Founding Engineer
About The Position
Our client is an early-stage AI startup building a proactive personal assistant that automates workflows across email, calendar, meetings, and other productivity tools. Their vision is to create an AI system that can act on behalf of users, handling tasks, managing workflows, and continuously learning from interactions—similar to what coding copilots have done for developers, but for all knowledge workers. The company has already raised $7.8M from top-tier investors including Kleiner Perkins and has paying customers at companies like Avoca, Rho, xAI, and Brex. With a small, high-caliber team (including backgrounds from MIT, Scale, and Jane Street), they are now hiring early engineers to help build foundational systems and define the product.
