About the Team:
The Engineering Excellence Team is for engineers who build the systems that power everything else. No product tickets. No UI tweaks. No support loops. You’ll create the tools, standards, and frameworks that make every development team faster and stronger.
This is deep technical work with massive impact - shaping architecture, unifying processes, and defining how engineering is done across the company. A place for senior engineers who want to build the backbone, not the features. This is not a product team. It’s a technical excellence engine for people who want to build the systems behind the systems - and elevate the whole company through world‑class engineering.
