At Hayden AI, we are on a mission to harness the power of computer vision to transform the way transit systems and other government agencies address real-world challenges.
From bus lane and bus stop enforcement to transportation optimization technologies and beyond, our innovative mobile perception system empowers our clients to accelerate transit, enhance street safety, and drive toward a sustainable future.
Hayden Portal is the full-stack web application that connects all Hayden products. It’s the central platform used by transit agencies, enforcement partners, operations teams, and customer success to manage fleets, review video data, and ensure compliance. Portal drives Hayden’s core business and is a critical touchpoint for our customers and internal teams alike.
We’re looking for a full-stack Senior Software Engineer to join the Portal team and help build the next generation of Hayden’s mission-critical platform. You’ll work as part of a cross-functional team to deliver scalable, performant, and intuitive systems across the stack—from backend APIs to polished, data-rich UIs. As a senior contributor, you’ll own major features end-to-end, mentor other engineers, and influence technical direction. You’ll thrive if you’re pragmatic, product-minded, and passionate about building high-quality software that makes a real-world impact.
Design, implement, and maintain robust backend services and modern frontend components for Portal.
Collaborate on system architecture and technical decisions across the stack, balancing performance, scalability, and maintainability.
