The Giant Magellan Telescope Primary Mirror (M1) comprises seven 8.4-meter mirror segments, which must be positioned and controlled to function as a 25-meter aperture telescope. The M1 Subsystem supports and positions the individual mirror segments and provides the means to actively adjust the positions of the mirrors, deform their reflective surfaces to the desired shapes, stabilize the temperatures of the mirror substrates, and protect the mirrors in the event of an earthquake. M1 Subsystem components are integrated into steel weldments delivered by the Telescope Structures Element. The M1 glass mirror segments are delivered by the Optics and Opto-Mechanics Element. Together, the weldments, mirror segments and the M1 Subsystem comprise the M1 mirror cells.
The M1 Subsystem (M1S) Deputy Element Manager (DEM) will support the M1S Element Manager in the development of the GMT M1S including leading incorporation of lessons learned into the design, preparing for the final design review (FDR), conducting the FDR, and overseeing prototype testing. The DEM role will involve production planning, source selection, planning of assembly, integration, verification, and commissioning (AIVC), and overseeing production and AIVC of the M1S. Deliveries will include the subsystem components for eight primary mirror cells, AIVC of four telescope mirror cells at both the mount supplier and the GMT site in Chile, and commissioning of the M1 systems at the observatory.
DEM management responsibilities include recruitment, internal organization, contract management, and leadership of a team of subject matter experts within GMTO and among various consultants and subcontractors needed to perform the engineering tasks. Contract management will include defining work packages, identifying vendors and/or groups capable of completing the work, generating statements of work and technical specifications, participating in contract bid/selection processes, monitoring contracted work through completion, and establishing acceptance procedures.
The M1S DEM reports directly to the M1S Element Manager. The M1S DEM position will require a combination of engineering expertise and management ability. He/she will be responsible for assisting the M1S Element Manager in developing the schedule and budget plans for the M1 Subsystem, and in executing this plan in an earned-value management framework of project controls, including assessment of cost and schedule variances, implementation of appropriate response actions to stay on plan, and risk management.
The M1S DEM will work with the GMT Project Systems Engineer on requirements development, interfaces, operations concepts, and verification and validation; with the M1S Chief Engineer to assure that best practices and lessons learned from other telescope projects are incorporated, and to address seismic design aspects; with the Safety and Assurance Leads to incorporate appropriate safety and quality assurance aspects; with the Telescope Structures Element to coordinate the design of the mirror cell weldments; with the Optics and Opto-Mechanical Element to assure proper interface and safe control of glass mirror segments and the telescope metrology system; with Wavefront Sensing & Control Element to assure that the M1 Subsystem properly performs its role in the wavefront control and phasing of the telescope; and with the Integration & Test lead to develop the final integration, test and commissioning plans.
