Job description

Senior RF System Engineering Expert Description

Serve as the technical focal point for advanced RF and physical layer (PHY) modem systems, driving the definition, analysis, and hands‑on performance verification of next-generation wireless architectures. In this role, you bridge baseband signal processing and analog RF hardware, taking architectural and technical ownership of link performance, system behavior, and end-to-end functionality.

Requirements

• Must Have Experience: 12+ years of hands‑on engineering experience in RF and physical layer (PHY) system design, analysis, or performance engineering for wireless communications.
• System & Performance Scope: Proven track record defining and executing system evaluations associated with RF, baseband, PHY, and modem performance.
• Programming & Data Analysis: Advanced proficiency in Python and/or MATLAB for algorithm validation, data analysis, instrument automation, and custom test script development.
• RF Test & Measurement Expertise: Deep practical knowledge in operating high-frequency RF test equipment, including spectrum analyzers, signal generators, power meters, and vector network analyzers (VNAs).
• System Debugging Intuition: Exceptional deep‑dive debugging skills capable of isolating issues across the boundaries of RF, digital hardware, and physical layer software.
• RF Principles: Solid understanding of RF chains and parameters, including Noise Figure (NF), third‑order intercept point (IP3), return loss (RL), and receiver architectures (Superheterodyne / Zero-IF).
• Communication & Documentation: Excellent verbal and written communication skills in English, with a proven ability to author technical system documents and specifications.
• Nice to have Digital Communications & Impairments: Practical knowledge of I/Q modulation (QAM, PSK), Digital Predistortion (DPD), Automatic Gain Control (AGC), and Error Vector Magnitude (EVM) characterization.
• Cross-Functional Interface: Experience acting as a technical bridge or focal point communicating directly with RFIC design, algorithm, software, and firmware teams.
• Engineering Mindset: Strong pragmatic problem-solving skills, broad system‑level perspective, and a collaborative approach in multidisciplinary engineering environments.
