Quality Assurance Automation Engineer

This is a fully remote position, open to applicants in United States.

📋 Description

• You will take charge of quality and test automation at Cashen.

• Your responsibility will include constructing the QA infrastructure from the ground up — encompassing automated test suites, CI integration, regression coverage, and release validation — for a platform where bugs can have financial repercussions.

• You will collaborate closely with the CTO and the development team to ensure that every release meets the stringent correctness standards required for institutional financial software.

• As the platform evolves from an off-chain marketplace to on-chain DAML smart contracts, you will expand test coverage across both layers.

⛳️ Requirements

• 3–5 years of experience in QA engineering or test automation, with a focus on building test infrastructure — not merely executing manual test plans.

• Proficiency in TypeScript and JavaScript is essential — the backend utilizes NestJS, the frontend employs React, and your testing tools must integrate with both.

• Familiarity with API testing, integration testing, and end-to-end testing frameworks (such as Playwright, Cypress, Jest, or similar).

• A background in fintech, financial services, or any system where numerical accuracy and state machine correctness are critical.

• Experience with CI/CD pipelines is necessary — you will integrate automated tests into the deployment workflow.

• Ability to read and reason about financial logic: interest calculations, LTV thresholds, settlement sequences, and multi-party deal flows.

• You will create the automated test suite from scratch, ensuring integration and end-to-end coverage for backend APIs and frontend applications.

• Design test frameworks to validate financial logic — focusing on interest accrual precision, state machine transition completeness, and margin call trigger accuracy.

• Integrate automated tests into CI/CD pipelines to ensure every pull request and deployment is validated prior to reaching production.

• Build and manage test data fixtures and environment configurations for consistent, isolated test execution.

• You will oversee the release validation process — defining what it means to be "release-ready" and ensuring compliance.

• Work alongside engineers during development to identify gaps in testability and advocate for architectures that facilitate testing.

• Expand test coverage to include DAML smart contracts and on-chain/off-chain integration as the platform transitions to Canton.

• Document test plans, coverage maps, and known gaps to maintain team visibility into quality posture at all times.

🏝️ Benefits

• Build from the ground up: You will design the entire QA infrastructure for an institutional financial platform.

• Real financial implications: Your efforts will directly safeguard institutional counterparties from erroneous deal execution.

• Canton ecosystem: Supported by Ergonia and Cumberland, with direct access to the Canton Foundation and ecosystem partners.

• A lean team with high impact in a fast-paced environment: Every test you develop protects real capital. Quality is a priority here.
