Software Engineer - Hardware Interfaces

About the Role:

At Rapid Flow Technologies, we want our Surtrac traffic control software to be compatible with every traffic controller, detection system, and communications system in the world. Our hardware interface team is dedicated to this mission, and this role will be one of the first full-time members of this team. As such, an ideal Interface Engineer is able to tackle hardware interface design and testing, as well as lead development and identify areas of work for future interface engineers.

Interfaces include those for traffic controllers, video detection, in-ground loops, radar, and other detection, within varying network configurations. For new interfaces, you will design fault-tolerant methods that maximize information flow while safeguarding against device and network malfunctions. For existing interfaces, you will create rigorous lab and in-field testing and define known areas of performance across network configurations. Additionally, you will work with the RapidView team to bolster our monitoring and alert system for issues that arise in real-world traffic deployments, and also to support on-device deployment automation tools.

This role is crucial to the expansion of the Surtrac network, as we move quickly toward new products that depend on network growth.


  • Be the lead hardware interface design engineer for Surtrac and future products.
  • Design fault-tolerant interfaces for traffic hardware, with varying communications protocols.
  • Design rigorous testing and analysis for device and interface performance. - Interact with vendors/hardware companies to track down issues with their communications protocols.
  • Be the primary interface with the RapidView team to develop alerts and notifications for tracking hardware issues in real time.
