About this role

OpenRouter is hiring a Software Engineer for the Trust & Safety team to build and operate detection, enforcement, and review systems. This remote position within the United States suits an experienced engineer ready to protect a major AI infrastructure platform against fraud and abuse.

Role Overview

This hands-on individual contributor role focuses on safeguarding the platform from malicious users, fraud, and illegal content. The position covers signup, payment paths, inference paths, and internal review tooling. The engineer will proactively architect abuse-prevention systems while balancing user friction for legitimate developers.

Key Responsibilities

Design and operate technical systems across usage, signup, and payments to identify fraud and abuse early.
Own the end-to-end technical enforcement pipeline from initial detection to human review and system-wide restrictions.
Develop internal investigation and enforcement tools, including case queues, evidence summaries, bulk review, and alerting.
Implement technical solutions for content safety on the inference path, incorporating KYC systems and illegal content detection.
Create heuristics, tools, and systems to make abuse uneconomical and enable scalable enforcement.
Investigate security incidents using data analytics to size patterns and minimize false-positive clusters.
Establish monitoring mechanisms for risk, fraud, and abuse spikes while maintaining low false-positive rates.
Define technical directions and design patterns for abuse prevention as the platform scales.
Collaborate with data scientists to explore features and train risk and abuse machine learning models.

Requirements

Four or more years of experience building and operating production systems, with background in trust and safety, security, anti-abuse, fraud, or payments risk.
Proficiency in JavaScript runtimes, Next.js, React, and TypeScript.
Capability to write SQL queries against large event datasets while reasoning about precision, recall, and decision costs.
Strong judgment when dealing with incomplete evidence and sensitive user data.
High agency, bias toward action, and comfort operating in a fast-paced environment with fluid team boundaries.
AI-forward workflow experience, utilizing coding agents and automation.
Excellent written and verbal communication skills for explaining detection rules and incident findings.

Nice to Have

Background in payments fraud tooling such as Stripe Radar, dispute flows, or crypto payment risk.
Experience with identity verification and KYC systems.
Familiarity with LLM-specific abuse patterns including prompt injection, jailbreaks, automated account farming, and key theft.
Experience managing large-scale analytical datastores like BigQuery or ClickHouse and observability platforms.
Knowledge of compliance and reporting obligations related to hosted AI and model provider policies.
Prior experience using OpenRouter or active side projects involving developer tooling and AI products.
