Job summary

Blue Origin seeks a Sr Comms System and Modem Engineer for the Terawave project in California. The role focuses on developing and optimizing high-throughput satellite communication systems and sequencing modem algorithms across DSP, PHY, and system-level modeling.

You will collaborate with ASIC, RF, firmware, and system teams from algorithm development to implementation and system validation, supporting pre-silicon verification and post-silicon bring-up.

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline.
• 10+ years of experience in communications systems, modem design, signal processing, or DSP algorithm development.
• Strong understanding of digital communications and signal processing fundamentals.
• Hands-on experience developing and simulating communications and DSP algorithms using MATLAB, Python, C/C++, or similar tools.
• Strong understanding of OFDM-based communication systems, including synchronization, channel estimation, equalization, modulation/demodulation, and frequency-domain signal processing.
• Experience developing and evaluating modem/PHY algorithms in end-to-end communication-system simulations.
• Understanding of practical RF and channel impairments and their impact on modem performance.
• Ability to work across modem, RF, ASIC, firmware, and system engineering teams.

Responsibilities

• Develop and optimize PHY, modem, and DSP algorithms for high-throughput satellite communication systems.
• Develop algorithms for synchronization, carrier and sampling frequency offset estimation and compensation, channel estimation, equalization, SNR estimation, modulation/demodulation, and other modem signal-processing functions.
• Develop MATLAB, C/C++, Python, or equivalent system-level models to evaluate modem algorithms and end-to-end communication-system performance.
• Model and analyze communication channels and impairments, including noise, fading, interference, frequency and phase errors, nonlinearities, and RF impairments.
• Evaluate modem architecture and algorithm tradeoffs across performance, complexity, throughput, latency, and implementation.
• Work closely with ASIC, RF, firmware, and system engineering teams to translate modem algorithms into the TeraWave implementation.
• Support pre-silicon verification, prototyping, system integration, and post-silicon validation of modem algorithms.
• Analyze end-to-end system performance and identify opportunities to improve modem and link performance.
• Provide technical guidance and contribute to key modem and communications-system architecture decisions.
