Who we are

Samsara (NYSE: IOT) is the pioneer of the Connected Operations™ Cloud, which is a platform that enables organizations that depend on physical operations to harness Internet of Things (IoT) data to develop actionable insights and improve their operations. At Samsara, we are helping improve the safety, efficiency and sustainability of the physical operations that power our global economy. Representing more than 40% of global GDP, these industries are the infrastructure of our planet, including agriculture, construction, field services, transportation, and manufacturing — and we are excited to help digitally transform their operations at scale.

Working at Samsara means you’ll help define the future of physical operations and be on a team that’s shaping an exciting array of product solutions, including Video-Based Safety, Vehicle Telematics, Apps and Driver Workflows, Equipment Monitoring, and Site Visibility. As part of a recently public company, you’ll have the autonomy and support to make an impact as we build for the long term.

About this 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 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.

You should apply if:

  • You want to impact the industries that run our world: Your efforts will result in real-world impact—helping to keep the lights on, get food into grocery stores, reduce emissions, and most importantly, ensure workers return home safely.
  • You are the architect of your own career: If you put in the work, this role won’t be your last at Samsara. We set up our employees for success and have built a culture that encourages rapid career development, countless opportunities to experiment and master your craft in a hyper growth environment.
  • You’re energized by our opportunity: The vision we have to digitize large sectors of the global economy requires your full focus and best efforts to bring forth creative, ambitious ideas for our customers.
  • You want to be with the best: At Samsara, we win together, celebrate together and support each other. You will be surrounded by a high-caliber team that will encourage you to do your best.
