About the role

Senior Embedded Software Engineer role at Samsara focused on firmware for resource-constrained, battery-powered IoT devices and Linux-based gateways. You will bring up new hardware platforms, develop embedded software across MCU and gateway layers, and mentor others while aligning hardware choices with customer and business outcomes.

Responsibilities

  • Shape the hardware, not just the code that runs on it. Sit in reviews with electrical engineers and argue for the right SoC, flash/RAM, and sensor combinations, then validate on prototypes reaching customers in months.
  • 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, core management layers like power and connectivity.
  • Chase every microamp. Design protocols and hardware management for battery-powered sensors and gateways with long device life.
  • Work with the people who ship the whole product. Partner with product, full-stack, mobile and quality engineers to ensure data integrity from firmware to end use.
  • Raise the bar for the engineers around you. Lead by example, strengthen engineering practices, and deliver high-quality solutions iteratively.

Qualifications

  • 8+ years building firmware for resource-constrained systems
  • Led firmware development for several new products end to end
  • Substantial bare-metal and RTOS experience (Zephyr, FreeRTOS, or equivalent)
  • Bringing up new boards (first power-on of unproven hardware)
  • Fluency in low-level interfaces - SPI, I2C, UART, CAN, ADC
  • Strong bench and test mindset (oscilloscope, network analyzer, RF spectrum analyzer)
  • Senior-level scope across hardware, firmware, cloud and quality
  • Cross-layer judgment from driver level to customer impact
  • Fluency in C
  • Ability to write design docs, reviews, and post-mortems
  • Ship fast with quality and automated testing
  • Ability to leverage AI in workflow
