Wireless Firmware Validation Engineer

Responsibilities

• Test architecture and strategy: Define component integration plans from initial hardware bring-up to advanced functions, design, develop, and execute comprehensive test plans spanning early development through large-scale operational fleet deployment.
• 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.
• Deeply debug 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.

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.
• 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).
• Extensive expertise in LTE/5G Protocol Stacks (NAS, PDCP, RRC, RLC, MAC, PHY) and interpreting 3GPP specifications.
• Exceptional ability to use cellular network analysis tools (e.g., QXDM , Shannon Tools, Wireshark) to capture, parse, and analyze complex cross-layer wireless behaviors.
• Proven hands-on experience with industry-standard network emulators (e.g., Keysight UXM, Rohde & Schwarz CMW500/CMX500) for baseband testing and hardware bring-up.
• Strong proficiency in Python or Shell scripting for building and maintaining automated test frameworks.
