Wireless Engineer - Cellular

Lynk is the inventor of satellite direct to device or D2D technology, and has the world’s only commercial license from the FCC to operate a commercial D2D system. Today, Lynk allows mobile network operators' subscribers to send and receive text messages to and from space via standard unmodified, mobile devices. Lynk’s service has been tested and proven on all seven continents, has regulatory approvals in more than 30 countries, and is currently being deployed commercially based on more than 40 MNO commercial service contracts covering approximately 50 countries.

Our technology will enable all 8 billion people on the planet to stay connected with the existing standard phone in their pocket. Everywhere. No matter what.

By joining Lynk, you will have the opportunity to directly touch the lives of billions. Your mission will be to bring mobile broadband to billions, pull hundreds of millions out of poverty, and save countless lives.

Lynk is developing cellular-based space payloads and seeks a Wireless Engineer to design and implement air interfaces for Lynk’s satellite-direct-to-phone services. This role involves developing DSP, optimizing the physical layer procedures, and implementing custom resource scheduling algorithms. The ideal candidate will have a strong background in wireless communications, signal processing, and RAN development to drive innovation in next-generation satellite-based mobile networks.

As a Wireless Engineer, your core responsibilities are as follows

• →

  Design and implement physical - PHY and medium access control - MAC layer algorithms and procedures for satellite communication links.

• →

  Develop baseband modems on software defined radio - SDR platforms.

• →

  Evaluate the performance of algorithms in simulation and on the target platform.

• →

  Develop test software and drivers to support unit, integration, and system testing of all base station software functions.

• →

  Perform link budget analysis of LTE and 5G system between satellite and UEs.

• →

  Work with other team members to benchmark payload software applications.

• A Master’s degree or higher in Electrical Engineering, Computer Science, or related field.

• Deep understanding of communication theory and signal processing related algorithms design, such as filter design, clock recovery, signal detection, channel estimation and equalization, channel coding, MIMO.

• Strong knowledge of software defined radios - SDRs and their implementation.

• Strong knowledge of the 3GPP standards, including LTE and 5G PHY, MAC, and RRC specifications.

• Hands-on experience in lab testing & characterization.

• Experience with MATLAB, Python, C or C++ for algorithm development, modeling, and simulation.

• Experience using test equipment like signal generators, spectrum analyzers, etc.

• Experience with implementing DSP algorithms in HDL, such as SystemVerilog, VHDL is a plus.
