Developer - Radio SW Design

Join our Team

About us

Ericsson is launching a new R&D center in Yokohama dedicated to radio hardware and software development. This hub will collaborate with leading Japanese CSPs and local vendors to deliver innovative products for global networks. We are hiring engineers at all experience levels to join our team and help develop advanced 5G/6G radio systems. The center aims to strengthen Ericsson’s ties with Japan’s technology ecosystem and accelerate the delivery of high-performance radio solutions worldwide.

The opportunity

You will join a self-organizing agile team developing and maintaining the software and system architecture for an embedded Radio Unit (SW + HW) in an advanced environment with end-to-end responsibility. This is an opportunity to design embedded Radio SW that will be part of Ericsson’s radios deployed in Japan and globally.

What you will do

• Develop and maintain software for next-generation wireless communication systems (5G/6G), including embedded and AI-related features.
• Work in an agile, cross-functional team and participate in the full product lifecycle: requirements analysis, coding, integration, testing, release and customer delivery.
• Design and implement system architecture, contribute to software system design principles, and develop/optimize complex algorithms.
• Perform software development primarily in C++ within a complex system architecture involving both software and hardware components.
• Create and maintain automated tests (preferably using Java) to ensure quality and efficiency.
• Collaborate with global R&D teams, troubleshoot complex system issues, and contribute beyond your primary area of expertise.

What we're looking for

We welcome candidates with a range of experience. Typical background includes:

• Bachelor’s degree or above in Computer Science, Electronics, Communications, Automation, or related fields (Master’s preferred; outstanding undergraduates welcome).
• Knowledge and experience in embedded or application software development using objective-oriented C++ and Java.
• Experience with Python and Shell scripting is expected, familiarity with SQL scripting is a plus.
• Basic exposure to AI/ML concepts (e.g., CNNs, DNNs, RNNs, or Reinforcement Learning) and tools such as TensorFlow or PyTorch is a plus.
• Exposure to AI coding assistants like Amazon Q (or comparable tools) is a plus.
• Knowledge of Linux/Unix development environments, GCC, GDB, Makefile, and inter-process/thread communication.
• Experience with GIT, Eclipse and VSCode.
• Self-driven, proactive learning and innovative mindset.
• Good communication skills; Able to work in English; Japanese language skills are a welcome advantage
• Candidates who have held technical lead roles or who aspire to technical leadership are encouraged to apply.

What we offer

• Be part of a newly established R&D center that will expand our global radio R&D network.
• Opportunities to collaborate with Japan’s ecosystem — operators, research labs and universities — to create impactful, large-scale systems.
• Work on cutting-edge software for radios that will be deployed globally in 5G/6G networks.
• Opportunities for career growth, including technical leadership and cross-disciplinary roles.
