What are we hiring for?

The systems that run millions of businesses.

Every month, 2.6 billion messages flow through our platform. Our automation engine enrolls 3.1 billion contacts and executes 21.5 billion workflow actions in the same window — with API traffic peaking at 28,000+ requests per second. Booking appointments, closing deals, answering customers. If these systems lag, businesses lose leads. If they go down, people lose income.

We're hiring backend engineers who treat that as a design constraint, not a fun fact.

This isn't a role where you'll implement someone else's spec. You'll be handed problems that don't have a known answer yet — a datastore buckling under index growth, a queue that needs to absorb 10x burst traffic without dropping a message, a state machine with millions of concurrent executions. You'll figure it out. And you'll own it.


Team & System Overview:
The Conversations organization powers multi-channel communication across SMS, Email, WhatsApp, and DMs — handling over 2B messages each month. The Threads & Composer team owns the inbox and composer surfaces, and the backend services that deliver and store those interactions.You’ll work across Node.js microservices, GCP-based infra (GKE, Pub/Sub, Cloud Tasks), and MongoDB/Firestore storage layers, ensuring every message and UI state stays consistent, fast, and recoverable.
