Facilities Coordinator

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 and technical excellence are decisive advantages - and we are building a team that can deliver real capability, not just concepts.

This is a rare opportunity to join at an early stage, where your work will directly shape critical systems, influence major technical decisions, and have immediate, real-world impact.

Facilities Coordinator – Midland, TX

We are seeking a highly proactive, hands-on Facilities Coordinator to support the daily operations of Castelion's Midland, Texas site. This role is responsible for ensuring the day-to-day needs of the site are handled efficiently and consistently, including employee lunch coordination, snack and beverage programs, janitorial services, recurring site services, vendor coordination, and general facilities support.

This is a highly dynamic role where no two days will look exactly the same. In addition to owning recurring site services, the Facilities Coordinator will work directly with the Facilities Manager and provide support across a wide range of facilities needs and projects as the site continues to grow and evolve.

Success in this role requires someone who is extremely organized, resourceful, flexible, and willing to jump in wherever needed. The ideal candidate has a strong service mindset but is equally comfortable working in an industrial environment, coordinating contractors, moving supplies, solving unexpected problems, or helping execute a facilities project. This person should naturally see what needs to get done and take ownership of getting it across the finish line.

This is a full-time, on-site position requiring flexibility to support changing site priorities and occasional needs outside of standard business hours.

Responsibilities

• Own daily lunch coordination for Castelion employees across the Midland site, including ordering, delivery coordination, setup, and resolution of day-to-day issues
• Manage snack, beverage, kitchen, and general site supply programs across Midland properties, ensuring spaces remain consistently stocked, organized, and operational
• Coordinate recurring site services and vendors, including janitorial, waste services, pest control, water service, landscaping, portable restrooms, and other operational services as needed
• Conduct regular site walkthroughs to identify cleanliness, organization, supply, maintenance, and general site-readiness needs and drive identified issues to resolution
• Assist the Facilities Manager across a wide range of operational needs, facilities projects, and changing site priorities
• Submit, track, and follow up on facilities requests and work orders to ensure issues are resolved in a timely manner
• Partner with EHS, Security, Operations, and other site teams to coordinate facilities activities and maintain a safe and operationally ready environment
• Support site events, employee activities, visitor needs, and other operational requirements as they arise
• Identify opportunities to improve site services, organization, employee experience, and overall facilities operations
• Take on additional site and facilities responsibilities as needed, with a willingness to step outside of routine responsibilities to help the team execute

Basic Qualifications

• 2+ years of experience in facilities coordination, workplace operations, office management, hospitality, site operations, or a related field
• Strong organizational and time management skills with the ability to manage multiple priorities simultaneously
• Demonstrated ability to operate effectively in a fast-paced environment where priorities and responsibilities can change quickly
• Strong ownership mentality with the ability to identify needs and drive tasks through completion with limited direction
• Experience coordinating vendors, service providers, deliveries, or recurring operational services
• Excellent communication and customer service skills with strong attention to detail and follow-through
• Comfortable working across both office and industrial environments and being hands-on with day-to-day site needs
• Proficiency with Microsoft Office
• Ability to work independently while maintaining strong communication with the Facilities Manager and broader team
• Willingness to support occasional needs outside of standard business hour

Preferred Skills and Experience

• Experience supporting manufacturing, industrial, aerospace, defense, test, or high-growth environment
• Experience managing food, snack, janitorial, or other recurring workplace service programs
• Experience coordinating multiple vendors across multiple properties
• Experience with purchasing, vendor quotes, purchase orders, invoices, and supply management
• Familiarity with facilities ticketing, work order, or project tracking systems such as JIRA
• Experience supporting facilities projects, construction activities, equipment installations, or site improvements
• A resourceful, team-first mindset with a willingness to take on responsibilities outside of a traditional job description as site needs evolve
