Proof of work 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.

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.

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
