Safety Engineer - Free Tier Abuse

ElevenLabs is hiring a Safety Engineer to build and operationalize automated moderation and guardrail systems, especially to detect and prevent abuse of its free tiers. The role owns safety systems end to end, from architecture and deployment through monitoring and scaling.

Responsibilities:

• Design and build scalable backend infrastructure for abuse detection, deploying AI/ML models into production systems
• Architect robust APIs, data pipelines, and service architectures supporting real-time and batch moderation workflows
• Implement comprehensive monitoring, alerting, and observability systems; establish SLIs, SLOs, and performance benchmarks
• Partner with ML engineers to translate research models into production-ready systems and integrate them across our product suite
• Drive technical decisions and contribute vision to the safety roadmap on how the next generation of platform guardrails should be built for scale and precision

Requirements:

• Direct experience tackling free-tier abuse, fraud detection, or fake-account / bot farming at scale
• 6+ years of backend software engineering experience building production systems at scale
• Strong production backend experience: distributed systems, APIs, data pipelines, and Python expertise (asynchronous Python, backend frameworks)
• Infrastructure & DevOps proficiency: cloud platforms (AWS/GCP), containerization (Docker/K8s), CI/CD pipelines
• Observability mindset with experience in monitoring tools (Prometheus, Grafana) and building observable systems
• Track record of taking products or systems from 0→1 with measurable impact, including deploying or working alongside ML/AI systems in production
• Trust & Safety, Content Moderation, or Integrity engineering experience
• MLOps experience: deployment, monitoring, and versioning of ML models
• Experience with SQL, data analysis tools, real-time streaming systems (Kafka, Redis), or event-driven architectures
• Familiarity with React or modern frontend frameworks
