Core Responsibilities

• Design mechanical systems and components for deep-submergence applications to depths of 5000 ft
• Perform mechanical design and analysis of pressure housings, connectors, enclosures, structural components, mechanisms, and subsea assemblies
• Calculate and evaluate hydrostatic pressure, external-pressure loading, buckling, stress, fatigue, and structural margins
• Select materials, seals, fasteners, coatings, and components suitable for high-pressure seawater environments
• Develop designs that address water intrusion, corrosion, galvanic corrosion, sealing, and pressure cycling
• Perform engineering calculations and use FEA/finite-element analysis to validate designs
• Design for manufacturability, assembly, inspection, testing, and field serviceability
• Work closely with manufacturing, electrical engineering, technicians, suppliers, and test personnel to develop and qualify hardware
• Support prototype fabrication, pressure testing, environmental testing, and design modifications
• Analyze test results and failure data and implement design improvements
• Ability to work in a rapid-prototyping environment with agility and openness to change
• Must be able to fabricate and concept prototypes quickly using 3D printing, models and other mockup techniques
• Prepare 3D models and GD&T input for detailed manufacturing drawings considering design intent and customer feedback
• Independently handle moderate to advanced-complexity mechanical design projects
• Interact with all levels of engineering staff and outside vendors
• In-depth understanding of manufacturing processes, to include milling, lathe, waterjet, laser, and typical heavy shop equipment
• Researching and analyzing data such as customer design proposals, specifications, and manuals to evaluate the feasibility, cost, and/or maintenance requirements of the product line
• Work as part of a cross-functional team to resolve system issues and provide technical recommendations for design modifications to eliminate system malfunctions
• Prepare, conduct, and document simulation and mechanical testing to analyze the design, operation, and performance of equipment
• Provide advanced technical writing to capture detailed documentation used for presentations

Requirements

• Experience designing mechanical systems for underwater, subsea, marine, or other high-pressure environments
• Strong understanding of pressure-vessel and external-pressure design principles
• Experience with FEA, structural analysis, fatigue, and buckling analysis
• Knowledge of sealing technologies, O-rings, mechanical seals, pressure barriers, and subsea connectors
• Experience selecting materials for high-pressure seawater and corrosive environments
• Experience taking designs from concept through prototype, testing, qualification, and production
• Strong hands-on problem-solving skills and the ability to work directly with prototype and test hardware
• Ability to independently take ownership of a design task from initial requirements through final implementation
• Willingness to work as part of a team and initiate communication
• Extremely reliable and dependable
• Ability and willingness to travel to support field testing activities in-state and out-of-state (< 15% time)
