About the Job

Requirements

  • A bachelor's degree in Mechanical Engineering, Aerospace Engineering, Engineering Mechanics, Control Systems, or a related discipline from an ABET-accredited program and at least 12 years of relevant experience; alternatively, a graduate degree and at least 10 years of related experience; in lieu of a degree, at least 16 years of relevant experience.
  • At least 7 years of experience with computer-aided design modeling and design tools.
  • Prior or current experience with spaceflight mechanism applications.
  • At least 5 years of professional experience leading a multidisciplinary mechanical engineering team through system requirements, design, analysis, testing, hardware build, delivery, and launch.
  • Professional experience with finite element analysis and hand calculations.
  • Expertise in 3D modeling, design for manufacturing, and the ability to work independently or in a multidisciplinary team environment.
  • Ability to obtain and maintain a Top Secret/Sensitive Compartmented Information security clearance.

Responsibilities

  • Design, develop, analyze, and support manufacturing tasks for complex mechanical hardware, including precision space structures and mechanisms.
  • Support customer-funded programs and internal research efforts.
  • Provide technical leadership over requirements definition, concept generation, material and finish selection, trade studies, design sensitivity and optimization studies, preliminary and detailed design, sensitivity and tolerance analysis, design documentation, bill of materials management, and assembly, integration, and testing.
  • Design high-precision, complex space opto-mechanical telescope hardware as part of an Integrated Product Team, including machined components, composite structures, deployable mechanisms, opto-mechanical support structures, bearings, capital tooling and fixturing, and launch mechanisms.
  • Use high-reliability, flight-proven heritage design concepts to produce high-quality designs within aggressive timelines.
  • Lead and participate in technical team reviews and technical review boards.
  • Interface with suppliers, customers, and other engineering disciplines to drive designs to closure, including structural, thermal, electrical, manufacturing, integration and testing, quality, and configuration management.
  • Present design details at program reviews to customers and independent reviewers.
  • Develop and perform testing to demonstrate proof of concept and/or qualification of new designs.
  • Support production operations by designing tooling, test equipment, and shop aids.
  • Provide regular status updates to program management and project engineers on cost and schedule performance.
  • Establish and manage performance and error budgets for mechanism designs.
  • Perform mechanism sizing and torque margin calculations using applicable standards such as AIAA S-114A-2020 and/or NASA-STD-5017.
  • Design launch lock and restraint systems, including low-shock and foreign-object-debris-conscious solutions.
  • Select lubricants and materials suitable for spaceflight and contamination-sensitive optical environments.
  • Design hardware for vacuum, thermal extremes, cleanliness, and high reliability.
  • Create and maintain engineering documentation, including models, drawings, bills of materials, analyses, test plans, and reports.
  • Support root cause investigations, nonconformance resolution, and corrective action activities when needed.

Desired Qualifications

  • Strong proficiency in solid, surface, and assembly design and 3D modeling using Creo, NX, CATIA, SolidWorks, or Autodesk Inventor.
  • Proficiency with finite element analysis tools such as FEMAP, MSC Nastran, and/or ANSYS.
  • Experience with Halpin Engineering’s Orbis for bearing analysis.
  • Experience using MATLAB for analysis automation and data processing.
  • Proficiency in tolerance stack-up analysis for mechanical designs and geometric dimensioning and tolerancing.
  • Experience designing space-based mechanical structures, mechanisms, and electronics packaging, including engineering drawing development.
  • Experience building hardware in a high-reliability environment and working with technicians.
  • Experience interfacing with machinists and designing parts for ease of manufacturing.
  • Familiarity with component-, subassembly-, and assembly-level product testing.
  • Proficiency with root cause corrective action tools such as 5 Whys and fishbone analysis.
  • Proficiency with risk management and mitigation tools such as Failure Mode and Effects Analysis.
  • Experience serving on a Material Review Board to evaluate and disposition nonconforming hardware and develop rework and structural repair procedures.
  • Experience leading engineering teams from conceptual through detailed design phases.
  • Proficiency with product data management software and familiarity with configuration management best practices.
  • Familiarity with ISO 9000/AS-9100 Quality Management Systems, Lean Manufacturing, 5S, and Six Sigma fundamentals.
  • Proficiency in project management fundamentals, including budget, schedule, technical execution, and risk management; strong proficiency in Microsoft Project scheduling.
  • Experience training and mentoring new hires and junior engineering staff members.
