🏢 About Hayden AI

Hayden AI stands out as a mission-driven company using computer vision to solve real-world urban challenges like transit efficiency and street safety. Unlike generic tech companies, they focus specifically on government and transit agency partnerships to create tangible impact on sustainable urban development. Their work directly improves public transportation systems and community safety through innovative AI solutions.

About This Role

As a Senior Software Engineer on the Portal team, you'll build the central web application that connects all Hayden products, used by transit agencies and internal teams to manage fleets and review video data. This role involves full-stack development from backend APIs to data-rich UIs, with ownership of major features that directly impact Hayden's core business operations. You'll influence technical direction while working on a mission-critical platform that serves as the primary interface for customers managing transit enforcement and optimization.

💡 A Day in the Life

A typical day involves collaborating with cross-functional teams to design and implement features for the Hayden Portal, balancing backend API development in Python/Golang with frontend work in React/TypeScript. You might review video data integration requirements with product managers, mentor junior engineers on best practices, and optimize database queries for the fleet management system used by transit agencies across the country.
