What is an LTE system engineer?

LTE System Engineers are professionals who design, implement, and optimize Long-Term Evolution (LTE) wireless communication systems. They are responsible for ensuring efficient network performance, troubleshooting issues, and integrating new technologies within LTE networks. Their work involves collaborating with hardware and software teams, conducting system tests, and keeping up to date with industry standards to maintain seamless wireless connectivity.

What are some typical challenges an LTE system engineer faces when optimizing network performance?

LTE System Engineers often encounter challenges such as managing network congestion, minimizing latency, and ensuring seamless handovers between cells. They must analyze large sets of performance data to identify coverage gaps or interference issues, and work closely with cross-functional teams—including RF engineers and software developers—to deploy solutions. Staying current with evolving LTE standards and integrating new technologies into existing infrastructure are also common aspects of the role. Effective communication and problem-solving skills are essential to address these dynamic challenges.

What are the key skills and qualifications needed to thrive as an LTE system engineer, and why are they important?

To thrive as an LTE System Engineer, you need a solid background in wireless communications, cellular network architecture, and RF engineering, typically supported by a degree in electrical engineering or a related field. Familiarity with technical tools such as network simulation software, protocol analyzers, and certifications like 3GPP or relevant vendor certifications are commonly required. Strong analytical thinking, problem-solving, and effective collaboration skills distinguish top performers in this role. These capabilities are essential for designing, optimizing, and maintaining reliable LTE networks that meet performance standards and support seamless connectivity.

What is the difference between Lte System Engineer vs Radio Network Engineer?

AspectLte System EngineerRadio Network Engineer
CertificationsLTE, 4G/5G certifications, Cisco, NokiaRF, LTE, 4G/5G certifications, Cisco, Nokia
Work EnvironmentTelecom companies, network providers, field and officeTelecom companies, network providers, field and office
Job FocusLTE network design, optimization, integrationRadio frequency planning, coverage, interference management

Both roles involve working with LTE networks within telecom environments, often sharing certifications and work settings. The Lte System Engineer primarily focuses on LTE system design, deployment, and optimization, while the Radio Network Engineer emphasizes RF planning and coverage analysis. Understanding these distinctions helps in choosing the right career path or job search focus.

Job description

Syntronic-LTE Validation Engineer

Are you ready to be part of a leading global engineering design house specializing in the design and development of state-of-the-art embedded hardware, electronics, and electro-mechanics?

What we’re looking for:

•          Highly motivated professionals

•          Motivated test technician

•          Professionals with ability to work both with in-house projects and on-site assignments at our customers’ locations

 

Primary Role: We are seeking a LTE / 5G RedCap Validation Engineer to lead cellular protocol and RF validation. You will be responsible for end-to-end testing of cellular modems integrated into consumer IoT products, ensuring flawless performance across LTE Cat-M, Cat-1bis, and emerging 5G NR RedCap (Reduced Capability) technologies. Your work will directly impact device certification, carrier acceptance, and real-world user experience
 

Key Responsibilities

Protocol & RF Validation

  • Design, develop, and execute validation test plans for LTE (Cat-1/Cat-4/Cat-M1/NB-IoT) and 5G NR RedCap modems integrated into Lab126 devices
  • Perform conformance, functional, and performance testing including attach procedures, mobility, handovers, PDU session establishment, DRX/eDRX/PSM power-saving modes, and RRC state transitions
  • Validate RF parametric performance: TX power, ACLR, EVM, spectrum emissions, RX sensitivity, and blocking across LTE/5G NR bands (FR1)
  • Execute carrier acceptance testing (Verizon OTA, AT&T PTCRB, T-Mobile, Vodafone, DT, KDDI) and support GCF/PTCRB certification campaigns

Test Equipment & Lab Operations

  • Hands-on execution using Rohde & Schwarz CMW500, CMX500, and Anritsu MT8000A / MD8475B callboxes for signaling and non-signaling test modes
  • Configure end-to-end call scenarios: VoLTE, VoNR, SMS over IMS, ePDG/Wi-Fi calling, data throughput (DL/UL), CA (Carrier Aggregation), MIMO
  • Set up and operate supporting instrumentation: spectrum analyzers, vector signal generators, network emulators, RF shielded chambers, fading simulators (e.g., Spirent, Keysight PROPSIM)
  • Automate test execution using Python, TTCN-3, or vendor SDKs (R&S CMWrun, Anritsu Rapid Test Designer)

Debug & Root Cause Analysis

  • Analyze modem logs (QXDM/QCAT for Qualcomm, ELT for MediaTek), Wireshark captures, and layer-3 signaling traces to isolate protocol failures
  • Collaborate with modem vendors (Qualcomm, MediaTek, Sequans, Sony Altair) and chipset teams to drive firmware fixes
  • Reproduce field issues in the lab and provide detailed defect reports with RF/protocol evidence

Cross-functional Collaboration

  • Partner with firmware, hardware, antenna, and systems engineering teams during EVT/DVT/PVT phases
  • Support field trials with carrier partners and international deployments
  • Contribute to test coverage strategy for new features: 5G RedCap Rel-17/18, Network Slicing, NTN (Non-Terrestrial Networks)

What you’ll like about us:

  • Company Culture – outstanding people and a flexible work environment.
  • Career Growth Opportunities – being a design house keeps variety in your work. New opportunities happening all the time!
