Nearshore Senior QA Engineer
Summary
Senior QA engineer owning end-to-end test strategy and automation for a lending platform — building Playwright/Cypress UI suites, NUnit test frameworks, and API/database-level validation for loan origination workflows and third-party integrations (credit bureaus, dealer systems), embedded in a nearshore squad serving US-based stakeholders.
- Own the end-to-end QA strategy across the full-stack platform — frontend (Next.js), backend (C#/.NET), APIs, databases, and integrations
- Design, build, and maintain automated test suites covering functional, regression, integration, and E2E scenarios
- Build or substantially extend automation frameworks — this isn't a "maintain what's already there" seat
- Define and enforce automated quality gates across the CI/CD pipeline — nothing ships without passing the bar you set
- Own test environments, test data management, and QA documentation

- Validate REST API contracts, retry logic, idempotency, and edge case handling
- Query and validate application and integration data at the database level using PostgreSQL or SQL Server
- Test DEFI Solutions loan origination workflows — scorecards, rules, decision flows, and operational data
- Embed directly with engineers and product — participating in sprint planning, story grooming, and design reviews to catch issues before a line of code is written
