Cellular Systems Engineer

JOB TITLE: Cellular Systems Engineer
LOCATION: Foster City, CA (Onsite)
PAY RANGE: $70 - $80/hr.
DURATION: 6 Months


TOP 3 SKILLS:

• Expert-level knowledge of 4G-LTE and 5G-NR air interfaces (L1-L3: PHY, MAC, RLC, PDCP, RRC, NAS) and familiarity with IEEE 802.11 protocols and TCP/IP networking.
• Hands-on experience with modem-level chipset tools (e.g., Qualcomm QXDM/QCAT, Samsung ShannonDM, Wireshark) and proven ability to troubleshoot complex end-to-end network performance issues.
• Strong Python proficiency for automation and log analysis, with 3-5+ years of professional experience in the cellular protocol domain.

Job Description:
The company 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, the company 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:

• Work closely with field deployment optimization teams across connectivity systems, firmware, and software engineering teams to identify, record, process, and interpret key device and service performance attributes.
• 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.
• Develop end-to-end automation tools required to facilitate the identification and processing of these attributes at scale.
• Interpret key device and service performance attributes (KPIs) and recommend reconfigurations or architectural tweaks to the design process to improve end-to-end QoS.
• Work closely with system architects and engineers to deliver system architecture, requirements, design, and prototypes in the connectivity domain (4G-LTE, 5G NR, WiFi/GPS) to meet end-to-end quality-of-service requirements for autonomous driving use cases.

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 drops
• Strong proficiency in Python for automation tools development and log analysis; other scripting languages optional
• Familiarity with RAN and Core Network architecture; ability to see beyond the log and understand how end-to-end components impact system performance
• 3-5+ years of professional experience specifically in the cellular protocol domain
