About Northwood

Northwood is a space infrastructure company building a global network of phased-array ground stations that enable real-time, reliable communication for satellite missions including national security, global connectivity, and disaster response.

The Role

As a Senior RF & Antenna Systems Engineer, you will define and evaluate phased-array RF architectures for satellite ground-station systems. You will translate mission and link requirements into antenna, aperture, beamforming, RF front-end, calibration, and tracking specifications. You will evaluate how those choices affect end-to-end communications performance, working across antenna, RF, DSP, digital, mechanical, manufacturing, software, and operations teams.

This role sits at the intersection of phased arrays, RF systems, SATCOM links, and physical-layer communications. The ideal candidate has deep experience in phased-array or antenna systems and can connect gain, scan loss, polarization, sidelobes, noise, linearity, phase noise, and calibration to EVM, acquisition, BER, throughput, and link availability.

Responsibilities

  • Define phased-array antenna and RF-system architectures for satellite communication ground stations.
  • Translate mission, coverage, link-availability, waveform, throughput, and regulatory requirements into aperture, RF front-end, beamforming, calibration, pointing, and tracking specifications.
  • Develop and maintain end-to-end SATCOM link budgets incorporating measured aperture and RF-chain performance.
  • Analyze analog, hybrid, and digital beamforming approaches in collaboration with RF and digital implementation teams.
  • Determine how antenna and RF impairments affect communications performance, including EVM, carrier acquisition, BER/BLER, throughput, spectral compliance, and link availability.
  • Analyze RF lineups and performance budgets for gain, noise figure, dynamic range, linearity, compression, intermodulation, phase noise, frequency stability, filtering, and isolation.
  • Build Python, MATLAB, or similar models combining array behavior, measured RF performance, propagation, and modem-level metrics.
  • Lead cross-functional investigations of degraded G/T, EIRP, link margin, EVM, acquisition, tracking, BER, throughput, or spectral performance.
  • Support regulatory submissions, spectrum coordination, partner interface reviews, system acceptance, and operational deployment.

Basic Qualifications

  • Bachelor's or advanced degree in Electrical Engineering, Communications Engineering, Applied Physics, or a related discipline.
  • 2+ years of experience with phased arrays, antenna systems, RF communication systems, or SATCOM terminals.
  • Experience with communication-link analysis, including EIRP, G/T, C/N0, Eb/N0, link margin, atmospheric loss, and interference.
  • Understanding of digital communications sufficient to relate RF performance to modulation-dependent EVM, acquisition, BER, throughput, and spectral performance.
  • Experience defining or evaluating RF lineups, including noise figure, gain, linearity, dynamic range, phase noise, filtering, and isolation.
  • Hands-on experience with RF measurements and integrated system debugging using equipment such as vector network analyzers, spectrum analyzers, signal generators, noise sources, and vector signal analyzers.

Preferred Qualifications

  • Familiarity with SATCOM waveforms and standards such as DVB-S2/S2X, CCSDS, or equivalent modem architectures.
  • Experience analyzing modulation-dependent EVM, BER/BLER, adjacent-channel leakage, spectral regrowth, amplifier backoff, and link degradation.
  • Experience with SDR-integrated RF systems or collaboration with FPGA, DSP, modem, and embedded-software teams.
  • Experience with HFSS, CST, or comparable full-wave electromagnetic tools.
  • Familiarity with radar, sensing, 5G NR, 802.11ad/ay, MIMO, multi-beam systems, or electronic-warfare systems where the experience transfers to array and RF-system architecture.
