Job Summary

Lynk is developing cellularbased space payloads and seeks an LTE and 5G RAN Engineer to design and develop Radio Access Network RAN infrastructure for satellite direct to device services. This role involves developing DSP for LTE and 5G optimizing the physical layer algorithms 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 nextgeneration satellitebased mobile networks.

Core Responsibilities

As an LTE and 5G RAN Engineer your core responsibilities are as follows

• Design and implement physical layer PHY transceiver algorithms and medium access control MAC layer procedures for satellitedirecttophone links based on LTE and 5G NR.

• Develop baseband modems on software defined radio SDR platforms.

• Evaluate the performance of the cellular base station 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.

Qualifications

• A Masters degree in Engineering with 3 to 5 years of related experience is required.

• Indepth knowledge of wireless communication systems such as OFDM MIMO etc.

• Experience in physical layer algorithm design algorithm validation feature bringup and commercialization.

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

• Strong knowledge of software defined radios and their implementation.

• Familiarity with existing telecommunications software stacks such as LTE 5G NR implementations.

• Handson experience in lab testing and characterization.

• Deep understanding of communication theory and signal processing related algorithms design such as timing recovery signal estimation and detection RF impairment estimation and correction channel modeling and estimation Doppler compensation techniques etc.

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

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