Associate Laser Systems Engineer

Infleqtion•Boulder, CO

3d•$90,000 - $110,000

About The Position

Within Infleqtion’s Quantum Computing Product Group, the Hardware Engineering Team is seeking an Associate Laser Systems Engineer for neutral-atom quantum computing hardware. The role involves carrying out well-defined laser assembly, characterization, and control tasks while building practical judgment through laboratory work and design reviews. Dedicated time for technical learning and hands-on training is provided, with regular guidance from experienced engineers. Work is normally performed in an office and laboratory environment around technical equipment, including computers and lasers. Up to 10% travel may be required. The position may require access to information protected under U.S. export control laws and regulations; an employment offer may be conditioned on authorization to receive controlled software or technology without sponsorship for an export license.

Requirements

Bachelor’s degree in optical engineering, physics, electrical engineering, or a related field.
Understanding of laser and optical fundamentals, including beam propagation, polarization, interference, and frequency.
Hands-on practice assembling an optical or electro-optical setup and taking measurements while following laboratory safety procedures.
Practice interpreting detector signals and explaining how gain, noise, and negative feedback affect a measurement or control loop.
Experience analyzing measurements, comparing them with predictions, and explaining differences using calculations, spreadsheets, or scripts.
Experience keeping accurate setup and measurement records, checking work for errors, and flagging unexpected results.
Experience explaining technical work clearly, raising questions or problems early, and incorporating feedback.

Nice To Haves

Project experience with laser characterization, optical modulation, or feedback control.
Experience using Python or comparable tools to collect and analyze laboratory data.
Experience with atomic spectroscopy, optical resonators, or low-noise photodetection.
Coursework, laboratory classes, research, internships, and projects may demonstrate the relevant skills; preferred qualifications are helpful but not required.

Responsibilities

Assemble and align assigned laser paths using reviewed layouts and laser-safety procedures.
Calculate expected power levels and frequency shifts for assigned setups and compare predictions with measurements.
Measure laser power, polarization, beam profiles, and short-term stability against provided acceptance criteria.
Set up detectors, modulation stages, and feedback controls using reviewed procedures; record their response and operating settings.
Work with engineers to isolate alignment, signal, or lock problems, test fixes, and flag issues beyond the assigned scope.
Record setup changes, measurements, and test conditions so others can reproduce the work; submit procedure improvements for review.
Plan assigned tasks, report progress and blockers, and incorporate feedback from design and test reviews.
Use required personal protective equipment properly in accordance with company requirements.
