Senior RF Hardware Engineer
On-siteFull-timeHardware EngineeringTelecommunications
Design, develop, integrate, and validate RF circuits and subsystems for high-performance wireless and cellular communication devices. The role covers concept-to-production development, laboratory testing, debugging, performance optimization, schematic review, and PCB layout guidance. Work closelyでは?
Responsibilities
- Design, develop, and integrate RF circuits and subsystems from concept through mass production.
- Perform hands-on testing, debugging, and root-cause analysis of RF boards using advanced laboratory equipment.
- Evaluate and optimize impedance matching, output power, receiver sensitivity, EVM, ACLR, and emissions.
- Review complex electronic schematics and guide PCB layout for high-frequency RF circuits.
- Collaborate with system, mechanical, software, and manufacturing engineers on cellular module and RF component integration.
- Investigate and resolve complex RF hardware issues in new and legacy products.
Requirements
- B.Sc. in Electrical Engineering.
- At least 5 years of hands-on experience in RF hardware design, board-level testing, or hardware integration.
- Strong understanding of RF fundamentals, circuit theory, and components including amplifiers, filters, mixers, transceivers, and duplexers.
- Experience operating cellular communication testers.
- Experience with RF simulation tools such as ADS, CST, or HFSS.
Nice to have
- Knowledge of 3GPP specifications, cellular frequency bands, and radio testing parameters.
- Experience with cellular communication testers such as R&S CMW500, Anritsu MT8821C, or MT8000A.
- Availability for business travel of under 10%.
