Principal Engineer

Weave is a leading all-in-one customer experience and payments software platform for small and medium-sized healthcare businesses (SMBs). We are seeking a Principal Engineer to serve as a technical cornerstone of our Applications Fellowship—the domain responsible for key patient-facing and practice-facing features, including RCM Experiences (Payments and Insurance Verification), Scheduling, Forms, Team Chat, Task Center, and Mobile App features for 40,000+ healthcare practices. This is not a role for someone seeking a larger individual contributor scope; it's a role for someone who shapes technical strategy at the company level, influences architectural decisions across multiple teams, and solves the hardest problems that span organizational boundaries. As a Principal Engineer, you will own the multi-year technical vision for the applications domain, including core systems for Payments and Scheduling, ensuring architectural decisions position Weave for long-term competitive advantage. You'll partner with Engineering Directors, Staff Engineers, and Product leadership to ensure our technical decisions position Weave for long-term competitive advantage. 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). You will work across these teams as a technical leader, partnering with Engineering Managers, Staff Engineers, and cross-functional stakeholders to drive architectural coherence and strategic technical initiatives. • This position is hybrid (Lehi, UT) or Remote (US-based). • Reports to: Sr Director of Engineering WHAT YOU WILL OWN Technical Strategy & Architecture - Own the multi-year technical vision for Payments, Scheduling, Forms, Business Experience and RCM application platforms, ensuring architectural decisions position Weave for scale, reliability, and competitive advantage - Drive architectural coherence across multiple teams, identifying and resolving cross-system dependencies and technical debt at the platform level - Lead technical due diligence for major initiatives, including build-vs-buy decisions, vendor evaluations, and platform migrations Cross-Team Problem Solving - Identify and solve company-level technical problems that span organizational boundaries—the problems that are too complex, too cross-cutting, or too ambiguous for any single team to own - Compile information across systems, teams, and projects to develop comprehensive solutions with extensive validation, rollback, and testing plans - Forecast project costs in time, money, and opportunity cost; account for impacts across the business Strategic Technical Leadership - Monitor the industry landscape, anticipate where high-scale customer experience and transactional platforms are heading, and ensure Weave stays ahead of the curve - Cut through noise and hype to identify genuine strategic value; advocate for and lead key initiatives that prepare Weave for emerging challenges - Shape company-wide standards for engineering excellence, observability, and reliability in distributed systems Mentorship & Organizational Capability - Actively mentor Staff and Senior Engineers across the fellowship, developing the next generation of technical leaders - Elevate architectural thinking across teams through design reviews, documentation standards, and hands-on guidance - Build organizational capability that persists beyond your individual…
