Job description:

We are seeking an experienced Mechanical, Electromechanical, Ocean, or Advanced Manufacturing Engineer to support the development of advanced subsea research and development (R&D) systems for DARPA, the Office of Naval Research (ONR), and the broader U.S. Navy.

This position will focus on the design, development, and integration of complex mechanical systems, components, and structures, taking concepts from initial design through detailed engineering, fabrication, and testing.
The successful candidate will balance multidisciplinary system requirements, functional performance, manufacturability, reliability, and lifecycle considerations to deliver innovative engineering solutions for challenging maritime applications.

This role offers an opportunity to contribute to next-generation unmanned undersea technologies, including advanced propulsion systems, innovative manufacturing approaches, and payload integration solutions.

The ideal candidate will have demonstrated experience developing, maturing, and fabricating complex maritime or defense systems while collaborating with engineers, scientists, and mathematicians across multiple technical disciplines.
Success in this position requires strong systems engineering judgment, technical independence, and the ability to evaluate competing design considerations to develop effective, integrated system architectures.

Candidates should be comfortable working in a dynamic, fast-paced R&D environment that emphasizes innovation, technical excellence, and creative problem-solving.
Experience with advanced manufacturing methods, including laser welding, metal additive manufacturing, and the use of specialty materials such as highly alloyed stainless steels, copper-nickel alloys, and titanium, is particularly relevant.

This position offers the opportunity to work in a collaborative, entrepreneurial environment where technical excellence, initiative, and innovation are valued.
The successful candidate will have the opportunity to take ownership of challenging engineering problems and make meaningful contributions to the development of advanced maritime technologies supporting critical national security missions.

Job Functions and Responsibilities
  • Develop and mature innovative mechanical designs, system architectures, and configurations for advanced maritime and subsea systems.
  • Perform engineering calculations and numerical analyses, including thermal, structural stress, buckling, electromagnetic, and other relevant assessments, to evaluate and validate design performance.
  • Conduct system-level trade studies and evaluate design alternatives to balance performance, functionality, cost, weight, size, power, and manufacturability as systems and components mature.
  • Maintain awareness of system-level requirements and ensure design solutions satisfy applicable performance and interface requirements through technical analyses, reports, presentations, and supporting documentation.
  • Identify, assess, and mitigate technical risks associated with novel system architectures, subsystems, operational concepts, and manufacturing approaches.
  • Generate detailed engineering and fabrication drawings and support manufacturing activities through direct coordination with vendors and fabrication partners.
  • Perform dimensional and tolerance analyses and establish appropriate Geometric Dimensioning and Tolerancing (GD&T) requirements.
  • Define, document, and maintain critical mechanical and system interfaces through Interface Control Documents (ICDs) and associated engineering drawings.
  • Design and develop specialized fixtures, tooling, and handling equipment to support assembly, rigging, integration, testing, and demonstrations.
  • Prepare and support technical design reviews through the development and maintenance of comprehensive Technical Data Packages (TDPs).
  • Develop assembly, fabrication, and test instructions to support technician-led manufacturing, integration, and testing activities.
  • Provide technical guidance, leadership, and mentorship to engineers and technicians, supporting technical development and effective execution of engineering tasks.
  • Participate in occasional travel to support government program reviews, vendor engagements, manufacturing activities, and system testing events.
  • Contribute to technical proposals, capture activities, and business development efforts to support new program opportunities.
Required Skills and Qualifications
  • Bachelor's degree in Mechanical, Electromechanical, Ocean, Manufacturing Engineering, or a related technical discipline, with 5+ years of relevant professional experience.
  • Demonstrated experience supporting the design, development, and fabrication of complex, multidisciplinary systems.
  • Ability to work effectively in small, collaborative engineering teams and coordinate technical activities with subcontractors, vendors, and government stakeholders.
  • Strong engineering judgment and the ability to evaluate design decisions, communicate technical impacts, and identify appropriate system-level tradeoffs.
  • Broad understanding of manufacturing processes and the ability to evaluate the advantages, limitations, and applicability of different manufacturing approaches for maritime systems.
  • Demonstrated experience with 3D CAD modeling, engineering design, and technical drawing generation.
  • Strong analytical, organizational, and problem-solving skills.
  • Excellent written and verbal communication skills, including the ability to present technical concepts and engineering recommendations to multidisciplinary stakeholders.
  • Self-motivated and comfortable working independently in early-stage development environments, including projects requiring rapid design iterations and size, weight, and power (SWaP)-constrained redesigns.
Preferred Skills and Qualifications
  • Advanced degree (M.S., M.Eng., or Ph.D.) in Mechanical, Electromechanical, Ocean, Manufacturing Engineering, or a related technical discipline, with 10+ years of relevant professional experience.
  • Experience designing and developing underwater, maritime, autonomous, or subsea systems.
  • Experience supporting defense-related research, development, test, and evaluation (RDT&E) programs.
  • Experience working in multidisciplinary engineering teams involving mechanical, electrical, ocean, software, and systems engineers, as well as applied mathematicians.
  • General familiarity with subsea system components and technologies, including sensors, communications systems, actuators, and propulsion systems.
  • Proficiency with engineering design and analysis tools, including SolidWorks, Product Data Management (PDM) systems, MATLAB, and/or Python.
  • Experience performing dimensional and tolerance analyses, including SolidWorks TolAnalyst or comparable tools such as CETOL 6, EZtol, or 3DCS.
  • Experience with advanced manufacturing processes, including CNC machining, laser welding, and metal additive manufacturing.
  • Functional understanding of electromagnetic and electromechanical components, including motors, transducers, linear actuators, and related technologies.
  • Strong analytical capabilities and the ability to develop practical engineering solutions to complex technical challenges.
