You own quality and test automation at Cashen. You will build the QA infrastructure from the ground up — automated test suites, CI integration, regression coverage, and release validation — for a platform where bugs have financial consequences. A missed edge case in a deal state transition or an interest accrual rounding error doesn’t just degrade UX — it moves money incorrectly between institutional counterparties.

You work directly with the CTO and the development team to ensure that every release meets the correctness bar required for institutional financial software. As the platform expands from off-chain marketplace to on-chain DAML smart contracts, you will extend test coverage across both layers.

Requirements

Who We’re Looking For

• 3–5 years in QA engineering or test automation, with experience building test infrastructure — not just running manual test plans

• Strong TypeScript and JavaScript proficiency — the backend is NestJS, the frontend is React, and your test tooling must integrate with both

• Experience with API testing, integration testing, and end-to-end test frameworks (Playwright, Cypress, Jest, or equivalent)

• Background in fintech, financial services, or any system where numerical precision and state machine correctness matter

• Familiarity with CI/CD pipelines — you will wire automated tests into the deployment process

• Comfortable reading and reasoning about financial logic: interest calculations, LTV thresholds, settlement sequences, and multi-party deal flows

Test Infrastructure & Automation

• Build the automated test suite from scratch: integration and end-to-end coverage across backend APIs and frontend application

• Design test frameworks for financial logic validation — interest accrual precision, state machine transition completeness, margin call trigger accuracy

• Integrate automated tests into CI/CD pipelines so that every pull request and deployment is validated before reaching production

• Build and maintain test data fixtures and environment management for repeatable, isolated test execution

Release Quality & Collaboration

• Own the release validation process — define what “release-ready” means and enforce it

• Collaborate with engineers during development to identify testability gaps and advocate for testable architecture

• Extend test coverage to DAML smart contracts and on-chain/off-chain integration as the platform moves to Canton

• Document test plans, coverage maps, and known gaps so the team has visibility into quality posture at all times

Benefits

Why Cashen

• Build from zero: You design the entire QA infrastructure for an institutional financial platform

• Real financial stakes: Your work directly protects institutional counterparties from incorrect deal execution

• Canton ecosystem: Backed by Ergonia and Cumberland, with direct access to Canton Foundation and ecosystem partners

• Lean team, high leverage, fast-paced: Every test you write guards real capital. Quality is not an afterthought here

About Cashen

Cashen is the institutional deal execution layer on Canton Network, backed by Ergonia. We connect whitelisted institutional counterparties for collateralized crypto lending and CC locking arrangements using a tri-party custody model. Cashen operates as a ministerial agent — we never hold assets or take principal risk. We have an operational mainnet validator, a live off-chain marketplace, and active counterparty relationships with institutional participants.
