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.
