Job summary

Infleqtion is seeking a Senior Opto-Mechanical Engineer to lead precision opto-mechanical subsystem design foundational to scalable quantum hardware. You will translate experimental requirements into robust optical hardware, guiding engineers and collaborating with physicists across disciplines to enable future scaling paths.

The role emphasizes hands-on lab work, model-based analysis, and design-for-manufacturing practices to ensure reliable, repeatable performance in next-generation

Qualifications

• Bachelor's degree in optical/ mechanical engineering, physics, or related field with at least 5 years of experience.
• Extensive hands-on experience designing, modeling, and validating laser-based opto-mechanical systems with a strong lab track record.

Responsibilities

• Own opto-mechanical subsystems within an established hardware architecture, identifying risks and scalability constraints.
• Design and integrate precision components for lasers, optics, vacuum components, sensors, DMDs, SLMs, EOMs and PICs.
• Explore emerging optical technologies and implement them in next-gen neutral-atom quantum computing architectures.
• Generate stability, tolerance, and error budgets for opto-mechanical systems across environments.
• Collaborate with physicists and engineers across disciplines to support R&D through scalable hardware.
• Advance design-for-manufacturing and design-for-assembly early in the lifecycle using data-driven methods and root-cause analysis.
• Use high-fidelity simulations and experiments to characterize stability, drift, noise, and scaling limits.
• Provide technical leadership and mentorship through design reviews and hands-on coaching.
• Support transition from research configurations to repeatable, scalable hardware for more atom counts.
• Improve optical design workflows, lab procedures, documentation, and version control.
