The QA Lead will be one of the key people behind the reliability of our core products: web funnels, paywalls, payments and subscriptions, and integrations. You will shape the test strategy, drive automation, own release readiness, and grow a team of 5 QA engineers. This is a full-time remote position with European working hours, ideal for a hands-on QA leader who enjoys building processes, growing people, and taking ownership of product quality. What You Will Do Team Leadership & Development Lead the Manual and Automation QA teams (5 direct reports): distribute workload, set priorities, and ensure predictable delivery.

Quality Metrics Track and improve QA efficiency, test coverage, and defect trends, and use the data to make decisions. AI-Assisted QA Introduce AI-assisted QA practices where they deliver measurable impact without compromising quality. What We Are Looking For (must-have): QA Leadership Experience: 6+ years of experience as a QA Lead with direct reports in both manual and automation testing: workload distribution, mentoring, feedback, and performance reviews. Your background is in product IT companies. Test Strategy & Release Readiness: You have owned a test strategy end to end: quality gates, regression approach, manual vs. automated balance, and release go/no-go decisions. You apply risk-based testing and work with quality metrics such as production defects, defect leakage, automation coverage, and regression efficiency. Strong Hands-On Technical Depth: You test frontend, backend, APIs, integrations, and E2E flows yourself, and investigate complex issues independently using Chrome DevTools, network analysis, logs, HAR files, and monitoring. You are confident with Postman and Swagger/OpenAPI: authentication, webhooks, retries, error handling, and data consistency. Payments & Subscriptions: You have tested payment and subscription flows: Chargebee, Adapty, Payrails, Apple Pay / Google Pay, taxes, local currencies, and pricing. Automation Architecture Understanding: You understand test automation architecture, CI/CD, flaky tests, and maintenance cost, and have practical familiarity with Playwright/TypeScript or a similar framework. Practical Use of AI: You use AI tools (Claude, Cursor, or similar) in test design, requirements analysis, and documentation, and critically evaluate their output. Communication & Stakeholder Management: You explain quality risks clearly to engineering, product, and leadership, push back when needed, and build quality as a shared engineering responsibility. Nice-to-Have: Hands-on development and maintenance of Playwright/TypeScript automated tests. Experience with funnel platforms, A/B testing, traffic allocation, and experiment analytics. CRM and marketing integrations (Reteno or similar). Testing AI features and non-deterministic systems. Experience introducing AI-assisted QA and measuring its effectiveness. Managing a QA function in a fast-growing product company, ideally B2C mobile subscription or EdTech. Analytics validation, complex UI flows, responsive design, and cross-browser testing; experience with TestRail, Jira, and Confluence. Why You'll Love Working With Us: Real impact: You will own quality for the platform behind our web funnels, paywalls, and payments. Your work will directly affect revenue and release speed, and you will see firsthand how quality and delivery improve thanks to your efforts. Flexibility: 100% remote work. Our team is globally distributed across Europe and beyond. Health: company-provided medical expense compensation. AI solutions: AI subscription and other tools. Balance: Flexible paid time off, you get 21 days of annual leave + 10 bank holidays. Collaborative Culture: Work alongside passionate professionals who are as driven as you are.

Location: Europe; Canada Workplace: hybrid 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. ABOUT US Xsolla is a global commerce company with robust tools and services designed to help developers solve the inherent challenges of the video game industry. From indie to AAA studios, companies partner with Xsolla to help them fund, distribute, market, and monetize their games. Grounded in a strong belief in the future of video games, Xsolla is resolute in its mission to bring opportunities together and continually make new resources available to creators. Headquartered and incorporated in Los Angeles, California, Xsolla operates as a merchant of record and has helped more than 1,500 game developers reach more players and grow their businesses worldwide. With more paths to profit and ways to win, developers have everything they need to enjoy the game. For more information, visit xsolla.com . WHAT YOU WILL WORK ON A consumer smart wallet built on account abstraction, so players can own and use digital items without managing keys or gas themselves. Integrations with an external wallet-infrastructure partner and with Xsolla's existing player products. Taking the wallet from testnet to a production launch on an Ethereum-compatible Layer 2. RESPONSIBILITIES Own the end-to-end test strategy for the wallet: sign-in, wallet creation, asset display, send and receive, and transaction confirmation on Xsolla ZK . Test account-abstraction flows: UserOperation construction and validation, bundler submission, EntryPoint execution, paymaster-sponsored gas, and session-key and signer behaviour. Test signing end to end: personal_sign and EIP-712 typed-data requests through the EIP-1193 provider, and signature validation by the wallet contract (ERC-1271), including before the wallet is deployed. Verify counterfactual deployment: that the address derived with CREATE2 from the factory, salt and init code matches the deployed wallet contract, on a forked or local chain, before it reaches mainnet. Deploy, call and inspect smart contracts from the command line to set up test state and reproduce defects. Use chain-forking and simulation tools to test against real network state without real funds, and trace failed transactions to their root cause. Validate the full transaction lifecycle — broadcast, inclusion, reorgs and finality — and its failure paths: reverts, failed UserOperations, insufficient balance, expired session keys, ownership changing mid-flight, and bundler errors. Reconcile what players see with on-chain state: indexer balances and NFT ownership against contract state, including when the indexer lags or diverges, and the account-to-wallet records behind Xsolla ID. Test transfers and approvals across ERC-20, ERC-721 and ERC-1155, including partial ERC-1155 quantities and safe transfers into contract wallets. Write acceptance tests for a partner's wallet SDK and contracts, and report integration defects with the evidence needed to route them to the right owner. Build and maintain automation: Playwright for wallet UI flows, and scripted on-chain checks in TypeScript that run in CI. Set up and maintain AI tooling in the test repositories (Claude Code, Codex, Cursor: rules, context, harness) so QA and engineers use it effectively. Plan and run testnet-to-mainnet release validation, including contract deployment verification and post-deploy smoke checks. Work with security on signing, key handling and key-export flows, and test for signature replay, typed-data phishing and token approval abuse. Mentor QA engineers who are new to Web3, and raise on-chain testing practice across teams. QUALIFICATIONS Required experience Bachelor's degree in Computer Science, Software Engineering, Information Systems or a related field (or international equivalent). 6+ years in software testing or quality engineering, including 2+ years of hands-on testing on EVM -based products. Web3 libraries and tooling Hands-on work with viem and wagmi (ethers.js also counts): reading contract state, sending transactions, and decoding events and revert errors from test code. Deploying and interacting with smart contracts from the command line with Foundry (forge, cast, anvil) or Hardhat; able to read Solidity well enough to know what a contract is meant to do. Chain forking and simulation with Anvil, Tenderly or similar tools, and tracing a failed transaction from a block explorer or transaction trace down to its revert reason. On-chain fundamentals A working model of Ethereum transactions: nonces, gas, receipts, events and logs, reverts, reorgs and finality — including the gap between a sequencer confirmation and L1 finality on a rollup — and how indexers can lag or diverge from chain state. Token standards: ERC-20, ERC-721 and ERC-1155 mechanics, including approvals and the safe-transfer callbacks a contract wallet must implement to receive NFTs. How wallet signers work: EOAs, embedded wallets and smart accounts; personal_sign (EIP-191) and typed data (EIP-712); the EIP-1193 provider; signature validation for contract accounts (ERC-1271). Practical understanding of account abstraction (ERC-4337): UserOperations, bundlers, the EntryPoint, paymasters, counterfactual deployment and CREATE2 address derivation, and session keys. Wallet security basics: signature replay and cross-chain replay, phishing via typed-data signing, and token approval abuse — and how to design test cases that catch them. Testing and automation Test automation in TypeScript or JavaScript, and UI automation with Playwright or a similar framework. API testing over REST and JSON- RPC , including bundler methods (eth_sendUserOperation, eth_estimateUserOperationGas, eth_getUserOperationReceipt), and basic SQL. Daily hands-on use of AI coding tools (Claude Code, Codex, Cursor) for test design, automation and review — generating test cases from specs, analysing logs and transaction traces — including configuring them for a repository. Ways of working Able to run complex, high-impact testing with minimal supervision and wide latitude for independent judgment. Excellent written and spoken English, and proven collaboration in cross-functional teams across time zones. Preferred Experience on a wallet, decentralized exchange or NFT marketplace. ZK Stack and zk -rollups: native account abstraction and paymaster flows on zkSync-family chains, and how finality, gas and EVM compatibility differ from Ethereum mainnet. Embedded, MPC or white-label wallet SDK integrations. EIP-7702 delegation, and ERC-6492 signature validation for accounts that are not yet deployed. Writing on-chain tests in Foundry, including fuzz and invariant tests; familiarity with OpenZeppelin contracts and the ERC-4337 reference implementation. Consumer-scale or gaming products. Reading Go. Load and performance testing of high-volume transaction flows, for example with k6. BENEFITS We are passionate about fostering a supportive environment for our team, so we prioritize the physical, mental, and emotional well-being of our employees and their families through a comprehensive Benefits Program. This includes medical, dental, and vision, PTO , and a personalized career roadmap for each employee. By investing in professional development through training and educational opportunities, we ensure that our team thrives both personally and professionally.
