Since FAPESP entered the GMT Project and since the creation of the GMTBrO (GMT Brazil Office), we've been trying to collaborate with other members on the conception of the instruments to be installed in Giant Magellan Telescope (GMT). For the GMACS Spectrograph the chosen candidate will be trained in the Instrumentation and Systems Engineering areas. This professional will establish a link between the technical and scientific parts of the project, having, furthermore, a general vision of the project, he will do the interface with all the mechanical and optical engineers (based in Brazil and USA), the software group (which has its base in South Korea) and the electronics group, without losing contact with the science group. He will work as a team member at University of Sao Paulo and at Texas A&M University.The GMACS is a wide field spectrograph which will be operational at first light on the GMT. It will have two arms, the blue one and the red one, capabilities of doing spectroscopic observations with moderate-resolution. It will observe exoplanets and additionally stars in other galaxies and galaxies in the distant Universe.A systemic approach has been increasingly used in Engineering projects development. In this approach, a project is conceived with Systems Engineering methods, using the concept of life cycle, where we plan all the phases of the system's life, since the need for its construction till its deactivation. In the system's development phase it is used the concept of top-down development: we start from the system's requirements and after that there is the development of the subsystems requirements and other lower hierarchical levels until the level of the components or of those directly acquired off the shelf. This approach was, during decades, used only in large military and space projects and it proved to be very well suited for ensuring success in the development and for achieving goals in terms of deadlines and costs.The GMTO, which is GMACS development sponsor, follows a Systems Engineering approach in the Telescope's development and also recommends this approach in the development of the Telescope's instruments, specifically for the GMACS instrument. In fact, in order to increase chances for success, it is fundamental for the project's team to understand the importance of identifying and managing the instrument's requirements and thus avoiding bad surprises along the project.GMTO defines the following life cycle phases: concept, preliminary project, detailed project, fabrication, integration, tests and commissioning, operation, deactivation. The conceptual design phase will have a 19 months duration, starting from September 1st, 2016. The operation phase is scheduled to start in 6 years and it will last up to 20 years.The following specific tasks are fixed for the concept phase:1.To collaborate in the preparation of the scientific requirements for the GMACS instrument.2.To collaborate in the determination of the GMACS instrument's functional and performance requirements.3.To collaborate in the determination of the GMACS instrument's modes and states.4.To collaborate in the preparation of the document of the GMACS instrument's operation5.To identify the GMACS instrument's control and command software requirements.6.To identify the GMACS instrument's software user interface.7.To identify the GMACS instrument's data processing software requirements.8.To collaborate in the preparation of the GMACS requirements documents.9.To get familiar with the software requirements.10.To maintain a good relationship with those responsible for developing the Observatory's software.11.To prepare the specification of the GMACS software requirements.12.To collaborate in the preparation of analyses, studies, models, reports.13.To collaborate in the trade-off analyses of the possible solutions for the GMACS instrument.Publications in instrumentation magazines are expected to happen.
