Day-to-Day Responsibilities: Cellular Test Engineer (5G NR / LTE)
Test execution & validation
- Execute conformance, functional, and regression test campaigns on 5G NR (SA/NSA) and LTE devices, covering RRC/NAS signaling, mobility, carrier aggregation, and data-throughput scenarios.
- Validate radio protocol behavior against 3GPP specs and log findings with clear reproduction steps.
- Run RF performance measurements (TX power, sensitivity, EVM, spurious emissions, throughput vs. signal level) and compare results against product requirements.
Automation on CMX/CMW
- Build, maintain, and extend automated test scripts and suites on Rohde & Schwarz CMX500/CMW callbox platforms.
- Own the nightly/weekly automated regression pipeline: monitor runs, triage failures, and keep the suite . as firmware drops land.
- Develop Python tooling for test sequencing, instrument control, result parsing, and reporting; reduce manual test time through incremental automation.
Lab bench & hardware debug
- Set up and operate lab benches: callboxes, spectrum/signal analyzers, power supplies, attenuators, shield boxes, and RF cabling.
- Use an oscilloscope for signal integrity, timing, and power-sequencing debug on device hardware; isolate whether an issue is RF, protocol, or hardware in origin.
- Maintain bench calibration, cable loss characterization, and equipment health; keep test setups documented and reproducible.
Debug & cross-functional work
- Analyze protocol logs (QXDM/QCAT, modem traces, callbox logs) to root-cause failures and narrow them to a specific layer or component.
- Partner with firmware, RF, and hardware engineers to reproduce issues, verify fixes, and confirm no regressions.
- File, track, and drive defects to closure; escalate blockers affecting release milestones.
Reporting & continuous improvement
- Produce daily/weekly test status summaries: pass rates, new failures, coverage gaps, and blocking issues.
- Contribute to test plan development for new features, chipsets, and bands; expand coverage where automation or scenarios are thin.
- Document test procedures, bench configurations, and known issues so results are repeatable across engineers and sites.
Must have skills:
- The ideal candidate has hands-on experience with cellular testing across both 5G NR and LTE technologies, including radio protocol validation, RF performance, and conformance/functional test execution.
- They should be proficient with test automation on CMX (Rohde & Schwarz CMX500/CMW callbox platforms), building and maintaining automated test scripts and regression suites.
- Strong lab bench skills are expected, including confident use of an oscilloscope and related instrumentation for signal integrity, timing, and hardware debug.
- Familiarity with scripting (e.g., Python) for test automation, along with a solid grasp of cellular signaling and measurement fundamentals, will round out the profile.
- Bachelor s degree in engineering.
Preferred Qualifications:
- Master's degree in Computer Engineering or Electrical Engineering
- Lab - engineer experience
- Engineering degree preferred
