Laser Systems Engineer

At Infleqtion we solve the world’s most challenging problems using cutting-edge quantum technology. Our mission is to commercialize atom-based quantum products that provide orders of magnitude improvements in sensing and computing applications. We are proud to work tirelessly to create and lead the quantum ecosystem towards meaningful advancements today and set the technology roadmap for tomorrow.

POSITION SUMMARY

Within Infleqtion’s Quantum Computing Product Group, the Hardware Engineering Team is seeking an Associate Laser Systems Engineer for neutral-atom quantum computing hardware. You will carry out well-defined laser assembly, characterization and control tasks, building practical judgment through laboratory work and design reviews. You’ll have dedicated time for technical learning and hands-on training, supported by regular guidance from experienced engineers.

JOB RESPONSIBILITIES Typically, you will be entrusted with:

 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.

Requirements

WE HOPE YOU HAVE:

 Bachelor’s degree in optical engineering, physics, electrical engineering or a related field. Prior industry experience is not required.

 Understanding of laser and optical fundamentals, with practice explaining 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.

WE HIGHLY VALUE:

 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 can demonstrate these skills. Preferred qualifications are helpful, not required.
