Cellular Systems Engineer

Kforce Inc; San Mateo (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Kforce Inc. in Foster City, CA, is seeking a Cellular Systems Engineer to join a fast-moving team at the intersection of AI, robotics and mobility services.

You will analyze modem-level logs from Qualcomm and Samsung chipsets, develop automation tools, and work with 4G-LTE/5G-NR, WiFi/GPS, to ensure end-to-end QoS for autonomous-driving use cases. Proficiency in Python required.

Qualifications

• > B.Eng/M.S. in Electrical Engineering, Telecommunications, or a related field.
• > 3-5+ years of professional experience specifically in the cellular protocol domain.
• > Expert-level knowledge of 4G-LTE and 5G-NR air interfaces, specifically L1-L3 (PHY, MAC, RLC, PDCP, RRC, 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.

Responsibilities

• 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.
• Act as the primary technical expert for analyzing modem-level field logs from chipsets such as Qualcomm QXDM/QCAT 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). You will recommend reconfigurations or architectural tweaks to the design process to improve e2e QoS.
• 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.
