Description

ARA’s Engineering Science Division is seeking an experienced mechanical engineer to support the design, development, prototyping, integration, and qualification of complex mechanical systems. The successful candidate will be a hands-on mechanical engineer who can move comfortably between computer-aided design (CAD), engineering analysis, prototyping, system-level reviews, and hardware integration. You should be comfortable working in a collaborative, technically demanding environment and communicating engineering decisions to both technical and non-technical stakeholders.

This is an on-site position in the ARA office in Panama City, FL. Hybrid work may be possible for the right candidate, requiring attendance in the office a minimum of 3 days per week. This position also requires regular travel to Newport, RI (up to 15%).

What you will do as a senior mechanical engineer:

• Design, develop, test, handle implementation, and analysis of technical products and systems using applied engineering principles, including solid and fluid mechanics, and heat transfer
• Perform engineering design evaluations on weapons systems
• Perform dimensional tolerance analysis and functional analyses
• Procure, assemble, and test advanced prototypes to inform design decisions, refinements, and to demonstrate performance
• Prepare and present designs, at various design reviews
• Assist in the development of requirements for hardware
• Ensure designs satisfy requirements and demonstrate performance in a thorough verification and validation program
• Analyze data and make recommendations for improvement
• Understand nominal and off-nominal operations for a technical system and its interaction(s) with other systems
• Manage multiple issues at one time and develop an integrated solution
• Work with fabrication and manufacturing departments to ensure final design is properly executed in the creation of mechanical products
• Be agile and willing to assist in all areas of the development process to meet project milestones

Senior mechanical engineer requirements:

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or related field
• 8+ years of related work experience; graduate degree/research may serve to partially fulfill the experience requirement
• Excellent verbal, written, interpersonal, leadership, and team working skills
• Demonstrated skill in using CAD and computational fluid dynamics (CFD) modeling software in design work
• Demonstrated experience in design analysis and mechanical design requirements development
• Ability and willingness to travel as required
• Ability to obtain a DoD Secret clearance; active Secret clearance is highly desired

Preferred capabilities:

• Strong background in thermodynamics, fluid dynamics, heat transfer as applied to high-pressure, high-temperature systems
• Proficiency with CFD for compressible, high-temperature, high-pressure flow
• Ability to conduct static and dynamic structural finite element analysis (FEA) including thermal stress, pressure loading, vibration, and shock response
• Experience with thermo‑mechanical coupling to evaluate stresses resulting from rapid pressure and temperature transients
• Knowledge of material behavior under elevated temperatures, high strain rates, cyclic loading, and thermal fatigue
• Ability to correlate analytical models with experimental test data, identify model uncertainties, and improve predictive accuracy
• Experience developing first‑principles engineering calculations to validate numerical simulations and support design decisions
• Experience interpreting high‑speed instrumentation data, including pressure, temperature, strain, and acceleration measurements
• Understanding of reliability engineering, failure analysis, and root cause investigation
• Strong cross‑functional communication skills, with the ability to collaborate across mechanical, materials, manufacturing, and test engineering teams
• Demonstrated ability to take complex engineering concepts from analytical modeling through prototype testing and production implementation
• Understanding or previous experience in the Undersea Warfare domain
