Job Description

Description

SAIC is seeking a Senior Mechanical Engineer on the OMES II contract in support of the NASA’s Exploration and In-Space Services (NExIS) projects division at NASA Goddard Space Flight Center. This position is located in Greenbelt, MD.

The OSAM-1 mission is a Goddard Space Flight Center (GSFC) Satellite Servicing Project Division (SSPD) managed mission. OSAM-1 is a robotic servicing mission designed to refuel a Low Earth Orbit (LEO) satellite. It contains 3 elements: the Flight Element comprised of the OSAM-1 Servicing Vehicle (RSV) and development testbeds, the Ground Element comprised of the systems required to conduct RSV operations and the supporting networks and facilities, and the Launch Element comprised of the Launch Vehicle and supporting facilities and services. The SSPD is responsible for the design, engineering, development, test and operations of the OSAM-1 Mission through an integrated team at GSFC. The Servicing Payload design, development and RSV integration will be conducted at GSFC.

JOB DESCRIPTION:

Job duties include:

  • Perform design, analysis, and test of complex materials, structural components, functional systems, and tool assemblies for both engineering unit and flight hardware
  • Respin engineering unit tool designs for flight, including selection of appropriate flight materials, design updates, testing, etc.
  • Develop original tool designs and elaborate on or update preliminary and legacy design concepts
  • Evaluate completed designs with team members and management and make modifications necessary to achieve the most ideal design
  • Develop and coordinate test programs required to evaluate design work, engineering unit hardware, and flight hardware
  • Support the design and fabrication of the mechanical ground support equipment (MGSE) to safely handle critical and flight hardware
  • Work in lab and cleanroom facilities with hardware, ground support equipment, and test equipment
  • Ensure that the quality, accuracy, and integrity of your technical documentation, reports, and deliverables comply with NASA and OSAM-1 standards, project plans, and policies

Qualifications

REQUIRED EDUCATION AND EXPERIENCE:

  • Bachelor’s degree in mechanical engineering, or closely related field with 15+ years of related experience
  • Practical experience using advanced principles, theories, concepts, and techniques in solving mechanical engineering problems, with the ability to perform trade studies, develop conceptual configurations, engineer piece-parts and mechanical systems, and facilitate the fabrication, assembly, and qualification of MGSE and flight hardware
  • Expertise in mechanical engineering disciplines for the design, analysis and test of tools and mechanisms, including engineering mechanics (statics and dynamics), strength of materials, structural design, machine design, structural/mechanical testing, manufacturing engineering, mechanical systems, and machine shop practices
  • Experience developing and delivering mechanical hardware, assemblies, and mechanical systems
  • Practical experience using PTC CREO, or equivalent CAD software. Experience with CREO mechanism modeling module is a plus.
  • Firm grasp and understanding of ANSI drafting and tolerance standards
  • Ability to create and tolerance individual piece-parts and assembly drawings 
  • Understanding of advanced fabrication and manufacturing methods
  • Strong communication skills and ability to interface with and lead multi-disciplinary teams of engineers, analysts, designers, manufacturing specialists, machine shop, flight techs, and project staff

DESIRED EXPERIENCE:

  • Knowledge of NASA mechanical/mechanism design criteria and standard practices
  • Proficiency with all aspects of flight hardware and mechanism development including requirements and ConOps definition, design, analysis, prototyping, drafting, procurement and fabrication, procedure development and execution, assembly and test, launch vehicle integration and mission operations support
  • Knowledge of materials, treatments, and coatings related to space-flight design and operation of mechanisms 
  • An advanced working knowledge of space flight mechanisms with a focus on: actuators, motors, power transmission, bearing/shaft design, electro-mechanical mechanisms, stored energy devices and tribology
  • Hands-on experience in mechanical integration of spacecraft flight systems, especially in a clean room and/or high bay. Established proficiency working in a Class 10,000 (ISO 7) cleanroom, and proper handling/assembly of mechanisms and fluid systems in a Class 1,000 (ISO 3) facility or flowbench; development of full cleanroom specifications and outfitting of I&T facilities to support hardware builds
  • Experience with Configuration Management Systems (TDMS, Windchill, equivalent)
  • Knowledge of mechanical design as it relates to 1-G mechanism development, testing, and operations 
  • Demonstrated experience with space robotics, vision systems, end-effectors, and tools including experience with proven optical/visual feedback elements for control of mechanisms and alignment of interfaces for in space non cooperative clients
  • Proficient knowledge of robotic feedback systems and controls and their impact on mechanisms design and compliance; experience in developing design solutions for rigid and compliant interfaces
  • Environmental testing experience (thermal, vibration, shock) as it relates to verification and validation of ground and space-flight hardware 
  • Knowledge of General Environmental Verification Specification (GEVS) and NASA 5017
  • Working knowledge of materials, coatings, and related processes as it applies to space-flight hardware
  • Practical knowledge of Standards for Geometric Dimensioning and Tolerancing (GD&T)
  • Experience planning for and leading complex mechanical integration activities.
  • Experience writing assembly and test procedures, process requirements, and mechanical hardware requirements including the production of procedures for processing of mechanisms including cleaning, handling, inspection and lubrication
  • Experience with NASA mission life cycle and review cycle (.design reviews, requirements reviews, integration reviews, trade studies, etc.)
  • Experience in flight hardware supply chain management and procurement management, expediting, inspection and disposition and logistics of preparing a system-level flight hardware build
  • Experience in robotic and blind-mate cooperative spacecraft refueling couplings including seal design, alignment features and compliance mechanisms, and the unique tooling and assembly conditions required; commensurate experience in pressure systems design and fluid systems certification testing
