## About the Role

BS in Electrical Engineering, Computer Engineering, or a related field, with 10+ years of relevant industry experience.

Strong knowledge of cellular communication standards and associated feature sets: 6G (emerging), 5G NR, 4G LTE - particularly RAN1 3GPP.

Proficiency in MATLAB, C/C++, and/or Python for algorithm development, fixed/floating-point modeling, and link-level simulation.

Experience leveraging Generative AI and LLM-based tools to accelerate engineering workflows - e.g., algorithm prototyping, code generation, simulation analysis, or technical documentation

Preferred Qualifications

Experience in Layer-1/2 control design of cellular systems.

Experience in low-power algorithm design for power-constrained mobile platforms.

Experience in end-to-end timeline analysis for latency-critical PHY processing chains.

Strong mathematical foundations: linear algebra, stochastic processes, detection & estimation theory.

Familiarity with 3GPP standardization processes, RAN2, RAN4 topics and emerging 6G study items (e.g., AI/ML for air interface, joint communication and sensing, reconfigurable intelligent surfaces).

Track record of published research or patents in wireless communications is a plus.

## Description

As a Cellular Systems Engineer, you will own the end-to-end lifecycle of cellular modem systems - from feature set and capability definition that improve cellular user experience of our products to concept work, algorithm design through silicon bring-up and productization. In this role you are expected to Collaborate cross-functionally with eco-system teams, SoC, PHY, PHY HW, PHY FW, and L1 SW teams to ensure end-to-end system requirements are met across the full stack.
