About the role

Software Engineer on the Trust & Safety team responsible for detection, enforcement, and review systems to prevent abuse, fraud, malicious users, and illegal content on the OpenRouter platform. Owns proactive abuse-prevention architecture for a new AI stack layer, builds detection and enforcement pipelines, internal tooling, and analytics to protect platform trust and enterprise relationships.

Responsibilities

  • Build and operate technical systems across signup, payments, and usage to detect abuse and fraud early.
  • Own the technical enforcement pipeline end to end, from detection proposing a candidate to a human reviewing it to restrictions landing across our systems.
  • Build the internal tools that support investigation and enforcement decision-making. This involves building case queues, evidence summaries, bulk review and enactment, and alerting mechanisms to trigger investigations.
  • Ship technical solutions for content safety on the inference path: illegal content detection and reporting, the KYC systems or external intelligence sources to allow us to more efficiently and proactively detect and stop fraud and abuse.
  • Help make abuse uneconomical by building systems, tools, and heuristics for quick detection and scalable enforcement.
  • Help investigate incidents directly in the data and build the analytics plane so we can quickly establish what happened, size the pattern, and separate real abuse from a false-positive cluster.
  • Build defensible monitoring for risk, abuse spikes, and fraud, all while reducing false positives.
  • Set the technical direction for how we prevent abuse as the platform grows and evolves, and define the patterns other engineers build against.
  • Work with data scientists on feature exploration and training of risk and abuse ML models

Qualifications

  • 4+ years building and operating production systems, ideally including work in trust & safety, fraud, payments risk, security, or anti-abuse.
