Hands-On IoT Firmware QA Engineer: Real-Device Testing

Ember LifeSciences; Westlake Village (CA); On-site; USD 110,000 - 140,000; Full time

Job summary

Ember Life Sciences is 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, involving manual tests on real hardware, log collection, and pre-deployment verification.

You will collaborate with firmware and hardware teams, validate releases, run regression tests across device behaviors, and contribute light scripting to speed up checks.

Qualifications

• Experience testing connected systems (IoT platforms, distributed services, or cloud apps).
• Familiarity with embedded firmware validation concepts and hardware-in-the-loop testing.
• Strong test design, regression strategies, and risk-based testing.
• Experience validating production releases and assessing customer impact.

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 for outgoing units.
• Run firmware test passes (smoke, regression, targeted suites) and report pass/fail results.
• Validate GPS functionality and firmware behavior, including TTF, accuracy checks, and edge cases.
• Reproduce and triage device issues using logs and lab tools.
• Partner with firmware and hardware engineers early to clarify behavior and testability needs.
• Validate connectivity behavior relevant to firmware, including pairing and stability.
• Support investigation of customer-impacting issues by capturing device evidence and aiding root-cause analysis.
• Contribute light scripting and tooling (Python, shell) to speed up checks; automation not core.
• Communicate quality status, risks, and tradeoffs clearly to stakeholders.
