Radio HW Design Power Amplifier

Join our Team
About us
Ericsson is opening a state-of-the-art R&D center in Yokohama focused on Radio and Software development. This new hub will support leading Japanese CSPs, partner with local vendors and deliver Japan-driven products and solutions that shape networks worldwide. We are establishing and growing the team and building advanced laboratory and office facilities. We are hiring across different experience levels - from early-career engineers to experienced developers and technical leaders.
The opportunity
We are looking for passionate and driven Radio HW Design Power Amplifier Engineer to join our team.
We are now looking for an Intermediate or Senior Power Amplifier (PA) Designer to join our growing and highly diverse team. In this role, you will develop power amplifiers for Ericsson's future Radio Systems, contributing across the full product lifecycle-from early study to deployed products and after-market support.
Our portfolio spans all relevant power levels and frequency bands used in mobile narrowband and broadband applications. You will work in an environment that values innovation, technical excellence, and collaboration across disciplines and organizations.
As a Power Amplifier (PA) Designer you will develop PAs for Ericsson future Radio Systems. We are working on all horizons: pre-product, product development as well as after-market. The amplifiers cover all applicable power levels and frequencies used for mobile narrow band and broadband applications.
This is an opportunity to develop as a professional in selected areas through work across various areas of pre-development, product development and aftermarket activities. This is an opportunity to design radio products that will be part of Ericsson's portfolio deployed in Japan and globally and contribute to Ericsson's Technology Leadership.
A HW Integration member in PEU Radio is responsible for making the radio hardware work as a complete system-by integrating boards, modules, software, and test environments, and by verifying that the product meets technical, regulatory, and quality requirements before release.
This opportunity is ideal for engineers who thrive in hands-on environments, enjoy solving complex measurements and verification challenges, and want to grow their careers in an innovative, collaborative, and forward leaning organization. You will be part of global R&D network in chosen area of interest with access to Ericsson's leading technology
You will be directly involved in the development of Ericsson's next generation of radio network products, contributing to both system design understanding and end-to-end performance validation.
If you are motivated by technical depth, problem-solving, and cross-functional teamwork-and you want to be part of a company building the future of radio technology-this is the role for you
