Undersea Acoustics Engineer

Xtreme Sonar is seeking an undersea acoustics engineer to join our advanced underwater systems team. This role is focused on designing, implementing, and deploying cutting-edge sonar and underwater communication solutions in real-world environments. The ideal candidate combines deep domain expertise in acoustics with hands-on hardware and software development experience, and a track record of delivering production-ready systems. Preference is given to candidates with an electrical engineering background and related skill sets. What you’ll do Lead design and development of underwater acoustic systems, including sonar, hydrophones, transducers, and acoustic communication components. Apply and extend sonar theory (propagation, array processing, the sonar equation) to real-world deployments and field trials. Build and optimize end-to-end hardware/software stacksConduct system integration, testing, and field deployments in real conditions; demonstrate a track record of turning models into working, reliable systems. Drive scale-to-production activities: cost-down iterations, design for manufacturability (DFM/DFT), supplier selection, manufacturing documentation, calibration procedures, and automated test fixtures. Improve yield, reliability, and maintainability through robust engineering practices and documentation. Collaborate with cross-functional teams including electrical, mechanical, software, and operations to deliver integrated solutions. What you bring 4+ years of hands-on experience in acoustics with underwater systems, sonar, hydrophones, or related technologies. Strong background in underwater acoustics concepts: propagation, array theory, sonar equation, and acoustic communication systems. Demonstrated track record of building and deploying working systems in real conditions, not just theoretical models. Proficiency with MATLAB for analysis, modeling, and data-driven decision making. Experience building the hardware/software stack for acoustic systems, including:Analog front-end design and signal conditioningTiming, synchronization, and embedded compute constraintsInterfaces such as Ethernet, serial, CAN, PPSTransducer selection and design tradeoffsFirmware, drivers, and logging/observabilityExperience scaling products to production: cost-down iterations, DFM/DFT, supplier engagement, manufacturing documentation, calibration procedures, automated test fixtures, and yield improvements. Strong problem-solving, communication, and collaboration skills. Eligibility to qualify for US security clearanceElectrical engineering background preferred, with emphasis on electrical design, signal processing, and systems integration; familiarity with electrical CAD tools, power management, and RF/analog design is a plus. Nice to Have Strong fundamentals in design for manufacturing (DFM)Proficiency creating BOMsFamiliarity with impedance matching and waterproofing methods Location and travel On-site role in Stuart, Florida. Occasional travel may be required for field testing, supplier visits, and program milestones. What we offer Opportunity to shape advanced underwater acoustics technologies used in challenging environments. Collaborative, multidisciplinary team with a hands-on engineering culture.
