Mechanical Engineer — Component Design, Test & Integration

• Help plan and perform experimental testing of components and sub-systems
• Use analysis from the thermal-hydraulics team to size components, engage vendors, and explore the design space.
• Build and maintain NX CAD models and generate the required drawings for components and sub-systems.
• Design with the marine environment in mind — vibration, shock, thermal cycling, corrosion, and tight volumetric constraints aboard a vessel.
• Collaborate across nuclear, thermal, and software teams; give and receive feedback openly.

• Bachelor's degree in Mechanical Engineering or a related field.
• Hands-on experience with CAD (NX preferred; SolidWorks/Creo acceptable) and drawing generation, including GD&T.
• Exposure to hardware testing, component sizing, or vendor interaction (internships/projects count).
• A pragmatic, curious, low-ego approach to problem-solving.

• Experience with FEA or first-principles hand calcs to inform design.
• Familiarity with marine, nuclear, aerospace, or other regulated hardware environments.
• Experience shepherding a part from design → fab → test → iteration

You'll turn analysis into hardware.

You'll help run experimental testing and use the thermal-hydraulic team's analysis to size components, talk to vendors, and explore the design space.

You’ll design test campaigns, create test plans and procedures, run and acquire data from experiments, and turn this knowledge into system-level designs for our production units.

You'll build models in NX CAD and generate the drawings needed for components and sub-systems.

This is a hands-on, collaborative role with room to grow — a great fit for someone eager to learn, comfortable asking questions, and happy to get their hands dirty in the lab and on the deck plate.

On-Site Requirement: Our team works together at our Long Beach facility, right next to our barge.

Highly Cross-Functional: Startups move fast!

You must possess the ability to seamlessly collaborate across multiple teams to rapidly solve problems and keep production moving.

Physical & Machinery Requirements: Because we are a hands-on startup, this role may require the ability to perform physical labor, navigate active construction/manufacturing zones, and/or operate heavy machinery and specialized manufacturing equipment as needed.
