Senior C++ Engineer — Build Core System Remotely

Echo is building a new product team and seeks the first core engineer to shape the system from the ground up, becoming its backbone and setting the quality bar from day one. This is not a generic developer role—it's an opportunity to influence architecture, drive technical decisions, and own outcomes.

You’ll build a C++ system from scratch (C++17/20), tackle multithreading and memory management, and help define scalable patterns and tooling for the team.
