About the role

Weave is seeking a Principal Engineer to shape technical strategy for the Messaging Fellowship, owning the multi-year vision for messaging infrastructure and influencing architectural decisions across teams to handle hundreds of millions of messages and terabytes of data.

Responsibilities

  • 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
  • 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
  • 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

Qualifications

  • 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)
