Project Kuiper is an initiative to launch a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband connectivity to unserved and underserved communities around the world. As a Senior Modem Software Design Engineer you will be a part of the team participating in the definition as well as implementation of Project Kuiper’s broadband wireless communication software architecture. You will participate in all phases of physical layer software development, from architecture design, through requirements, implementation, test, and operational support. This is a unique opportunity to innovate and define novel wireless technology with few legacy constraints. The team develops the communication system of Kuiper and validates overall performance within key metrics such as throughput, latency, system availability, packet loss etc.Export Control Requirement
Key job responsibilities
Design the embedded software architecture operating the Physical Layer (L1) Modem across multiple nodes within the Kuiper network
- Develop embedded software in assembly, C, and C++ in a real-time operating system environment for broadband satellite communication modem systems.
- Support system bring-ups and end-to-end testing using lab equipment such as Vector Signal Generators and Analyzers, Packet Generators, Channel Emulators. Contribute development-test bring up procedures with Linux, Python, bash scripting etc.
- Support operations using telemetry to validate link performance over key indicators such as throughput, latency, etc.

- MS degree in Computer Science or Electrical Engineering or similar.
- 7+ years of non-internship professional embedded software development with real time constraint experience.
- Experience should include code development methodologies, debugging, version control, and code maintenance.
- Experience with software defined radios (SDRs) and embedded programming in C/C++ and VHDL/Verilog is a plus.

- PhD in Computer Science or Electrical Engineering
- Experience in multiple access wireless communications systems such as 5G, WiFi, or other OFDM systems.
- Knowledge of ethernet protocols such as IP, UDP, TCP, HTTP and analysis tools such as Wireshark
- Experience in test automation setup and scripting languages such as Python/Perl/Matlab.
- Experience with software defined radios and embedded programming in C/C++ and VHDL/Verilog is a plus.
- Experience with Lab test equipment such as channel emulator, spectrum analyzers and Signal and network traffic generators
- Familiarity with modem system simulation in Matlab or C/C++
- Ideal candidate has a wireless communication systems or digital signal processing background, a passion for building real-world carrier-grade communication systems, and industry experience developing PHY/MAC layer software targeting embedded multicore processors in C/C++
