About Northwood Space:

Northwood is on a mission to build a data highway between earth and space and bring the benefits of space to the masses through innovations in space communications technologies. If you like building quickly and seeing your work deployed in locations around the globe with real impact, we want you at Northwood.

Role:

As an RF & Antenna Systems Engineer, you will define and evaluate advanced RF communication and sensing architectures supporting satellite and ground systems. This role sits at the intersection of antenna systems, RF hardware, signal processing, and communications, translating mission requirements into RF system architectures and performance trade studies spanning antennas, RF front ends, and signal processing.

You will collaborate with electrical, RF, mechanical, manufacturing, and software teams to develop antenna systems, adaptive beamforming strategies, and high-performance communication links.

We build real RF apertures and evaluate them as integrated systems operating at global scale.

Responsibilities

• Analyze RF system and communication link performance, deriving top-level specifications for antenna systems, RF front ends, and signal processing architectures

• Evaluate and develop antenna system architectures, including phased arrays and adaptive beamforming strategies

• Model system-level RF, link budgets, and signal processing behavior to guide beamforming architectures, modem implementations, and system trade studies, including measured aperture performance in complex electromagnetic environments

• Design and analyze antenna systems, pointing and tracking strategies, aperture calibration and performance optimization

• Plan and execute integrated system tests focused on physical-layer performance such as G/T, EIRP, link margin, and modem performance metrics

• Investigate RF system and link performance issues through measurement, modeling, and cross-disciplinary debugging

• Work with RF, antenna, DSP, and communications engineers to translate algorithmic concepts into practical RF system implementations

• Support regulatory submissions, link performance analysis, and operational RF system design

Basic Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Applied Physics, or related discipline

• 5+ years experience modeling and analyzing RF systems, antenna systems, or communication links

• Strong foundation in electromagnetics, antenna theory, and RF system design

• Experience with MATLAB, Python, Rust, or similar tools for RF system or signal-processing analysis

• Experience with RF test equipment such as vector network analyzers, spectrum analyzers, and signal generators

Preferred Experience

• Experience with phased arrays, beamforming systems, or advanced antenna architectures

• Strong understanding of beamforming theory, array factor, and electromagnetic propagation

• Experience performing link budget analysis and communication system trade studies

• Familiarity with modem architectures and physical-layer performance metrics

• Familiarity with radar systems, RF sensing systems, or electromagnetic warfare concepts

• Experience in RF lineup design, including amplifier linearity and filter isolation tradeoffs

• Experience analyzing metrics such as BER, EVM, noise figure, and dynamic range

• Experience building analysis tools in Python or similar languages
