About Lynk:
Lynk is the only patented, proven, and commercially-operational satellite-direct-to-standard-phone (sat2phone) system in the world. We 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.
Job Summary:As an LTE / 5G Modem Engineer at Lynk, you will design and plan wireless radio communications systems, including radio propagation modeling and prediction, interference analysis, frequency coordination. Additionally, you will design and develop the DSP software for LTE / 5G, estimate Doppler and propagation delays, create algorithms to process, manage and analyze link budgets and implement compensation algorithms at LTE / 5G Air interface and physical layer.
If you enjoy the challenge of wearing many hats and have a track record of creative thinking to solve unconventional problems, then we look forward to meeting you!
Core Responsibilities:As an LTE / 5G Modem Systems Engineer your core responsibilities are as follows.
- Analyze link budget of LTE / 5G system between satellite and UEs
- Design physical layer receiver for the LTE eNodeB / 5G gNodeB on satellite
- Implementation of baseband modems on software defined radio platforms
- A master’s degree in engineering with 3 – 5 years of related experience required.
- In-depth knowledge of wireless communication systems (OFDM/MIMO, etc.).
- Experience in physical layer algorithm design, algorithm validation, feature bring up, and commercialization.
- Strong knowledge in LTE and 5G standards, including PHY, MAC, and RRC specifications.
- Strong knowledge of software defined radios and their implementation.
- Familiarity with existing telecommunications software stacks (e.g., GSM, LTE, 5G ).
- Hands-on experience on lab testing & characterization.
- Deep understanding of communication theory & 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 or Python and/or C/C++ for algorithm development, modeling, and simulation.
- Experience using test equipment like signal generators, spectrum analyzers, etc.
