Xsolla

Xsolla is a video game commerce company founded in 2005 that handles the payment, billing and storefront side of the business for game developers and publishers. Its products cover global payment acceptance in hundreds of methods and currencies, web shops that sell directly to players outside the mobile app stores, subscription and in-game purchase management, partner networks and player acquisition tools, with the company acting as merchant of record so developers do not carry tax and compliance obligations themselves. Headquartered in Los Angeles, it works with thousands of studios and has grown as publishers look for routes around platform store fees.

ABOUT YOU

We are looking for a Senior QA Engineer with strong Web3 experience to join our engineering team. You are meticulous, technically sharp, and deeply curious about decentralized technologies. You understand the nuances of blockchain interactions, wallet integrations, smart contract behavior, and hybrid on-chain/off-chain systems.

You thrive in fast-paced, agile environments and bring a proactive approach to quality-anticipating risks, validating distributed systems, and ensuring seamless user experiences across Web3-enabled features. You are confident in manual testing, comfortable with API-level validation, and eager to integrate AI-driven testing tools to improve coverage, speed, and defect detection.

If you're excited to shape quality practices for blockchain-enabled products and help define how Web3 experiences should feel for millions of users, we'd love to meet you.
