Job description

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


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)
