Senior Software Development Engineer in Test (SDET)
Dublin (Hybrid)
FinTech | Payments | SaaS
GTreasury is building a new Payments Engineering team and hiring a Senior SDET to own quality end-to-end — shaping testing strategy, influencing engineers early, and driving quality into how systems are built, not just tested. This is not a checkbox-QA role. It's a hands-on, senior IC position with real ownership and visibility.
What you'll be doing
* Owning and evolving the testing and quality strategy
* Driving shift-left practices alongside engineers and product
* Building and improving automation frameworks and CI/CD pipelines
* Acting as the quality authority for the team (no people management)
Tech snapshot
* C# / .NET experience is required
* Microservices & API-heavy systems
* UI & API automation (Cypress / Playwright; some Selenium)
* CI/CD pipelines (Azure DevOps)
* Cloud: Azure
This role suits you if you:
* Are a Senior SDET / Software Engineer in Test / Quality Engineer
* Have tested and automated systems built in C# / .NET
* Enjoy ownership, technical influence, and working closely with engineers
* Care about quality outcomes, not just test coverage
Experience in payments, fintech, or complex platforms is a plus, but not essential.
If you want real ownership and the chance to shape quality in a product-driven engineering environment, we'd love to hear from you, apply directly or reach out.
