Job description

Job Title: RF Test Engineer

Location: San Diego, California / Fremont, CA

Employment: FTE

1. Test Execution & System Validation

Configure, calibrate, and operate multi-axis OTA anechoic test chambers (e.g., ETS-Lindgren AMS systems) across FR1 (Sub-6 GHz) and FR2 (mmWave) frequency ranges.

Perform comprehensive radiated measurements including TRP, TIS, EIRP, EIS, and MIMO OTA throughput testing.

Validate satellite positioning performance by executing A-GNSS (GPS/Glonass/Galileo) OTA sensitivity evaluations.

Conduct systematic RF Desensitization (Desense) investigations to isolate internal platform noise (e.g., from display panels, high-speed digital buses, or power supplies) degrading receiver performance.

Maintain chamber verification logs, performing routine range calibrations (path loss measurements using standard gain horn antennas) to ensure measurement repeatability and system accuracy.

2. Test Plan Compliance & Certification

Execute testing matrices in strict accordance with CTIA Test Plan for Wireless Device Over-the-Air Performance, 3GPP Technical Specifications (TS 38.521 / 38.151), and specific North American wireless operator requirements.

Analyze test data against strict regulatory and carrier acceptance limits, identifying and logging edge-case failures.

Interface directly with the Telecommunications Certification Body (TCB) team and project managers to package validation data for formal regulatory submissions (FCC, CE, ISED).

Job Description

Requirements

• Strong hands-on experience in RF testing, wireless device validation, or cellular modem testing.
• Practical understanding of 5G NR SA, including FDD and TDD bands.
• Experience with Reference Sensitivity Testing and RF performance benchmarking.
• Familiarity with R&S, Keysight, Anritsu or equivalent cellular network simulators/test platforms.
• Ability to work with RF automation tools and execute algorithm-driven test flows.
• Understanding of 3GPP TS 38-521-1 test methodology, especially sensitivity-related test conditions.
• Experience working with RF parameters such as bandwidth, SCS, ARFCN, power class, MCS, Rx chain configuration, and transmission mode.
• Ability to analyze RF test results and identify correlation or discrepancies between test platforms.
• Working knowledge of data reporting formats such as CSV and dashboard/reporting tools such as Tableau.

Preferred Skills

• Prior experience supporting Customer or similar high-compliance product validation environments.
• Experience in conducted RF testing using shielded environments.
• Experience creating test matrices across bands, bandwidths, and radio configurations.
• Ability to validate vendor-provided automation test lists and cross-check them against 3GPP specifications.
• Strong documentation, issue tracking, and technical communication skills.
• Ability to work independently after project-specific training.

Tools / Equipment Exposure

R&S, Keysight, Anritsu test equipment

Deliverables

• Band-by-band RF test results comparing Test platforms.
• Test case-level correlation data across applicable 3GPP-based configurations.
• Discrepancy reports highlighting gaps or issues observed during testing.
• Results in CSV or Tableau format, as agreed with the project team.
• Regular status updates through weekly meetings and email follow-ups with Customer and Tech Mahindra DRIs.

Experience and Education

Experience: 5 7 years in RF testing, cellular modem validation, 5G NR validation, wireless device testing, or telecom productization testing.

Education: Bachelor's degree in Electronics, Electrical Engineering, Telecommunications, Computer Engineering, or a related technical field.
