About the Role

We are seeking a highly-motivated and experienced Mechanical Engineer to join our growing team. In this role, you’ll design precision mechanical and optomechanical systems for telescopes and related equipment. You’ll work with a multidisciplinary team of optical, electrical, and software engineers to deliver observatory-grade systems for ground-based and potential future space-based deployment.

What You'll Bring

  • Design and optimize mechanical and optomechanical components (e.g., telescope tubes, mounts, enclosures, optical supports).
  • Create detailed 3D CAD models, engineering drawings, and bills of materials (BOMs).
  • Conduct FEA simulations for stress, thermal, and vibrational environments.
  • Collaborate with optics and software teams to ensure mechanical compatibility with imaging, tracking, and sensing subsystems.
  • Support the full product lifecycle, from concept design and prototyping to testing and production.
  • Participate in and contribute to design reviews (PDR, CDR, etc.) and internal documentation.
  • Provide engineering support during fabrication, QC, assembly, and system validation.

What You'll Do

  • Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or equivalent.
  • 5+ years in a Mechanical Engineering role in Aerospace, Automotive, or a related industry.
  • Strong proficiency in CAD tools (SolidWorks, NX, or similar).
  • Understanding of FEA (ANSYS, Nastran, etc.), tolerance analysis, and DFM principles.
  • Hands-on experience with fabrication, machining, welding, drilling, and/or mechanical assembly.
  • Effective communicator and collaborator.
  • Demonstrated passion for aerospace or observational technologies.

Preferred Qualifications

  • Grasp of materials, fasteners, coatings, and alignment techniques.
  • Understanding of system engineering workflows, interface control documents, and verification processes.
  • Basic scripting or automation (Python, MATLAB) for design or test workflows.
