Design & Development
Develop and implement sophisticated physical layer algorithms tailored for DSP-based wireless modems.
Lead the design and coding of Layer 1 modem software, with a strong emphasis on 5G PHY implementation and performance optimization.
Utilize your in-depth knowledge of DSP-based modems, such as NXP Layerscape modems, to integrate and enhance modem functionalities in software
System Integration & Testing
Collaborate with cross-functional teams to ensure seamless integration of modem software with firmware and other system components.
Develop comprehensive test strategies, simulate real-world scenarios, and validate performance under diverse conditions.
Identify performance bottlenecks and deploy innovative debugging and optimization techniques to enhance system efficiency.
Analysis & Reporting
Conduct detailed performance analyses, including link budget assessments, throughput, latency, and error rate evaluations.
Document design methodologies, test results, and system enhancements to support continuous improvement and knowledge sharing.
Provide technical support during system integration, design reviews, and field trials.

What you bring to this role:

Bachelor’s or Master’s degree in Electrical Engineering, Telecommunications, or a related field.
Demonstrable experience in wireless modem design, including DSP-based implementations and 5G PHY development.
Extensive hands-on expertise with Layer 1 modem software development and integration.
Solid understanding of digital signal processing, communication theory, and wireless standards (e.g., 4G, 5G, 5G NR, LTE).
Proficiency in programming/scripting languages such as C/C++, Python, or MATLAB.
Excellent problem-solving skills, with a proven track record of troubleshooting and optimizing complex communication systems.
Strong collaboration and communication skills, essential for working within cross-functional teams.

Bonus points for the following:

Experience with modern coding techniques such as LDPC, Turbo Codes, or Polar Codes.
Prior exposure to simulation tools (e.g., MATLAB, Simulink) and real-time system testing.
Familiarity with software-defined radio (SDR) platforms and related development tools.
Background in wearable technology or emerging IoT applications.
