Role
Who you are
- Strong experience with test automation in JavaScript/TypeScript or Python

- Hands-on experience with browser-based E2E testing frameworks such as Playwright or Cypress
- Practical experience automating Web3 workflows, including:
- Transaction signing, approvals, nonce handling, and failure scenarios
- Network switching, RPC configuration, and chain-specific behavior
- Experience working with CI/CD systems and running automated tests in containerized environments
- Strong QA fundamentals: bug reporting, exploratory testing, risk-based testing, and test documentation
- A detail-oriented, skeptical mindset with a passion for breaking complex systems to make them robust
- We encourage you to apply for roles where you don't fully meet the listed requirements, especially if you're passionate or knowledgable about crypto!
Desirable
- Wallet extensions and programmatic wallet control (e.g. Synpress, custom MetaMask automation)
- Solid understanding of blockchain fundamentals (EVM and beyond): transactions, gas, events/logs, confirmations, reorgs
- Familiarity with tools such as Hardhat, Foundry, or Anvil for local blockchain testing
- Experience validating financial workflows, balances, and reconciliation logic
- Understanding of security, custody, and wallet safety considerations
- Personal or professional experience using crypto wallets, DeFi protocols, or trading platforms
What the job involves
- We are seeking an experienced Senior QA Automation Engineer to join our platform team, focused on ensuring the quality, reliability, and security of our Web3 and backend systems
- The team builds and operates core infrastructure and user-facing applications that interact with blockchains, smart contracts, wallets, and off-chain services. Our goal is to deliver highly reliable, production-grade financial products in a fast-moving and highly regulated environment
- This role focuses on designing, building, and maintaining automated test systems across backend services, smart-contract–adjacent flows, and Web3-enabled user interfaces. We are looking for someone with an extreme eye for detail, strong systems thinking, and a pragmatic “ship fast, but don’t ship broken” mindset
- Design, implement, and maintain automated test suites covering backend services, APIs, and event-driven systems
- Build and own end-to-end test automation for Web3 user flows, including wallet interactions, signing flows, approvals, and transaction lifecycle validation
- Automate browser-based UI tests involving wallet extensions (e.g. MetaMask) using tools such as Synpress, Playwright, or Cypress
- Validate blockchain-related workflows including deposits, withdrawals, mint/burn flows, bridges, and on-chain/off-chain reconciliation
- Collaborate closely with backend, frontend, blockchain, and DevOps engineers to embed testing deeply into the SDLC
- Integrate test automation into CI/CD pipelines with clear reporting, fast feedback, and high signal-to-noise
- Proactively identify edge cases, race conditions, and failure modes specific to distributed systems and blockchain environments
- Document test strategies, known risks, and quality gates, and help define release readiness criteria
Our take
Kraken is one of the world's leading and longest-standing cryptocurrency exchanges, known for its focus on transparency and security. The platform offers trading across a wide range of digital assets and fiat currencies, including USD, EUR, and CAD, and serves millions of users globally. Consistently rated as one of the most trusted and secure exchanges in the industry, Kraken has built a reputation on reliability, users protection, and a commitment to its proof-of-reserves verification that allows clients to independently confirm their holdings.
Kraken allows users to trade and invest in spot and derivatives markets, as well as participate in staking, custody, and tokenized asset products. It was also among the first exchanges to undergo a cryptographically verifiable proof-of-reserves audit and continues to lead with innovations such as tokenized US stocks ("xStocks") for non-US customers and expanded institutional services. Alongside this, the company's offerings are designed to make digital finance more accessible and complaint while supporting traders, investors, and enterprises navigating the fast-evolving crypto landscape.
On top of this success, Kraken reported a standout performance in the third quarter of 2025 - doubling its revenue year-on-year to $648M and boosting quarterly profit margins to nearly 28%. Trading volumes climbed to $562B, while assets on the platform rose to $59B, emphasizing the exchange's growth and strong customer confidence. Having expanded its product suite, strengthened its institutional reach, and invested in governance and compliance, Kraken is now in a position for continued expansion (and, potentially, a future public listing), as one of the most resilient and respected names in the global crypto market.
