Job Summary

Applied Physical Sciences (APS) is seeking a Senior Scientist – Sonar Signal Processing to join their team. The role involves designing, implementing, and optimizing signal processing algorithms for active/passive sonar systems, collaborating with multidisciplinary teams, and guiding junior engineers.

Job Functions and Responsibilities

  • Design, implement, and optimize signal processing algorithms for active/passive sonar (beamforming, matched filtering, CFAR, DOA/TMA, adaptive noise cancellation, multi-target tracking, clutter suppression, reverberation mitigation)
  • Develop array processing architectures (planar, conformal, towed arrays) including beamspace, subspace, and adaptive techniques (MVDR, LCMV, etc.)
  • Construct and validate end-to-end sonar performance models (SNR budgets, reverberation-limited regimes, ROC analysis)
  • Decompose system requirements, create processing architectures and interfaces, and support design reviews (SRR/PDR/CDR)
  • Provide technical guidance, peer reviews, and design leadership; set best practices in signal processing and embedded optimization
  • Collaborate with cross-functional engineering teams to integrate signal processing components into embedded, real time, or distributed sonar systems
  • Plan and execute lake and sea trials, conduct acceptance testing, analyze test logs, and iterate designs based on findings
  • Validate algorithms through simulation, lab testing, and data analysis, ensuring alignment with system requirements and operational use cases
  • Define processing requirements & interfaces for real-time and embedded pipelines; collaborate with firmware/software for implementation
  • Support sensor/array selection, transducer parameters, and front-end analog/digital chain trades (sampling, dynamic range, quantization)
  • Document and present results to various peer-review and working groups

Required Skills and Attributes

  • B.S., M.S., or PhD in Electrical Engineering, Computer Engineering, Data Science, Applied Mathematics, or Signal Processing
  • Five or more years of relevant experience
  • An understanding of and demonstrated proficiency in the areas of sonar signal processing, such as detection and estimation theory, digital signal processing, probability and statistics, spectral analysis, communications, and underwater acoustics
  • Demonstrated experience presenting program updates, analyses, or technical material to sponsors, customers, and technical working groups
  • Occasional travel required, typically less than 10%
  • Active security clearance or the ability to obtain one (Secret or higher)

Preferred Skills and Attributes

  • Prior experience with algorithm development, implementation, and analysis for complex signal processing applications
  • Proficiency in MATLAB, C/C++, Python
  • Experience with Target Tracking & Detection Theory
  • Gitlab or similar experience
  • Experience in machine learning techniques applied to signal processing
  • Familiarity with embedded system constraints (latency, power, quantization) at a requirements and design-analysis level
  • Experience supporting the development of technical proposals and related documentation
  • Demonstrated experience analyzing real-world acoustic or sonar data
  • Ability and willingness to participate in occasional at-sea test events

Location

On site in Groton, CT or Concord, MA
