About the Role

We're building a no-code creative tool that turns ideas into finished video content — used by everyone from film students to brand marketers to YouTubers cutting their next upload. We need a Senior QA Engineer who can own quality across a product where the bar isn't it doesn't crash, it's it renders exactly what the user pictured. You'll test everything from drag-and-drop editing to export pipelines to the AI-assisted features that are supposed to feel like magic and not like guesswork.

Responsibilities

Design test strategy for the core editor: timeline manipulation, drag-and-drop assets, templates, transitions, text overlays, and real-time preview
Own quality for the render/export pipeline — the place where subtle bugs turn into a ruined final video and a furious user
Test across the absurd range of inputs real users throw at a no-code tool: huge files, tiny files, weird aspect ratios, corrupted uploads, unsupported codecs
Build automated test suites for UI flows and APIs, and set up visual regression testing for anything render-related (a pixel-shifted output is a bug here, not a nitpick)
Test AI-assisted features (auto-captioning, scene suggestions, voice sync, or similar) for correctness and for graceful failure when the model gets it wrong
Validate cross-device and cross-browser behavior — this product needs to work identically whether someone's on a school laptop or a marketing team's workstation
Partner with engineers and designers early, in design review, so quality is part of the spec instead of a gate at the end
Investigate user-reported issues (a why does my video look wrong ticket is rarely simple) and drive root-cause fixes, not workarounds
Define release criteria and hold them, especially before feature launches aimed at creator or education audiences

Qualifications

Fluent English (C1/C2 level) - Able to communicate complex technical concepts smoothly with international clients
5+ years in QA roles, ideally with at least 2 years testing consumer creative, media, or content-editing tools
Strong automation experience (Selenium, Playwright, Cypress, or similar) and comfort writing your own test tooling in Python or JavaScript
Experience testing media pipelines — video/audio encoding, rendering, file format handling, or similar — is a major plus
Understanding of API testing, CI/CD, and how to build quality gates into a fast product-iteration cycle
An eye for the small visual bug: a frame that's one pixel off, a caption that's a beat out of sync, an export that looks fine at 480p and breaks at 4K
Experience testing products used by non-technical users — you think about confusing UX as a bug category, not just crashes
Clear communication; you'll need to explain to a PM why it mostly works isn't good enough for a creative tool

Nice to Have

Experience with generative AI features (text-to-video, auto-editing, AI voiceover) and how to test something with inherently non-deterministic output
Familiarity with performance/load testing for render-heavy backend systems
Background in EdTech, MarTech, or creator-economy products
