Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Develop, test, and debug low-level firmware and device drivers for missile systems and flight hardware. Collaborate with cross-functional teams to perform hardware bring-up and hardware-in-the-loop validation.
Must be a U.S. Person pursuing a BS or MS in Computer Engineering, Electrical Engineering, or Computer Science. Requires strong C/C++ skills and experience with microcontrollers, SoCs, and common communication protocols.
Castelion is bringing a new approach to defense development and production: one that focuses on short, iterative design cycles, rapid testing in development, and modern commercial manufacturing strategies for production at scale. We're designing, building, and testing next generation long range strike weapons systems to give America and its Allies a definitive edge and deter future conflicts.
Embedded Software Engineer Intern - Fall 2026
Castelion is seeking motivated and talented Embedded Software Engineering interns for Fall 2026. You'll help create the software that drives and simulates our missile systems, from low-level firmware on microcontrollers to high-level integration and testing tools. You'll work alongside experienced embedded, hardware, and flight systems engineers to design, implement, test, and debug real systems in the loop.
You wont be writing throwaway code; your contributions will directly support our rapid prototyping and real-world tests.
At Castelion, you'll be part of a mission-driven company where every project matters. Our interns don't just observe. They contribute meaningfully to the success of our programs. This is a unique opportunity to work at the cutting edge of aerospace engineering while developing the skills and experience that will help you grow into a future leader in the field.
