Preferred / Bonus:

Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management.

What we offer

A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect).Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision.A purpose-driven mission: building software that’s reliable, accessible, and user-centered — making a real difference for people.
