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 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.

An ideal candidate also has:

• 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.
