About the role

Role focused on building anti-abuse systems to keep Resend open for good senders and closed to bad actors, including real-time enforcement, scalable detection pipelines, and automated actions with traceability.

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

Qualifications

  • 5+ years of software engineering experience
  • Fluent in English (reading/writing)
  • Deep experience with Node.js, TypeScript, React (Hono, Next.js)
  • Ability to write Go, or interest in learning for latency-sensitive services
  • Infrastructure and reliability skills (AWS, CDK, Datadog)
  • Comfort with APIs, event-driven architectures, queues and stateful services
  • Designing systems that fail safe and treat false positives as bugs
  • Strong observability mindset: metrics, logs, tracing, error handling
  • Ownership across the stack from frontend to databases and queues
  • Experience with databases (Postgres, Redis)
