• • Design, build, and maintain high-quality Android software that applies current industry best practices, ensuring the codebase is clean, testable, and ready for rapid iteration while setting the foundation for long-term growth.
• • Deeply understand existing mobile architecture and proactively suggest improvements—whether that’s refactoring legacy flows, adopting new libraries, or championing modern patterns like Server-Driven UI (SDUI)—to keep Quizlet at the cutting edge of mobile learning experiences.
• • Drive incident investigations, post-mortems, and retrospectives; turn every outage or bug into a learning opportunity and effectively advocate for long-term improvements to systems, processes, and team culture.
• • Influence within your team and across adjacent engineering groups to raise the bar on code quality, automated testing, observability, and CI/CD practices, ensuring we ship with confidence and recover quickly when things go wrong.
• • Collaborate closely with cross-functional partners to define requirements, break down complex problems, and deliver solutions that balance immediate customer needs with strategic technical investments.
• • Work onsite in our London office a minimum of three days per week (Monday, Wednesday, Thursday) to foster tight collaboration, rapid feedback loops, and a strong sense of shared ownership among teammates.
• • Contribute to a culture of continuous learning by mentoring junior engineers, sharing knowledge through tech talks and design reviews, and staying curious about emerging Android technologies and cognitive-science-driven learning techniques.
• • Champion accessibility, performance, and internationalization best practices so that Quizlet’s mobile experience is fast, inclusive, and delightful for learners across diverse geographies, devices, and abilities.
• • Leverage our cutting-edge recommendation systems and generative AI capabilities to build adaptive study modes, personalized home navigation, and rich content features that make studying more effective and enjoyable.
• • Instrument features with analytics and observability hooks to measure impact, iterate based on data, and ensure the mobile experience remains reliable as we scale to over 1 billion learning interactions per week.
