Wireless Firmware Validation Engineer

Job description

As a Wireless Firmware Validation Engineer on the Firmware team, you will own the performance validation, optimization, and debugging of our TCU (Telematics Control Unit). Managing a complex architecture that integrates third-party hardware with our autonomous vehicle platform, you will analyze diagnostics and log outputs across cellular networks, 4G/5G modems, internal software layers, Wi-Fi, and Bluetooth.

Your work will directly safeguard the safety, reliability, and scaling of the Zoox autonomous fleet. Robust, low-latency connectivity is fundamental to autonomous vehicle deployment, powering essential real-time cloud services, fleet management pipelines, and teleoperation capabilities.

Job responsibilities

  • Test Architecture & Strategy: Define component integration plans (from initial hardware bring-up to advanced functions), then design, develop, and execute comprehensive test plans spanning early development through…
  • Advanced Testing Campaigns: Proactively design and facilitate advanced testing campaigns utilizing industry-standard network emulation tools (e.g., Keysight UXM) to identify cellular edge cases, performance…
  • Deep Debugging: Dig into challenging log reviews and cross-functional system integration mysteries to identify root causes. Propose solutions balancing long-term architectural goals with near-term operational needs.
  • Interface Validation: Ensure all interfaces are well-architected, documented, and rigorously validated—notably between RF-baseband, baseband-protocol stack (AP), and AP to host.
  • Automation & Frameworks: Develop and enhance log frameworks and automation scripts to analyze wireless communication behavior at scale.
  • Cross-Functional Collaboration: Review (and if necessary adjust or author) the Software, Firmware, and integration design specifications and requirements for Zoox’s

Job requirements

  • B.S. or M.S. degree in Electrical Engineering, Telecommunications, Computer Science, or a similar discipline with 10+ years of industry experience in wireless validation or embedded systems test engineering.
  • Validation Expertise: Deep expertise in developing 3GPP cellular (4G-LTE, 5G-NR), Wi-Fi, and Satellite feature test plans, as well as debugging protocol layers (MAC, L1, RF, FW).
  • Protocol Knowledge: Extensive expertise in LTE/5G Protocol Stacks (NAS, PDCP, RRC, RLC, MAC, PHY) and interpreting 3GPP specifications.
  • Network Analysis Tools: Exceptional ability to use cellular network analysis tools (e.g., QXDM , Shannon Tools, Wireshark) to capture, parse, and analyze complex cross-layer wireless behaviors.
  • Emulation & Lab Tools: Proven hands-on experience with industry-standard network emulators (e.g., Keysight UXM, Rohde & Schwarz CMW500/CMX500) for baseband testing and hardware bring-up.
  • Programming/Automation: Strong proficiency in Python or Shell scripting for building and maintaining automated test frameworks.
  • Familiarity with other wireless technologies (Wi-Fi, Bluetooth, BLE).
  • Experience testing software within an embedded Linux or Yocto Project environment.
