Sr. Test Engineer

Core Responsibilities

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).

Technical Requirements & Qualifications

Education & Experience

• Bachelors degree in electrical engineering Telecommunications or a highly related technical discipline (Masters Degree with an RF/Electromagnetics focus preferred).
• 2 to 5 years of direct hands-on experience in an RF laboratory environment specifically executing OTA testing.

Technical Skills & Instrumentation Knowledge

• Chamber Architectures: Deep familiarity with conical-cut and great-circle-cut anechoic chamber testing geometries.
• Wireless Protocols: Solid baseline knowledge of 5G NR (SA/NSA) LTE Advanced Wi-Fi 7 / 6E (802.11be/ax) Bluetooth and UWB physical layer parameters.
• RF Test Equipment: Hands-on operational mastery of network analyzers spectrum analyzers and radio communication testers (e.g. Keysight UXM 5G Rohde & Schwarz CMX500 / CMW500 Anritsu MT8000A).
• Software & Automation: Experience utilizing automated lab software suites (e.g. ETS-Lindgren EMQuest R&S AMS32). Proficiency in Python for parsing .csv data files and interfacing with instrument APIs is highly preferred.
• Foundational Knowledge: Solid grasp of Smith charts impedance matching polarization alignment Friis transmission equations and measurement uncertainty calculations.
• Soft Skills & Workplace Competencies
• Analytical Problem Solving: A methodical approach to isolating variables when troubleshooting system anomalies or uncharacteristic device failures inside the chamber.
• Meticulous Documentation: Strong attention to detail when logging hardware configurations test settings and EUT (Equipment Under Test) software build versions.
• Communication: Ability to clearly explain complex radiated failures and spatial pattern nulls to non-RF internal partners.
