Engineering Technician - Level III

Infleqtionis a global quantum technology company solving the world’s most challenging problems. The company harnesses quantum mechanics to build and integrate quantum computers, sensors, and networks. From fundamental physics to leading edge commercial products,Infleqtionenables “quantum everywhere” through our ecosystem of devices and platforms.

Working in our production area, this role willbe responsible for assembling sub-components, sub-system sand completeproductsin

Infleqtion’scommercial Time & Frequency product line.

This role requires good manual dexterity, ability to conduct visual inspections, understanding of mechanical, electrical, and optical engineering equipment, and commitment to follow all safety processes.

The duties and responsibilities outlined below include essential functions of the role. Depending on business needs, this role mayperforma combination of some orall ofthe 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 whilemaintainingquality, 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 work streams; isolate likely root causes and propose practical corrective actions.

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

• Demonstrates advancedproficiencyacross multiple applicable production processes and product areas, with the ability to cross-train intonew processes quickly.

• Train, mentor, andprovidetechnical guidance to Level I/II technicians onbuildmethods, 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

• Associate degree in a technical field and 5+ years of relevant hands‑on experience in precision assembly, optics, lasers, vacuum systems, photonics, semiconductor, aerospace, medical device, or similar high-reliability hardware environment; or equivalent combination of education and experience.

• Demonstrated experience with at least three of the following: precision optical assembly, fiber handling, laser systems, electro‑mechanical assembly, RF assembly, precision metrology, delicate‑component handling, cable/harness assembly, alignment, bonding, adhesive processes, or cleanroom production.

• Ability to read and interpret mechanical drawings, GD&T, assembly drawings, BOMs, travelers, schematics, and inspection plans.

• Experience using structured build documentation, nonconformance processes, change control, and production quality systems.

• Comfort and…
