The role involves reviewing designs and technical implementations, collaborating with cross-functional engineering teams, and mentoring engineers in PHY development. It is suited to an experienced engineer with a relevant bachelor’s degree and a background in telecommunications, electronics, communications, computer science, or electrical and electronics engineering.

Key Responsibilities

• Develop NR physical-layer software and implement 5G and 6G features, delivering PHY capabilities aligned with wireless system requirements and relevant 3GPP standards.
• Build and refine PHY algorithms using C++, and prototype signal-processing approaches in MATLAB to assess their suitability for physical-layer software.
• Validate PHY functionality with Python-based work and analyze wireless system performance metrics to identify behavior, assess results, and inform engineering decisions.
• Integrate PHY components with broader systems, coordinating technical interfaces and resolving implementation issues in collaboration with cross-functional engineering teams.
• Review designs and technical implementations, providing clear technical feedback that supports sound engineering decisions and reliable physical-layer development.
• Mentor engineers on PHY development, sharing domain knowledge and supporting their ability to deliver NR physical-layer software and features.
• Demonstrated NR PHY development capability, including experience developing physical-layer software and implementing wireless features for 5G systems.
• Strong C++ skills for building PHY algorithms, with an ability to translate physical-layer concepts into robust software implementations.
• Practical MATLAB experience prototyping signal-processing approaches and evaluating algorithm behavior in wireless communications contexts.
• Python capability for validating PHY functionality, examining results, and supporting repeatable engineering analysis of physical-layer implementations.
• Knowledge of wireless communications, physical-layer principles, and signal processing, with the ability to analyze wireless system performance metrics.
• Familiarity with 3GPP standards and their relevance to implementing and reviewing NR physical-layer features and technical designs.
• Ability to integrate PHY components with systems, collaborate across engineering disciplines, review technical implementations, and provide technical leadership or mentoring.

Additional Plus

• Experience contributing to 6G wireless communications or feature development, extending practical NR PHY expertise toward emerging physical-layer requirements.
• A Bachelor of Technology in Electronics and Communication Engineering, Computer Science, or Electrical and Electronics Engineering supports the role’s engineering foundation.
• Experience in telecommunications or related electrical and electronics industries can provide useful context for wireless systems and PHY development.

What You’ll Bring

• At least six and up to ten years of relevant professional experience, bringing senior-level capability in NR PHY development and wireless physical-layer software.
• A Bachelor of Technology in Electronics and Communication Engineering, Computer Science, or Electrical and Electronics Engineering, with relevant specialization in NR PHY, 5G and 6G wireless communications, or physical-layer software.
• Strong practical command of C++, MATLAB, and Python for algorithm development, signal-processing prototyping, and PHY validation, alongside knowledge of wireless communications and 3GPP standards.
