Firmware QA Test Engineer

Role: Firmware QA Engineer
Location: Westlake Village, CA (Onsite)
Duration: Longterm

Skills: Firmware Testing, Free RTOS, Zephyr

seeking a Firmware QA Engineer to improve reliability across our IoT-enabled cold chain logistics platform serving healthcare and pharmaceutical customers. This role is firmware-focused and hands-on. You will spend significant time running manual tests on real hardware, reproducing issues, collecting logs, and performing ship testing (pre-deployment verification) to ensure devices behave correctly before they go out to customers.

Responsibilities

• Validate firmware releases on hardware against defined scope and acceptance criteria
• Execute manual regression testing across core device behaviors (power, sensors, charging, connectivity, fault recovery)
• Perform ship testing and pre-deployment verification, including device setup, configuration checks, and release readiness validation for outgoing units
• Run dedicated firmware test passes for each release (smoke, regression, and targeted suites) and report clear pass/fail results
• Validate functionality and firmware behavior, including time to first fix, accuracy checks, signal loss and recovery, and low-signal edge cases
• Reproduce and triage device issues using logs and lab tools (serial logs, in-house tools)
• Partner with firmware and hardware engineers early to clarify expected behavior, edge cases, and testability needs
• Validate connectivity behavior relevant to firmware, including pairing and stability
• Support investigation and reproduction of customer-impacting issues by capturing device evidence and helping isolate root cause boundaries
• Contribute light scripting and tooling to speed up repetitive checks (Python, shell), but automation is not the core requirement
• Communicate quality status, risks, and tradeoffs clearly to cross-functional stakeholders

Requirements and Skills

• Experience testing connected systems such as IoT platforms, distributed services, or cloud-based applications
• Familiarity with embedded firmware validation concepts and hardware integrated testing
• Strong understanding of test design, regression strategies, and risk-based testing
• Experience validating production facing releases and assessing customer impact
• Ability to identify gaps in coverage and communicate quality risk clearly
• Ability to work effectively across engineering, product, operations, and support teams
• Comfortable clarifying scope, asking questions, and pushing back on priorities using data and risk
• Strong written and verbal communication skills
• Pragmatic and outcomes focused, prioritizing impact over activity
• Able to balance execution with continuous improvement while managing competing priorities
