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.
