About the Job

Requirements

A bachelor's degree in electrical engineering, computer engineering, computer science, physics, mathematics, or a related STEM field.
At least 5 years of experience in digital signal processing, RF/wireless systems, modem development, radar or sensor processing, or system-level modeling.
Demonstrated experience developing and simulating algorithms and transitioning them toward fixed-point, firmware, FPGA, or ASIC implementations.

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.

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.

About the Company

Impulse Space

In-space propulsion and payload mobility

Impulse Space builds in-space mobility services and propulsion to move payloads after launch. Its products include Mira for precise maneuvering and rendezvous, Helios high-energy kick stage, Caravan rideshare to higher-energy orbits, and propulsion lines Saiph, Deneb, and Rigel. These tools act as in-space tugs and stages to push, dock, and deploy payloads in orbit. Led by SpaceX veteran Tom Mueller, Impulse Space uses flight-proven hardware and a growing network of facilities to make reaching higher-energy orbits faster and cheaper, expanding access for customers.
