Opto-Mechanical Engineer

Opto-Mechanical Engineer

TTM Technologies, Inc. is a leading global manufacturer of technology products, including mission systems, radio frequency ("RF") components, RF microwave/microelectronic assemblies, and technologically advanced printed circuit boards ("PCB"s). TTM stands for time-to-market, representing how TTM's time-critical, one-stop design, engineering and manufacturing services enable customers to reduce the time required to develop new products and bring them to market.

We are seeking an Opto-Mechanical Engineer with rigorous optical and mechanical engineering fundamentals and hands-on experience in the precision assembly, alignment, and characterization of discreet optical components including micro-optics at module scale. The right candidate is comfortable developing new-to-world opt-mechanical manufacturing capabilities and technologies for high volume manufacturing, analyzing and optimizing optical performance, and collaborating across domains with internal engineering and with external vendors.

Key Responsibilities:

• Module-Scale Fixture Design:
  Design precision assembly fixtures and alignment tooling for millimeter - scale optical components-guide pin registration fixtures, fiducial-alignment systems, precision reference datums, retention assemblies, adhesive selection and adhesive dispensing fixtures. Apply kinematic constraint design principles.
• Tolerance & Error Budgets:
  Perform worst case and RSS tolerance stack-up analysis - quantifying contributions from mechanical, optical and environmental causes.
• Assembly Process Development:
  Develop and optimize passive alignment assembly processes for opto-mechanical sub-assemblies. Define adhesive cure parameters (dose, shrinkage control), press-fit forces, and retention preloads. Characterize process capacity (Cpk) for critical alignment dimensions.
• Vendor
  
  Collaboration:
  
  Collaborate with precision optical component vendors on design-for-manufacturability, first article inspection, and ongoing process control. Review vendor dimensional and optical measurement data against specifications.
• Alignment Characterization:
  Characterize lateral and angular misalignment distributions in assembled opto-mechanical sub-assemblies using far-field beam profiling, interferometry, or precision displacement measurement. Validate experimental results against analytical loss models.
• Component Incoming Inspection:
  Develop incoming inspection protocols for precision optical components - mirror angle, reference surface geometry, guide pin hole position and diameter, lens surface form, and bore position accuracy. Define sampling plans and accept/reject criteria appropriate to downstream optical performance requirements.
• Provide technical accuracy review of optical and mechanical specifications in engineering documentation, including patent-related technical disclosures.
• Collaborate with process engineering on alignment station design, throughput modelling, and assembly process cost analysis.
• Support prototype and proof of concept build activities - component procurement, sub-assembly, and optical performance characterization.
• Author engineering specifications, assembly SOP's, test procedures, and component qualification reports.
• Assisting with optical simulation testing.

Qualifications:

Education & Experience:

• B.S. in Optical Engineering, Mechanical Engineering, Applied Physics, or a closely related discipline with substantial optics and photonics coursework.
• 3–10 years of hands-on opto-mechanical engineering experience in precision manufacturing, photonics product development, or optical instrumentation.
• Demonstrated experience in the assembly and alignment of systems similar to; discrete optical components at module scale — fiber optic transceivers, free-space optical modules, precision optical instruments, or comparable millimeter-scale opto-mechanical assemblies.
  
  Note:
  
  this is an emerging application area; directly analogous module-scale assembly experience is valued over any single industry background.
• Experience with precision optical component vendor interface — specification writing, first-article review, and qualification — preferred.
• Experience with adhesive…
