Embedded Network Optimization Engineer

Job Title: Embedded Network Optimization Engineer (Multi-OEM Support – Samsung, Nokia, Ericsson) Position Overview We are seeking a highly skilled Embedded Network Optimization Engineer to work directly with mobile network operators, providing end-to-end troubleshooting, performance tuning, and optimization for device-to-network interaction across multi-vendor RAN environments (Samsung, Nokia, and Ericsson). This role is embedded within the operator’s operational workflow to ensure rapid resolution of device-related issues, chipset-level insights, and vendor-agnostic optimization. You will act as the primary bridge between the operator’s engineering teams, Qualcomm R&D, and OEM vendor support teams. Key ResponsibilitiesTroubleshooting & RCA - Serve as the primary technical interface for device-related network performance issues across Samsung, Nokia, and Ericsson RAN environments. - Collect and analyze device modem logs, chipset traces, and network KPIs to identify and isolate root causes. - Replicate and simulate issues in lab environments when needed. Network Optimization - Analyze and optimize RAN parameters (handover thresholds, power control, carrier aggregation settings, VoLTE/VoNR configurations) to improve device performance. - Propose vendor-specific parameter adjustments to maximize interoperability between devices and network equipment. - Support mobility, throughput, and coverage optimization across LTE, 5G NSA, 5G SA, and emerging technologies. Multi-OEM Coordination - Liaise with Samsung, Nokia, and Ericsson support teams to align parameter changes, firmware updates, and network feature rollouts. - Understand OEM-specific RAN software versions, feature sets, and known issues impacting device performance. - Track and document vendor-specific fixes and monitor their implementation. Firmware & Feature Validation - Assist in validating chipset firmware builds before commercial deployment. - Support operator trials for new RAN features (VoNR, 5G NR CA, DSS, satellite connectivity, etc.). - Conduct regression testing post-software or parameter changes. Operator Integration - Participate in operator troubleshooting calls, optimization workshops, and incident response reviews. - Provide real-time recommendations during major network events and escalations. - Maintain strong working relationships with operator engineering, field, and NOC teams. Reporting & Documentation - Generate weekly and monthly performance reports highlighting trends, RCA summaries, and recommendations. - Maintain a knowledge base of recurring issues, fixes, and optimization scripts. - Document OEM-specific troubleshooting workflows for internal use. Training & Enablement - Train operator engineers on Qualcomm diagnostic tools (QXDM, QCAT) and OEM vendor tools. - Share best practices for multi-vendor network optimization and device log interpretation. Required Qualifications - Bachelor’s degree in Electrical Engineering, Telecommunications, or related field (Master’s preferred). - 5+ years of experience in RAN optimization, network performance, or device interoperability support. - Hands-on experience with Samsung, Nokia, and Ericsson RAN systems, parameters, and troubleshooting tools. - Strong knowledge of LTE, 5G NSA/SA, VoLTE, VoNR, and related call flows. - Familiarity with Qualcomm chipset logging and analysis tools. - Proven ability to coordinate between operators, OEM vendors, and chipset manufacturers. - Strong problem-solving skills, with the ability to analyze complex, multi-variable performance issues. Preferred Skills - OEM vendor certification in Nokia NetAct, Ericsson OSS, or Samsung ENM. - Field experience with drive testing and walk testing (e.G., TEMS, Nemo, IBwave). - Understanding of RF propagation, interference management, and spectrum utilization. - Experience with lab simulations and network feature validation. - Strong reporting and presentation skills. Work Environment - Hybrid role with a mix of on-site operator presence and remote analysis. - May require occasional travel to operator locations, vendor labs, or field test sites. - Fast-paced environment requiring close collaboration with cross-functional teams.
