Core Responsibilities

Primary Functions

Precisely assemble, align, and integrate lenses, mirrors, prisms, fiber ferrules, optomechanical mounts and subassemblies according to engineering drawings and process documentation, achieving specified optical tolerances and repeatable performance.
Perform interferometric measurements (e.g., Zygo, Twyman-Green) to verify surface figure, wavefront error, and transmitted wavefront, and record results in the quality management system.
Calibrate and maintain laser sources, power meters, spectrometers, beam profilers and other optical test equipment to ensure traceability and measurement accuracy within defined uncertainty budgets.
Execute optical alignment using microscopes, translation stages, kinematic mounts, beam splitters and active alignment tools to optimize coupling efficiency, M2, beam waist position and pointing stability.
Build and test fiber-optic assemblies including fiber cleaving, splicing (fusion and mechanical), connectorization (FC/PC, LC, ST), polishing and insertion loss testing using OTDRs and power meters.
Develop, follow and refine standardized test procedures and work instructions (SOPs) for acceptance, environmental, and final functional tests, ensuring consistent product quality and manufacturability.
Troubleshoot optical and optoelectronic systems by isolating optical, mechanical and electronic root causes; recommend corrective actions and implement fixes under engineering guidance.
Measure optical coatings and spectral response using spectrometers and reflectometers to confirm coating performance, bandpass, and reflectance/transmittance specifications.
Perform optical characterization of assemblies (e.g., modulation transfer function, spot size, signal-to-noise ratio) and analyze data to verify compliance with design requirements.
Use computer-aided design prints, assembly drawings and BOMs to identify components, fasteners and adhesives; perform optomechanical assembly with torque and cleanliness controls.
Record and manage test data, produce detailed inspection and test reports, enter results into LIMS / QMS, and support traceability for customer and regulatory audits.
Conduct environmental, vibration and thermal tests on optical subassemblies, monitor performance under stress, and document any drift or degradation in optical alignment or throughput.
Clean, inspect and handle optical elements using approved solvents, lint-free wipes and particle control methods to prevent contamination and surface damage in accordance with cleanroom protocols.
Apply adhesives and potting compounds precisely for optical bonding and sealing, and cure materials following safety and process specifications to avoid induced stress and index mismatch.
Collaborate with opto-mechanical and electrical engineers to translate prototype designs into robust, manufacturable products, recommending design-for-manufacture and testability improvements.
Perform incoming inspection and sampling of optical components from vendors, verifying dimensional, surface quality and coating specifications and escalating nonconformances.
Set up automated test stations, integrate sensors and data acquisition (DAQ) interfaces, and run batch tests to support production throughput and statistical process control.
Participate in root-cause analysis (RCA), CAPA, FMEA and continuous improvement projects to reduce scrap, lower rework rates and increase first-pass yield in optical manufacturing.
Train manufacturing and test personnel on safe handling of lasers and hazardous optical materials, proper use of measurement equipment and adherence to safety and cleanroom rules.
Maintain inventory of critical optical parts, tools and calibration standards and place requisitions based on production forecasts and vendor lead times to minimize downtime.

Secondary Functions

Support prototype builds and small-batch product introductions, providing feedback on assembly time, tooling needs and test coverage.
Assist engineering teams with lab characterization campaigns, including custom fixture fabrication and ad-hoc measurement setups.
Contribute to continuous improvement initiatives by proposing process changes, tooling improvements and test automation to improve throughput and reduce variation.
Help maintain lab and cleanroom facilities, ensure equipment calibration schedules are met, and perform preventive maintenance on optical benches and alignment stages.
Support customer returns and field failure investigations by reproducing failure modes, documenting evidence, and providing actionable recommendations.
Participate in cross-functional design reviews to ensure manufacturability, serviceability and compliance with optical performance targets.
Provide hands-on support during installation, commissioning and on-site acceptance testing when required.
Update and refine job travelers, assembly instructions and training materials to reflect process changes and best practices.
Monitor and implement EHS (Environmental, Health & Safety) and laser safety requirements, including signage, eyewear policy and hazard controls.
Collaborate with suppliers to improve component quality, clarify drawing requirements, and expedite corrective actions for nonconforming optical parts.
