Nearshore Senior QA Engineer

Must-Haves

• 5+ years of QA engineering experience in a fast-paced, agile environment
• Strong automation experience — Playwright or Cypress
• NUnit experience — building and maintaining automated test suites
• API testing proficiency — Postman, REST Assured, or similar
• Experience testing complex integrations and third-party vendor systems
• SQL proficiency — ability to query and validate data at the database level (PostgreSQL or SQL Server)
• Cloud familiarity — AWS or Azure, plus containerized deployments (doesn't need to be deep)
• AI-assisted development experience — hands-on with both Claude and GitHub Copilot
• Strong understanding of software testing methodologies and QA best practices
• Ability to collaborate closely with engineers, product managers, and business stakeholders
• Strong analytical and troubleshooting skills

Key Responsibilities

Test Strategy & Ownership

• 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

Integration, API & Data 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
• 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

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

Tooling & Automation

• Build and execute UI and web automation using Playwright or Cypress
• Develop and maintain automated test suites using NUnit
• Leverage AI-assisted development tools — Claude and GitHub Copilot — to accelerate coverage, test case generation, and analysis
• Own the automation stack end-to-end, from framework design to CI/CD integration

What we offer

• Full-time payroll position
• Benefits as stated by Mexican law
• SGMM
• Life insurance
• Grocery vouchers
• Savings fund

Nice-to-Haves

• Experience building an automation framework from the ground up
• 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
• Experience with Selenium or another browser automation framework, in addition to Playwright/Cypress

We're looking for a Nearshore Senior QA Engineer to own quality across a modern full-stack lending platform — and to own the automation framework it runs on. 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. This is an automation-first seat: if you've only maintained someone else's test scripts, this probably isn't the right fit.

The platform includes a Next.js frontend, C#/.NET backend services, REST APIs, PostgreSQL and SQL Server data environments, and a network of third-party lending integrations.
