You know what the compiler is doing, and you can read a linker map, a stack trace, or a corrupted heap without guessing. * Solid 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 helped bring 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 your code, a library, the schematic, or the part itself. * Fluency in the low-level interfaces - SPI, I2C, UART, CAN, ADC and the ability to debug the seam between hardware and software. * Real bench instincts. The usage of an oscilloscope, network analyzer, or RF spectrum analyzer, is how you form a hypothesis, not what you reach for after the print statements run out. * Cross-team scope. You have contributed to work spanning hardware, firmware, cloud and quality from concept to shipped product. You have worked effectively across teams to build consensus. * Cross-layer judgment. You can trace how a decision at the driver level surfaces in a customer's experience three layers up, and you factor that into your design decisions. * You write things down. Design docs, review comments and post-mortems that other engineers can actually act on. * You ship fast without shipping poorly. Comfortable iterating on customer feedback at speed, backed by automated testing and code you would be content to inherit. * You use AI smartly. It's part of your every day work flow and multiplies your output without watering things down. ## Description * Shape the hardware, not just the code that runs on it. Sit in reviews with our electrical engineers and help choose 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. * Build 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. * Raise the bar for the engineers around you. Your designs, reviews, and instincts help 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., * BLE at depth - You understand what's going on down the PHY and can build orchestration for the system to use in a performant and power efficient way. * Cellular IoT - LTE-M or NB-IoT modem integration, power state management, and the certification gauntlet (FCC, PTCRB, carrier approval). * Securing embedded systems end to end - secure boot, firmware signing, cryptography, and key management that survives contact with manufacturing. * OTA and device firmware update at fleet scale - A/B partitions, rollback, and the discipline of never bricking a device you cannot physically reach. * Embedded Linux on the gateway side - Yocto or Buildroot, kernel drivers, device trees. * CAN and J1939 work on commercial vehicles, including reverse-engineering data bus parameters across makes and models. * Python and Bash for tooling, and hardware-in-the-loop test automation. * You've been on the factory floor - You have an understanding of the processes behind the mass production and quality assurance of electronics. You have a track record of fixing production show stoppers. Total Rewards At Samsara, we build for the people who keep the global economy moving. We want owners, not passengers, which is why our rewards are designed to fuel high-impact builders. Our compensation program delivers above-market total compensation through a combination of base salary, performance-based bonus/variable pay, and equity (for eligible roles) in a high-growth public company. We meaningfully differentiate pay for our top performers, who have the opportunity to earn above-market compensation that can outpace the broader market over time. Beyond compensation, we provide the foundations that enable long-term success: a flexible, employee-led remote model, a professional development stipend, comprehensive health and parental leave plans, and more. If you're ready to build for the long term and own the outcome, your journey starts here.
