Joble is looking for a meticulous, technically sharp, and detail-driven QA Engineer to join the team and take full ownership of product reliability for Joble, our AI-powered productivity, voice, and web agent platform. This is a high-impact role for an experienced professional. You will be building test frameworks, breaking complex AI workflows, and directly signing off on live production deployments from day one.

We are looking for someone who understands that QA is not just about finding bugs after the fact, it is about championing user experience, functional reliability, and flawless execution at every stage of the product lifecycle.

As the QA Engineer for Joble, you will manage and execute the quality assurance functions across our web and voice platforms — from manual exploratory testing and regression runs to writing comprehensive test scripts, mapping edge cases, and auditing end-to-end user journeys. You will work closely with the product leads and the development team, ensuring our systems maintain top-tier stability across our international markets. This is a 100% remote role.

• Perform rigorous manual testing, regression testing, and exploratory testing across the Joble web application and core interfaces.
• Deeply test Joble’s AI voice capabilities, automated chat handlers, and web agent workflows to ensure absolute stability, accuracy, and performance under real-world conditions.
• Systematically reproduce, isolate, and document bugs with clear, step-by-step replication logs, technical context, and developer notes.
• Maintain a structured tracking cadence within our project management systems to ensure no identified issue goes unresolved or falls through the cracks.
• Manage the bug tracking pipeline daily, classifying issue severity, identifying affected builds, and driving tickets through to verification.
