Job Summary

The Caltech/MIT Laser Interferometer Gravitational-Wave Observatory (LIGO) seeks a highly motivated, skilled, and experienced vacuum engineer with a strong background in both chemistry and solid state physics as they apply to UHV systems.

This is a LIGO staff position that will be assigned to the Cosmic Explorer Beamtube Experiment (CEBEX) for an initial three-year term. Current gravitational wave observatories encompass ultrahigh vacuum (UHV) 4km long beamtubes. Next generation detectors like Cosmic Explorer (CE) will be ten times bigger. CEBEX will result in the design, construction, and evaluation of a 120m demonstration tube at the LIGO Hanford Observatory (LHO) site to address the associated engineering challenges of building the next generation systems.

This position is based at the LIGO Hanford Observatory (LHO) in Washington State.

Essential Job Duties

• Designing & Modelling the planned 120m demonstration tube
  • Design in CAD key aspects of the design and integrate them into the overall assembly using Solid Works and the associated PDM Vault.
  • Be responsible for modelling aspects of the design using both finite element packages and mathematical tools.
• Oversee modelling work of others on the team in particular mentoring junior members of the team.
• The design and modelling work will include material, structural, safety, installation, commissioning and vacuum performance factors.
• Systems Engineering
  • Working with both internal technical staff and external partners to deliver integrated solutions that meet all requirements.
  • Resolving technical issues, ensuring that the demonstration systems are operational and reliable.
  • Leading/defining trade studies
  • Developing systems requirements & specifications
  • Leading/defining design reviews
• Work with the team on fabrication oversight, installation, commissioning and operation of the CEBEX experimental system.
  • Writing statements of work for procurement of necessary materials.
  • Managing projects to value engineering on a tight budget and schedule.
  • Coordinating with Project Manager to provide input to schedule updates and reporting as necessary.
  • Engaging with vendors, contractors, supply chains.
  • Support installation and acceptance of the demonstration system.
  • Manage experiments on the demonstration system.
  • Write daily logs and reports on the state of the demonstration system.
• Process measurements, ensure reliable data acquisition and interpretation, including but not limited to:
  • Characterizing material samples with defined surface finishes and/or functional coatings.
  • Operating ultra-high vacuum (UHV) systems e.g. X-ray Photoelectron Spectroscopy (XPS) and Secondary Electron Yield (SEY).
  • Preparing written reports, and presenting results in technical meetings and associated reviews.
  • Monitoring and maintaining the performance of measurement equipment including required calibrations.
• Other duties as assigned.

Basic Qualifications

• 8+ years of experience in vacuum science or vacuum engineering,
• BS in Physics, Mechanical, Aerospace, Chemical or Systems Engineering;
  Material Science; or a related scientific or engineering field.
• 3-5 years workplace experience in developing system requirements and performance objectives for bids, quotes, etc.
• Basic understanding of surface science methods and instruments and their utility.
• 3-5 years post-education workplace experience with high-level workbench software such as ANSYS or COMSOL.
• Demonstrated 3-d modeling skills are a plus. Solid Works is preferred.
• 3-5 years post-education workplace proficiency in MATLAB, Mathematica, or Python, Office 365.

Preferred Qualifications

• Masters in Physics, Mechanical, Aerospace, Chemical or Systems Engineering;
  Material Science; or a related scientific or engineering field
• Knowledge of ultra-high vacuum (UHV) production, measurement, and analysis.
• Experience with large vacuum systems such as space simulation, beamlines, colliders or thermal-vacuum chambers.
• Ability to specify UHV equipment to achieve system requirements.
• Experience in defining materials and fabrication techniques to be used in vacuum construction, particularly UHV compatible materials, processes, and welding.
• Experience with Instrument control such as Lab View.

Required Documents
