QA/SDET Engineer (Nearshore)

Overview

We're looking for a Nearshore Senior QA Engineer to own quality across a modern full-stack lending platform. This isn't a checkbox QA role — you're embedded in the squad, shifting left, catching issues early, and building the test infrastructure that lets the team ship with confidence. Real ownership from day one on a high-visibility engagement.

Key Responsibilities

• Test Strategy & Ownership

• Own the end-to-end QA strategy across the full-stack platform — frontend (Next.js), backend (C#/.NET), and integrations
• Design, build, and maintain automated test suites covering functional, regression, integration, and E2E scenarios
• Define and enforce quality gates across the CI/CD pipeline — nothing ships without passing the bar you set

• Integration & API Testing

• Lead QA coverage across critical third-party integrations — credit bureaus (Experian, Equifax, TransUnion), dealer systems (DealerTrack, RouteOne), fraud and verification providers
• Validate REST API contracts, retry logic, idempotency, and edge case handling
• Test DEFI Solutions loan origination workflows — scorecards, rules, decision flows, and operational data

• Collaboration & Process

• 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
• Partner with the Tech Lead to align QA practices with overall engineering standards
• Serve as the quality voice in the room — advocate for the end user and the integrity of the platform
• Bridge between nearshore squad and US-based stakeholders — strong English communication required

• Tooling & Automation

• Build and maintain automation frameworks using modern QA tooling (Playwright, Cypress, Selenium, or similar)
• Leverage AI-assisted testing tools to accelerate coverage and reduce manual effort
• Own test environments, test data management, and QA documentation

Must-Haves

• 5+ years of QA engineering experience in a fast-paced, agile environment

• Strong automation experience — Playwright, Cypress, or equivalent

• API testing proficiency — Postman, REST Assured, or similar

• Experience testing complex integrations and third-party vendor systems

• SQL proficiency — ability to validate data at the database level (PostgreSQL, SQL Server)

• AWS familiarity — understanding of cloud-based environments and containerized deployments

• Strong English communication for daily standups and US stakeholder collaboration

Nice-to-Haves

• Experience testing Loan Origination Systems — DEFI Solutions or equivalent

• Auto finance, lending, or regulated-industry background

• Performance and load testing experience

• Experience with CI/CD pipelines — GitHub Actions, Jenkins, or similar

• AI-assisted testing tooling experience

Logistics

• Fully remote — no travel required

• Standups at 9:30am CST — Mexico timezone friendly

• Possible team offsite every 6 months (Phoenix or East/West Coast)

• Mexico-based role — no visa or work authorization requirements
