Mechanical Engineer (Dynamics Analyst)


The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, located midway between Baltimore and Washington, DC is seeking a Mechanical Engineer (Dynamics Analyst).

Job Summary: Contribute in a multidisciplinary team environment to key technical efforts in the areas of modeling and simulation of dynamical and vibratory systems, shock and vibration test and analysis, modal analysis and system identification, digital signal processing, and structural dynamics.

Duties (Listed in order of importance with the estimated amount of time spent at each task):

1.(30%) Develop simulation models of dynamical and vibratory systems using first principles, commercial structural analysis codes, and available test data. Generate and use digital signal processing algorithms for data analysis and data products.

2.(20%) Work with structural analysts to develop and integrate high-fidelity, FE-derived structural dynamics models into analytical dynamics and/or systems-level simulations.

3.(10%) Support shock & vibration test planning, data acquisition, and modal survey activities.

4.(15%) Be a thought leader on dynamics- and vibration-related problems and technical lead of small, multi-disciplinary teams to achieve program goals. Proactively seek opportunities for collaboration across APL organizational boundaries and with external customers. Identify opportunities for new and high-value work.

5.(15%) Document technical contributions in internal memoranda, reports, and presentation packages and conference/journal papers, as appropriate. Present findings and recommendations at appropriate internal and external forums.

6.(10%) Actively participate on industry/government Integrated Product Teams. Provide technical expertise and independent review of test and analysis activities. Interact with program and project managers, sponsors, contractors, and other APL staff as appropriate.

Note: This job summary and listing of duties is for the purpose of describing the position and its essential functions at time of hire and may change over time.

Required Qualifications:

M.S. in engineering, physics, or related degree with 1 year of analytical dynamics and mechanical vibration principles and experience with first-principles modeling and simulation of single- and multi-body dynamical systems or equivalent relevant coursework. Proficiency in a scientific computing language, such as Matlab. Relevant problem-solving experience in dynamics, mechanical vibration, and shock. Must be willing to work with technical staff to solve complex problems in a team-oriented, multi-disciplinary environment. Strong organization and planning skills. Excellent written and verbal communication skills. Must have ability to obtain a Secret clearance.

Desired Qualifications:

Ph.D. in engineering, physics, or equivalent experience. Demonstrated ability to use analytical, empirical, and computational tools to solve complex problems. Applied engineering experience. Proficiency in Matlab/Simulink and ADAMS. Familiarity with C or FORTRAN. Knowledgeable in computational mechanics and the Finite Element Method. Working knowledge of a commercial finite element code, especially ABAQUS or NASTRAN. Experience with data acquisition, modal analysis, and digital signal processing. Record of accomplishment in a team environment. Current Secret or Top Secret security clearance.

Special Working Conditions (travel, working in closed areas, extended hours): Must be willing to travel for occasional testing and meetings at off-site sponsor/contractor facilities.

Security: Applicant selected will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.

Benefits: APL offers a comprehensive benefits package including a liberal vacation plan, a matching retirement program, significant educational assistance, a scholarship tuition program for staff with dependents, and competitive salaries commensurate with skills and experience.
