Strong proficiency in C/C++ and real-time, multi-threaded programming on GPP platforms
Solid understanding of 3GPP 5G NR standards, particularly MAC scheduling and RAN system behavior
Proven experience delivering carrier-grade solutions for Tier-1 operators at large scale, with strong focus on quality, performance, and reliability
Experience in end-to-end RAN system design, including L1/L2 interactions and feature integration
Strong background in performance optimization on multi-core and distributed systems
Experience with cloud-native, containerized, and virtualized network functions
Familiarity with O-RAN architecture and openness to open RAN ecosystems
Exposure to or strong interest in AI/ML applications in telecom, especially in scheduling or RAN optimization
Demonstrated ability to contribute to or support major operator deployments in complex environments
Ability to lead features, subsystems, or architectural areas with increasing ownership and technical responsibility
Proven or emerging technical leadership, with experience influencing architecture and technical direction
Experience mentoring engineers and contributing to team or organizational growth
Experience integrating performance, scalability, and operability into system design from the ground up
Experience or interest in contributing to advanced RAN innovation, internal technology strategy, or industry forums (e.g., 3GPP)
Demonstrated potential or readiness to grow into a Principal Architect role, or proven success operating at that level

Responsibilities
