Job description

On behalf of FinTech Client #9, SD Solutions is looking for a talented QA Engineer (Manual & Automation)

SD Solutions is a staffing company operating globally. Contact us to get more details about the benefits we offer.

Responsibilities:

• Test new features by hand, deeply: exploratory testing of long, multi-role flows (pricing, eligibility, documents)
• Build and own automation: Playwright + TypeScript E2E and API tests, running in CI
• Keep the suite trustworthy: hunt down flaky tests, maintain selectors and test data, keep regression fast
• Own the release: run the QA board, test plans and regression, and give the go/no-go before every deploy
• Investigate production issues: use Sentry, Datadog, and PostHog to find the error, the logs, and the user session, reproduce it, and hand developers a ticket they can fix right away

Requirements:

• 3–5 years in QA, with real, recent experience in both manual and automated testing
• Hands‑on test automation with Playwright in TypeScript or JavaScript
• Comfortable with Git and CI (GitHub Actions or similar)
• API testing experience (Postman, pytest or similar) and solid SQL to verify data directly in the database
• A sharp eye for business-logic edge cases: states, roles, calculations, and flows that break halfway
• Understanding of how a financial company works: money flows, compliance, and why one wrong number matters
• Clear test plans, test cases and bug reports that a developer can act on without a follow-up question
• Daily use of AI tools in QA work (Claude Code, Cursor, Copilot or similar) to write tests, generate data and find gaps
• Detail-obsessed, and knows which details matter to the business
• Confident saying “not ready,” and explaining why calmly, with evidence
• Strong team player who works with developers, not against them
• Proven remote work: has tested and shipped for years from a home office, communicates in writing by default, and does not need someone nearby to stay unblocked
• Excellent English, written and live
• Organized, independent, and quick to learn a complex domain

Advantages:

• US mortgage industry experience
• Built QA from scratch: planned how to cover a platform (test strategy, flows, regression scope) and ran it in Jira and Confluence
• Performance testing (k6)
• Security testing basics
• Python
