QA Engineer - Manual & Automated Testing
About the role
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.
