Principal DSP Engineer - Terawave
About the role
At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!
Blue Origin is pioneering the future of space-based communications with TeraWave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide. This role will be onsite in either the Bay Area-CA, Austin-TX, or Kent-WA. It is approved for a temporary remote work exception while specific sites are being developed.
Responsibilities
- Develop models and algorithms for the TeraWave Custom Silicon. This includes packet processing, MAC, PHY, and Radio DSP
- Hands-on development and implementation of DSP/PHY algorithms using MATLAB, Python, and C/C++
- Take algorithms from floating-point modeling through fixed-point implementation and bit-accurate verification
- Drive for lowest power consumption and highest performance
- Target your algorithms for FPGA and ASIC implementation, including fixed-point optimization, word-length analysis, and implementation tradeoffs
- Support the ASIC implementation through pre-silicon verification
- Design advanced digital end-to-end communication systems
- Develop and model channel impairment models
- Work collaboratively with ASIC, RFIC, and SW implementation teams
- Work with the application team to bring up prototype pre-silicon platforms and support post-silicon validation of architecture and algorithm performance
- Debug and correlate algorithm performance across system models, RTL/FPGA, and silicon
Requirements
- 10+ years of experience in signal processing or modem design and development
- Bachelor's degree in Electrical Engineering, Computer Engineering, or related technical discipline
- Experience with PHY, DSP, beamforming, RF and/or mixed-signal designs
- Strong hands-on programming experience in MATLAB, Python, and C/C++ for DSP/communications algorithm development
- Experience with floating-point and fixed-point modeling, bit-accurate implementation, and algorithm optimization
- Experience with MATLAB, SystemC, C/C++ or other system-level modeling tools
- Knowledge of DSP and communications systems, filters
