Job description

ATC is looking for an early-career Mechanical Designer to join our Advanced Solutions Group, where we design and deliver innovative sensing systems for space, airborne, and terrestrial applications. This is a great opportunity for a recent graduate or program completer to build real hands‑on experience, work alongside experienced engineers, and grow into a full engineering role. You don't need years of industry experience to apply - we're looking for someone with a solid technical foundation, curiosity, and a willingness to learn. You'll get direct mentorship from senior engineers while contributing to real hardware that is used in the field.

What You'll Do

• Support the design and modeling of mechanical components, assemblies, and enclosures for sensors used in aerospace and defense applications
• Create and update detailed 3D models and drawings under the guidance of senior engineers
• Work alongside Systems, Electrical, RF, and Firmware engineers to support custom electronics systems design
• Help prepare documentation for design reviews, tolerance analyses, and manufacturing drawings
• Assist with mechanical integration, assembly, and testing of hardware in the lab
• Support environmental qualification and verification activities, including hands‑on time with test equipment
• Learn from and collaborate with experienced mentors as you build your engineering skill set
• Participate in team meetings and contribute ideas as you grow into greater ownership of projects

Required Qualifications

• Associate's degree in Mechanical Engineering Technology, Drafting & Design, or a related technical field - OR a technical/vocational high school diploma (e.g., machine technology, engineering technology, or drafting program) with relevant co‑op or hands‑on project experience
• Exposure to 3D CAD tools (such as SolidWorks, Inventor, Creo, or NX) through coursework, co‑op, internship, or personal projects
• Basic familiarity with engineering drawings and dimensioning concepts (GD&T exposure through coursework is a plus, not a requirement)
• Strong attention to detail and a genuine interest in mechanical design and hardware
• Good communication skills and comfort working as part of a team
• Willingness to work hands‑on in a lab or shop environment as needed

Preferred Qualifications

These are a bonus, not a requirement - we're happy to help you build these skills on the job:

• Co‑op, internship, or capstone project experience in aerospace, defense, or manufacturing
• Some exposure to tolerance stack‑ups or manufacturing/assembly drawing standards
• Familiarity with common aerospace materials (aluminum, titanium, composites)
• Experience with hand tools, machine shop equipment, or lab test setups

Growth Opportunities

• Take on increasing ownership of mechanical design tasks and small subsystems
• Receive structured mentorship from senior and principal engineers
• Build skills in analysis, testing, and system‑level design
• Grow into a full Mechanical Engineer role as your experience develops

Eligibility Requirements

Must be a U.S. Citizen.

Why ATC?

At ATC, you'll start your career working on real engineering problems that matter - supporting advanced sensing systems used in demanding aerospace and defense environments. You won't just observe; you'll contribute, ask questions, and learn from engineers who want to see you grow.

We value curiosity, collaboration, and a strong work ethic just as much as a polished resume. If you're a recent graduate, program completer, or early‑career technician ready to launch your engineering career, we'd love to hear from you.
