JOB RESPONSIBILITIES The duties and responsibilities outlined below include essential functions of the role. Depending on business needs, this role may perform a combination of some or all of the following duties. Duties, responsibilities, and activities may change, or new ones may be assigned at any time with or without notice.

• Independently perform complex, multi-step assembly processes for optical, mechanical, and electrical assemblies using work instructions, drawings, solid models, schematics, and engineering judgment.

• Own assigned builds from kit readiness through final inspection, test support, documentation, nonconformance resolution, and handoff to the next production or engineering stage.

• Execute new, complex, or low-volume builds where documentation may be incomplete, escalating gaps while maintaining quality, safety, and configuration control.

• Partner with engineering to translate drawings, prototypes, and informal process knowledge into repeatable build methods, fixtures, work instructions, and inspection criteria.

• Perform necessary maintenance and housekeeping activities to ensure a clean and safe work area

• Act as a quality gate for assigned builds, ensuring workmanship, cleanliness, documentation, and inspection results meet product and customer expectations before handoff.

• Independently troubleshoot assembly, inspection, test, tooling, and process issues across optical, mechanical, and electrical workstreams; isolate likely root causes and propose practical corrective actions.

• Support root-cause analysis, corrective actions, and verification of process fixes.

• Demonstrates advanced proficiency across multiple applicable production processes and product areas, with the ability to cross-train into new processes quickly.

• Train, mentor, and provide technical guidance to Level I/II technicians on build methods, inspection standards, workmanship expectations, cleanroom behavior, and safe equipment use.

• Provide feedback on work instructions, training materials, fixtures, and inspection methods to improve repeatability and reduce technician-to-technician variation.

• Other duties or projects as assigned
