QA Engineer

• 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).

All zerohash employees are guided by the following characteristics and core principles:

• Independence/Ownership - An ability to work autonomously. Join zerohash, pitch ideas, and shape the work you do.

• Passion - We are innovating quickly and challenging the status quo. We want you to think big, be creative and ​make a difference every day.

• Collaborative - A good attitude and respect for others. We’re teammates, not co-workers. Everything we do is a shared success and equally a shared failure - we talk in terms of “we” not “me”.

• Initiative - An ability and passion for learning and asking questions. We will champion you, challenge you and push you to achieve your best - and we expect you to do the same.

• Empathy - An ability to listen, respect, and understand your co-workers, customers, and everyone you interact with no matter how different they are to you.

• Adaptability - An ability to respond quickly. We are in a fast-paced industry and so we expect you to be creative when solving a new problem and comfortable under pressure.

• Transparency - We believe that transparency is critical to empowering everyone to make the best decisions, both the company to its people and vice versa.

• Integrity - Integrity creates trust. As both an organization collectively and as individuals, it is our most valuable asset.
