Senior Mechanical Designer

Accelint is a mission-driven technology company focused on strengthening national security and supporting critical industries. We build the technologies that help operators and organizations see what’s happening, make faster and better decisions, take action with confidence, and stay ready for what comes next. Our work includes advanced sensors, autonomous systems, mission command and control software, AI-enabled training and simulation, and tools that improve logistics, maintenance, and overall readiness.  

For nearly 30 years we have supported military and civilian agencies across the Department of Defense, U.S. allies and partners, and essential industries. When you join Accelint, your work directly contributes to protecting national security and strengthening the systems our society depends on.  

Accelint is seeking a Senior Mechanical Designer to support the development, integration, and sustainment of advanced electromechanical defense systems, autonomous platforms, and sensor payloads. This position is intentionally structured around a highly experienced hands-on design professional with deep expertise in top-level assembly ownership, CAD standards, electromechanical integration, production drawing release, and design-process automation.

The successful candidate will serve as the organization’s mechanical design authority for complex assemblies, owning the mechanical product definition from concept layout through released drawing packages and production support.

This role will work closely with mechanical, electrical, software, systems, and manufacturing teams to ensure rapid and disciplined execution of development efforts across USV platforms, payload systems, radar subsystems, and supporting hardware.

In addition to design execution, this individual will drive CAD best practices, PDM/PLM workflow governance, template control, and engineering automation initiatives to improve engineering cycle time and quality.

Duties & Responsibilities 

• Own top-level mechanical and electromechanical assemblies across multiple defense programs
• Develop detailed 3D CAD models, production drawings, and interface-controlled assemblies
• Create and maintain engineering drawing packages, BOMs, revision-controlled releases, and ECNs/ECRs
• Lead mechanical subsystem integration to ensure all interfaces across structural, electrical, and payload systems align correctly
• Apply GD&T and manufacturing-ready tolerancing to released drawings
• Establish and maintain CAD standards, templates, part libraries, and drawing conventions
• Administer and improve PDM / PLM vault workflows, revision control, and release processes
• Develop SolidWorks macros and automation tools to reduce repetitive design tasks and improve engineering efficiency
• Support prototype fabrication, design validation, integration, and production transition
• Collaborate closely with systems, electrical, firmware, and manufacturing teams
• Mentor junior engineers and designers on modeling best practices and design discipline
• Support proposal and capture efforts with concept layouts, design studies, and ROM technical estimates
• Support DFM / DFP initiatives to enable scalable production and repeatable builds

Required Qualifications 

• U.S. Citizenship required
• Ability to maintain or obtain a U.S. Security Clearance
• 15+ years of progressive mechanical design experience in defense, aerospace, industrial, or electromechanical product development
• Expert proficiency in SolidWorks
• Demonstrated experience owning top-level assemblies and subsystem interfaces
• Strong background in electromechanical chassis and system integration
• Advanced experience with PDM / PLM administration
• Strong proficiency in BOM creation, change notices, drawing release, and revision control
• Experience developing CAD templates, design standards, and department workflows
• Expertise in GD&T and production drawing best practices
• Experience building engineering automation macros / API tools
• Strong cross-functional collaboration skills
• Familiarity with Creo / Pro-E preferred
• Experience with additive manufacturing and 3D printing preferr
