We believe the future of our nation’s roadways is automated, safer, more accessible and enables more efficient movement of people and goods. While billions have been invested into developing vehicle technologies – including advanced driver assistance systems (“ADAS”) and autonomous driving solutions – a small fraction has been spent on developing infrastructure to support and enhance roadways. At Cavnue, we are developing and integrating technologies that will power the world’s most technologically advanced roadways (“cavnues”). Our approach is founded in creating a digital model of the roadway that analyzes and optimizes road conditions in real-time, sharing actionable alerts and providing proactive guidance to vehicles and drivers.

Join us in innovating the roads of the future. Cavnue is bridging vehicle technology and road infrastructure to rapidly deliver safer roads today while accelerating the adoption of connected and automated vehicles (CAVs) moving forward. With ongoing deployments in Michigan and Texas, Cavnue is the only company in North America that uses Smart Road technology to improve performance for road operators and deliver a safer, more efficient experience for all road users while preparing for a future with more CAVs. Our mission is to set the new standard for road performance and safety.

• First Line of Defense: Serve as the first line of defense for system issues, including triage, remote troubleshooting, configuration updates, and software resets
• Field Triage and Dispatch: Coordinate field interventions by equipping crews with precise, pre-diagnosed issue reports when physical resolution is required
• Operations Automation: Work within our core operational framework (Proxmox, Kubernetes, Terraform) to manage state-specific configurations. Partnering with our engineering organization, building the specific IaC, tools, and automation scripts
• Field Quality Oversight: Oversee operational readiness of new deployments, ensuring field hardware (e.g., cameras, switches) is fully integrated prior to go-live
• Collaborate cross-functionally with engineering, product, and field teams to continuously improve operational efficiency and system reliability

Requirements

• Experience supporting field operations and issue triage within roadway infrastructure, transportation systems, or similar large-scale physical deployments
• Experience working within Linux environments, container orchestration platforms (e.g., Kubernetes), and virtualization systems (e.g., Proxmox)
• Strong scripting and automation experience (Python, Bash, and/or Go) combined with frontend experience (JavaScript) to build intuitive, lightweight user interfaces for field crews.
• Familiarity with deploying applications to edge devices and IoT hardware environments
• Working knowledge of networking fundamentals (e.g., VLANs, routing, IP configuration) for troubleshooting connectivity issues
• Ability to translate complex system issues into clear, actionable workflows or tickets (e.g., Jira, ServiceNow)
• Strong communication skills with the ability to interface effectively with both technical engineering teams and field-based personnel
• Highly self-directed, with the ability to operate independently while collaborating across distributed teams
