Title: Senior Electronics Engineer

Type: Full time

Location: GMT Project Office, Pasadena CA

Background:
This exciting job opportunity is with the GMTO (Giant Magellan Telescope Organization) located in Pasadena, California. The GMT is being developed by a group of leading university and research centers from across the globe. The GMTO Corporation has been formed to design, construct and operate the GMT Observatory which will be located in the Andean mountains at Las Campanas Peak in Chile. The GMT is the next generation astronomical observatory with the capability to have 10 times the resolution of the Hubble Space Telescope. The project is entering the formal construction phase with scientific operations expected to begin in 2021-2022.

BE A PART OF TRANSFORMING OUR UNDERSTANDING OF THE UNIVERSE

The successful candidate will be an employee of the GMTO Corporation and must be able to meet pre-employment requirements including any background and reference checks and the successful candidate must be a US citizen or eligible to work in the United States and at least 18 years of age. GMTO provides competitive salaries and a generous benefits package.

Job Summary:
The GMT project is seeking a Senior Electrical Engineer to assist in the development and procurement of the electrical systems for the Primary Mirror Subsystem of the GMTO. The successful candidate will work with a small team of engineers to design, procure, integrate, and test the electrical control system for actuator and position sensing subassemblies that are a part of the GMTO primary mirror segment support and control system. The Senior Electrical Engineer must be experienced in working with multidisciplinary teams that have successfully delivered complex, high-precision electro-optical systems. The Senior Electronics Engineer will manage the requirements, design, and procurement of mirror cell subassembly components. He will also be responsible for the integration of these into the mirror cell subassemblies and the testing of the cell subassemblies in the mirror cells.
The Senior Electronics Engineer will work with GMT System Engineering and other teams to document the flow down of requirements into the design of electromechanical devices and produce verification methods for their performance. The position will provide detailed requirements for sensors, actuators, drivers and controls systems for closed-loop operation. The engineer will provide hardware specifications for motion control architectures and their performance characteristics.
This position will also require the elaboration of Failure Modes and Effects Analysis (FMEA) regarding the components of the system and the development of lists of preferred hardware (drivers, controllers, actuators, sensors, connectors, cable types, hoses and coolant lines, chasses and distribution panel hardware).

The Senior Electrical Engineer will help design and test a variety of control circuits that will use load cells, thermocouples, pressure sensors, accelerometers, and linear gauges for high accuracy control of very large optics. Experience in the detection of low-level sensor signals is needed in this position. This role will also support the design of the electronic aspects of the thermal control system and the thermocouple temperature measurement system which is required to reduce thermal gradients in the Primary mirrors.

The candidate will be responsible for the design of monitoring and safety systems that will help protect the large 8.4m mirror segments. This includes the testing of subsystems, test data collection, and the design of mirror cell telemetry.
Experience writing technical reports, requirements documentation, and statements of work are desired skills in this position. This person will be responsible for making presentations at project meetings, reviews, and conferences.
The Senior Electronics Engineer will prepare cost estimates and schedules for the development and implementation of the M1 subsystem for inclusion in the project budget and schedule.

Job Duties:
• Flowing down and specifying detailed requirements for the sensors and actuators, such as, accuracy and precision, bandwidth, stiffness, rejection of disturbances, robustness and stability
• Managing and documenting the specifications and design of the actuators, sensors and control hardware for the primary mirror
• Developing detailed manufacturing documents and drawings for the components
• Managing the procurement process of the components, meeting time and cost budgets constraints
• Implementing and managing the quality assurance process of the manufacturing, test and integration of the components
• Developing test and verification plans and procedures
• Being the technical point of contact between GMTO and contractors or other support groups
• Prepare cost estimates and schedules for the development and implementation of the M1 subsystem for inclusion in the project budget and schedule
• Preparing status reports for inclusion in project reports
• Monitoring the integration and shop assembly of sensors, actuators and control hardware, at contractor facilities and in the GMT site in Chile

Essential Skills, Knowledge, and Abilities:
• A BS in Electrical or Electronics Engineering or electro/mechanical engineering, or closely related degree with 10 years of relevant experience with electro/mechanical systems on complex technical projects
• Hands-on experience and expertise in planning and implementing the overall design for motion control systems, servo actuators for high precision and complex electro/mechanical systems
• Ability to grasp the concepts to successfully integrate controls hardware and electronics into sealed thermal enclosures with heat removal capabilities
• Demonstrated leadership, organizational, and management skills
• Ability to prepare documents, reports, and oral presentations
• Previous experience developing test and verification procedures and plans on complex systems
• Demonstrated skill with software for board designing and SolidWorks or other software to layout wiring diagrams, cabling and connectors
• Demonstrated success in working with multidisciplinary teams that have successfully delivered complex, high-precision electro-optical systems.
• Knowledge of standards and current practices in this area of expertise, familiarity with Safety of machinery standards (ISO 13849) and robot safety requirements (ANSI R15.06)
• Flexibility to work outside of core business hours and travel to GMTO member locations, vendor premises and the GMT site in Chile when necessary to accomplish goals. Ability to work at an altitude of 8000 feet for extended periods

Desired Skills, Knowledge, and Abilities:
• An MS degree in Electrical or Electronics Engineering or electro/mechanical engineering, or closely related degree with 10 years of relevant experience with electro/mechanical systems on complex technical projects
• Experience with ground-based telescopes or other large electro-mechanical/optical systems
• Experience in the detection of low-level sensor signals
• Experience with sub-micron motion control systems
• Demonstrated ability to integrate controls hardware and electronics into sealed thermal enclosures with heat removal capabilities
• Demonstrate ability to use SolidWorks to layout wiring diagrams, cabling and connectors
