Job Summary

The Detector Electro-Mechanical Engineer will work with the Detector Engineering Group to ensure that the Laser Interferometer Gravitational Wave Observatory (LIGO) detector functions consistently to accomplish its scientific mission. Perform mechanical engineering for the full life cycle of the project – from research and development to manufacture and maintenance. Design, engineer and develop optical, mechanical and/or the associated instrumentation of the detector, with a focus on the seismic isolation system.

Job Duties

  • Support the scientific mission by tracking, and resolving issues arising with the detector, including related hardware and software. Log faults and update work progress with the appropriate reporting tools. (20%)
  • Establish and maintain expertise in the LIGO detector's various systems and components, especially opto-mechanical and their associated instrumentation, taking initiative to improve diagnostic and operational methods. Install, calibrate, and use precision sensors for monitoring and controlling the position, alignment, and vibration level of isolation platforms, suspended optics and optical cavities. He will test and characterize, the many dynamical systems, including the multistage isolation platforms. (20%)
  • Propose, plan, budget and implement needed changes and improvements to various detector systems. Oversee mechanical design projects from conceptual to integration phase through procurement, installation and commissioning. (10%)
  • Lead projects related to control design, including design and optimization of various feedback and feed forward control loops, in phase with specific needs of the instrument.  Design, diagnose, characterize, commission, optimize and maintain performance of the detector's control loops. (20%)
  • Maintain and improve various noise and performance models, in close collaboration with LIGO's commissioning team and others. Develop and manage characterization tests to validate, monitor and document the operability, performance and stability of the system. Assist the commissioning and scientific team to improve the detector's sensitivity and duty cycle. (20%)
  • Maintain detector configuration and performance documentation, and prepare reports for LIGO's system engineering group and/or for publication. Write technical reports and procedures. Document and present scientific results at group meetings and conferences. (10%)

Above duties require up to 25% travel – i.e., 12 weeks per year (60 work days) to work at other LIGO locations (Pasadena, CA; Richland, WA) and for LIGO meetings at MIT (Cambridge, MA).

Required Documents

  • Master’s or equivalent degree in Mechanical Engineering or a related field and 3 years of experience in the job offer, or in an engineer position that required design, characterization or operational maintenance of precision optical, mechanical and/or instrumentation systems. Will also accept a Ph.D. or equivalent degree in Mechanical Engineering or a related field with 1 year of experience in the job offer, or in an engineer position that required design, characterization or operational maintenance of precision optical, mechanical and/or instrumentation systems
  • Requires 1 year of opto-mechanical engineering including signal processing, data analysis, feedback control modeling, modal analysis modeling and testing with Matlab, contamination control and laser safety protocols, and expository and scientific technical writing
  • Requires up to 25% travel – i.e., 12 weeks per year (60 work days) to work at other LIGO locations (Pasadena, CA; Richland, WA) and for LIGO meetings at MIT (Cambridge, MA)
  • Must be authorized to work full-time without employer sponsor
  • Resume
