About The Position

Our client is seeking a high-caliber, product-minded software engineer to join a small, elite founding team. This role is for an engineer who thrives in early-stage environments, takes extreme ownership, and enjoys building real systems that customers depend on. This is a hands-on individual contributor role. You will work closely with founders, product, and customers to design, build, and scale core platform functionality. If you are looking for a management role, heavy process, or large-team structure, this role will not be a fit.

Ability to operate autonomously while collaborating closely with a small team

Partner cross-functionally with product, operations, and customers to translate real-world problems into scalable solutions
