Mechanical Design Engineer

About Us

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. 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.

About the Role

The Mechanical Design Engineer will be responsible for the full lifecycle of mechanical design, from conceptualization and detailed design to prototyping, testing, and production support. This role requires a strong foundation in mechanical engineering principles, proficiency in CAD software, and a passion for developing robust and reliable systems in a fast-paced environment.

What you’ll do

• 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.

What you’ll need

Required

• 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.

Preferred

• 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.

Benefits

• Competitive salary and comprehensive benefits package.

• Opportunities for professional development and growth.

• Engaging work on impactful projects that contribute to national security.

• A collaborative and innovative work environment.
