Full Job Description

Description

Leidos’ High Fidelity Simulation Business Area designs and delivers cutting-edge system-of-systems solutions that power world-class simulation, training, and analysis products for the U.S. Navy. In this role, you will leverage your Naval operational and acoustic expertise to support the design, development, and delivery of advanced sonar tactical decision aids (TDAs) and related tools. You will collaborate with software developers, analysts, and fleet users to ensure tactical realism, operational relevance, and technical excellence in Leidos’ undersea warfare products.

This position offers a unique opportunity to directly impact Fleet readiness and undersea dominance by applying your anti-submarine warfare (ASW) knowledge to real-world mission systems.

What You’ll Work On

Serve as the primary subject matter expert (SME) for Integrated Undersea Surveillance System and secondary SME for other TDA systems such as STK and STK-N.
Participate in development planning, functional system testing, and program verification tests (PVTs) at development or fleet facilities.
Collaborate with cross-functional development teams to ensure operational accuracy in acoustic models, sensors, and system interfaces.
Prepare and deliver detailed briefings and analyses to fleet stakeholders and external organizations.
Provide operational insight into ASW system performance, sonar data interpretation, and tactical employment strategies.
Apply project and team management skills to coordinate tasking, track progress, and ensure on-time delivery of system upgrades, documentation, and training.

Primary Responsibilities

Apply in-depth ASW, acoustic, and oceanographic knowledge to system design, testing, and evaluation.
Perform functional and verification testing of sonar tactical decision aid software across multiple system configurations.
Collaborate with developers to troubleshoot, verify, and validate system functionality and user interface improvements.
Develop and maintain training materials, user guides, and operational procedures.
Interface with government customers, fleet representatives, and partner organizations to gather feedback and align capabilities with user needs.
Travel (up to 25%) to fleet sites or test facilities for demonstrations, training, and system testing.

Basic Qualifications

12+ years of fleet operational experience directly related to ASW operations, systems, and theory in lieu of degree; OR bachelor’s degree in mathematics, physics, acoustics, oceanography, or engineering and 10+ years of directly related ASW operational experience.
Experience working at an IUSS site supporting mission operations.
Familiarity with recent undersea warfare tactics, acoustic sensors, and beamforming principles.
Background in acoustic theory or oceanography.
Proven ability to build strong working relationships across multi-disciplinary teams.
Ability to obtain an interim security clearance.

Desired Qualifications

Excellent oral and written communication skills, including technical documentation and stakeholder briefings.
Knowledge of Fleet acoustic analysis tools.
