Opto-mechanical Engineer (Quantum Computing)

ColdQuanta • Boulder, CO • 1h ago

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 seeks an Opto-mechanical Engineer as a designer responsible for the realization of precision opto-mechanical subsystems that underpin scalable, high-performance quantum hardware.

The successful candidate will support opto-mechanical, module-level designs working closely with physicists and cross-disciplinary engineering teams in a laboratory focused environment.

JOB RESPONSIBILITIES

Typically, you will be entrusted with:

Working on opto-mechanical subsystems and supporting identification and escalation of technical risks, trade-offs and constraints.

Designing components for opto-mechanical integration of precision components and assemblies supporting lasers, optics, vacuum-integrated components, state-of-the-art sensors, high-speed photodetectors, DMDs, SLMs, AODs, and EOMs.

Collaborating with physicists and optical, mechanical, electrical, software, and systems engineers through the hardware development lifecycle, from early research demonstrations through integrated, scalable systems.

Adhering to design-for-manufacturing and design-for-assembly considerations early in the product lifecycle and performing hands-on root-cause investigations, corrective actions, and laboratory subsystem's assembly.

Using high-fidelity opto-mechanical simulations and executing on experimental strategies to characterize optical stability, drift, noise sources, and scaling limits, ranging from back-of-the-envelope calculations to detailed finite element analysis (FEA) encompassing tolerance stack-ups, thermal behavior, structural stiffness, and vibration sensitivity.

Supporting the transition of opto-mechanical subsystems from research-grade configurations to repeatable, maintainable, and scalable hardware suitable for increased atom counts.

Advancing current best practices for optical design workflows, laboratory procedures, documentation, and version control.

Requirements

Bachelor's degree in optical engineering, mechanical engineering, physics, or a related field.

Hands-on experience with optical alignment and laboratory work.

Familiarity with SolidWorks for component design.

Strong experimental rigor and documentation habits.

Desire to learn basic Zemax (OpticsStudio).

WE HIGHLY VALUE:

Curiosity and enthusiasm for opto-mechanical setups and lasers.

A hands-on, detail-oriented mindset with a strong sense of ownership and technical accountability.

Positive, collaborative working style and enthusiasm.
