QA Engineer

• You’ll join zerohash’s growing QA function, working alongside engineers and SDETs

• As a QA Engineer, you’ll own test planning, functional and exploratory testing, and user acceptance testing (UAT) across zerohash’s product stack

• This is an opportunity to shape testing practices and quality standards as the team scales, with visibility into every product area and a direct line to release quality

• Test coverage: Design, document, and execute functional and exploratory test cases for API- and SDK-based product flows

• Automation testing: 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

• Cross-functional planning: Partner with product managers, developers, and SDETs to translate acceptance criteria into concrete test scenarios, and proactively call out coverage gaps and edge cases

• Release quality: Own regression testing for your assigned area ahead of each release, and support the team’s release-readiness process

• UAT: Help formalize and run User Acceptance Testing across product and engineering as zerohash standardizes this process company-wide

• Defect management: Log, triage, and track defects with clear repro steps, severity, and expected-vs-actual detail; follow issues through to resolution

• Automation collaboration: Flag coverage gaps that need deeper automated testing and route them to developers, who own unit and integration test automation

• Environments: Test across dev, cert, and prod environments, and participate in release readiness reviews

Benefits

• Excellent healthcare + dental + vision coverage. Zero Hash covers roughly 100% of employee premiums

• 33 Days Flexible PTO

• Equity ownership

• WFH setup

• Learning & Development Stipend

• Mental health and wellness program- Experience using Jira and Confluence, or equivalent tools, for test planning, tracking, and documentation

• Clear, detailed written communication: bug reports and test plans that others can act on without back-and-forth

• Comfortable writing and maintaining automated tests (e.g., Playwright, Selenium) for occasional ad hoc work and automation tech debt

• Comfortable collaborating across time zones with a distributed engineering team

• Experience with BDD-style test scenario writing (Gherkin/Cucumber or similar)

• Working knowledge of SQL for data verification and familiarity with Git-based workflows (GitHub)

• Comfortable working in a fast-paced environment, switching between competing priorities and projects

• Proficiency in at least one programming or scripting language used for test automation (e.g., JavaScript/TypeScript or Python)

• 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 a test management or UAT tool (e.g., TestRail, Zephyr, or similar)

• 5+ years of QA or test engineering experience, ideally in fintech, payments, or another regulated, API-driven environment

• 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)
