Location:
Sunnyvale, CA (Onsite 5 days a week)
Salary Range:
Competitive Pay of up to $90/hr on W2
Introduction
This position requires an experienced Wireless Systems Embedded Firmware Engineer to contribute to the development and testing of cutting-edge 5G NR and LTE technologies. The role involves working in a dynamic lab environment, executing various test campaigns, and ensuring the reliability and performance of wireless systems.
Required Skills & Qualifications
- Bachelor's degree in Engineering.
- Hands-on experience with cellular testing across both 5G NR and LTE technologies, including radio protocol validation, RF performance, and conformance/functional test execution.
- 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, 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.
- Prior work experience at client or in client's Industry.
- Applicants must be able to work directly for Artech on W2.
Preferred Skills & Qualifications
- Master's degree in Computer Engineering or Electrical Engineering.
- Experience in lab engineering.
- Experience working with *** on exciting upcoming projects and testing new items in a lab environment.
Day-to-Day Responsibilities
- 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.
- Build, maintain, and extend automated test scripts and suites on Rohde & Schwarz CMX500/CMW callbox platforms.
- Develop Python tooling for test sequencing, instrument control, result parsing, and reporting; reduce manual test time through incremental automation.
- 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.
- 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.
Company Benefits & Culture
- Work with a team of innovative engineers on cutting-edge wireless technology.
- Opportunities for professional growth and development.
- Engage in exciting projects that push the boundaries of wireless systems technology.
