Lead Mechanical Engineer bei Coherent Corp.

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. This 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

Education & Experience

• Typically requires a bachelor’s degree in mechanical engineering.  An understanding of precision mechanism design and/or opto-mechanical design principles, as well as hands-on hardware assembly, integration, and testing are essential.
• Minimum 7 years of related experience in a professional role with a bachelor’s degree in Optical Sciences or related discipline; or minimum of 5 years of experience with a master’s degree, or 3 years of experience with a doctorate in a relevant field.

Skills

• Strong foundation in structural/mechanical engineering, with emphasis on precision opto-mechanical systems for operation in harsh or challenging environments
• Expertise in CAD (SolidWorks preferred) and/or advanced FEA (NX Nastran or SimCenter are preferred)
• Experience with thermal, structural, and dynamic analysis of opto-mechanical systems
• Familiarity with opto-mechanical interfaces and tolerancing (GD&T) for precision optical systems
• Knowledge of materials selection (steel, aluminum, composites, ceramics) and processing for large precision structures
• Experience designing optical mounts (for reflective or refractive systems) for operation in harsh environments is preferred
• Experience integrating, aligning and testing of optical systems is a plus
• Excellent interpersonal and communication skills; demonstrated ability to achieve results independently or working on a team; strong organizational skills and attention to details required
• Experience with Configuration Management of engineering (as-designed) documentation
• Experience with vendor engagement, fabrication processes, and large component manufacturing
• Solid understanding of design for assembly and integration in complex opto-mechanical devices including alignment planning
• Good analytical and problem-solving skills; familiar with analytical tools used for problem solving and process development
• Strong problem-solving, risk assessment, and trade-study skills
• Excellent communication skills for technical reviews, documentation, and cross-discipline coordination
• Leadership ability to direct design teams and mentor less experienced engineers

Working Conditions

• Job operates in a professional office environment
• Routinely uses standard office equipment such as computers, phones, photocopiers, filing cabinets and fax machines
• Work in a cubicle office

Physical Requirements

• Walk. Occasionally move about inside the office to access file cabinets, office machinery, etc.
• Talking. Expressing or exchanging ideas by means of the spoken word. Those activities in which they must convey detailed or important spoken instructions to other employees accurately, loudly, or quickly.
• Hearing. Perceiving the nature of sounds at normal speaking levels with or without correction. Ability to receive detailed information through oral communication, and to make the discriminations in sound.
• Use hands/fingers to type/handle.  Operating a computer and other office productivity machinery, such as a calculator, copy machine, and computer printer.
• Sedentary Work. Sedentary work involves sitting most of the time. Jobs are sedentary if walking and standing are required only occasionally and all other sedentary criteria are met.
