Marine Engineer

ABOUT US

MOBY Robotics is building advanced autonomous robotic systems to unlock the ocean’s potential through scalable, persistent operations at depth. Our platform integrates subsea robotics, onboard sensing, and intelligent control to enable continuous ocean data collection, infrastructure inspection, and interaction with the seafloor.

A key component of this system is MOBY’s smart buoy platform, a dynamically positioned surface node enabling subsea docking, wireless data offload, and in-situ charging of autonomous vehicles. This system acts as the bridge between subsea operations and persistent ocean infrastructure. Join us to help design and deploy next-generation ocean systems.

THE ROLE

We are seeking a Marine Engineer or Naval Architect to own the design, analysis, and deployment of our smart buoy platform. This is a highly interdisciplinary role focused on hydrodynamics, station-keeping, structural design, and real-world ocean performance.

You will lead the development of a dynamically positioning system that supports AUV docking, offshore charging, and data transfer, operating reliably in challenging sea states. This role is ideal for a strong graduate, Master’s student, or PhD candidate looking for hands-on ownership of a full ocean system, from concept through field deployment.

KEY RESPONSIBILITIES

Buoy & System Design

• Design and develop MOBY’s smart buoy platform for offshore deployment
• Own hull form, structural layout, and subsystem integration (power, comms, docking interface)

Hydrodynamics & Seakeeping

• Perform seakeeping analysis to evaluate buoy motion response across sea states
• Model and optimize system behavior for docking stability and operational uptime
• Analyze wave-body interactions and minimize relative motion for subsea operations

Mooring

• Design and analyze mooring systems for various deployment environments
• Perform load analysis for mooring lines, anchors, and structural components

Powering & Dynamic Positioning

• Estimate power requirements for station-keeping, onboard systems, and charging
• Support development of station-keeping strategies
• Work closely with controls/software teams on DP integration

Modeling & Simulation

• Build and maintain CAD models (Rhino or similar)
• Perform simulations for hydrodynamics, loads, and system behavior
• Support rapid iteration between design and field validation

Field Testing & Operations

• Support offshore deployments and system validation
• Analyze field data to refine models and improve performance
• Contribute to operational planning and logistics

REQUIRED QUALIFICATIONS

• Degree (or pursuing) in Naval Architecture, Marine Engineering, Ocean Engineering, or related field
• Strong fundamentals in hydrodynamics, stability, and marine systems design
• Experience with seakeeping and/or mooring analysis
• Proficiency in CAD tools (e.g., Rhino or similar)
• Understanding of ocean environments and offshore operations
• Hands-on engineering mindset with ability to build, test, and debug systems

PREFERRED QUALIFICATIONS

• Graduate-level research (MS or PhD) in a relevant field
• Experience with:
• Mooring design tools (OrcaFlex, ProteusDS, etc.)
• Seakeeping analysis (WAMIT, AQWA, or similar)
• Small vessel or offshore system design
• Marine robotics
• Ocean deployments or field experience
• Dynamic positioning systems
• Marine power systems (batteries, solar, hybrid systems)
• Subsea systems and sensors (acoustic modems, CTD, imaging sonar)

WHAT WE OFFER

• Ownership of a critical ocean system from concept to deployment
• Competitive pay
• Hands-on work in real marine environments
• Rapid iteration between design, simulation, and field testing
• Small, highly technical team with broad system exposure
• Opportunity to shape next-generation ocean infrastructure
