You will develop new radio variants, improve existing products and review RF designs delivered by external engineering partners. This is a hands-on, founding role in our new hardware engineering team in Suzhou, working closely with global system engineering and hardware colleagues.\n\nResponsibilities:\nDesign and optimize RF transmit and receive chains, including power amplifiers (PA), low-noise amplifiers (LNA), filters, matching networks and transceiver interfaces.\nDevelop radio designs across power classes, frequency bands and bandwidths, for both FDD and TDD operation.\nPerform RF simulation, characterization and troubleshooting.\nOptimize RF performance, efficiency, thermal behavior and component cost.\nLead RF component substitutions and end-of-life (EOL) redesigns.\nReview and validate RF designs delivered by external engineering partners against ANDREW requirements.\nDefine RF test requirements and support design verification testing (DVT), production test development and RF calibration.\nSupport regulatory and conformance testing for global markets.\nDocument design rationale and contribute to RF design guidelines and reusable design blocks.\n\nRequired Skills:\n8+ years in RF hardware design for wireless infrastructure.\nStrong understanding of RF circuits, power amplifiers, digital predistortion (DPD), impedance matching and RF measurements.\nExperience with LTE and 5G NR radio products, DAS, repeaters or O-RUs.\nExperience with both FDD and TDD radio designs.\nProficiency with RF simulation tools (such as Keysight ADS or AWR Microwave Office) and lab instruments, including signal analyzers, spectrum analyzers and network analyzers.\nSolid knowledge of EVM, ACLR, gain, noise figure, linearity and efficiency measurements.\nFamiliarity with 3GPP base station conformance requirements (TS 36.141 and TS 38.141).\nAbility to review third-party designs critically and communicate findings clearly.\nExperience working across global, cross-functional engineering teams.\nProfessional working proficiency in English and Mandarin Chinese.\n\nRequired Education and Experience:\nBS or MS in Electrical Engineering or related field with 8+ years of relevant experience.\nExperience with Tier-1 vendors or operator deployments strongly preferred.","description_format":"text","description_chars":2470,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate
