Wireless Firmware Validation Engineer

In this role, you will: * 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 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. Bonus Qualifications * Familiarity with other wireless technologies (Wi-Fi, Bluetooth, BLE). * Experience testing software within an embedded Linux or Yocto Project environment. * Prior experience in the autonomous vehicle, telematics, or IoT space, where connectivity directly impacts physical safety and fleet operations. * A proven track record of driving continuous improvements, mentoring fellow engineers, and promoting best validation practices across organizations.
