Guidance Navigation and Controls (GNC) Engineer III - Project Based

This is a project-based employee role supporting the development, integration, and validation of ASI's autonomous dozer platforms. Development phases of this nature typically continue through project completion, often spanning two to four years, although scope and duration are determined by business and customer needs.

JOB SUMMARY

The Guidance, Navigation, and Controls Engineer III develops, integrates, and validates algorithms that enable ASI's autonomous dozers to navigate work sites, follow planned paths, maintain stable vehicle control, and complete earthmoving tasks accurately and safely. This role works with vehicle dynamics, localization, state estimation, trajectory planning, path tracking, and control systems to support reliable autonomous operation in challenging construction environments. As a Level III engineer within ASI's five-level engineering structure, this position independently contributes to moderately complex GNC features and subsystem improvements while receiving guidance on broader architectural and system-level decisions. The role collaborates with perception, embedded software, systems, test, and field operations teams to improve autonomous dozer performance across uneven terrain, changing soil conditions, slopes, confined work areas, and active construction sites.
