CACI is currently looking for a mid-level Mechanical Engineer to join our team supporting Office of Naval Research (ONR) for the Department of Defense. Join our passionate team of industry-leading individuals on a program that leverages the best practices in Systems Engineering and Rapid Prototyping to integrate and deliver state of the art capability in support of our nation's warfighters. As a member of the CACI Team, you will support the men and women charged with safeguarding the American people and enhancing the Nation's safety, security, and prosperity.

Our warfighters are on the front lines, every day, protecting our national security from the increasingly sophisticated and complex threats of our adversaries. CACI programs thrive in a culture of innovation and are constantly seeking individuals who can bring creative ideas to solve complex problems, both technical and procedural at the team and portfolio levels. The ability to be adaptable and to work constructively with a technically diverse and geographically separated team is crucial.

Responsibilities:
Develop 3D CAD models using industry-standard tools (e.g., Solid Works, Creo) optimized for rapid manufacturing and attainable cost targets. Design thermal management solutions and ruggedized housings for delicate electronics and power systems. Integrate custom mechanical hardware with COTS/GOTS payloads for ground and aerial robotics platforms. Execute the in-house prototyping workflow from design to physical fabrication. Perform hands-on manufacturing, including 3D printing, CNC machining, and manual fabrication, alongside electromechanical assembly to build functional prototypes.

Ensure that a level 2 Technical Data Package (TDP) is prepared and delivered for assigned projects that reach the prototype or low-rate production stages of development, assist in the development of the TDP and create/maintain basic briefs for various prototype devices. Prepare and deliver Test Plans for structural, environmental, and mechanical performance testing of prototypes. Validate mechanical integrity and environmental resilience using standard testing apparatus.

Conduct root cause failure analysis on physical components (e.g., wear, stress fractures, thermal failure) to inform design improvements. Travel to various Continental United States (CONUS) locations to support live test events and operational evaluations. Provide essential on-site technical support, real-time troubleshooting, and data collection for prototype systems under test. Interact with and coordinate prototype and low-rate production with external parties tasked with producing units for assigned projects.

Provide routine status updates via the Monthly Status Report. The contractor shall communicate urgent matters involving production issues to the government in a timely manner via phone, email, or other normal communication methods Development maintenance schedules and procedures for systems, identify and resolve issues. Purchase material for the government as needed to support prototype and low-rate production for assigned projects.

The value of purchases will be within contract ceiling and defined in specific task orders/instructions. Offer leadership and technical project management support to engineering teams and projects, ensuring timely and successful delivery of key systems. Collaborate with electrical engineers, software developers, and other subject matter experts/stakeholders to integrate mechanical systems into larger projects. The selected individual must be a self-starter, capable of working with minimal oversight and have excellent written and verbal communication skills.
