Position Location: 
MCDONALD OBSERVATORY
Job Description: 

As part of the Hobby-Eberly Telescope (HET) Optics Team, the HET Mechanical Engineer will lead or participate in the mechanical design relating to optics and managing the optical maintenance. This position will participate in all activities in the HET optics lab including the maintaining the reflectivity of the primary mirror segments, and operating and maintaining the mirror coating facility. In addition, this position will work closely with colleagues at the HET and in Austin to design, build, and maintain optomechanical tools and instrumentation as needed for the efficient operation of the HET.

Job Details:

General Notes - This position is located at McDonald Observatory, 16 miles from Fort Davis, Texas (440 miles away from the UT Austin campus). The Hobby-Eberly Telescope (HET) operates on a 24/7/365 day schedule. This position will be expected to respond to failures and business needs, relating to the telescope or observatory, outside of normal work hours (nights, weekends, and holidays). Candidates selected for on-site interview will be required to demonstrate the ability to perform the optomechanical physical tasks including climbing ladders, stairs, and a lattice shell structure; moving mirror maintenance equipment; wearing fall protection equipment; and assembling/disassembling mechanical components.

Residence in the Observatory's residential community may be available and may be required. Position may be subject to “call-back” as an essential employee for emergency or critical response.

Responsibilites

  • Leads or participates in projects to improve the performance of the telescope from a mechanical and/or optomechanical perspective. Such projects may include both mechanical and optical design from first principles to an operational instrument, tool, or fixture.
  • Maintains all optics and optomechanical subsystems on the HET with emphasis on the reflectivity of the HET primary mirror segments, the overall optical throughput of the telescope, the performance of the primary mirror Segment Control System (SCS), the primary mirror Segment Alignment Measurement System (SAMS) and the Center of Curvature Alignment System (CCAS).
  • Works with the optics team to operate and maintain the 15kW, 10,000V, E-Beam mirror coating system to coat 1-meter hexagonal mirror segments with aluminum. This includes all vacuum equipment, ion assisted vapor deposition system, and optical coating metrology instrumentation. Operates and maintains the class 10,000 clean room housing the mirror coating facility and the Strip and Wash (SAW) room where the 1-meter segments have old coating removed and are prepped for the new coating.
  • Investigates and solves telescope failures or performance deficiencies related to optomechanical and electro-optical subsystems on the telescope.
  • Works closely within the HET Optics Team and with Operations Management to provide leadership as needed in defining and scheduling all optics team activities. Participates in weekly meetings or work sessions.
  • Other related functions as assigned.

Required Qualifications

  • Master's Degree in Mechanical Engineering with two years work experience in related field or Bachelor's Degree in Mechanical Engineering with four years experience in related field.
  • Understanding of system level interactions between mechanics, optics, electronics and software to enable effective problem solving and troubleshooting at the system level down to the individual part level.
  • Experience with mechanical design using Solid Works, Inventor, or similar solid modeling CAD packages.
  • Basic fabrication skills using tools for material cutting, drilling, milling, and turning.
  • Self-driven individual with keen technical ability, systematic approach, detailed-oriented, excellent theoretical and hands-on problem-solving skills, positive attitude, strong work ethic, and strong team player.
  • Demonstrated problem solving ability, including designing of experiments and carrying out tests to collect and analyze data.
  • Has excellent technical writing and documentation skills.
  • Excellent interpersonal, oral, and written communication skills and the ability to interface with all levels of staff and leadership.
  • Relevant education and experience may be substituted as appropriate.

Preferred Qualifications

  • Master’s Degree in Mechanical Engineering with more than five years related experience.
  • Experience with optical coating processes, more specifically ion assisted electron beam vapor deposition, and the process control requirements that lead to optimal coating performance in terms of reflectivity and durability.
  • Experience with vacuum system operation and maintenance for optical coating processes.
  • Proficient in mechanical and optomechanical design using Solid Works and/or Inventor.
  • Basic optical design experience and some exposure to optical design/simulation tools such as ZEMAX and/or optical system performance measurement.
  • Hands on experience in optical component mounting, interfaces and adhesive bonding.
  • Experience with cleaning and handling optical components.
  • Experience in statistical process control (SPC)
  • Practical programming experience (Python, MATLAB or equivalent).
