Senior Digital Signal Processing Engineer

Impulse Space is developing advanced digital signal-processing technologies for resilient terrestrial and spaceborne communications, position/navigation/timing (PNT), RF sensing, and radar systems. We are seeking a proactive Senior Digital Signal Processing Engineer to lead DSP architecture and algorithm development for space and ground applications.

You will partner with systems, RF/antenna, ASIC/FPGA, firmware, software, hardware, validation, and mission teams to translate communication and sensing needs into implementable, verifiable systems for demanding operational environments.

Responsibilities

• Lead system-level DSP decisions spanning algorithms, modem architecture, firmware/software, ASIC/FPGA implementation, and RF hardware for communications, PNT, radar, and RF sensing systems.
• Develop signal-processing solutions for digital beamforming, multi-user/MIMO systems, synchronization, estimation, detection, tracking, interference mitigation, and adaptive communications or sensing.
• Model and evaluate end-to-end system and link performance using floating- and fixed-point simulations of modem, beamforming, PNT, radar, and sensor-processing chains.
• Translate algorithms into hardware-realizable, bit- and cycle-accurate implementations in partnership with ASIC/FPGA, RF, firmware, and software engineers.
• Define and maintain system requirements, interfaces, verification plans, test procedures, and test vectors.
• Analyze link budgets, channel and hardware impairments, interference, multiple-access performance, dynamic range, quantization, and other system-level tradeoffs.

Minimum Qualifications

• B.S. in electrical engineering, computer engineering, computer science, physics, mathematics, or a related STEM field.
• 5+ years of experience in DSP, RF/wireless systems, modem development, radar or sensor processing, or system-level modeling.
• Demonstrated experience developing, simulating, and transitioning algorithms toward fixed-point, firmware, FPGA, or ASIC implementations.

Preferred Skills and Experience

• M.S. or PhD in electrical engineering or a related discipline with an emphasis in communications, signal processing, controls, or RF systems.
• Demonstrated experience with digital beamforming, phased arrays, MIMO or massive MIMO, modems, PNT, radar, RF sensing, satellite communications, or high-data-rate wireless systems.
• Demonstrated experience with TDMA, CDMA, OFDMA, coding/modulation, link adaptation, channel estimation, equalization, synchronization, detection, and tracking.
• Demonstrated experience modeling multipath, phase noise, group delay, fading, interference, nonlinear distortion, quantization, and oscillator effects.
• Proficiency in MATLAB, Python, and/or C/C++; GNU Radio or other SDR experience is a plus.
• Demonstrated experience with Git and cross-functional engineering tools such as Jira, Confluence, Bitbucket, or equivalent.
