What You Will Do Design and deploy scalable ML systems using modern MLOps practices, including real-time inference, model monitoring, and automated retraining pipelines. Architect agentic AI systems capable of autonomous threat detection, adaptive policy enforcement, and self-healing security responses. Build tools for model development , debugging, and explainability to accelerate iteration and transparency. Optimize ML workflows for distributed environments to handle large-scale data processing. Collaborate cross-functionally with security analysts, backend/frontend engineers, and customer support to align technical solutions with user needs. Advance the state of ML for anti abuse and account security , exploring cutting-edge techniques like adversarial robustness, graph-based anomaly detection, and privacy-preserving AI.
Join Proton and build a better internet where privacy is the default Proton was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right . Since then, we’ve built the world’s largest encrypted email service (Proton Mail) and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar—tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, Proton has literally helped save lives! We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Our 500+ team members across 50+ countries come from leading organizations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritize impact over optics. If you want to do meaningful work with exceptionally high-caliber people, this is it. Join us and do work you can truly be proud of. Check our open-source projects here !
