The GigaGrid product team is developing a plug-and-play framework for monitoring and controlling the power grid. The GigaGrid framework consists of low-cost edge-computing nodes that can interface with geo-dispersed assets and work autonomously. The smart nodes can work in bandwidth constrained environments, using flexible communication pathways to the GigaGrid backend. The GigaGrid product lines revolve around solutions for grid monitoring, control and automation that can help to optimize grid operations as the adoption of distributed energy resources, such as solar, batteries, and electric vehicles, grows dramatically. The GigaGrid product team consists of engineers who are seeking creative, motivated team members to help them take innovative ideas and turn them into tangible solutions.
