Senior QA Engineer (Remote)

About the role

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

Required Qualifications

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

Preferred Experience

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
