Quality Assurance Engineer

NYC HQ or Remote (U.S.) | Full-time | Engineering | Reports to: Quality Assurance Lead

WHO WE ARE.

Reality Defender is an award-winning AI company that develops models to help enterprises and governments tell what’s real from what’s AI-generated. Our multi-model platform detects AI-generated video, audio, and images in real time, and stays robust against new generative tools as they emerge.

The question our customers are asking is changing. It’s no longer only “is this a deepfake?” It’s “is this real, and is it who it claims to be?” Every day, organizations ask us:

• “Is the voice on this call a real person?”
• “Is that video of our CEO real?”
• “Is everyone in this meeting who they say they are?”

We answer those questions in real time, across video, audio, images, and text, so security teams can act before the damage is done.

Reality Defender is backed by world-class investors including DCVC, Illuminate Financial, Y Combinator, Booz Allen Hamilton, IBM, Accenture, Rackhouse, and Argon VC. We work with leading enterprises, financial institutions, and government agencies to make sure AI-generated media can’t be used to deceive.

THE QUALITY ASSURANCE ENGINEER ROLE.

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.

WHO YOU ARE.

• 3+ years of experience in software QA or quality engineering, testing web applications and APIs in a fast-moving release environment.
• Hands-on experience writing automated tests in Python, JavaScript/TypeScript, or similar, using frameworks such as Pytest, Playwright, Cypress, or Selenium.
• Experience testing REST APIs (e.g., Postman or code-based API tests) and working within CI/CD pipelines (e.g., GitHub Actions).
• Strong attention to detail and a systematic approach to finding edge cases — you think about how things break, not just whether they work.
• Clear written communication: your bug reports and test plans are easy for engineers to act on.
• Experience testing audio, video, or real-time communication products (WebRTC, telephony, conferencing). (nice to have)
• Experience testing ML-powered products or working with test datasets. (nice to have)
• Exposure to performance or load testing tools (e.g., k6, Locust, JMeter). (nice to have)

• Own QA for multiple product areas with minimal oversight.
• Have helped establish quality metrics (escaped defects, coverage, release stability) that the team tracks and acts on.
• Be improving QA tooling and practices beyond your own areas.
• Be ready to take on broader scope and mentor newer QA team members.
