About the company
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.
Responsibilities
- Shape the hardware, not just the code that runs on it. Sit in reviews with our electrical engineers and argue for the right SoC, amount of flash/RAM, and combination of sensors, then prove those choices out on prototypes that reach real customers in months, not years.
- Be the first person to make a new board do anything at all. Bring up new platforms and prototypes from virgin silicon: configure I/O, get SPI, I2C, UART, BLE talking, debug system init, validate the design, and turn unproven hardware into a product.
- Own the layers everything else depends on. Peripheral drivers, secure bootloaders, device firmware updates, as well as the core management layers like power and connectivity, that determine whether a device in the field quietly recovers on its own or becomes an RMA.
- Chase every microamp. Design protocols and hardware management for battery-powered sensors and gateways where the gap between good firmware and great firmware is measured in years of device life.
- Work with the people who ship the whole product. Partner with product, full-stack, mobile and quality engineers so the data your firmware produces arrives intact and useful as it lands in the hands of dispatchers, fleet managers, and technicians who depend on it every shift.
- Set the bar for the engineers around you. At Staff level you are a force multiplier: your designs, reviews, and instincts raise the ceiling for the whole team. You will help shape how Samsara works, keep a high bar, be intellectually honest, work with urgency and deliver iteratively, as we scale globally and across new offices.
Requirements
- 8+ years building firmware for resource-constrained systems, on products that shipped to real customers and then had to survive in the field.
- Fluency in C. You know what the compiler is doing, and you can read a linker map, a stack trace, or a corrupted heap without guessing.
- Substantial bare-metal and RTOS experience - Zephyr, FreeRTOS, or equivalent. You have made scheduling, memory and timing decisions. Mutexes and semaphores are everyday tools for you.
- You have brought up new boards. First power-on of unproven hardware, at the bench with the electrical engineer who drew it up, working out whether the bug is in the schematic or the code.
