Location: Tbilisi, Georgia; Yerevan, Armenia; Belgrade, Serbia; Almaty, Kazakhstan; Minsk, Belarus; Tashkent, Uzbekistan The Vault is a crypto-finance company building an MPC-based crypto custody and wallet platform designed for both institutional and retail users. Our infrastructure combines threshold signing, HSM and hardware-wallet integration with non-extractable key shares, and robust recovery and policy flows across a growing range of chains and assets. We are headquartered in Limassol, Cyprus. We are looking for a QA Engineer to help us ensure product quality through a combination of manual and automated testing. It is important to us that you use AI tools in your day-to-day work and take an active part in developing our QA processes together with the team. A key focus of this role is intensive automation of our current, largely semi-manual testing process. While manual testing remains part of the job, the clear expectation is that you will steadily replace repetitive manual checks with reliable automated coverage — this is an automation-heavy role, not a predominantly manual one. Responsibilities: • Perform manual functional, regression, integration, and exploratory testing. • Develop and maintain automated tests for UI and API. • Analyse requirements, surface ambiguities, and design test scenarios. • Create and maintain test cases, checklists, and test data. • Report defects clearly, verify fixes, and track issues through to resolution. • Decide which checks are worth automating and integrate automated tests into CI/CD. • Collaborate with developers, designers, and the product team. • Use AI tools to prepare test scenarios, write automated tests, analyse failures, and speed up routine tasks — while verifying the quality of their output. Requirements • Hands-on experience in manual and automated testing of web applications and APIs. • Solid grasp of testing fundamentals, test design techniques, and the software development lifecycle. • Experience with Playwright, Cypress, Selenium, or similar tools. • Programming skills sufficient to write and maintain automated tests. • Ability to produce clear test documentation and reproducible bug reports. • Experience with DevTools, API clients such as Postman, and issue-tracking systems. • Knowledge of Git and an understanding of CI/CD principles. • Confident, regular use of AI tools in QA processes — this is a mandatory requirement. • Ability to critically evaluate AI output and follow the rules for handling confidential data. • Attention to detail, independence, and the ability to make a well-reasoned case for the issues you find. Nice to Have • Experience testing back-office systems, internal admin panels, or enterprise applications with complex business processes. • Experience verifying role models, access permissions, approval workflows, and audit logs. • Knowledge of SQL and experience validating data correctness. • Skills in working with logs and monitoring tools. Benefits Competitive salary; Annual performance bonus; Fully remote position — work from anywhere in the world (team operates on CET); Paid time off, including vacation, sick leave, and public holidays.
