Senior Mechanical Engineer; Contingent

ARA is seeking a Senior Mechanical Engineer to support the design of equipment, tooling, and equipment interfaces for energetics chemical manufacturing systems and unmanned systems (UxS) programs supporting U.S. Government customers. This role spans a broad range of mechanical design applications, from process equipment and facility integration to mobile/field hardware platforms. The ideal candidate is an expert in Solid Works and AutoCAD, capable of taking concepts through detailed design and producing release‑quality drawings for manufacturing and assembly.

This position is contingent on ENR-26 award and the salary range is between $120K-$148K.

• Design mechanical equipment, components, and equipment-to-facility interfaces for chemical/energetic material manufacturing systems and unmanned systems hardware.
• Develop 3D models and assemblies in Solid Works and produce 2D drawings/layouts in AutoCAD.
• Create manufacturing‑ and assembly‑ready drawing packages, including GD&T per ASME Y14.5.
• Perform structural and mechanical analysis (FEA) to validate designs for strength, fatigue, and operational loading.
• Manage CAD data and revisions through a PDM system (e.g., Solid Works PDM/Vault).
• Coordinate with chemical and process engineers to align equipment design with process requirements and DoD facility standards.
• Support design reviews, technical interchange meetings, and site visits with government customers at Indian Head, MD.
• Generally consider hazard classification, explosive safety, and facility siting requirements when designing equipment for energetic material applications.
• Provide informal technical mentorship to junior engineers on design practices, drafting standards, and tools.

• Bachelor's degree in Mechanical Engineering.
• 8 years of relevant mechanical design experience.
• Demonstrated proficiency in Solid Works (modeling, assemblies, drawings) and AutoCAD.
• Strong working knowledge of GD&T (ASME Y14.5).
• Experience with FEA/simulation tools for mechanical design validation.
• Experience using a PDM system for CAD data management.
• Ability to produce drawing packages suitable for manufacturing and assembly release.
• U.S. Citizenship required; must be eligible to obtain a security clearance.
• Willingness to travel regularly between Arlington, VA and Indian Head, MD.

• Masters in Mechanical Engineering with 6-8 years of relevant mechanical design experience.
• PhD in Mechanical Engineering with 3-5 years of relevant mechanical design experience.
• Experience designing equipment for chemical processing, energetics, or hazardous material manufacturing environments.
• Familiarity with DoD facility design standards (UFC) and explosive safety requirements.
• Experience supporting unmanned systems (UxS) hardware design.
• Prior experience interfacing directly with government program offices or customers.
