Own QA strategy and execution for a crypto payments product squad. Build and maintain automated UI, API, and backend tests using TypeScript and Playwright, integrate regression testing into CI/CD, and conduct exploratory, acceptance, and release testing. Review requirements, manage the automation backlog, communicate product issues, maintain QA reports, and drive quality decisions with engineering, product, stakeholders, and vendors.
Role Overview
As a Senior QA Engineer, you will be responsible for quality in a new product squad working in US hours on a crypto payment platform. The role is automation-first: you write and maintain automated tests on top of a shared test framework, move routine regression into CI, and complement automation with hands-on exploratory and acceptance testing for client-facing releases. Success means the squad ships client-facing functionality confidently.
Key Responsibilities- Own the test strategy and execution for the squad: acceptance, exploratory, and regression testing
- Write and maintain automated UI and API tests on the shared test framework
- Own and prioritize the automation backlog; move routine regression into CI so releases are not blocked on manual passes
- Review product requirements and acceptance criteria with product and engineering, providing feedback before development starts
- Verify client-facing releases and run acceptance testing before they reach clients
- Communicate with stakeholders and third-party vendors about ongoing product issues
- Maintain QA documentation and reports, including release testing and escaped defects reports
- 5+ years of experience as a QA Engineer on web applications
- Strong experience writing and maintaining automated test scripts for UI, API, or backend tests
- Good programming skills in TypeScript
- Proficiency in a modern automation framework, i.e. Playwright
- Experience integrating automated tests into CI/CD pipelines
- Hands-on manual testing skills: exploratory, regression, smoke, and acceptance testing
- Hands-on experience with API testing tools such as Insomnia or Postman
- Proficiency in writing SQL queries for testing and data verification
- Understanding of the test pyramid and automation strategy
- Proficient use of AI tooling in test design and coding, with critical review of AI-generated output
- Prior crypto experience is optional; building a working understanding of crypto and stablecoin payment flows on the job is a mandatory part of the role
- High agency: you raise quality risks while they are still cheap to fix and drive them to a decision
- Strong written and verbal communication in English
- Fintech, payments, or crypto domain experience
- Experience with Jira and TestRail (or similar products)
- Experience configuring CI/CD pipelines (e.g. GitLab CI)
- Experience with Agile/Scrum methodologies and shift-left practices
- Performance testing experience
