Job Description
Senior QA Engineer
Location: Austin, TX (Hybrid – three days per week in office)
Employment Type: Full-time
Company: Black Unicorn US, Inc.
About Black Unicorn
Black Unicorn is a technology-driven family office headquartered in the Cayman Islands, with its engineering hub in Austin. We pair private capital with in-house product and engineering teams to launch platforms in payments, financial infrastructure, e-commerce, and media. We invest and operate across several countries and industries, and we move with conviction to create enduring, high growth companies.
The Role
We’re hiring a Senior QA Engineer to test our websites, mobile apps, web applications, e-commerce journeys, and banking/payment products. In a typical week, you might test an ACH payment, an e-commerce checkout, a mobile release, and the APIs underneath them. When customers move money through our platforms, you’re the one who makes sure it’s right before we ship.
This is an opportunity to build QA from the ground up. You’ll be involved from the first requirements conversation through to production, working closely with engineering, product, and design, and using AI tools to write test cases, generate test data, and speed up defect analysis.
This role is based in Austin, TX, and requires three days a week in our downtown office.
What You'll Do
- Create and execute test plans, test cases, checklists, and regression suites.
- Review requirements and designs early, and flag gaps, edge cases, and testability issues before development starts.
- Own quality in our PCI and SOC 2 compliant stack, with particular focus on detecting and preventing any PCI data exposure across our web apps.
- Test web, mobile, cloud, e-commerce, banking, payment, and API workflows.
- Test payment and money-movement flows end to end, including ACH transfers, card payments, refunds, reversals, failed and duplicate transactions, and ledger and reconciliation accuracy.
- Test customer onboarding and identity verification (KYC), login and authentication, roles and permissions, and how the apps handle sensitive data.
- Test APIs and third-party integrations with Postman or similar tools, including error handling, timeouts, and data validation.
- Identify, document, track, retest, and verify defects.
- Validate releases across browsers, devices, operating systems, and environments.
- Collaborate with product managers, designers, engineers, and operations teams to ensure release quality.
- Support performance and load testing and help improve overall QA coverage and processes.
- Track and report on quality, including defect trends, test coverage, and release readiness, so leadership can make clear go/no-go decisions.
What you bring
- 10+ years of software testing experience.
- 5+ years testing banking, payment, or transaction-based applications.
- 2+ years of fintech experience.
- Proven manual testing experience across mobile, web, APIs, and cloud-hosted applications.
- Ability to test APIs using Postman or similar tools.
- Experience testing e-commerce, checkout, payment processing, authentication, refunds, transaction errors, and related user journeys.
- Experience with functional, regression, exploratory, integration, and user acceptance testing.
- Experience with performance or load testing. Strong defect reporting, test-case writing, and release-validation skills.
- Familiarity with issue-tracking tools such as Monday.com, Azure, and DevOps.
Compensation and Benefits
We offer a competitive salary and strong benefits, including comprehensive medical, dental, and vision coverage and 401(k) matching.
