What are the responsibilities and job description for the Principal RF/Electrical Engineer position at Lynk?
About Lynk
Lynk is the inventor of satellite direct to standard phone technology or sat2phone and has the world’s only commercial license from the FCC to operate a commercial sat2phone 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.
Job Summary
As a Principal RF/Electrical Engineer at Lynk, you will be responsible for wearing many hats in the world of radio frequencies, electronics, hardware, and software. You will be responsible for the analysis, design, implementation, optimization, and enhancement of our satellite communications systems (and, ultimately, the future constellation network, including inter-satellite and multi-orbit links). Some work products will include link budgets analyses, system dimensioning for coverage and capacity (including traffic analysis and simulation), initial system design and dimensioning, coverage planning, frequency planning, interference analysis and mitigation techniques. This engineer will also be responsible for supporting the iterative design and testing of our satellite communications systems hardware/electronics and software. This will include working with software defined radios, single-board computers, FPGAs, SoCs, processors, LNAs, and filters – you will also be involved in our payload antenna selection and design. While playing with all this hardware on a bench, you’ll probably need to pick up a soldering gun, use a spectrum analyzer, assemble circuits on a breadboard, and/or configure an RF channel simulator.
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
The RF/Electrical Engineer will be responsible for straddling engineering work in the domains of RF, electrical, mechanical, and software engineering.
