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.

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 :
