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. 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

Skills

• Advanced degree (MS/PhD) in Electrical Engineering, Computer Engineering, or related field
• Experience in full ASIC lifecycle (architecture, design, simulation, verification, validation, integration & test)
• Experience taking DSP algorithms from MATLAB/Python reference models into real-time C/C++, FPGA, DSP, or ASIC implementations
• Experience with Software-Defined Radio architectures, ADC/DAC, and/or DSPs
• Familiarity with multirate digital signal processing techniques
• Experience with real-time embedded DSP implementation, profiling, optimization, and hardware/software partitioning
• Experience with pre-silicon verification, hardware bring-up, and lab correlation/debug
• Experience mentoring junior engineers

Benefits
