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
Lynk is developing cellular-based space payloads and seeks a Wireless Engineer to design and
implement feeder link modems for Lynk’s spacecraft and ground systems. This role involves
developing, implementing, and testing DSP and satellite communication protocols. The ideal
candidate will have a strong background in wireless communication, signal processing, and
software engineering to drive innovation in next-generation satellite-based networks.
Must Have’s

● Deep DSP — filter design, clock recovery, channel estimation, channel coding
● Object Oriented Programming proficiency
● Strong real time DSP software implementation experience (GNURadio preferred)
● Hands-on RF lab — spectrum analyzers, signal generators
● Linux proficiency
Core Responsibilities
● Design and implement digital signal processing (DSP) algorithms and wireless
protocols in the PHY and MAC layers.
● Deliver performant and robust production code targeted to software-defined
radio (SDR) platforms using single-board computers and/or FPGAs.
● Evaluate the performance of algorithms in simulation (e.g., MATLAB, Python)
prior to implementation.
● Validate performance on target hardware using RF lab equipment like spectrum
analyzers and channel simulators, as well as networking tools such as ping and
iperf.
● Develop test automation frameworks and manage CI/CD pipelines to support
unit, integration, and system testing of modems.
● Work with cross-functional teams across RF, electronics, and hardware domains
to integrate, benchmark, and debug payload software and communications
systems.
● Debug production issues in conjunction with the operations team to rapidly
resolve complex software and hardware anomalies in orbit or on the ground.
● Create system performance visualizations to continuously monitor
communication links.
● Perform link budget analysis for satellite communication links and evaluate the
selection of spacecraft radios and ground station products.
Qualifications/ Good to have
