RF/Electrical Engineer
About Lynk
Lynk invented satellite direct-to-device (D2D) technology and holds the world's only commercial FCC license for a D2D system. The service enables mobile network operators' subscribers to send and receive text messages via space on standard unmodified mobile devices. Lynk has regulatory approval in over 30 countries and operates under 40+ commercial MNO contracts covering approximately 50 countries, with live deployments on all seven continents.
The Role
As RF/Electrical Engineer, you will design, analyse, optimise and enhance the nanosatellite communications payload and future constellation network. You will work across RF, electrical, mechanical and software domains in a small, hands-on team.
Core Responsibilities
- Support design of spacecraft payload hardware including single-board computers, software-defined radios, FPGAs, SoCs, processors, LNAs, filters and amplifiers
- Select and design nanosatellite antenna technologies
- Develop link budget analyses, simulations, traffic and capacity analysis, RF system design, coverage and frequency planning
- Support payload integration, testing and delivery to launch partners
- Design and plan payload testing configurations for ground and in-orbit communications performance validation
- Interface with Systems Engineering to inform constellation and network architecture based on RF performance
- Perform bench-level mechatronics work including testing, integration, assembly, programming and prototyping
- Conduct software-based systems engineering analysis
- Develop and maintain technical documentation for payload design
- Work independently and collaboratively within the team
Required Qualifications
- Bachelor's degree or higher in RF or Electrical Engineering
- Experience developing space payload hardware and software, preferably communications systems
- Hands-on experience with software-defined radios, antennas, FPGAs, GPUs, CPUs, SoCs and single-board computers
- Programming proficiency in C++, C, Python, MATLAB or similar languages
- Experience working with Linux-based systems
Desired Skills
- VHDL or Verilog and Altera or Xilinx FPGA experience
- Electrical design software proficiency such as Altium
- Strong RF air interface knowledge and multiple access schemes (TDMA, FDMA, OFDMA, CDMA)
- Hardware and software systems integration experience
- Microcontroller and SDR programming
- Communications and networking protocols (IP, TCP/IP, Ethernet, LTE, GSM, 802.11)
- Proficiency with Linux, Windows and macOS; strong Microsoft Office skills (Excel, Project, PowerPoint, Word)
