Senior Mechanical Engineer
Confirmed on the employer's own hiring board on Oct 15, 2026. First seen by Alion on Aug 13, 2026.
About the Role
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 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.
Responsibilities
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 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.
Required Qualifications & Skills
Bachelor's degree in Mechanical Engineering or a related field.
5+ years hands-on experience with CAD 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.
Desired Qualifications & Skills
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
