Job Description


Nearshore — Senior QA Engineer

Mexico-Based Delivery Squad | Fully Remote

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
