Every year, we partner with our customers to deliver outcomes like conserving millions of gallons of fuel, saving millions of dollars, and creating positive environmental change. As more customers connect to our platform, our data grows, our AI models get smarter, and our opportunities expand.

About the role:

Samsara’s cloud-connected sensor platform collects observations about the world in near real-time. Samsara builds an extensive set of products, including battery-powered, wireless sensors, linux-based IoT gateways, and Internet-connected dashcams. These devices are the building blocks Samsara uses to construct enterprise solutions for a wide range of verticals, including commercial fleet management and industrial monitoring. Through a unique integration of sensor data such as GPS, acceleration, temperature, video, and more, we enable our customers to gain greater insights into operations, identify and eliminate inefficiencies, and react to alerts all in near real-time.

As a senior/staff embedded software engineer at Samsara, you will develop software that runs on millions of devices, deployed by our industrial and enterprise customers. You’ll tackle challenges including evaluating and selecting hardware components, bringing up new hardware platforms and sensors, building systems to gather data and detect meaningful events, and structuring recorded data to allow efficient analysis across thousands of devices while providing deep insights into individual events.

We use C for our MCU based platforms, Golang for embedded applications on linux-based gateways and backend services, Google protocol buffers to structure data, and various AWS technologies to process and store data. Experience with these exact technologies is not required.

This role is hybrid based out of our SF office.
