Prodapt is seeking a highly skilled
5G Protocol & Certification Engineer in Fremont, CA to focus on the signaling and functional verification of cutting-edge mobile devices, ensuring they meet stringent carrier and emergency service requirements. In this role, you will develop and execute protocol test plans, perform deep-dive modem log analysis, and collaborate closely with OEM and network teams to drive certification closure on complex 5G features.
Responsibilities
- Develop and execute comprehensive protocol verification plans for 5G/LTE designs, including defining test strategies for E911, RTT, and LPPe/PIDF-LO protocols.
- Design, develop, and maintain test environments using Keysight, Rohde & Schwarz, or Spirent simulators to verify 5G functionality, mobility, and IMS features.
- Create complex test scenarios and test cases to achieve comprehensive Carrier Certification (AT&T, Verizon, T-Mobile) and 3GPP standards compliance.
- Analyze modem logs and regression results, debug complex signaling issues using QXDM, QCAT, and Wireshark, identify root causes, and drive bug resolution.
- Work closely with cross-functional teams, including Modem SW, Architecture, and Carrier Labs, to align verification efforts with project milestones.
- Maintain accurate and up-to-date documentation for verification plans, test cases, and results to support traceability and final device approval.
Requirements
- Bachelors degree in Computer science, Computer Engineering, Electrical Engineering, Electronics & Communication engineering or related field.
- 10+ years of telecom industry experience with 5G/LTE/Modem development or validation.
- 5+ years of hands-on experience in 5G Protocol Verification or closely related Modem/Signaling subsystem verification.
- Strong proficiency in 3GPP Standards (Rel 15/16) and IMS Signaling for block-level and/or system-level verification.
- Experience with industry-standard protocol tools (QXDM, QCAT, Wireshark, ADB) and coverage-driven certification flows.
- Proficiency with scripting languages such as Python for automation, regression management, and data analysis.
- Demonstrated strength in modem debugging, root-cause analysis, and driving verification closure for E911/Location Services.
- Excellent communication and interpersonal skills, with the ability to work effectively in a collaborative, cross-functional environment.
