Job Summary

Own end-to-end RF and signal-processing development across DSP, PHY, and system integration for resilient communications in contested environments, leading algorithm design, prototyping, testing, and performance evaluation across 5G/6G, SATCOM, and C3/C4ISR workloads.

  • Lead end-to-end RF/BB algorithm development and testing
  • Drive integration of SDR tools and ML-based optimization

Job Description

Responsibilities

  • Develop novel DSP and signal processing algorithms to improve signal detection and classification in congested, contested, and denied environments
  • Design and implement PHY/baseband algorithms (e.g., OFDM, MIMO, beamforming, advanced channel coding) for modern wireless systems
  • Evaluate different MIMO transmission schemes and beamforming approaches for throughput, interference management, and robustness
  • Conduct theoretical analysis to assess the performance of novel geolocation and direction-finding techniques
  • Design and prototype waveforms for challenging channels (e.g., long-haul, beyond-line-of-sight, high-dynamics, and fading environments)
  • Work with advanced wireless and SATCOM technologies (5G/6G, LTE, Wi‑Fi, tactical data links, protected SATCOM, VLF/HF/UHF/EHF systems, beyond-line-of-sight communications)
  • Prototype, modify, and integrate open-source tools to demonstrate new application areas (e.g., GNU Radio, USRP-based SDR testbeds)
  • Apply machine learning and AI techniques to RF and baseband data for tasks such as signal classification, interference mitigation, RF fingerprinting, and adaptive waveform/beamforming optimization
  • Support communications systems development and analysis by designing and analyzing components such as synchronization, forward error correction (LDPC, Turbo, convolutional codes), spread spectrum, medium access control, channel equalization, and interference cancellation
  • Perform system performance analysis and RF laboratory testing (RF front-end characterization, spectrum analysis, over-the-air testing)

Requirements

  • Bachelor’s degree with 2 years of related experience, or equivalent combination of related education and work experience.
  • Experience with simulation and analysis tools such as MATLAB or Python
  • Technical background in at least one of the following areas: detection and estimation theory; waveform design, modulation theory, error control coding, information theory; stochastic processes, propagation, channel estimation and equalization; receiver design, interference cancellation, algorithm development; system performance analysis, RF laboratory testing
  • Ability to obtain and maintain a U.S. Top Secret security clearance
  • Per the U.S. Government’s eligibility requirements for a clearance, U.S Citizenship is required.
  • This position requires a minimum of 4 days a week on-site

Preferred

  • MS or PhD in an engineering discipline with 2+ years of relevant experience
  • Experience with strategic, mission-critical, or national-level command and control communications, C3/C4ISR systems, or protected and hardened communications infrastructures
  • Strong interpersonal and leadership skills, with the ability to lead collaboration across organizations and engineering disciplines
  • Experience developing technical reports, presentations, and/or production-quality code
  • Experience with systems engineering processes for communication systems (e.g., requirements development/review, verification and validation, end-to-end architecture analysis, link budget analysis)
  • Experience with SDR platforms and RF test equipment (e.g., USRP, spectrum analyzers, vector signal analyzers, channel emulators)
  • Existing DoD Secret or Top Secret clearance
  • This requisition requires the candidate to have a minimum of the following clearance(s): None
  • This requisition requires the hired candidate to have or obtain, within one year from the date of hire, the following clearance(s): Top Secret
