About the Job

Requirements

  • At least 2 years of experience with underwater acoustic propagation modeling using physics-based solvers such as BELLHOP/BELLHOP3D, RAM/PE, CASS, SST, Acoustics Toolbox, KRAKEN, SCOOTER/SPARC, OASES, or equivalent tools. Experience should include fluency in ocean acoustics fundamentals, including sound speed structure, volume and boundary interactions, signal propagation and coherence, ambient noise characterization, and use of analytical models and databases.
  • At least 4 years of experience developing end-to-end acoustic analysis workflows integrating propagation models, MATLAB processing, environmental databases, and scripting or programming wrappers such as Bash and C.
  • At least 3 years of experience evaluating acoustic system design and performance, including ocean propagation and noise properties, sensor transduction, front-end signal conditioning, phased array design, underwater telemetry, sonar and communications signal processing, and operator interface and data display considerations.
  • At least 2 years applying acoustic modeling to operational underwater systems, such as seabed sensor networks, mobile platform sonar suites, or underwater acoustic communication channels.
  • At least 2 years of experience converting model outputs into engineering artifacts, including performance budgets, detection range estimates, coverage assessments, and operational scenario analyses.
  • At least 2 years of experience with experimental methods for ocean acoustics and sonar or communications system characterization, including planning and executing sea tests, defining objectives and metrics, specifying acoustic sources and receivers, coordinating at-sea recording and quality assurance, assigning participant responsibilities, and managing collected data through analysis and reporting.
  • At least 1 year of leadership experience guiding modeling standards, improving internal toolchains, mentoring junior engineers, and shaping long-term modeling and simulation strategy for undersea systems.
  • At least 5 years of experience in systems engineering and the government program acquisition lifecycle.
  • At least 2 years working within standard systems engineering processes, such as MIL-STD-499, EIA-632, IEEE 1220, or IEEE/ISO/IEC 15288.
  • At least 3 years of experience with DOORS and Model-Based Systems Engineering (MBSE).
  • Ability to obtain and maintain a U.S. Department of Defense security clearance, which requires U.S. citizenship.

Responsibilities

  • Review, analyze, and understand program-level objectives, system concepts of operation, system and subsystem equipment, functions, interfaces, and operations.
  • Define, flow down, and trace requirements for complex electronic systems using model-based systems engineering processes to enhance development speed and quality.
  • Develop and maintain computer models of sonar system performance based on ocean sound propagation principles, source and receiver characteristics, and signal detection algorithms.
  • Collaborate with other Systems Engineers to develop system specifications, logically derived and linked requirements, interface definitions, system diagrams, systems analyses, trade studies, and detailed designs.
  • Develop and coordinate engineering artifacts for program design reviews, and participate in technical exchanges with customers and subcontractors.
  • Support Systems Engineering execution within the business area across cost, schedule, and technical areas.
  • Validate modeling outputs by cross-checking against established legacy tools and physics-based benchmarks to ensure model fidelity and traceability.
  • Architect, analyze, develop, and integrate end-to-end systems.
  • Evaluate overall systems project risks and support risk mitigation planning and execution with program and functional leadership.
  • Analyze customer requirements and allocate performance specifications among end-to-end system elements.
  • Conduct analysis and design tests to validate system designs. Support testing activities by developing plans, providing data recording and analysis requirements, and producing analysis reports.
  • Analyze data from design verification test efforts and maintain test results.
  • Brief status and results to program and customer stakeholders.
  • Participate in sea trials and system installations.

Desired Qualifications

  • Active DoD Secret clearance with a current 6-year update.
  • Experience with DOORS, Cameo suite of MBSE tools or similar, and MS Visio.
  • Experience with Earned Value Management.
  • Familiarity with underwater products and acoustics.
  • Working knowledge of Cisco routers and switches.
  • Experience with RF communication theory.
