RFFE System Feature Engineer Senior Staff

General Summary:
Role Overview
We are looking for a RF front-end (RFFE) System Feature Engineer to contribute to the development, testing, and optimization of advanced modem features across the full RF signal chain. The role focuses on improving performance of both transmit (TX) and receive (RX) paths, spanning modem software, transceiver architecture, and RFFE components up to the antenna. The position requires a hands-on engineer with strong analytical skills and a passion for experimental validation in lab environments.
Key Responsibilities

Develop, test, and investigate new modem features to optimize TX and RX RFFE chains
Evaluate system-level performance across modem software and RF front-end devices (PA, PA Module with integrated Duplexers (PAMiD), DRX modules, antenna interface)
Design and execute lab experiments, including setup, measurement, and analysis
Collaborate with cross-functional teams (RF design, modem software, system engineering, product marketing)
Provide clear and structured technical reporting and communicate findings effectively

Technical Scope

RF front-end systems (PA, LNA, PAMiD, DRX, antenna tuning)
System-level TX/RX optimization and validation
Modem algorithms and features
Transceiver signal processing

Minimum Qualifications:
• Bachelor’s degree in Engineering, Information Systems, Computer Science, or related field and 2+ years of Software Engineering or related work experience.
OR
Master’s degree in Engineering, Information Systems, Computer Science, or related field and 1+ year of Software Engineering or related work experience.
OR
PhD in Engineering, Information Systems, Computer Science, or related field.

• 2+ years of academic or work experience with Programming Language such as C, C++, Java, Python, etc.
Required Skills & Experience – Core Skills

Experience with software development and scripting
RF simulations
Python and/or Matlab
RF lab equipment (spectrum analyzers, signal generators, etc.)
Signal processing

Technical Knowledge

System-level understanding of the full RF path (modem to antenna)
TX and RX signal chain architecture
PA/LNA behavior and performance metrics
Understanding of WWAN protocols (3GPP, 4G, 5G, 6G, WiFi)
Up to date on recent AI, NN, LLM, and Agentic System developments

Profile

Experience: 3–5 years
Target level: Senior or Staff Engineer
Strong communication skills and collaborative mindset
Initiating and ideating new modem feature development
Strong experimental mindset with focus on lab-based validation
Clear and efficient reporting abilities
