About Cardano Foundation

The Cardano Foundation is an independent, Swiss-based not-for-profit organization. The Foundation is tasked with advancing the public digital infrastructure Cardano and works to anchor it as a utility for financial and social systems, thus empowering the digital architects of the future. The Foundation facilitates the worldwide advancement of Cardano in enterprise applications. It develops infrastructure tooling—including where there may not be an immediate commercial use case—plus strengthens operational resilience, and drives diversity of on-infrastructure use cases as well as the development of sound and representative governance.

About the Role

We are looking for an SDET to join a small, high impact team. You will shape quality from the ground up across everything we ship: the Veridian Wallet, enterprise credential management applications, cloud based backend services and open source protocol libraries. Our stack builds on the open protocols KERI and ACDC using components such as KERIA (Python), Signify-TS and Signify-Java.

You will wear multiple hats, in a highly complex domain. Some weeks that means writing test automation frameworks. Other weeks it means jumping into CI/CD pipelines, debugging a flaky mobile build, reviewing security sensitive code or helping define acceptance criteria for a feature that did not exist last month.

Responsibilities

• Design and implement end to end, integration and API test automation frameworks.
• Build CI/CD quality gates that catch regressions before they merge.
• Obsess over edge cases: revoked keys, out of order events, race conditions.
• Test across Veridian's full product stack: wallet, services, libraries.
• Collaborate with frontend and backend engineers to improve testability.
• Own test environments, test data management and reporting.

Requirements

• 3+ years in an SDET or test automation role.
• Strong hands-on experience developing production grade automation frameworks in languages like TypeScript and Java.
• Familiar with mobile testing (Appium, Maestro or similar).
• Background in security sensitive systems (key management, cryptographic operations).
• Exposure to fault tolerant domains (out of order messaging, connectivity failures).
• Comfort with CI/CD pipelines (GitHub Actions preferred), containers (Docker) and lifecycle tooling (Git, Jira/Confluence).
• Self motivated, independent and thorough in finding what others miss.

Nice to Have

• Fluency with AI tools to write tests more efficiently, generate edge cases and expand coverage.
• Industry experience in cryptography and key management.
• Familiarity with decentralized identity protocols and systems.
• Performance and load testing experience.
• Experience in a startup environment where speed, ownership and adaptability matter more than process.

Benefits

• Enjoy the benefits of remote work with the flexibility to tailor your hours that best supports your productivity, while staying aligned with the team.
• Collaborative remote environment where ideas flow freely and everyone feels empowered to contribute.
• Annual learning budget to invest in your professional journey.
• Opportunities for growth and continuous evolution of your skills and expertise within a supportive environment.
• Your work will directly contribute to the development and adoption of Cardano, shaping the future of blockchain technology and its real-world applications.
• Dedicated annual team building event, as well as a departmental team-building day.
• Extra day off for your birthday and additional days off to celebrate milestone work anniversaries.
• Work with a team of dedicated individuals who are driven by a shared passion for blockchain technology and its potential to change the world.
