You will join the PA Design team in PEU Radio Pacific Chengdu, responsible for the full PA lifecycle in our radio products – from concept to volume production. As a senior PA developer (JS7), you act as a technical expert and key individual contributor, driving high-performance, high-efficiency PA solutions and supporting the team with deep technical leadership, ownership and collaboration.
Lead RF/microwave PA design, simulation and optimization for radio products from concept to maintenance.
Define PA architectures and design strategies based on system and product requirements.
Perform PA simulations (e.g. ADS, AWR, HFSS) and secure good correlation with lab results.
Plan and execute PA lab measurements, tuning designs to meet efficiency, linearity and robustness targets.
Independently debug complex PA issues from simulation to HW bring-up, documenting root causes and improvements.
Collaborate with system, RF, HW, test and manufacturing teams to secure robust, volume-ready implementations.
Mentor junior engineers, share PA design best practices and contribute to technical reviews.
Master’s degree or above in Electronics, Electrical Engineering, RF/Microwave Engineering or related field.
Strong understanding of RF/microwave fundamentals and PA design principles.
Solid hands-on experience in RF or PA design (schematic and layout), with exposure to RF power devices and front-end modules.
Proficiency with RF/EM simulation tools (e.g. ADS, AWR, HFSS) and ability to correlate simulation and measurement results.
Experience in PA lab validation and measurement (e.g. S-parameters, gain, P1dB, ACLR, EVM, efficiency), including tuning and troubleshooting.
Proven independent design/debug capability, strong problem-solving skills and end-to-end ownership.
RF-related work experience (e.g. PA, RF front-end, radio HW or similar domains), preferably in R&D or project-driven organizations.
Good communication skills and collaborative mindset, willing to continuously learn.
Previous exposure to the ICT or other high-tech industries is a strong plus.
