The team
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.
The opportunity
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
Skills you should HODL
Strong experience with test automation in JavaScript/TypeScript or Python
Proven experience testing backend systems: REST/GraphQL APIs, async workflows, message queues, and database state validation
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
Nice to haves
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
