Why Castelion, Why Now

Castelion is moving incredibly fast to develop and deliver advanced defense systems at a time when execution matters more than ever. We believe focus, ownership, and excellence are decisive advantages - and we're building a world-class team to turn bold ideas into real capability.

This is a rare opportunity to join at an early stage, where you'll have significant ownership, collaborate with exceptional teammates, and make a direct, measurable impact on our mission and the future of the company - regardless of your function.

We are seeking an experienced Staff Toolmaker / Laser Tracker Operator to run laser tracking and precision tooling operations in support of large-scale aerospace structures. This role combines hands-on measurement expertise with process ownership, cross-functional leadership, responsibility for inspection strategy, scheduling, and quality outcomes from prototype through flight hardware.

The ideal candidate has deep, hands-on mastery of laser trackers and Verisurf (or equivalent model-based software), a proven track record leading complex builds, and the ability to translate measurement data into clear direction for fabrication, machining, assembly, and engineering teams.

• Run specific jobs related to laser tracking, including Verisurf (or equivalent) license management, tracker scheduling, remote site support, and coordination across facilities.
• Collect geometric data using laser trackers (Leica, Faro, API, and similar) through model-based software; establish, apply, and install reference systems both on and off the part.
• Use advanced GD&T knowledge to interpret blueprints at all assembly levels and define appropriate datum and alignment strategies.
• Analyze collected data and provide clear technical direction for remaining tooling, welding, machining, and assembly operations.
• Integrate process monitoring with fabrication processes; account for free states, temperature swings, weld shrinkage, and other environmental effects on large structures.
• Lead complex build efforts from blueprint through final installation, including precision drilling/dowelling, epoxy pours, rigging, and large-scale assembly workflows.
• Communicate effectively with fabricators, machinists, assemblers, engineers, and other stakeholders; influence cross-functional decisions and resolve measurement-related issues.
• Drive continuous improvement by redesigning tooling and inspection strategies to reduce rework and improve first-time quality.
• Ensure all operations are performed safely and meet aerospace quality standards; maintain an orderly, high-utility work environment.
• Travel between sites as needed to support builds, inspections, and remote operations.

• 10+ years of experience in toolmaking, laser tracking, or aerospace manufacturing.
• Advanced proficiency in Verisurf inspection software (or equivalent), including model manipulation, feature reporting, alignment strategies, and reference system establishment.
• Deep hands-on experience with Leica, Faro, and/or API laser trackers, including supporting hardware (arms, probes, targets, etc.).
• Strong GD&T knowledge and ability to apply it to complex aerospace structures.
• Proven track record leading complex build efforts from blueprint to final installation.
• Experience with rigging, epoxy pours, precision drilling/dowelling, and large-scale assembly workflows.
• Demonstrated ability to lead technical work and influence cross-functional stakeholders.
• Willingness to travel between sites as needed.
• High school diploma or equivalency; relevant technical experience required in lieu of higher…
