Mechanical Design Engineer

About the role

ZeroMark builds AI-driven counter-drone systems that actually work in combat. No PowerPoints. No hype. Just field-proven technology that saves lives. We've doubled year-over-year for two straight years, winning contracts that prove what we've always known: real innovation happens in the dirt, not in conference rooms. Our systems transform standard weapons into AI-powered platforms that detect, track, and neutralize drone threats-because a $200 drone shouldn't require a million-dollar countermeasure. Here's what makes us different: ZeroMark operators don't build from behind screens. You'll validate tech from Blackhawk helicopters, train alongside Tier-1 units (who happen to be our coworkers), and test at legendary ranges from White Sands to the cliffs of Hawaii. When we say field-tested, we mean you'll shoot it, fly with it, and push it to failure. We don't tweet about changing the world-we're too busy actually doing it. Watch us in action here . Dark humor required, thick skin recommended. If you want to make an actual impact-and have some unforgettable Tuesday afternoons along the way-let's talk. We're all about delivering practical, field-tested tech, not just theories.

Responsibilities

• Design & Development:
• Lead the mechanical design of complex defense systems and components, ensuring performance, reliability, and manufacturability.
• Create detailed 3D models, assemblies, and 2D engineering drawings using CAD software.
• Perform engineering calculations, simulations (FEA, CFD), and analyses to validate designs.
• Select appropriate materials, manufacturing processes, and components for designs.
• Prototyping & Testing:
• Oversee the fabrication and assembly of prototypes.
• Develop and execute test plans to validate mechanical designs against performance requirements.
• Analyze test data and implement design modifications as needed.
• Collaboration & Communication:
• Work closely with cross-functional teams, including electrical engineers, software engineers, project managers, and manufacturing personnel.
• Participate in design reviews, providing technical expertise and constructive feedback.
• Document design decisions, specifications, and test results thoroughly.
• Continuous Improvement:
• Stay current with industry trends, emerging technologies, and best practices in mechanical engineering.
• Identify opportunities for design optimization, cost reduction, and process improvements.

Requirements

• Bachelor's degree in Mechanical Engineering or a related field.
• 3-5 years of experience in mechanical design, preferably in the defense, aerospace, or a highly regulated industry.
• Proficiency in 3D CAD software (e.g., SolidWorks, Creo, CATIA).
• Strong understanding of mechanical engineering principles, including statics, dynamics, kinematics, thermodynamics, and material science.
• Experience with geometric dimensioning and tolerancing (GD&T).
• Ability to obtain and maintain a security clearance.
• Bonus Points
• Master's degree in Mechanical Engineering.
• Experience with FEA and CFD software.
• Knowledge of various manufacturing processes (e.g., machining, additive manufacturing, injection molding).
• Familiarity with defense industry standards and regulations.
• Experience with product lifecycle management (PLM) software.
