Kill Legacy Code: Gracefully sunset legacy networking components without interrupting the user experience for hundreds of millions of clients.
🎯 Who You Are
An Expert in C++: You have 5+ years of infrastructure or mobile engineering experience, with a heavy focus on production-grade C++.
A Mobile Native: You can effortlessly navigate large, multi-platform codebases (Android/iOS) and know how to ship robust SDKs.
A Networking Nerd: Deep knowledge of HTTP/2+, WebSockets, retries/backoff, and handling offline resilience is second nature to you.
A Technical Leader: You love setting engineering norms, conducting design reviews, and guiding a newly forming team toward architectural excellence.
