Principal Engineer - Applications

Job description

Weave is a leading all-in-one customer experience and payments software platform for small and medium-sized healthcare businesses (SMBs).

Your success will be measured not by your personal output, but by how the organization's technical capability grows through your influence, mentorship, and strategic leadership. This role requires someone with impeccable technical judgment, the ability to operate in ambiguity, and the character to lead through influence rather than authority. You'll be a visible leader whose approach to problem-solving becomes the template for how engineering operates at Weave. The Applications Fellowship encompasses multiple engineering teams responsible for building and scaling our user-facing products: Payments, Scheduling, Forms, Business Experience, Mobile Apps, and Revenue Cycle Management (RCM).
