[Hiring] Quality Engineer - Safety Firmware @Samsara

Role Description

Samsara's Firmware Quality Engineering (FWQE) team ensures that the firmware powering millions of Physical AI–enabled IoT devices is robust, reliable, and customer-ready. Our devices run perception and ML workloads at the edge and feed the Connected Operations Cloud — and the firmware underneath has to be rock solid in trucks crossing deserts, on construction sites, and in cold-chain warehouses.

We're looking for a Firmware Quality Engineer to plan, automate, and execute validation for MCU-based embedded firmware running on RTOS that powers our Physical AI devices in the field. You'll work hands-on across test planning, automation, system validation, and CI, partnering with firmware, hardware, AI/ML, and product teams to improve coverage, signal, and release confidence for devices deployed in demanding industrial environments with complex connectivity (cellular, GPS, BLE, Wi-Fi, CAN).

This is a remote position open to candidates residing in the US & Canada.

Qualifications

• 3+ years of professional experience in embedded systems, firmware validation, or closely related hardware–software integration testing.
• Hands-on experience testing RTOS-based embedded software (FreeRTOS, Zephyr, or equivalent), including familiarity with common debug interfaces, logging, and on-target instrumentation.
• Proficiency in Python (or a similar language) for test automation, tooling, and log/data analysis.
• Experience with Git and CI/CD systems (Jenkins, Buildkite, GitHub Actions, or equivalent), including integrating automated tests into pipelines and triaging flakes from real failures.
• Hands-on experience building with AI — for example, integrating LLMs into test automation, developer tooling, or log analysis; validating ML-powered features; or shipping internal tools that leverage AI APIs.
• Strong written communication and organization across test plans, bug reports, runbooks, and cross-team handoffs.
• Ability to drive well-defined projects independently while escalating ambiguity and cross-team blockers appropriately.

Requirements

• Experience with wireless stacks and/or vehicle/industrial buses (e.g. BLE, Wi‑Fi, cellular, GPS, CAN).
• Exposure to HIL, device farms, or protocol analyzers / bus tools.
• Familiarity with metrics for quality (defect density, escape analysis, flaky-test tracking) and driving incremental improvements.
• Comfort operating in Linux environments and command-line workflows for devices and automation.

Benefits

• Flexible working model that caters to the diverse needs of our teams.
• Professional development stipend.
• Comprehensive health and parental leave plans.
• Above-market total compensation through a combination of base salary, performance-based bonus/variable pay, and equity (for eligible roles).
