QA Engineer (Automation + Manual)

Company Overview
At SKALE Labs, we are at the forefront of blockchain innovation, powering the SKALE Network - a high-performance multichain network designed to scale decentralized applications. We are looking for a QA Automation Engineer with strong Python expertise to work on backend automation. In this role, you will balance manual and automated testing (30/70) to ensure the reliability, scalability, and security of our systems. You will design, develop, and maintain a test automation framework that supports multiple complex projects. Our projects involve a variety of external integrations and dependencies, so one of the most critical skills we expect is the ability to identify, clearly formulate, and solve unpredictable problems. This role requires not only writing tests but also building the automation infrastructure: from CI/CD integration to custom libraries and utilities. If you are passionate about quality, automation, and blockchain technology, this is your opportunity to contribute to building the future of decentralized systems!
