Job summary

Blue Origin is seeking a senior engineer to develop and optimize communications systems and modem algorithms for the TeraWave network. You will collaborate across ASIC, RF, firmware, and system teams from algorithm development and simulation through implementation and validation.

Responsibilities include modeling channels and impairments, evaluating tradeoffs, and supporting pre‑silicon verification and post‑silicon validation.

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field.
• 10+ years of experience in communications systems, modem design, or DSP.
• 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.
• US citizen or permanent resident or eligible to work in the U.S.

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.
