Mobile SDET / Automation Engineer

ProphetX is a prediction market focused on sports, aiming to power America’s next great asset class through sports event contracts. They are seeking a Mobile SDET to own and scale mobile automation efforts across iOS and Android, designing and maintaining a robust automated testing foundation for their mobile platform.

Responsibilities:

• Own the mobile automation framework end-to-end, with Appium and Java as the core stack
• Design and implement automated test suites for iOS and Android covering critical user flows, regression scenarios, and new feature coverage
• Execute and manage automated test runs on real device farms (e.g., BrowserStack, Sauce Labs, AWS Device Farm) as well as local device setups
• Integrate mobile automation into the CI/CD pipeline to enable automated execution on builds and releases
• Maintain and improve framework reliability, including handling flakiness, device-specific issues, and OS version compatibility
• Collaborate with the manual mobile QA engineer to identify automation candidates and expand coverage strategically
• Work closely with iOS and Android engineers to stay ahead of upcoming changes and ensure test coverage keeps pace with development
• Partner with Vietnam-based QA and engineering teams to maintain consistency across the automation strategy
• Analyze and report on automation results, triaging failures and communicating clearly with engineering teams

Requirements:

• Strong, hands-on experience with Appium for mobile test automation on both iOS and Android
• Proficiency in Java as the primary automation language
• Proven experience running automated mobile tests on real device farms (e.g., BrowserStack, Sauce Labs, AWS Device Farm, or similar)
• Experience setting up and managing local device testing environments
• Solid understanding of mobile-specific automation challenges: device fragmentation, OS version differences, flakiness, and app lifecycle management
• Experience integrating mobile automation into CI/CD pipelines (e.g., Jenkins, GitHub Actions, Bitrise, or similar)
• Ability to design maintainable, scalable test frameworks using best practices such as Page Object Model or similar patterns
• Direct QA or automation experience in the betting, gambling, sportsbook, or betting exchange domain is required
• Strong understanding of betting concepts such as markets, odds, events, and settlements
• Experience validating user wallet, balance, and financial transaction flows through automation
• Familiarity with risk-sensitive and revenue-impacting user flows that demand high test confidence
• Exposure to compliance-driven or regulated environments is a plus, especially US-facing products
• Practical experience using AI tools (e.g., ChatGPT, Copilot) to accelerate test design, code generation, or failure analysis
• Interest in or experience with AI-powered mobile testing tools, such as self-healing test frameworks or smart selector strategies
• Genuine drive to use AI to improve automation efficiency, coverage quality, and debugging speed
• Experience with Playwright or other web automation frameworks — useful as our web automation stack also runs on Playwright
• Familiarity with TypeScript or Python in a QA or automation context
• Experience working with distributed engineering teams across time zones
• Background in fintech or real-money transaction testing
