Join a fully remote engineering team based in Switzerland building reliable email infrastructure for millions of developers worldwide. As a Software Engineer specializing in Trust & Safety, you will design and develop anti-abuse systems that protect legitimate senders while preventing spam, phishing, fraud, and account compromise. You will build real-time enforcement mechanisms, scalable detection pipelines, and automated workflows that turn security signals into effective actions within milliseconds. Working across backend services, infrastructure, databases, and machine learning, you will strengthen platform security without compromising the user experience. You will have significant ownership over technical decisions from discovery through production deployment in a quality-focused, collaborative, and globally distributed environment.

Accountabilities: - Build and operate real-time enforcement systems that evaluate and act on potential abuse within millisecond-level latency requirements. - Design scalable detection pipelines that transform signals from email sending, receiving, and account activity into decisions and automated actions. - Develop, maintain, and improve detection rules and enforcement policies, ensuring they can be updated safely and evaluated consistently. - Detect and contain account takeovers and leaked API keys by identifying suspicious behavioral changes and limiting potential damage while avoiding unnecessary account lockouts. - Establish feedback mechanisms that record the reasons behind enforcement decisions and reversals, measure detection
