Job Description
The Lead Mechanical Engineering (Analyst) is responsible for directing and executing structural thermal and opto-mechanical analyses in support of the development of high-performance opto-mechanical systems such as telescopes beam directors and related instruments and subsystems.
Primary Duties & Responsibilities
This role spans the development of precision structures mechanisms and optical support assemblies for platforms ranging from terrestrial to spaceborne. The analyst performs detailed stress thermal and dynamic assessments using both closed-form methods as well as advanced finite element techniques and leads the characterization of optical performance in demanding thermal and vibrational environments. Responsibilities include ensuring system survivability alignment and optical performance under operational and survival loads preparing comprehensive analysis reports developing structural test requirements and supporting environmental testing campaignsincluding dynamic and thermal verificationto validate analytical predictions and confirm compliance with system requirements.
- Perform and lead detailed structural thermal and dynamic analyses of opto-mechanical systems
- Develop and validate finite element models for stress steady state and transient thermal modal random vibration and shock analyses (Femap with NX/Nastran and/or SimCenter 3D preferred)
- Use closed-form methods to provide quick-turn assessments and to validate FEA results
- Characterize operational and survival loads (thermal cycles random/sine shock launch wind seismic) predict system response assess structural integrity and stability
- Conduct STOP analysis to characterize optical performance (e.g. wavefront error line-of-sight jitter alignment stability); experience with preparing results for processing with optical analysis software such as Code V or Zemax using Sigfit or Matlab preferred.
- Prepare and deliver analysis reports and design review documentation (PDR CDR)
- Develop structural and thermal test requirements to validate analytical predictions
- Support environmental testing campaigns (vibration shock thermal thermal-vacuum) including test planning data correlation and anomaly resolution
- Contribute to risk assessments and design trades recommending design modifications based on analysis outcomes
- Collaborate closely with design engineers optical engineers systems engineers and test teams to ensure requirements compliance
- Mentor less experienced engineers in analysis tools methods and best practices
Education & Experience
- Typically requires a Bachelors degree in Mechanical Engineering. An understanding of precision mechanism design and/or opto-mechanical design principles as well as hands-on hardware assembly integration and testing are essential.
- Minimum 7 years of related experience in a professional role with a bachelors degree in Optical Sciences or related discipline; or minimum of 5 years of experience with a masters degree or 3 years of experience with a doctorate in a relevant field.
Skills
- Expertise in finite element analysis (FEA); Femap with NX Nastran or SimCenter 3D preferred
- Strong knowledge of structural mechanics heat transfer and dynamics as applied to precision opto-mechanical systems; experience with Computational Fluid Dynamics (CFD) is a plus
- Experience with thermal-structural coupling and integrated opto-mechanical performance characterization; experience with Sigfit a plus
- Familiarity with optical performance metrics (wavefront error jitter line-of-sight stability) and their mechanical drivers
- Proficiency in environmental loads analysis (thermal environments random vibration acoustic shock seismic wind)
- Ability to correlate analysis with test data and refine models based on measured results
- Knowledge of materials selection for precision structures (aluminum steel invar ceramics structural adhesives etc.). Familiarity with composites is a plus.
- Strong technical writing skills (analysis reports and design review documentation)
- Effective communication and teamwork skills for cross-discipline collaboration
Working Conditions
- Job operates in a professional office environment
- Routinely uses standard office equipment such as computers phones photocopiers filing cabinets and fax machines
- Work in a cubicle office
Physical Requirements
- Walk. Occasionally move about inside the office to access file cabinets office machinery etc.
- Talking. Expressing or exchanging ideas by means of the spoken word. Those activities in which they must convey detailed or important spoken instructions to other employees accurately loudly or quickly.
- Hearing. Perceiving the nature of sounds at normal speaking levels with or without correction. Ability to receive detailed information through oral communication and to make the discriminations in sound.
- Use hands/fingers to type/handle. Operating a computer and other office productivity machinery such as a calculator copy machine and computer printer.
- Sedentary Work. Sedentary work involves sitting most of the time. Jobs are sedentary if walking and standing are required only occasionally and all other sedentary criteria are met.
