Software Engineer, Trust & Safety

Responsibilities

• Build and run the real-time enforcement layer within a latency budget of milliseconds
• Design pipelines that move from signal to decision to action, across sending, receiving and account activity
• Build the detection rules and policies that decide when we act, and make them safe to change
• Detect and contain account takeover and leaked API keys: notice when a trusted account stops acting like itself, and stop the damage without locking out the real owner
• Close the feedback loop: every block and every reversal carries a reason, so we can measure each detection's precision and retire the ones that hurt good senders
• Automate manual work such as investigations, appeals and bulk actions, so the team keeps up as volume grows
• Build and evaluate ML classifiers for spam and phishing, and prove their precision before they enforce anything
• Implement safeguards and make every action traceable through logs, metrics and audit trails
• Ensure all enforcement actions are traceable with logs, metrics, and audit trails
• You’ll be a great fit if you...
