This role focuses on the research, evaluation, and development of underwater acoustic sensing technologies - including sonar transducers, hydrophones, acoustic modems, and signal processing subsystems - supporting navigation, detection, and situational awareness capabilities for autonomous surface vessels. The ideal candidate has extensive experience in acoustic system design, integration, and testing within marine or defense environments, and a strong background in hardware evaluation, data analysis, and system trade studies. Key Responsibilities: * Lead R&D initiatives in maritime acoustic sensing and underwater signal systems for autonomous vessel applications. * Evaluate and benchmark acoustic sensors and subsystems (e.g., sonar arrays, hydrophones, acoustic modems, Doppler sensors) across commercial and defense-grade offerings. * Design and execute experiments for acoustic performance testing, calibration, and environmental validation in laboratory and sea-trial conditions. * Develop and analyze trade studies comparing acoustic hardware and architectures to inform system selection, performance optimization, and integration paths. * Design and document system architectures for acoustic data acquisition, amplification, filtering, and digital conversion. * Collaborate with autonomy, software, and mechanical teams to integrate acoustic systems into vessel control and perception frameworks. * Develop and validate signal conditioning and analog front-end circuitry for low-noise, high-fidelity acoustic measurements. * Author detailed R&D documentation, including test reports, design specifications, and performance assessments. * Contribute to system safety, reliability, and environmental qualification efforts, including compliance with applicable maritime and defense standards. * Mentor junior engineers and contribute to Saronic’s acoustic sensing roadmap and experimental methodologies. Required Qualifications: * B.S. or M.S. in Electrical Engineering, Acoustics, or related discipline. * 7+ years of experience in acoustic system design, integration, or testing - preferably in commercial marine, defense, or undersea applications. * Expertise with underwater acoustics, including sonar, hydrophones, and acoustic communication systems. * Experience in hardware benchmarking, R&D testing, and performance analysis of acoustic sensors and electronics. * Strong understanding of signal processing concepts, analog front-end design, and data acquisition systems. * Familiarity with marine environmental factors affecting acoustic propagation (temperature, salinity, depth, and noise). * Proficiency in schematic design and documentation tools (e.g., Altium, AutoCAD Electrical, or SolidWorks Electrical). * Hands-on experience with lab instrumentation (oscilloscopes, spectrum analyzers, data loggers, acoustic test equipment). * Strong technical writing and presentation skills, with ability to produce rigorous R&D and evaluation documentation. * Comfortable working in laboratory, dockside, and sea-trial environments. Preferred Qualifications: * Experience developing or integrating active and passive sonar systems for maritime platforms. * Familiarity with acoustic transducer design, impedance matching, and waterproofing methods. * Knowledge of marine and defense standards (MIL-STD-167, MIL-STD-461, IEC 60529, etc.). * Experience with acoustic modeling software (e.g., COMSOL, MATLAB, BELLHOP, or equivalent). * Background in sensor fusion and data analysis pipelines for multi-sensor acoustic systems. * Experience supporting hardware-in-the-loop (HITL) or real-time signal processing systems. Benefits: * Medical Insurance: Comprehensive health insurance plans covering a range of services * Dental and Vision Insurance: Coverage for routine dental check-ups, orthodontics, and vision care * Saronic pays 100% of the premium for employees and 80% for dependents * Time Off: Generous PTO and Holidays * Parental Leave: Paid maternity and paternity leave to support new parents * Competitive Salary: Industry-standard salaries with opportunities for performance-based bonuses * Retirement Plan: 401(k) plan * Stock Options: Equity options to give employees a stake in the company’s success * Life and Disability Insurance: Basic life insurance and short- and long-term disability coverage * Additional Perks: Free lunch benefit and unlimited free drinks and snacks in the office Physical Requirements: * Prolonged periods of sitting at a desk and working on a computer. * Occasional standing and walking within the office. * Manual dexterity to operate a computer keyboard, mouse, and other office equipment. * Visual acuity to read screens, documents, and reports. * Occasional reaching, bending, or stooping to access file drawers, cabinets, or office supplies. * Lifting and carrying items up to 20 pounds occasionally (e.g., office supplies, packages). Additional Information: * This role requires access to export-controlled information or items that require “U.S. Person” status. As defined by U.S. law, individuals who are any one of the following are considered to be a “U.S. Person”: (1) U.S. citizens, (2) legal permanent residents (a.k.a. green card holders), and (3) certain protected classes of asylees and refugees, as defined in 8 U.S.C. 1324b(a)(3). ## Skills ### Required - Electrical Engineering - Acoustic System Design - Integration and Testing - Hardware Evaluation - Data Analysis - Signal Processing - Analog Front-end Design - Data Acquisition Systems - Marine Environmental Factors - Schematic Design and Documentation Tools - Lab Instrumentation - Technical Writing and Presentation ### Nice to have - Active and Passive Sonar Systems - Acoustic Transducer Design - Impedance Matching and Waterproofing Methods - Marine and Defense Standards - Acoustic Modeling Software - Sensor Fusion and Data Analysis Pipelines - Hardware-in-the-Loop (HITL) or Real-time Signal Processing Systems
