Job Description

Summary

This job involves designing and building specialized mechanical equipment and tools to support intelligence operations at the NSA, including creating custom parts, running tests, and solving technical problems for quick prototype projects.

It's a great fit for recent engineering graduates or those with a few years of hands-on experience in mechanical design who enjoy using software to model and analyze systems.

The role requires strong problem-solving skills and attention to detail in a secure government setting.

Key Requirements

  • Bachelor's degree in Engineering (preferably Mechanical) or a related technical field like physics or computer science, with ABET accreditation or specific coursework in calculus and engineering sciences
  • For entry level: No experience required with an Engineering degree, or 1 year of relevant experience with a related degree
  • For full performance level: Bachelor's plus 3 years, Master's plus 1 year, or Doctoral with no experience in mechanical design engineering
  • Proficiency in 2D/3D CAD software for designing parts and mechanisms
  • Experience with engineering analysis tools like CAE for thermal, stress, and vibration simulations
  • Knowledge of mechanical principles including properties of materials, heat transfer, tolerancing, and prototyping processes
  • Ability to perform calculations, develop test plans, and identify manufacturing techniques to solve prototype design problems

Full Job Description

Create the systems & tools that will be used to enhance the operation of intelligence.

You will advise, administer and perform scientific projects, such as planning, designing, and constructing specialized equipment, and ensuring adherence to sound engineering and scientific standards and principles.

Major Duties:

The NSA currently has opportunities for highly motivated Mechanical Design Engineers to support design, analysis and fabrication of mechanical hardware and equipment in response to limited quantity, short-duration, prototype requirements.

As a Mechanical Design Engineer at NSA, responsibilities may include: - Design custom parts, mechanisms and equipment. - Perform engineering calculations.

- Analyze problems to determine technical solutions. - Decide what procedures will be required to solve technical problems. - Develop conceptual designs or models to address requirements.

- Use modeling or simulation software to evaluate designs. - Perform engineering analyses and testing of products/parts/equipment.

- Use Computer Aided Design (CAD) software and Computer Aided Engineering (CAE) (thermal/stress/vibration analysis tools) to produce design drawings and to validate and support engineering design activities.

- Identify new and existing products, technologies, and/or manufacturing techniques to solve design, development, and operational problems.

- Develop engineering test plans to evaluate designs in real-world environment prior to operational use. - Modify or adapt products, services, and support to meet customer needs.

- Provide timely and accurate responses to customer requests for assistance, information, products, or services.

- Work with customers to clarify their needs and to determine how their needs can be met expeditiously.

- Work on teams with engineers and fabricators of various disciplines and levels to meet customer mission needs.

Work is in a very fast paced office which requires employees to work on multiple projects simultaneously with quick turn-around schedules.
