The code you write will reach millions and help define the firm. We're seeking engineers across the stack who thrive in a client-driven, agile environment: individuals who are confident building high-performance, resilient solutions with a passion for delivering superior user experiences. You'll work with modern technologies including React Native, Flutter, Relay, RESTful web services, and OAuth 2.0 — and use them to build cutting-edge software with advanced data visualizations.

Architect, design, and implement new features and functionalities across existing mobile applications. Build low-latency SDKs and highly scalable APIs to support our growing analytics platform. Optimize mobile applications for performance, usability, and reliability. Conduct code reviews, identify and resolve bugs, and continuously raise the bar on code quality. Collaborate with product managers, designers, and backend engineers to understand requirements and deliver robust mobile solutions. Guide and mentor team members toward a clear technical vision. Stay current with the latest trends in mobile development and champion innovative solutions.
