Junior L1 Software Developer

Grow with us Location: Ottawa, Ontario, Canada – Ericsson will not provide immigration support at this time. Approximately 40% of the world’s mobile traffic is carried through an Ericsson network. Our 5G Radio Access Network (RAN) solutions already connect billions of devices, and we are shaping the evolution toward 6G.

Within this context, our L1 Software Development team in RCE RAN Performance designs and implements the Physical Layer baseband functions – the signal‑processing engine at the heart of 5G. Mission Develop high‑quality L1 features that grow our customers’ businesses and improve network performance. Secure the product’s future through cutting‑edge technology, cloud‑native architectures, and continuous innovation.

What you will do Design, develop, and test L1 software components on Ericsson’s 5G processing platform and related cloud/COTS environments. Implement and enhance Physical Layer baseband features across a range of deployment scenarios and frequency bands defined by 3GPP. Perform continuous analysis, clarify requirements, and contribute to technical solutions that balance performance, scalability, and reliability.

Work in both manual and highly automated environments to integrate new software modules and algorithms, and to troubleshoot complex issues. Apply real‑time software development practices and knowledge of wireless communication protocols (e.g., NR/5G, LTE, WCDMA, WLAN). Participate in code reviews, inspections, and design discussions to help maintain high software quality standards.

Develop and maintain test coverage to ensure new changes do not degrade existing functionality. Explore cloud‑native platforms and learn how to optimize L1 software for containerized and virtualized environments. Use AI/ML tools and techniques where appropriate to accelerate development, improve performance, or enable intelligent automation.

Contribute to a modern, agile way of working, including sprint planning, estimation, and continuous improvement activities. Document system analysis, software designs, and test plans in line with internal standards.
