About Us:

Hi Auto is revolutionizing the restaurant industry with an advanced virtual assistant powered by conversational AI.

Our cutting-edge voice-based technology is already making waves in Quick Service Restaurants (QSRs), streamlining automated order-taking. By enhancing customer interactions, boosting revenue, and alleviating staff workload, our AI is redefining efficiency in the food service sector.

Our team consists of skilled professionals specializing in backend development and conversational AI. We tackle complex challenges using innovative, state-of-the-art solutions. We value impact-driven work, offering a remote-friendly environment where productivity and comfort go hand in hand. With a fast-paced atmosphere and diverse challenges, team members gain significant professional growth and a sense of ownership over their work.

Role Overview:

Our backend infrastructure is entirely Python-based, operating in a cloud-native Kubernetes (k8s) environment. Unlike traditional backends focused on UI interactions, our system processes real-time audio streams and powers core AI-driven functionalities.

Seamless integration with various third-party services is a key component of our architecture, demanding reliable and well-structured implementation.

This role requires designing and developing sophisticated backend components, focusing on distributed architecture, concurrency management, and high-performance scaling.
