Job description

Firmware Validation Test Engineer (Client: Amazon Zoox) [Location: Foster City, CA]

Location: Foster City, CA

Key Responsibilities:

• Manual feature validation:Execute functional, integration, regression, and exploratory testing for Audio and streaming features on bench and in-vehicle.
• Test content development:Author new test cases, expand existing test suites, and keep test documentation current as features evolve.
• Coverage gap closure:Identify untested or under-tested paths in the existing suites and systematically add coverage; track coverage health for each feature track.
• Root cause analysis:Reproduce defects, capture and analyze logs (Wireshark, DLT, ADB, HCI/Bluetooth traces, vehicle logs), and isolate root cause before handing off to firmware owners.
• Field issue triage: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.
• Defect lifecycle:Manage defects end-to-end in JIRA — clear reproduction steps, attached logs, severity rationale, fix verification, and regression follow-up.
• Test infrastructure:Maintain test benches, in-vehicle rigs, and diagnostic setups so they stay release-ready.
• Cross-functional communication: Partner with firmware leads, product managers, and integration partners to align on feature readiness and defect priority.

Required Qualifications:

• 8+ years in a hands‑on validation/QA engineering role on firmware or embedded products.
• Validation depth:Demonstrated experience writing and executing test plans/cases, identifying and closing coverage gaps, and managing defects through the full lifecycle.
• Connectivity background (any flavor):Hands‑on validation experience in at least one connectivity domain — Bluetooth, Wi‑Fi, cellular (LTE/5G), GNSS, or vehicle networking.
• Root‑cause skill:Strong log triage and debugging instincts; comfortable with Wireshark, DLT, ADB, and similar tooling.
• Field triage experience: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. (Python scripting is mandatory requirement).
• Strong defect‑tracking discipline (JIRA/Confluence) and experience in agile release cycles.

Preferred Qualifications:

• 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.

Education:

• Bachelor’s or Master’s degree in Computer Science, Computer or Electrical Engineering, Mathematics, or a related field.
