Overview
Due to federal contracting regulations, US Citizens Only.
Early-career RF engineer supporting development, integration, and validation of RF systems across modeling & simulation, software-defined radio (SDR) platforms, and live RF test environments. Work spans digital signal processing, waveform generation, RF analysis, and integration into high-performance simulation frameworks and real-world emitter systems.
Responsibilities
- Support development and testing of RF waveforms (e.g., QPSK, BFSK/FSK, DSSS/CDMA) in SDR environments (GNU Radio or equivalent)
- Assist in RF system integration across simulation and hardware environments, including signal generation, capture, and analysis
- Conduct RF performance analysis including EVM, SNR, BER, spectral occupancy, and interference effects
- Implement and test DSP chains including filtering, modulation/demodulation, synchronization, and channel effects
- Support modeling and simulation efforts related to RF propagation, electronic warfare (EW), and threat systems
- Assist with integration of RF models into larger simulation frameworks and distributed architectures
- Participate in lab and field testing, including setup of SDRs, spectrum analyzers, and RF test equipment
- Document designs, test procedures, and results in support of internal development and government deliverables
- Collaborate with senior engineers on system design, debugging, and performance optimization
Required Qualifications
- Bachelor’s degree in Electrical Engineering, Computer Engineering, Physics, or related field
- 0–3 years of experience (internships or academic projects acceptable)
- Fundamental understanding of RF principles (modulation, propagation, link budgets, noise, interference)
- Experience with Python and/or C++
- Familiarity with DSP concepts (sampling, filtering, FFTs, modulation schemes)
- Exposure to SDR platforms (e.g., GNU Radio, HackRF, USRP, etc.)
- Ability to work in a hands-on lab environment with RF hardware
- Strong analytical and problem-solving skills
Preferred Qualifications
- Experience with GNU Radio and RFNoC-style architectures
- Familiarity with wireless protocols (WiFi, LTE, GNSS, TETRA, ISM band systems)
- Experience measuring and analyzing RF signals (EVM, constellation plots, spectrum analysis)
- Exposure to EW concepts (jamming, detection, LPI/LPD techniques)
- Experience with modeling & simulation tools (AFSIM, MATLAB, or similar)
- Understanding of Linux environments and scripting
- Experience with version control (Git)
Nice-to-Have (High Impact Areas)
- Experience implementing DSSS/CDMA systems or spread-spectrum techniques
- Familiarity with RF impairments and calibration (phase noise, IQ imbalance, nonlinearity)
- Exposure to GPU or parallel computing concepts
- Interest in integrating AI/ML techniques into RF signal processing workflows
