About Lynk Global Lynk Global 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. Job Summary As an Electrical Engineer at Lynk, you will function in many roles to use and expand your knowledge of electronics and PCB design. You will be responsible for analysis, schematic capture, and layout of complex mixed signal PCBAs intended for use in Lynk designed spacecraft. These boards often contain some combination of high pincount FPGAs, SoCs, and ADC/DACs, and you will be responsible for collaborating with other hardware and firmware engineers to oversee board bring-up. Candidates should be comfortable working in both a design and laboratory environment, and have experience designing systems intended for harsh environments. Core Responsibilities Hardware Architecture: Design multi-layer mixed signal PCBs featuring high-pin-count FPGAs and ADC/DACs. High-Speed Design: Implement high-speed interfaces such as PCIe Gen 4/5, DDR memory interfaces, and 10/40/100G Ethernet. Ruggedization: Design for harsh environments (thermal cycles, mechanical shock, vibration, etc.). Power Integrity: Develop complex power trees capable of delivering high current at low voltages. Signal Integrity (SI) & Power Integrity (PI): Perform pre- and post-layout simulations to ensure timing closure and link reliability. Firmware: Collaborate closely with RTL teams to define pinouts, bank voltages, and clocking architectures that optimize PCB routing. Qualifications A bachelor’s degree or higher in Electrical or Computer Engineering 10+ years experience designing complex mixed signal PCBs for harsh environments with high pincount components (FPGAs, SoCs, etc.) Experience with board bring-up and testing. Experience with 1 or more PCB design tool Altium is a preferred Understanding of FPGA hardware requirements, including power distribution, high speed SERDES routing, memory interfaces, etc. Strong grasp of Design for Manufacturing (DFM) and Design for Test (DFT) in low-to-medium volume, high-complexity production. Basic knowledge of RTL/firmware development ITAR Requirements: To comply with U.S. Government export control regulations (ITAR), applicants must be one of the following: (i) a U.S. citizen or national, (ii) a lawful permanent resident (green card holder), (iii) a refugee under 8 U.S.C. § 1157, or (iv) an asylee under 8 U.S.C. § 1158. Individuals who do not meet these criteria must be eligible to obtain the necessary authorizations from the U.S. Department of State. For more information, please refer to the ITAR guidelines.
