Principal Engineer

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

What You Will Own

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

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

What You Will Need to Accomplish the Job

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)

What Will Make Us Love You

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
