Quality Engineer - Safety Firmware

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, and Equipment Monitoring. 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 the role: 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. You should apply if: You want to impact the industries that run our world: Your efforts will result in real-world impact — helping keep the lights on, get food into grocery stores, reduce emissions, and most importantly, ensure workers return home safely. You're excited about Physical AI in the wild: You want to validate AI that lives on devices, not in a data center — where sensors are dirty, networks are flaky, batteries drain, and "ship it" means tens of millions of units in the field. 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 and 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'll be surrounded by a high-caliber team that will encourage you to do your best. In this role, you will:  Test design & execution: Develop and run test plans, manual and automated scenarios, and system-level validation for embedded firmware powering Physical AI devices across one or more product areas. Automation: Implement and maintain automated tests and supporting tooling (Python scripts, frameworks, lab harnesses) to reduce manual effort and increase repeatability across firmware and edge AI feature validation. Collaboration: Partner with firmware developers, hardware engineers, AI/ML engineers, and PMs to clarify requirements, close gaps in coverage, and drive issues to resolution with clear repro steps and evidence. CI & quality signals: Contribute to test infrastructure and CI/CD integration (test jobs, artifacts, dashboards, coverage and pass-rate reporting) to shorten feedback loops for developers. HIL / lab / simulation: Help build, extend, and stabilize HIL setups, device fixtures, and simulation or mocking — including scenario-based testing for AI-driven and perception-dependent behaviors — to improve coverage of hardware-dependent functionality. Shift-left: Participate in design and testability reviews, call out risks early, and improve testability (logging, hooks, configs, model telemetry) where feasible. Field support: Support field validation, log capture and analysis, and triage for customer- or deployment-like issues, working with senior engineers on root-cause and verification. Culture: Role-model customer obsession, high standards, ownership, and collaboration; seek feedback and continuously improve how we test. Champion, role model, and embed Samsara’s cultural principles (Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team) as we scale globally and across new offices Minimum requirements for the role: 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. Comfort using AI coding assistants (Claude Code, Cursor, Copilot, etc.) as part of your daily workflow. Strong written communication and org
