About the Team

You will be joining the Quality Engineering (QE) team as a key contributor within the PSM (Performance, Stability, Monitoring) squad supporting 30M+ monthly active users and growing fast. We operate with a proactive, "shift-left" strategy, ensuring quality is engineered into our product from day one, focusing on the core reliability of our iOS product and cross-platform applications. Expect high technical autonomy, a direct impact on user‑perceived reliability, and close collaboration with mobile, backend, ML, and product teams to lay the technical groundwork for future product excellence.

About the Role

This is the role for you, if you’re excited to work on the things listed below:

• Driving Performance & Stability: Owning the non‑functional testing strategy. You will design and execute critical performance, load, and stress tests for our core iOS app to ensure smooth performance for millions of users.
• Architecting Advanced Automation: Building and expanding our automated test suite across iOS and cross platforms (depending on your strong suit). You will also help drive modern framework migrations and API automation.
• Shift‑Left Leadership: Embedding deeply with the feature squad. You won’t just test code; you will design for testability, create comprehensive test plans, and catch critical architectural risks before a single line of code is deployed.

The skills you will need to be successful in the above:

• 7+ years in Quality Engineering or QA roles, with a track record of stability and technical growth.
• Deep, hands‑on experience writing automated tests using Xcode and XCUITest (Swift), and/or cross‑platform (Cypress/Playwright), API testing.
• Performance Profiling: Expertise in using developer tools like Instruments to identify memory leaks, lag, and performance bottlenecks.
• A Versatile QE Mindset: You are as comfortable writing code for automation as you are executing rigorous manual exploratory testing.
• CI/CD Proficiency: Working knowledge of integrating test suites into pipelines (e.g., GitHub Actions, TeamCity).

Even if you don’t meet all the criteria listed above, we would still love to hear from you! Goodnotes places a lot of value on learning and development and will support your growth if needed.

The Interview Process

What’s in it for you

• Meaningful equity in a profitable tech startup.
• Budget for things like noise‑canceling headphones, setting up your home office, personal development, professional training, and health & wellness.
• Company‑wide annual offsite (we met in Bali in 2024 and Istanbul and Seoul in 2025).
• Flexible working hours and location. We expect this role to work 5 days a week.
