Senior Mechanical Engineer

Overview

The Sensors Division at STR excels at applied research and advanced technology development of impactful sensor system technology to address warfighter and intelligence needs. Our contributions are the culmination of modeling, development, integration, and test and evaluation of new capabilities, with validation testing at each step of development.

The Ocean Technology and Acoustic Systems (OTAS) Group within the Sensors Division executes a broad portfolio of undersea technologies to impact sensing capabilities in contested areas. The Group develops signature exploitations, implements advanced algorithms and processing, and creates new sensing and payload technologies for critical undersea missions. The technologies can be stand‑alone or for platforms such as AUVs.

STR is seeking a Senior Mechanical Engineer with experience in the design, fabrication, integration, and testing of subsystems or payloads for unmanned platforms with emphasis on undersea sensors, payloads and vehicles. You will work with teams to realize challenging undersea applications requiring novel and complex engineering solutions. These solutions can only be accomplished by working across multidisciplinary teams to implement and demonstrate them in specific warfighter and intelligence applications.

• Develop technical solutions for mechanical deployables and vehicles, taking into account their complex interactions with harsh maritime environments. This work requires teamwork in key areas of design and simulation, fabrication, and validation testing of mechanical payloads and systems in underwater environments.
• Collaborate in all stages of undersea systems testing, including developing comprehensive test plans, building test infrastructure, and supporting teams both in the laboratory and at-sea to mature key technology and prototypes.
• Provide regular communication with internal leadership and teammates while providing key input to reports and presentations for customer reviews and engagement.

• Must be able to obtain and maintain a Top Secret security clearance; U.S. citizenship required.
• BS with 5+ years relevant experience, MS with 3+ years, or PhD in Mechanical Engineering, Ocean Engineering, Physics, or related fields.
• Demonstrated background in the design, modeling, fabrication, integration, and validation of mechanical systems in support of first‑concept undersea sensor payloads and vehicles.
• Proficiency with CAD/CAM design tools such as COMSOL, ANSYS, Solid Works and related tools.
• Proficiency in thermal modeling, finite element analysis, computational fluid dynamics, or other multi‑physics modeling and simulation required to quantify system performance in its operational environment.
• Experience with combining multiple external vendors and fabricators with in‑house fabrication and integration resources to arrive at complete systems that meet functional objectives.
• Experience with materials and designs to survive harsh conditions including temperature and over pressure.
• Ability to design and implement testing methods and apparatus to quantify mechanical functionality, performance, and readiness against metrics.
• Adherence to best practices for development and testing using system engineering processes that allow for continuous risk‑reduction and evolution of functionality.
• Ability to prepare and deliver briefings to customers, program managers, and senior management with tailored messages.

• Strong background in working with teams to field ocean‑going unmanned systems in payloads.
