• 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

• 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.
