Weave is seeking a Principal Engineer to serve as the technical cornerstone of our Messaging Fellowship—the domain responsible for how 30,000+ healthcare practices communicate with their patients across SMS, MMS, email, fax, and emerging channels. 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 messaging infrastructure that processes hundreds of millions of messages and manages terabytes of data. 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 Messaging Fellowship encompasses multiple engineering teams responsible for Weave's core communication capabilities—appointment reminders, review requests, missed-call texts, two-way messaging, and the infrastructure that delivers billions of messages reliably at scale. 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: Director of Engineering
Technical Strategy & Architecture
Own the multi-year technical vision for messaging infrastructure, 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 messaging and data infrastructure 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 contributions
12+ years of software engineering experience with progressive technical leadership scope
Track record of leading cross-team technical initiatives that delivered measurable business outcomes
Demonstrated ability to influence without authority, build consensus across organizational boundaries, and translate technical tradeoffs into business terms
Deep expertise in distributed systems architecture, including building and operating services that handle hundreds of millions of transactions and terabytes of data
Proven experience with event streaming and messaging infrastructure (Kafka, Google Pub/Sub, or similar) at significant scale
Strong background in scalable data stores—both relational (PostgreSQL at scale, Vitess, Spanner) and NoSQL (Bigtable, Redis, etc.)
Operational experience with cloud-native infrastructure on GCP or AWS, including Kubernetes, infrastructure-as-code, and highly available system design
Solid backend engineering foundation (Go preferred; Python, Java, or C# acceptable)
Experience with messaging delivery systems, carrier/aggregator integrations, or telecommunications infrastructure
Expertise in data platform architecture: streaming pipelines, data lakes, warehouses, or distributed analytics
Background in compliance-heavy environments (healthcare, fintech) with experience navigating regulatory requirements in technical design
Experience shaping AI/ML infrastructure or integrating AI capabilities into production systems
History of external technical leadership: open source contributions, conference speaking, or published technical writing
Strong opinions, loosely held—you bring conviction to technical discussions while remaining genuinely open to better ideas
