What you'll do:
Mobile is central to how NinjaTrader reaches the next generation of retail traders. Our Flutter-based platform runs on iOS and Android, and the bar for quality is high — traders make real financial decisions on it. As a Sr. Software Engineer in Test on the Mobile team, you will own automation and quality for our mobile applications, working as a peer to Flutter engineers and product managers. You will shape how our apps are built to be testable, not just verify what ships.
In this role you will:
- Architect, build, and maintain a scalable end-to-end mobile automation framework for our Flutter-based iOS and Android applications
- Lead automation efforts across both platforms, with a focus on long-term framework stability and coverage
- 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
What you'll need:
- 7+ years of experience in QA engineering and test automation, with significant mobile automation experience
- Proven experience building and scaling mobile E2E automation frameworks for iOS and Android
- Strong hands-on experience with Appium, WebdriverIO, or comparable mobile automation tools
- Demonstrated experience working with mobile engineers on testability-by-design
- Deep understanding of Screen/Page Object Model or equivalent patterns for mobile test architecture
- Strong proficiency in TypeScript or JavaScript
- Experience with CI/CD tooling for mobile delivery, including GitHub Actions
- Experience designing test strategies that integrate into automated pipelines at scale
- Proven proficiency with AI-assisted engineering tools applied responsibly in a mobile QA context
- Track record of improving automation stability and reducing flakiness
- Strong communication and collaboration skills — comfortable as a peer to Flutter engineers and product managers
Bonus points for:
- Hands-on experience with Flutter-native testing tools (flutter_test, integration_test package)
- Familiarity with iOS and Android internals, simulators, and emulators
- Experience with cloud device labs (e.g., Sauce Labs, BrowserStack, or similar)
- API automation testing experience
- Accessibility testing awareness (WCAG or mobile platform standards)
- Financial trading systems or fintech experience
Compensation:
