Our customers rely on Reality Defender to make high-stakes calls in real time — whether the voice on a bank's phone line or the face in a job interview is real. As a Quality Assurance Engineer, you'll make sure what we ship holds up to that standard, testing our APIs, SDKs, web app, and real-time integrations, and building the automation that lets us release faster without breaking things. This is a full-time role based at our NYC headquarters or remote within the U.S., reporting to Quality Assurance Lead. Responsibilities include: Own test planning and execution for assigned product areas — APIs, SDKs, the web app, and real-time voice and video integrations — from requirements review through release sign-off. Build and maintain automated test suites (API, end-to-end, and regression) and integrate them into our CI/CD pipelines. Find, document, and track defects with clear reproduction steps, severity, and impact, and work with engineers through to resolution. Test the reliability and performance of real-time detection under realistic conditions — latency, load, varied audio and video quality, and different platforms and devices. Help maintain the test data and media sets used to validate each release. Partner with the AI Research and Red Team to support model release validation and regression testing. Help Customer Support and Solutions Engineering reproduce and triage customer-reported issues. Contribute to QA standards, documentation, and release checklists across the engineering team.
