QA Engineer (Manual & Automated Testing)

The Vault is looking for a QA Engineer to help ensure the quality of our MPC-based crypto custody and wallet platform for institutional and retail users. This role is mostly about automation. Much of our testing is still semi-manual today, and you will steadily replace repetitive checks with reliable automated UI and API tests built into CI/CD. Manual functional, regression and exploratory testing stays part of the job. You’ll work closely with developers, designers and product, and use AI tools every day to write test scenarios and tests and to analyse failures. We’re looking for someone with hands-on experience in manual and automated testing of web apps and APIs, using Playwright, Cypress, Selenium or similar tools, and with enough programming skill to maintain the tests. Confident daily use of AI tools in QA is a must. Experience testing back-office or admin systems, role models and approval workflows, or SQL is a plus.
