Cumberland Labs is a technology company focused on developing innovative software solutions that enhance operations and user experiences across various industries. They leverage cutting-edge programming technologies to create efficient, scalable applications tailored to the needs of their clients.

📋 Description

• 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. • 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

• 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 • 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 • 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

• 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
