Note: The job is a remote job and is open to candidates in USA. zerohash is a crypto and stablecoin infrastructure platform powering digital financial services. The QA Engineer will own test planning, functional and exploratory testing, UAT, regression testing, defect management, and release quality across API- and SDK-based products, while collaborating with engineers, product managers, and SDETs.

Responsibilities

• Design, document, and execute functional and exploratory test cases for API- and SDK-based product flows
• Pick up automation work on an ad hoc or on-demand basis, addressing automation tech debt and critical-flow gaps, using tooling and frameworks built by SDETs
• Partner with product managers, developers, and SDETs to translate acceptance criteria into concrete test scenarios, and proactively call out coverage gaps and edge cases
• Own regression testing for your assigned area ahead of each release, and support the team's release-readiness process
• Help formalize and run User Acceptance Testing across product and engineering as zerohash standardizes this process company-wide
• Log, triage, and track defects with clear repro steps, severity, and expected-vs-actual detail; follow issues through to resolution
• Flag coverage gaps that need deeper automated testing and route them to developers, who own unit and integration test automation
• Test across dev, cert, and prod environments, and participate in release readiness reviews

Skills

• * 5+ years of QA or test engineering experience, ideally in fintech, payments, or another regulated, API-driven environment
• * Strong grasp of QA process across all phases of the SDLC: test planning, test data setup, execution, defect management, and release sign-off
• * Strong test case design and exploratory testing instincts; comfortable reading API specs and testing REST/JSON APIs directly (e.g., Postman, cURL)
• * Experience with BDD-style test scenario writing (Gherkin/Cucumber or similar)
• * Comfortable writing and maintaining automated tests (e.g., Playwright, Selenium) for occasional ad hoc work and automation tech debt
• * Proficiency in at least one programming or scripting language used for test automation (e.g., JavaScript/TypeScript or Python)
• * Working knowledge of SQL for data verification and familiarity with Git-based workflows (GitHub)
• * Experience using Jira and Confluence, or equivalent tools, for test planning, tracking, and documentation
• * Experience with a test management or UAT tool (e.g., TestRail, Zephyr, or similar)
• * Clear, detailed written communication: bug reports and test plans that others can act on without back-and-forth
• * Comfortable working in a fast-paced environment, switching between competing priorities and projects
• * Comfortable collaborating across time zones with a distributed engineering team
• * Experience testing financial transaction flows: ledgers, settlement, reconciliation, or payments
• * Exposure to CI/CD pipelines and how automated tests fit into them
• * Experience working in an Agile/Scrum environment (sprint planning, backlog grooming)
