Vacuum Systems Mechanical Engineer

Responsibilities

Develop and specify pump-down and vent procedures to meet vacuum system flow requirements.
Perform analyses and calculations to predict and optimize flow architecture functionality, including pressure drop, flow budgeting, humidification, and gas purity.
Design equipment using NX CAD
Work with vendors for custom and OTS devices and instruments.
Select instruments for gas analysis such as RGAs and FTIR
Work with the controls team on device integration.
Ensure functional integration of vacuum architectures and subsystems through analysis, documentation, and machine testing.
Manage pressure and vacuum vessel certifications, proof-tests, and compliance with code standards.
Lead design efforts for prototype systems and subsystems, including Preliminary and Final Designs.
Troubleshoot escalations and derive practical recommendations for improvements.
Collaborate with mechanical, laser, pulsed power, and optical engineering teams throughout the design and development process.
Support procurement of vacuum-related hardware for laser amplifiers and optical conditioning equipment.
Oversee and assist with assembly, shakedown, and testing of vacuum systems on laser amplifiers and ancillary equipment.
Provide operational support for vacuum systems and equipment.
Contribute to scaling designs for power-producing IFE reactors and participate in concept studies for IFE applications and beyond.
