Senior Mechanical Engineer for Undersea Systems

Full TimeLocalWoburn-MAConfidential Company (Register)

<Confidential (Registered Users Only)ong>About the Team:
Confidential (Registered Users Only)ong>
The Sensors Division within Confidential (Registered Users Only) 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.

<Confidential (Registered Users Only)ong>The Role:Confidential (Registered Users Only)ong>

We are seeking a Senior Mechanical / Ocean Engineer to develop technical solutions for complex, diConfidential (Registered Users Only)ibuted uncrewed undersea systems—including vehicles, buoys, and ocean bottom nodes. In this role, you will work with high‑level 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 C‑ISR missions. You’ll 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.
