• Implementing and enhancing Physical Layer baseband features across a range of deployment scenarios and frequency bands defined by 3GPP.
• Performing continuous analysis, clarifying requirements, and contributing to technical solutions that balance performance, scalability, and reliability.
• Working in both manual and highly automated environments to integrate new software modules and algorithms, and to troubleshoot complex issues.
• Applying real‑time software development practices and knowledge of wireless communication protocols (for example NR/5G, LTE, WCDMA, WLAN).
• Participating in code reviews, inspections, and design discussions to help maintain high software quality standards.
• Developing and maintaining test coverage to ensure new changes do not degrade existing functionality.
• Exploring cloud‑native platforms and learning how to optimize L1 software for containerized and virtualized environments.
• Using AI/ML tools and techniques where appropriate to accelerate development, improve performance, or enable intelligent automation.
• Contributing to a modern, agile way of working, including sprint planning, estimation, and continuous improvement activities.
• Documenting system analysis, software designs, and test plans in line with internal standards.

The skills you will bring:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, Communications Systems, AI/ML, or a related field.
• 0–4 years of professional experience in a relevant domain.
• Passion for software development and systems programming, with a strong desire to grow into a technical expert in wireless and L1.
• Strong programming skills in C/C++, with a focus on embedded or systems‑level software.
• Familiarity with real‑time or concurrent software development for embedded systems.
• Understanding of wireless communication fundamentals, such as quadrature modulation, channel coding, OFDMA, and receiver theory.
• Interest or experience in developing L1 software for major wireless standards (for example NR, LTE, WCDMA, WiMAX, WLAN).
• Comfort working in a Linux development environment.
• Experience with software configuration and delivery tools such as Git, Gerrit, and Jenkins (or similar).
• Awareness of cloud concepts and platforms, and enthusiasm to learn how to build and optimize cloud‑native solutions.
• Curiosity about how AI and machine learning can be applied to software development and wireless systems.
• Strong analytical and critical‑thinking skills, with a methodical approach to debugging and problem solving.
