Senior Sonar Signal Processing Architect

Applied Physical Sciences Corp (APS); Concord (MA); On-site; USD 120,000 - 170,000; Full time

Job summary

Applied Physical Sciences (APS) seeks a Sonar Signal Processing Engineer to join our growing team, with on-site work in Groton, CT or Concord, MA. You will design, implement, and evaluate advanced sonar algorithms for active and passive systems that support critical U.S.

Navy programs. You will also mentor junior engineers, collaborate across disciplines, and drive real-world capabilities from concept to field tests, focusing on robust real-time processing, embedded optimization, and rigorous

Qualifications

• 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
• Understanding and proficiency in sonar signal processing areas (detection, estimation, DSP, statistics, spectroscopy, underwater acoustics)
• Experience presenting program updates and analyses to sponsors, customers, and technical working groups
• Occasional travel typically less than 10%
• Active security clearance or ability to obtain one (Secret or higher)

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)
• 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
