Mechanical Engineer

About The Position

We're looking for a Mechanical Engineer to own the structural and mechanical design that makes our underwater robotic systems work. You'll design the hardware that operates above and below the surface—pressure housings, sealing systems, thruster assemblies, linkages, and everything in between—and you'll be responsible for making it robust enough to perform autonomously in one of the most unforgiving environments on the planet. This is a hands-on role at the intersection of design and fabrication. You'll work directly with electrical, software, and acoustics engineers to develop new assemblies, integrate sensors and actuators into watertight enclosures, and build the mechanical infrastructure that our autonomy and navigation systems depend on. You'll see your designs go from CAD and prototyping to ocean deployment, and you'll be the person troubleshooting them at every stage.

Requirements

• Hands-on experience working on ocean hardware—ideally something impressive you can show us.
• Bachelor’s degree (or talented dropout) in Mechanical Engineering or a related field.
• Comfortable collaborating with electronics and firmware teams to ensure that mechanical designs interface smoothly with embedded hardware.
• Proficient in CAD/CAE tools (e.g., Onshape, NX, Solidworks) and version control.
• Solid understanding of sensor integration, actuator selection, and communication protocols.
• Comfortable bridging mechanical and electrical domains at a systems level.
• Strong problem solver who thrives on working independently in dynamic, fast-paced environments.
• Availability to travel outside and inside the USA, including locations such as Australia, the EU and East Coast USA.

Nice To Haves

• Experience scaling production from prototype to mass manufacture
• Exposure to high-power electromechanical setups, power pack design, or BMS integration
• Taken USVs or UUVs from concept to production, overseeing prototyping, testing, and mechanical/electrical integration.
• Knowledge of CAM systems and experience with CNC machines
• Training and experience in welding

Responsibilities

• Conceptualise, develop and integrate mechanical subsystems for autonomous surface & subsurface vehicles. Focus on robust and scalable design, efficient power/thermal management, system reliability, and rapid & reliable actuation in marine environments.
• Expect to take projects from early conceptual design through to fully functional prototypes - owning your own prototypes from start to finish.
• Work closely with the electronics team to ensure seamless integration of custom electronics.
• Validate designs in the lab and in real-world ocean conditions.
• Identify and resolve mechanical or subsystem-level issues to ensure reliability and performance under dynamic marine environments.
• Bodging skills are a necessity, but always hopefully avoided.
