Engineering Technician - Level III

Infleqtion is 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, Infleqtion enables “quantum everywhere” through our ecosystem of devices and platforms. POSITION SUMMARY Working in our production area, this role will be responsible for assembling sub-components, sub-systems and complete products in Infleqtion’s commercial 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. 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 Requirements QUALIFICATIONS: EDUCATION AND EXPERIENCE 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 familiarity with standard clean room practices and working in clean rooms Familiarity with optical surface quality specifications: MIL-PRF-13830B and ISO 10110-7 Experience with RF assembly and Optical handling experience is desired Ability to inspect parts against technical drawings, including those with GD&T tolerancing Good dexterity to assemble small components into sub-assemblies Proficient in MS Office WE HIGHLY VALUE: Exceptional craftsmanship, attention to detail, and pride in producing clean, precise, reliable hardware. Strong technical judgment; knows when to proceed, when to stop, when to escalate, and how to protect product quality. Ability to take a high-level goal, identify missing information, gather resources, and drive work to completion with limited supervision. Broad hands-on curiosity and the ability to learn new products, tools, and processes quickly. Strong problem-solving skills, including the ability to use data, inspection results, build history, and hands-on observation to diagnose issues. Clear verbal and written communication with both technical and non-technical teammates. Ownership mindset, urgency, and willingness to improve the pro…
