Simulation Software Engineer, RF & DSP - Terawave

Blue Origin • Cupertino, CA

3d

About The Position

Blue Origin is seeking a talented Software Engineer to join the Silicon System team. In this role, you will work closely with RF system and DSP engineers to optimize simulation models for silicon-based components and phased array antenna systems. Your work will directly impact the performance, accuracy, and scalability of our simulation infrastructure. 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.

Requirements

• 3+ years of experience in software engineering with MATLAB, Python, and C++.
• Demonstrated experience profiling and optimizing computational code for speed and memory efficiency.
• Strong understanding of data structures, algorithms, and memory management.
• Familiarity with numerical methods and scientific computing.
• Experience with version control systems (Git).
• Strong analytical and problem-solving skills.

Nice To Haves

• Master's or Ph.D. in Electrical Engineering, Applied Math, or related field.
• Experience with phased array antenna systems, RF simulation, or electromagnetic modeling.
• Knowledge of silicon RFIC and DSP design or related hardware simulation.
• Experience with MATLAB MEX files and MATLAB/C++ co-development.
• Experience with parallel and distributed computing frameworks.
• Background in signal processing or beamforming algorithms.
• Experience working in aerospace, defense, or satellite communications environments.

Responsibilities

• Optimize existing MATLAB, Python, and C++ simulation models for phased array antenna systems to reduce memory footprint and simulation runtime.
