Extracted from the posting
Senior QA Engineer owning test strategy for Xsolla's smart wallet on Xsolla ZK, an Ethereum-compatible ZK rollup, including account abstraction, signing, and counterfactual deployment.

ABOUT YOU
We are looking for a Senior QA Engineer who has tested real on-chain products — the contracts and the transactions, not only the web app in front of them. You will own quality for Xsolla's smart wallet on Xsolla ZK, our Ethereum-compatible ZK rollup: the wallet players use to hold, receive and send tokens and in-game items, signing in with the account they already have.
The work runs on both sides of the chain. On the backend, you will confirm that a wallet address pre-computed from a salt is the address that actually gets deployed. On the frontend, you will follow a signed operation from the client's RPC call through the bundler to finality, and prove it landed, failed or reverted the way it should. You will fork the chain to test against real state, deploy and call contracts from the command line, and turn what you learn into automated suites.
You will work in a small, senior engineering team alongside an external wallet-infrastructure partner. You can tell a defect in our code from one in a partner SDK or in the chain itself — and you bring the evidence to show which. AI coding tools are part of how you work every day, and you set them up so the rest of the team gets the same leverage.
