. It brings together messaging, voice, video, and file sharing in one workspace, protected by strong, always on end to end encryption. ❌ The reality today Most collaboration tools were not designed for security. They expose data, create dependency on non sovereign providers, and leave gaps in compliance. ✅ What Wire does differently – End to end encryption is always on across messages, calls, and files – No one can access your data, not even Wire – Flexible deployment across EU cloud, private cloud, on prem, or air gapped environments – Encryption based on the Messaging Layer Security standard, built to scale without friction Unlike traditional tools, Wire is built so that security does not depend on trust in the provider. It removes data access, reduces sovereignty risk, and gives organizations full control over their communications. ➡️ Where it matters most – Crisis and incident communication – Confidential workflows across legal, executive, and security teams – Frontline and cross organization coordination without consumer apps ✅ The result Secure, sovereign collaboration your teams can actually use without compromise. Book a demo and see how Wire fits into your security and IT environment and replaces insecure communication tools.

YOUR CHALLENGE AT WIRE

As a Senior Software Engineer - Web at Wire, you’ll drive technical direction across our React-based apps and our Electron-based desktop client. You’ll collaborate closely with Product, Design and other Development teams to translate complex requirements into robust technical solutions.

WHAT YOU WILL DO IN DETAILS

Real-time messaging and encrypted media exchange using cutting-edge standards like MLS
Performance-focused improvements on message processing, rendering, synchronization, and offline-capable workflows across platforms and sessions
Leading technical initiatives with Senior Engineers, Staff Engineer and Engineering Manager to improve architecture and developer experience
Defining and driving technical initiatives that improve app scalability, reliability, and maintainability — including modernizing legacy areas
Driving architectural decisions and raising the technical bar through well-reasoned RFCs and ADRs, thoughtful code reviews, and a collaborative, communicative mindset
Supporting and mentoring other engineers — helping them grow, share context, and take on broader ownership

YOUR PROFILE

You’ve built and maintained complex frontend systems across web and desktop environments and know what it means to carry a feature from rough idea to production. You think in systems, advocate for your decisions with clarity, and know how to move teams forward — even when the path isn’t obvious.

Technical Skills

Expert-level knowledge of React and frontend architecture
Hands-on experience with Electron, including security constraints (IPC design, preload boundaries, protocol handling, signing/notarization) is a strong plus
Strong experience diagnosing and fixing performance and memory issues in real-time applications — including large lists, background processing, CPU vs memory trade-offs and data-processing flows.
Experience working with local client-side databases (e.g., IndexedDB or alternatives), Web Workers, WASM-based libraries, and large in-browser data sets
Familiarity with secure messaging protocols (e.g., MLS, WebRTC, or E2EE media flows) is a strong plus
Experience working in modular and multi-package codebases, including monorepos, using tooling like Webpack, npm scripts, and shared frontend infrastructure
Experience owning or significantly contributing to CI/CD and release pipelines (GitHub Actions, Jenkins)
Strong testing practices with unit, integration and e2e test coverage (e.g., Playwright)

Soft Skills

You are fluent in English and can contribute effectively to an international team.
You mentor by providing context, not just answers — helping others build judgment, not dependency.
You can break down complex trade-offs and drive alignment without shutting down alternative views.
You are proactive — when you spot tech debt or poor architecture, you don’t wait for someone to ask. You take initiative.
You take ownership of problems you didn’t create — and see them through to resolution.
You challenge ideas rigorously while remaining respectful — and expect the same from others.
