Responsibilities


🚀 What You’ll Achieve (Outcomes) In your first 3–6 months, you’ll: * Launch key features (group chat, P2P calls, channels, integrations) in Flutter across iOS and Android to help us reach our first 50,000 installs. * Improve and maintain app stability, targeting <1% crash rate and resolving all critical bugs within 72 hours. * Elevate code quality, refactoring for modularity, test coverage, and future contributor onboarding. * Design usable privacy features, like encryption key verification and secure device flows that feel intuitive to users. 🧠 What You Bring (Core Competencies) * Technical excellence in Flutter/Dart; you write clean, reliable, cross-platform code for the past 3–5 years. * Location: Europe. * Bonus: Experience with Matrix.org or other messaging platforms. * Execution and ownership; you take initiative and see features through. * Empathy for privacy-conscious users and fellow developers reading your code. * Attention to detail, essential for security, UX, and app stability. * Communication and documentation skills for async collaboration and open-source work. ⚙️ Our Tech Stack: * Flutter (Dart) * Matrix.org Synapse * Google Cloud * Firebase You’ll work alongside engineers contributing to both mobile and backend systems. 🎁 What’s in it for You * Equity in a mission-driven company building toward funding and scale. * Collaboration with a real team, including mobile, backend, and anti-abuse engineers. * Total ownership over meaningful features used by real people. * Remote-first culture across Europe, async-friendly and with minimal meetings. * Work on a privacy product that people care about. * Opportunity to grow into a foundational role as the team raises and scales. 🙋 Who This Is For * You’ve shipped Flutter apps and care about real-world impact. * You’re comfortable working in a pre-funding, equity-only role. * You want to build something with purpose, not just complete tasks. * You’re excited about privacy, open protocols, and ethical tech. ⚠️ Read Before You Apply This isn’t a corporate role. There’s no salary (yet). There’s also no bureaucracy, no unnecessary meetings, and no meaningless metrics. Just builders shipping privacy-first software together.
