Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and deliver high-performance mechanical actuation systems and control surface mechanisms for hypersonic strike vehicles. Lead the architecture and validation of gear trains and linkages while collaborating with multidisciplinary teams to ensure seamless vehicle integration.
Requires a degree in Mechanical Engineering and 5+ years of experience in aerospace mechanism design and electromechanical actuators. Proficiency in CAD and analysis tools, along with the ability to obtain a U.S. security clearance, is essential.
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.
We are seeking a Senior Mechanisms Engineer to design and deliver high-performance mechanical actuation systems for Castelion's long-range hypersonic strike vehicles. This role is critical to enabling precise and reliable control surface motion and deployment mechanisms under extreme flight conditions. You will work hands-on with multidisciplinary engineering teams to design, analyze, build, and validate mechanisms such as elevon drive trains and related actuation systems in a fast-paced, hardware-driven environment.
Please note this job description is not designed to cover or contain a comprehensive listing of activities, duties or responsibilities that are required of the employee for this job. Duties, responsibilities and activities may change at any time with or without notice.
All full-time employees are granted meaningful long-term equity, sharing in the company's significant growth trajectory. We offer four (4) weeks of paid time off, ten (10) company-paid holidays, and comprehensive health benefits - including 100% employee-covered medical and strong dependent coverage, along with dental and vision plans. We also provide paid parental leave to support growing families, a $100 monthly fitness stipend to promote health and performance, and onsite EV charging for convenience. In addition, employees enjoy perks like catered meals, company-covered food during high-demand periods, and a fully stocked kitchen to stay fueled throughout the day.
While this position does not currently require a U.S government-issued security clearance, it may in the near future. Therefore, the ability to obtain and maintain a U.S. government–issued security clearance is required. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.
Employment with Castelion is governed on the basis of competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.
