Senior Mechanical Engineer for Undersea Systems

About the Team:

The Sensors Division within STR focuses on the development and analysis of advanced sensor systems in the RF acoustic and electro-optical domains. This includes the design and development of novel sensors and advanced information processing techniques from ideation to prototype implementations. The Subsea and Seabed Systems (SSS) Group develops and delivers advanced undersea sensor and signal processing systems including bespoke undersea vehicles to deploy those systems. We apply those products to to intelligence surveillance and reconnaissance (ISR) and counter-ISR applications to deliver missions success to our customers.

The Role:

We are seeking a Senior Mechanical / Ocean Engineer to develop technical solutions for complex distributed uncrewed undersea systemsincluding vehicles buoys and ocean bottom this role you will work with highlevel guidance from a Principal Investigator or Chief Engineer but own the detailed engineering: turning concepts into designs prototypes and fielded systems through analysis fabrication integration and testing.

You will collaborate closely with multidisciplinary teams (mechanical electrical acoustics software systems) to realize novel system concepts for ISR and CISR missions. Youll be expected to build and apply domain expertise proactively suggest next steps perform peer reviews and contribute to reports proposals and presentations that capture your results and ideas.

What You Will Do:

• Develop mechanical and ocean engineering solutions for distributed uncrewed undersea systems from concept through detailed design fabrication integration and test
• Lead technical tasks within small multidisciplinary teams coordinating closely with electrical acoustics embedded systems and power engineers to balance complex systemlevel tradeoffs
• Design and analyze key undersea structures and subsystems including:
• Pressure vessels and housings for deepwater operation
• Hydrodynamic forms and appendages
• Thermal management and power system packaging
• Shock vibration stability and control aspects
• Transducer and actuator mounting and integration
• Model analyze and simulate electromechanical fluid and thermal systems using custom or commercial tools (e.g. FEA CFD thermal analysis) to inform design decisions and predict performance
• Contribute to the design and implementation of undersea acoustic hardware prototypes ensuring mechanical designs support acoustic performance reliability and manufacturability
• Work with teammates to model and simulate advanced undersea acoustic systems across scalesfrom individual sensor physics to systemlevel and theaterlevel behaviorproviding mechanical and ocean engineering insight
• Perform peer reviews and suggest next steps for ongoing research and development activities helping shape followon tasks and programs
• Support the development of best practices and capabilities for designing producing integrating and testing distributed uncrewed undersea systems; identify gaps and propose approaches to address them
• Contribute to technical communications (reports briefings proposals and presentations) that summarize your designs analyses test results and recommendations for customers sponsors and internal stakeholders

Who you are:

• Active security clearance with eligibility to support special access programs for which U.S citizenship is needed by the U.S government
• BSwith at least 5 years of relevant experience MS with at least 3 years of relevant experience or PhD in Mechanical Engineering Ocean Engineering Physics or a related technical discipline.
• Experience developing mechanical/ocean engineering solutions for advanced research and development projects preferably in undersea or harshenvironment systems
• Strong knowledge in several of the following areas:
  • Pressure vessels and deepwater structures
  • Hydrodynamics and stability of undersea vehicles and platforms
  • Thermal management and power system integration
  • Shock and vibration design and mitigation
  • Transducers actuators and their mechanical integration

• Handson experience progressing from concepts to fielded systems supported by:
  • Analytical modeling and simulation (including FEA or similar tools)
  • Prototyping and fabrication
  • Lab pool and/or atsea testing
• Ability to work with highlevel guidance and independently develop detailed technical solutions identify risks and propose mitigation strategies.
• Ability to survey technical literature understand stateoftheart developments and incorporate relevant research into current problem sets.
• Strong communication skills including:
  • Clear documentation of designs analyses and test results
  • Contribution to technical briefings and reports for customers and senior management

Even Better:

• Experience with distributed uncrewed undersea systems (UUVs buoys ocean bottom nodes) and their mechanical/ocean engineering challenges
• Familiarity with acoustic systems and how mechanical design impacts acoustic performance and noise control
• Experience working in multidisciplinary R&D teams collaborating across mechanical electrical acoustics and software disciplines
• Prior interaction with U.S. Government or defense customers and understanding of how mission needs translate into engineering requirements
• Experience supporting proposal development including providing technical input estimates and risk assessments

This Senior role is ideal for an engineer who enjoys owning challenging mechanical and ocean engineering problems collaborating across disciplines and turning advanced concepts into robust undersea systems.
