About the role

Engineering role focused on validation, performance testing, and debugging of the Telematics Control Unit (TCU) to ensure robust cellular, Wi‑Fi, and Bluetooth connectivity for Zoox autonomous vehicles.

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 large-scale operational fleet deployment.
  • 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 bottlenecks, and vulnerabilities.
  • 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 operations.

Qualifications

  • 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.
