Quality Engineer - Safety Firmware

Samsara is a pioneer of the Connected Operations™ Cloud, enabling organizations to harness IoT data for improved operations. They are seeking a Firmware Quality Engineer to plan, automate, and execute validation for embedded firmware powering Physical AI devices, ensuring reliability and customer readiness in demanding environments.

Responsibilities:

• 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
• 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
• 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
• Contribute to test infrastructure and CI/CD integration (test jobs, artifacts, dashboards, coverage and pass-rate reporting) to shorten feedback loops for developers
• 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
• Participate in design and testability reviews, call out risks early, and improve testability (logging, hooks, configs, model telemetry) where feasible
• Support field validation, log capture and analysis, and triage for customer- or deployment-like issues, working with senior engineers on root-cause and verification
• 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

Requirements:

• 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
• 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
