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 process development - preferred.
