Senior Quality Engineer

Lipdub AI is revolutionizing AI-powered lip-syncing and voice generation, creating hyper-realistic, seamless audio-visual experiences. We leverage cutting-edge machine learning, deep learning, and real-time inference to bring next-gen media technology to life.

We are looking for a Senior Quality Engineer who is passionate about building rigorous, scalable, and automation-first testing practices that ensure the reliability of our AI-driven media applications.

You will collaborate with developers, ML engineers, and product teams to rigorously test state-of-the-art models for real-time video lip-sync, dubbing, and personalization applications.

• Take full ownership of QA processes: analyze requirements early to build comprehensive test scenarios, covering edge cases in video realism, sync accuracy, and AI outputs.

• Set and enforce testing standards, manage test data creation/maintenance (synthetic videos, multilingual datasets), and automate extensively (pytest/Selenium/CI/CD pipelines) to minimize manual effort.

• Lead release gates by signing off on new features after rigorous validation, root-cause analysis, and collaboration with devs/ML teams for rapid fixes.

• 5+ years QA leadership in SaaS/AI, with proven automation (80%+ coverage) and test data management expertise.

• Strong analytical skills for proactive scenario design from ambiguous specs; Python scripting and tools like JIRA/BrowserStack essential.
