Lead Facilities Technician

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 a highly proactive, hands-on technician to support the daily operation, maintenance, and readiness of Castelion’s Midland, Texas site. This role combines hands‑on facilities maintenance with day‑to‑day site coordination and is best suited for someone who is comfortable working with tools, troubleshooting basic building issues, supporting contractors, and jumping in wherever needed to keep the site operational.

The Facilities Technician will support general building maintenance across electrical, plumbing, HVAC, mechanical, and facility systems while also owning recurring operational needs such as vendor coordination, site services, supplies, and employee lunch coordination. This is not a primarily administrative or office management position. The successful candidate will spend a significant portion of their time in the field, walking the site, identifying issues, performing basic repairs and maintenance, supporting vendors and technicians, and assisting the Facilities Manager with site projects.

This is a highly dynamic role where no two days will look exactly the same. The ideal candidate is mechanically inclined, resourceful, organized, and comfortable solving problems independently. They should know when an issue can be safely handled directly and when it needs to be escalated to a licensed trade or specialized contractor.

This is a full‑time, on‑site position requiring the ability to work indoors and outdoors in varying weather conditions and flexibility to support changing site priorities and occasional needs outside of standard business hours.
