Principal RF​/DSP Engineer

A client in the Leesburg, VA area is seeking a Principal RF/DSP Engineer in support of a counter-UAS product. This will be a contributor role and requires a high level of independence and autonomy.

The Principal RF/DSP Engineer will own our most difficult and least-documented RF targets end-to-end — signals where the first several hypotheses will be wrong, where documentation does not exist, and where the path from "we recorded something" to "we can reliably detect and identify it" must be invented, not followed. Given only a newly encountered drone/controller pair and complex-IQ recordings, this engineer will independently frame the problem, generate and rank hypotheses, design the experiment campaign, characterize the waveform, develop the algorithms, implement them in production C++, and validate performance against real-world RF data — without needing the approach handed to them

• BS in EE, Computer Engineering, Applied Physics or related
• MA/MS or PHD is preferred
• 10+ years of experience in a Sr/Principal RF/DSP Engineer or related
• can be flexible upon experience but needs to be relevant DSP Engineer
• Strong DSP and digital-communications fundamentals, including several of the following:
  Sampling and aliasing;
  Digital down conversion; FIR/IIR and multirate filtering; FFT and time-frequency analysis;
  Matched filtering;
  Detection and estimation;
  Carrier, phase, symbol-timing, and frame synchronization;
  Modulation and demodulation;
  Channel coding and error detection
• Hands-on experience implementing, testing, and debugging DSP algorithms
• Proficiency writing production-quality C++ in a Linux environment
• MATLAB
• previous EW or Defense Tech Production environment
• must be building or in a production environment-working in immediate team of 4-tar getting different signals in dense RF environments
• will be in an office setting
• detecting signals rather than building products-existing products and new product development
