Senior Software Engineer
Envoy AI
Freight brokerages run on people making calls, chasing updates, and jumping between a dozen tools. We're building Agents that help conduct day to day operations end to end.
Our Agent Ellie makes carrier calls, books loads, verifies credentials, sends check-ins, and chases documents. We're live with freight brokers and 3PLs moving real shipments today. The technical challenge: orchestrating thousands of concurrent voice conversations, executing complex workflows in real-time, and integrating with systems built decades before APIs existed.
We're looking for high agency full-stack engineers who are excited about owning problems end-to-end and building systems that power AI-native logistics operations. You'll work alongside our CTO and founding engineers, playing a critical role in scaling our platform from seed stage to supporting hundreds of customers and thousands of concurrent AI agents.
In this role you'll have the opportunity to meaningfully contribute across our entire stack while ensuring our systems are reliable, performant, and cost-effective as we scale. If you've been part of a journey from 10 to 1000 customers, or from prototype to production-grade systems, we want to hear from you.
