Staff or Senior Staff RF Hardware Design Engineer

We are seeking a highly skilled and motivated Staff or Senior Staff RF/Hardware Design Engineer to lead the development of advanced 5G radio hardware. The ideal candidate will possess in-depth technical expertise in RF circuit design, system integration, and validation for wireless infrastructure or user equipment, along with proven experience in delivering high-performance designs from concept through production.

You will work closely with cross-functional teams, including system architects, digital designers, and firmware engineers, to define and implement next-generation 5G hardware infrastructure platforms that push the limits of performance, reliability, and efficiency.

Key Responsibilities:

• Lead the design and development of RF, supply, and RF circuits for front-end (RFFE) and transceiver modules for 4G and 5G NR (sub-6 GHz) systems.
• Perform schematic capture, component selection, simulation, layout review, and design optimization for performance, manufacturability, and cost.
• Define and execute RF test plans, including S-parameter, noise figure, linearity, P1dB, IIP3, VSWR, and ACLR measurements.
• Drive PCB design reviews, ensuring proper RF layout techniques, grounding, impedance control, and thermal design.
• Collaborate with system and baseband teams to define RF system architecture, interfaces, and calibration requirements.
• Conduct signal integrity (SI) and power integrity (PI) analysis for high-speed digital and mixed-signal sections.
• Support bring-up, troubleshooting, and validation of prototypes in the lab.
• Provide technical mentorship to junior engineers and contribute to long-term hardware roadmap planning

Job Requirements:

• Master’s degree in Electrical Engineering, Electronics, or related field
• 10+ years of hands-on experience in RF/hardware design for wireless communication systems
• Strong knowledge of RF circuit design, including LNAs, PAs, mixers, PLLs, filters, power supply, clock and matching networks
• Experience with RF simulation tools (Keysight ADS, Cadence AWR, or equivalent)
• Proficiency with schematic capture and PCB layout tools (Cadence Allegro, Altium, etc.)
• Solid understanding of RF specifications, including RF performance metrics
• Hands-on lab experience with RF instruments: vector network analyzers, spectrum analyzers, signal generators, and oscilloscopes
• Experience in system-level debugging and hardware bring-up
• Excellent problem-solving and communication skills, with a strong ability to collaborate in cross-functional teams

Desirable Skills:

• Experience with mass production design for 5G infrastructure, small cells, or mobile platforms
• Understanding thermal design and mechanical constraints in RF systems
• Experience with EMC/EMI design and compliance testing
• Advanced degree (Ph.D.) in RF/Microwave Engineering or related field
