Your opportunity

Make a real difference in the blockchain industry! Build the change you want to see.

Veridian is building the infrastructure layer for digital identity. Born as a Cardano Foundation initiative, our technology already powers credential issuance and verification across regulated industries.

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. In this role you will:

• 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.

Your story

• 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.

Your impact

• Ensure the reliability and security of identity systems used by governments and enterprises.
• Build lean, automated pipelines that let a small team ship fast without compromising quality.
• Define quality standards that become the team’s standards.

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.
