About The Position

We are seeking a Firmware Validation Test Engineer with 8+ years of experience in a hands-on validation/QA engineering role on firmware or embedded products. The ideal candidate will have demonstrated experience writing and executing test plans/cases, identifying and closing coverage gaps, and managing defects through the full lifecycle. This role requires hands-on validation experience in at least one connectivity domain (Bluetooth, Wi-Fi, cellular, GNSS, or vehicle networking), strong log triage and debugging instincts using tools like Wireshark, DLT, and ADB, and a track record of reproducing and isolating defects reported from production/field environments. Proficiency in Python scripting for automation and log parsing, comfort with Linux/Ubuntu, and strong defect-tracking discipline in JIRA/Confluence within agile release cycles are essential.

Requirements

• 8+ years in a hands-on validation/QA engineering role on firmware or embedded products.
• Demonstrated experience writing and executing test plans/cases, identifying and closing coverage gaps, and managing defects through the full lifecycle.
• Hands-on validation experience in at least one connectivity domain — Bluetooth, Wi-Fi, cellular (LTE/5G), GNSS, or vehicle networking.
• Strong log triage and debugging instincts; comfortable with Wireshark, DLT, ADB, and similar tooling.
• Track record of reproducing and isolating defects reported from production/field environments.
• Python scripting sufficient to automate repetitive checks and parse logs; comfortable on Linux/Ubuntu.
• Strong defect-tracking discipline (JIRA/Confluence) and experience in agile release cycles.

Nice To Haves

• Prior experience with in-cabin entertainment and/or media casting frameworks.
• Bluetooth stack validation (pairing, A2DP/HFP/AVRCP, interop).
• Background and experience in wireless connectivity technologies.
• Prior exposure to autonomous-vehicle or robotaxi fleet environments.

Responsibilities

• Execute functional, integration, regression, and exploratory testing for Audio and streaming features on bench and in-vehicle.
• Author new test cases, expand existing test suites, and keep test documentation current as features evolve.
• Identify untested or under-tested paths in the existing suites and systematically add coverage; track coverage health for each feature track.
• Reproduce defects, capture and analyze logs (Wireshark, DLT, ADB, HCI/Bluetooth traces, vehicle logs), and isolate root cause before handing off to firmware owners.
• Own first-line triage for Audio and Streaming feature fleet issues — reproduce in lab, narrow scope, and drive issues to closure in partnership with fleet support, diagnostics, and firmware teams.
• Manage defects end-to-end in JIRA — clear reproduction steps, attached logs, severity rationale, fix verification, and regression follow-up.
• Maintain test benches, in-vehicle rigs, and diagnostic setups so they stay release-ready.
• Partner with firmware leads, product managers, and integration partners to align on feature readiness and defect priority.
