About the Role

seeking a Senior DSP Engineer to lead the development of a next-generation software-defined radio (SDR) platform. This is a high-impact, ground-up engineering effort focused on building advanced modem and air interface capabilities using digital signal processing (DSP).

The hardware foundation is in place, what s needed is a DSP expert who can architect and implement the software layer that drives radio performance, spectrum manipulation, and signal conversion.

Key Responsibilities

• Design and implement DSP algorithms for modem and air interface functionality
• Translate analog signal inputs into actionable digital data through advanced mathematical modeling
• Develop and optimize software for SDR platforms, focusing on spectrum efficiency and protocol compliance
• Conduct statistical analysis and modeling using tools like MATLAB
• Collaborate with RF engineers to ensure seamless integration between hardware and software
• Support testing, validation, and refinement of signal processing components

Required Skills & Experience

• 8+ years of experience in DSP engineering, preferably in wireless communications or SDR
• Strong background in air interface protocols, spectrum analysis, and signal conversion
• Hands-on experience with Blackfin DSP architecture
• Familiarity with 900 MHz RF protocols and spectrum usage
• Proficiency in MATLAB for statistical modeling and algorithm development
• Solid understanding of analog-to-digital conversion and real-time signal processing
• Experience working in small, agile engineering teams

Preferred Qualifications

• Advanced degree (MS or PhD) in Electrical Engineering, Signal Processing, or related field
• Experience in multi-year product development cycles from concept to deployment
• Knowledge of embedded systems and RF hardware integration
