Job Description

The Lead Mechanical Engineer is responsible for directing the design, analysis, and integration of high-performance opto-mechanical systems, such as telescopes, beam directors, and related instruments and subsystems. The role spans the development of precision structures, mechanisms, and optical support assemblies for use on platforms ranging from terrestrial to spaceborne. Responsibilities include leading mechanical design teams in CAD modeling, performing or overseeing structural and thermal analyses, requirements tracking, and drawing release, while ensuring compliance with system-level performance and functional requirements. The role requires close coordination with optical, controls, electrical, and systems engineering disciplines, oversight of vendors and fabrication, and support for tooling development, assembly, integration and test. The Lead Mechanical Engineer also contributes to program planning by supporting proposals, cost and schedule estimating, and risk management.

Primary Duties & Responsibilities

• Lead the design of large telescope structures, mounts and optical support assemblies
• Perform and / or oversee FEA for gravity sag, thermal distortion, thermal management, wind loading, and dynamic response
• Participate in the characterization of system and component-level optical performance
• Develop mirror support mounts, metering structures, and precision, multi-degree-of-freedom positioning actuators for alignment maintenance
• Coordinate across disciplines (optical, controls, electrical, systems) to ensure functional and performance requirement compliance
• Manage CAD modeling, detailed drawing generation, and tolerance budgeting
• Integrate mechanical designs with subsystems such as drives, bearings, enclosures, and thermal management systems
• Define technical requirements, support procurement, and oversee vendor fabrication / testing
• Lead risk reduction activities such as breadboards, subscale prototypes, and structural tests
• Support assembly, integration, and test with tooling design and review of work instructions
• Manage as-built documentation through a formal configuration management process, including troubleshooting and dispositioning non-conforming material
• Present design status, risk assessments, and compliance evidence at major reviews (PDR, CDR)
• Contribute to proposals, cost and schedule estimating, and program planning
• Mentor junior engineers and provide technical guidance to the mechanical design team
