Infleqtion•Louisville, CO

12d•$120,000 - $160,000•Onsite

About The Position

Infleqtion is a global quantum technology company solving some of the world’s most challenging problems by building and integrating quantum computers, sensors, and networks. The QGG Pathfinder program brings together atomic physics, aerospace hardware, electronics, software, supply chain, and mission assurance to mature a flight-relevant quantum gravity gradiometer payload. Infleqtion is seeking a Mechanical Engineer II to support QGG mechanical design, drawings, tooling, fixtures, and low-complexity part ownership. This role is ideal for a hands-on engineer who enjoys converting technical direction into clean CAD models, released drawings, buildable parts, and practical tooling that helps a complex aerospace quantum payload move from design into integration.

Requirements

Bachelor’s degree in mechanical engineering or a related technical field.
2+ years of mechanical design experience, including CAD modeling and production-quality mechanical drawings.
Experience with SolidWorks or an equivalent CAD tool.
Working knowledge of GD&T, engineering drawings, tolerance basics, material selection, and manufacturing processes.
Ability to design simple tooling, fixtures, brackets, adapters, and low-complexity mechanical parts with minimal rework.
Good collaboration and communication skills; able to take technical direction and close actions reliably.
Comfortable supporting hands-on hardware work in laboratory, shop, or integration environments.

Nice To Haves

Experience with PDM/PLM release processes and ECOs.
Experience with aerospace, optical, vacuum, laser, or precision electromechanical hardware.
Experience designing assembly/alignment tooling, inspection fixtures, environmental-test fixtures, or handling hardware.
Basic experience with FEA, thermal/structural hand calculations, or tolerance analysis.

Responsibilities

Create and revise CAD models and mechanical drawings for QGG parts, tooling, fixtures, brackets, covers, adapters, and low-complexity assemblies.
Support opto-mechanical, structural, thermal/mechanical, APPSH build, and AI&T tooling needs under direction from senior engineers and IPT leads.
Develop drawing packages with appropriate dimensions, tolerances, materials, finishes, notes, and inspection features.
Apply GD&T and tolerance stack-up thinking appropriate to the part function and manufacturing method.
Design for manufacturability, assembly, inspection, cleanliness, handling, and integration constraints.
Work with vendors and internal teams to resolve drawing questions, fabrication issues, and fit/function concerns.
Support design reviews, peer checks, drawing release, ECOs, and configuration updates.
Create simple analysis, hand calculations, or engineering rationale to support designs.
Provide hands-on build, fit-check, and troubleshooting support in lab, shop, or AI&T environments.
Document design decisions and open issues clearly so higher-level owners can make fast decisions.
