Jobs

Mastra is seeking a Founding Sales AE to be the second dedicated sales hire, joining a rapidly growing team closing multiple deals weekly. This full-cycle, mid-market role involves selling Mastra's open-source TypeScript-native AI agent framework and commercial products to Series A-C companies, often with regulatory or infra constraints. The ideal candidate will be a product-obsessed, customer-obsessed, and insanely driven individual with a founder mentality, comfortable with ambiguity and a fast-evolving product landscape. You'll start with a warm pipeline, focusing on running and improving the sales motion, engaging with engineering leaders, and closing deals for a company backed by Y Combinator and Spark Capital.
