Why Join Chief AI

Build AI for decision-makers: you’ll be able to point to real leaders – mayors, congressmen, CEOs – and know your work helped power offices that impact millions
Own the intelligence layer from day one: not just prompts, but the systems that turn messy executive context into reasoning, briefings, and decisions
True founding ownership: ship end-to-end, work directly with customers, and help define the technical DNA of the company

The Role

We’re hiring a Founding Engineer to build the AI-native operating system for modern leadership. You’ll work directly with the CEO and founding team to ship features, design core systems, and solve real-world problems for high-stakes teams.

Within weeks:

Ship core agentic workflows that executive teams rely on day-to-day
Use ingestion and structuring of data to create actionable context
Work directly with customers to understand how their offices operate and where Chief can embed in their daily workflows

Within months:

Help shape Chief’s core architecture and AI workflows for executive reasoning and decision-making
Build upon personalization and intelligence used across briefings, tasks, and relationships
Prototype and iterate with voice-to-text, surfacing recommendations, and more
