Senior Mechanisms Engineer

About the Role

Radiant is seeking a highly motivated Senior Mechanisms Engineer to design and develop critical mechanisms within Kaleidos. You will solve unique challenges creating efficient and reliable mechanisms that control reactivity or actuate critical safety features. You will be responsible for the following: trade studies, material selection, detailed structural analysis, assembly, integration, and testing. You will have an instrumental impact of fueling the first new commercial reactor design in over 50 years by 2026.   

Responsibilities & Duties:  

• Ownership of critical mechanisms such as the control blade actuator or air jacket valves.

• Conduct trade studies and develop designs to meet program requirements. 

• Perform detailed thermomechanical analysis (static strength, durability/fatigue) and kinematic analysis to determine structural integrity and performance margins using both hand calculations and finite element tools.

• Develop and execute manufacturing/assembly instructions and test plans.

• Create and manage a Bill-Of-Materials (BOM).

• Find and develop suppliers for components.

• Own subassembly design, manufacturing, and test schedules.

• Own risk analysis (FMEA) for subsystems.

• Collect requirements, provide expertise and feedback to engineers in other functional areas via clear, constructive communication. 

Required Qualifications & Skills: 

• Bachelor’s degree from an accredited institution in Mechanical or Aeronautical Engineering.

• 4+ years of experience designing mechanisms.

• 4+ years of experience performing stress analysis using both hand calculations and finite element tools (Abaqus, Ansys, FEMAP, or similar). 

Desired Qualifications & Skills: 

• Experience with design of multi-component assemblies in CAD (NX or similar).

• Experience designing hardware that was manufactured, deployed, and iteratively improved.

• Experience designing pneumatic systems.

• Experience integrating electromechanical components such as motors or encoders.

• Experience working with interdisciplinary teams.

• Solid understanding and application of GD&T.

• Proficiency with both “hand calc” analytical methods and higher fidelity finite element-based analysis methods.

• Ability to derive free-body diagrams for systems with which one was not previously familiar.

• Self-motivated with strong organizational, written, and oral communication skills.

• Experience with using text-based software development tools. 

Additional Requirements:

• Must be willing to work extended hours and weekends as necessary to accomplish our mission.

Benefits and Perks

• Stock: Substantial incentive stock plan for all full-time employees.

• Daily catered lunch. Free snacks and drinks.

• Flexible PTO policy. Remote workday allocation.
