Job Description

At Array Labs, we are building the world’s most advanced radar imaging satellites to produce an accurate, continuously updated 3D map of the Earth, providing governments and commercial organizations with critical insights into the physical world.

We design and build our satellites end-to-end, from on-orbit hardware to ground software and data processing, achieving system performance not possible with conventional satellite systems.

We are seeking a Signal Processing Engineer to join our team and build the core algorithms that make this transformation possible. This is a unique opportunity to have a foundational impact on a first-of-its-kind system.

As part of our quickly growing engineering team, you will play a critical role in the design of the world’s most advanced radar satellite constellation—one that will significantly improve humanity’s ability to rapidly and comprehensively understand our changing planet.

Responsibilities:

Design, model, and implement novel digital signal processing (DSP) algorithms for our next-generation radar systems.

Focus on critical areas such as pulse compression, Doppler processing, interference mitigation, and advanced filtering techniques to maximize signal quality.

Collaborate closely with RF, FPGA, and software engineers to ensure algorithms are robust, efficient, and implementable in a real-time environment.

Develop high-fidelity simulations in MATLAB or Python to validate algorithm performance against theoretical limits and system requirements.

Analyze and characterize system performance using both simulated and real-world data, paying close attention to metrics like Signal-to-Noise Ratio (SNR), resolution, and ambiguity functions.

Stay current with the latest advancements in signal processing and radar technology to continuously innovate and improve our capabilities.

Basic Qualifications:

BS or MS in Electrical Engineering, Computer Science, Physics, or a related technical field.

3+ years of hands-on experience in digital signal processing.

Demonstrated expertise in Digital Signal Processing (DSP) fundamentals (e.g., Fourier analysis, digital filter design, sampling theory, estimation theory).

Proficiency in MATLAB or Python (with libraries like NumPy, SciPy) for algorithm development, modeling, and simulation.

Preferred Skills and Experience:

PhD in Electrical Engineering, Computer Science, or a related field with a focus on signal processing.

A strong background in optimal and adaptive filter design (e.g., Wiener, Kalman), statistical signal processing

Familiarity with radar signal processing concepts (e.g., matched filtering, stretch processing, Synthetic Aperture Radar (SAR) imaging).

Experience with implementing computationally intensive algorithms in C++ or on hardware platforms (FPGA, GPU).

Experience with version control systems like Git and modern software development practices.

A creative and analytical mindset, with a proven ability to solve complex, open-ended problems from first principles.

ITAR Requirements:

To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
