About the role
- Sr. Software Test Engineer responsible for automation and quality of mobile apps at NinjaTrader. Leading mobile testing efforts on Flutter-based iOS and Android platforms.
Responsibilities

- Implement and enhance mobile automation using Appium, WebdriverIO, or similar automation frameworks
- Design and enforce a Screen/Page Object Model architecture and project structure that scales with the mobile team
- Write maintainable automation code in TypeScript/JavaScript, establishing standards others build on
- Partner with Flutter engineers on application architecture to identify testability gaps and make automation-friendly design decisions early — before they become late-stage problems
- Own CI/CD integration for mobile test pipelines: tagging strategies (e.g., smoke, regression), automated reporting, and pipeline reliability
- Identify, analyze, and eliminate test flakiness — treating automation reliability as a product quality concern
- Apply AI-assisted development tools — code generation, test generation, failure analysis — to improve coverage and productivity
- Drive improvement in mobile testing tooling and documentation
- Contribute to junior QA team members' growth through code reviews, pairing, and direct feedback
- Uphold NinjaTrader SDLC and information security standards
Requirements
- 7+ years of experience in QA engineering and test automation, with significant mobile automation experience
