We are looking for a Senior AI-Driven 4G PHY Software Engineer to join our team and contribute to the architecture, development, and real-time optimization of the LTE Layer 1 (PHY) software stack.
In this role, you will work on complex, high-performance embedded software, developing and optimizing PHY features for carrier-grade Open RAN solutions. You will collaborate closely with MAC, System Engineering, Integration, QA, and Product Management teams.
A key part of the role is leveraging AI-powered tools and agentic software development workflows to accelerate coding, debugging, testing, and delivery
What you will do:
Design, develop, and optimize LTE Layer 1 (PHY) software components.
Take ownership of PHY features throughout the development lifecycle, from design and implementation to testing, integration, and production support.
Investigate complex software issues, perform root cause analysis, and optimize real-time performance.
Contribute to software architecture and technical design decisions.
Collaborate with cross-functional teams, including MAC, System Engineering, Integration, and QA.
Improve software performance, reliability, and maintainability in complex embedded environments.
Apply AI-assisted and agentic development tools to improve coding efficiency, debugging, testing, and development workflows.
Share technical knowledge and contribute to engineering best practices.
What you should have:
4+ years of hands-on software development experience in complex embedded or real-time systems.
Strong programming skills in C/C++.
Experience with multithreaded development on Linux-based embedded systems.
Solid understanding of DSP fundamentals and software performance optimization.
Strong debugging, troubleshooting, and root cause analysis skills.
Hands-on experience using AI-assisted development tools or LLM-based workflows, with a basic understanding of AI concepts and RAG.
Familiarity with Git, CI/CD pipelines, and Agile development practices.
Strong problem-solving skills and ability to work independently and collaboratively.
Nice to have:
Knowledge of wireless physical layer (PHY), preferably LTE/4G, 5G, or other OFDM-based technologies.
Experience with Open RAN (O-RAN), eNodeB/gNodeB, or baseband software development.
Experience with SIMD optimization (AVX, SSE, NEON) on ARM or x86 platforms.
Experience with MATLAB or Python for algorithm development, simulation, or validation.
Experience with cloud-native telecom platforms, containerized environments, or large-scale wireless systems.
Experience mentoring junior engineers or contributing to software architecture decisions.
Education:
Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Telecommunications, or a related technical field.
