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 As part of a collaborative engineering team, you will:
  • 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 This role is designed as a launchpad. As you build experience, you'll have opportunities to:
  • 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.
