Wireless Firmware Engineer (Direct To Cell)
Jobs via Dice, Sunnyvale, California, United States, 94087
Overview
Wireless Firmware Engineer (Direct To Cell). The direct-to-cell program aims to provide global cellular connectivity from space. The role involves developing wireless signal processing algorithms, optimized software for satellites and ground stations, debugging, and producing production software. Collaborate with wireless systems engineers and protocol firmware engineers to accelerate wireless PHY development. Responsibilities
Design and implement physical layer (PHY) algorithms for satellite-based 4G/5G (LTE/NR) eNodeB/gNodeB. Develop optimized signal processing algorithms for resource-constrained CPUs. Model and simulate system performance, including modem performance. Design, implement, test, maintain, and document the wireless PHY and MAC layers of the protocol stack. Identify and debug complex performance issues across the PHY and MAC layers. Participate in architecture, design, and code reviews; contribute to system dimensioning and algorithm design for next-generation hardware. Basic Qualifications
Bachelor's degree in computer science, computer engineering, electrical engineering or a STEM discipline. 1+ year of experience in wireless signal processing, wireless communications, modem systems design, wireless systems engineering, DSP, or physical layer processing (L1). 1+ year of C/C++ or MATLAB coding experience. Preferred Skills and Experience
Familiarity with 3GPP 4G/5G (LTE/NR) physical layer design or other broadband OFDM waveforms. Familiarity with forward error correction concepts. Basic familiarity with MAC layer (L2). Development and optimization of complex signal processing algorithms (fixed and floating point). Familiarity with Linux, Git, and Python. SDR (software defined radio) experience. Experience supporting products through the full release cycle including commercial deployment. Strong debugging and performance optimization skills; solid engineering fundamentals. Excellent verbal and written communication skills; ability to work in a dynamic environment. Additional Requirements
Must be willing to work extended hours as needed. Compensation and Benefits
Pay ranges vary by level and are determined based on job-related knowledge, education, and experience. Base salary and total rewards may include stock, bonuses, and other incentives. Benefits include medical, vision, dental, 401(k), disability and life insurance, paid leave, vacation, holidays, and sick leave. ITAR Requirements
