Cellular Systems Engineer

6+ Months contract

Location: Foster City -Onsite in Foster City, CA | 5 days in office

• Client is developing the first ground-up, fully autonomous vehicle fleet and the supporting ecosystem
• required to bring this technology to market. Sitting at the intersection of artificial intelligence, robotics, and
• design, aims to provide the next generation of mobility-as-a-service in urban environments. We're
• looking for top talent that shares our passion and wants to be part of a fast-moving and highly
• execution-oriented team.
• Responsibilities:
• You will work closely with field deployment optimization teams across connectivity system, firmware and
• software engineer teams to identify, record, process and interpret key device and service performance
• attributes.
• You will act as the primary technical expert for analyzing modem-level field logs from chipsets such as
• Qualcomm (QXDM) and Samsung (Shannon), leading the development of programmatic tools to identify
• root causes for throughput drops, handover failures, Radio Link Failure, and connectivity instabilities. You
• will develop end-to-end automation tools required to facilitate the identification and processing of these
• attributes at scale.
• You will interpret key device and service performance attributes (KPIs). You will recommend
• reconfigurations or architectural tweaks to the client design process to improve e2e QoS.
• You will work closely with system architecture and engineers to deliver system architecture, requirements,
• design and prototype in the connectivity domain (4G-LTE, 5G NR, WiFi/GPS) to meet end-to-end
• quality-of-service of autonomous driving use case requirements.

Qualifications:

• B.Eng/M.S. in Electrical Engineering, Telecommunications, or a related field

• Expert-level knowledge of 4G-LTE and 5G-NR air interfaces, specifically L1-L3 (PHY, MAC, RLC, PDCP,

RRC, and NAS).

• Familiarity with IEEE 802.11 (a/b/g/n/ac/6/6E/7) protocols and TCP/IP networking.

• Deep, hands-on experience with modem-level chipset tools (e.g., Qualcomm QXDM/QCAT, Samsung

ShannonDM, Wireshark).

• Proven track record of troubleshooting complex end-to-end live network performance issues, including

mobility management, interference analysis, and call drop etc.

• Strong proficiency in Python is required for automation tools development and log analysis; other

scripting languages are optional.

• Familiarity with RAN and Core Network architecture; ability to see beyond the log and understand how

end-to-end components impact the system performance.

• 3–5+ years of professional experience specifically in the cellular protocol domain
