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 Responsibilities
Troubleshooting & 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.
