Proactively discussing integration points and versioning can also minimize friction and help deliver a more robust final product.

What is a Flutter Developer?

Job description

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:

The salary range for this role will be $100,000.00 - $150,000.00 USD. In addition, this position will also receive an annual target bonus of 10%. Bonus pay at NinjaTrader is based on individual performance (50%) as well as company/team performance (50%).

Salary and bonus earnings are only two components of the total compensation package offered by NinjaTrader. NinjaTrader offers a 401K plan through ADP under which the company will match up to 3.5% of employee contributions. Annual paid time off allowance accrues at a rate of 18 days per year (some positions may qualify for more) plus seven paid holidays.

Location:

This role is based in Chicago, IL. We are not open to remote candidates for this role. 

Hybrid:

For Chicago-based employees, we follow a hybrid work schedule: In-office Tuesday through Thursday, with remote work on Mondays and Fridays. In addition to these weekly remote days, we offer:

  • 20 additional flex remote days annually
  • 5 Company Wide Office-Optional weeks tied to major holidays
