About The Position

Castelion is bringing a new approach to defense development and production: short, iterative design cycles, rapid testing, and modern commercial manufacturing strategies built for scale. We're designing, building, and testing next generation long range weapons systems to give America and its Allies a definitive edge and deter future conflicts. The brand studio you will help build is how the world comes to understand that mission. In the mid-20th century, the defense industry made the impossible look inevitable. Stealth. Precision-guided munitions. Speed that dominated the battlespace. The men and women who visualized those systems and rendered them in ink, gouache, and airbrush before they existed in metal. They gave a generation something to believe in before the hardware could prove it. At Castelion, we believe modern defense manufacturing requires the same new energy around design and illustration. Our Brand Studio is looking for illustrators who want a mission and the freedom to define it.

• Proficiency in Adobe Creative Cloud (Illustrator, Photoshop) and comfort working in Figma for file organization and collaboration; ability to produce clean, production-ready files.
• Ability to work from art direction briefs with meaningful independence, developing fresh interpretations, not just recreating references.
• High attention to craft: Referenced decisions, deliberate composition and consistent quality across deliverables.

Responsibilities

• Create original illustrations & designs for editorial, digital, print, events, recruiting, and internal communications across a range of styles and fidelity levels from concept sketches to finished art.

• Produce technical and semi-technical illustrations of hardware, systems, and environments that are accurate enough to earn the trust of engineers and compelling enough to engage a general audience.

• Develop explainer visuals, cutaway diagrams, and conceptual imagery that translate complex technical subject matter for recruiting, business development, and public communications contexts.
• Contribute to visual research, mood boards, and reference gathering that inform direction across campaigns and initiatives.
• Participate in art direction conversations with the Art Director and Marketing Managers, offering design perspective during creative development.
• Deliver finished files in formats optimized for digital, print, and vendor handoff, properly organized, named, and version-controlled.
• Contribute completed assets to the centralized brand library so they can be adapted and reused across channels without requiring a full redraw.
• Flag scope changes, technical ambiguities, or reference gaps before they affect timelines or quality.
