Spring 2026 - Specialty Engineering Internship

CesiumAstro•El Segundo, CA

23h•Onsite

About The Position

At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We foster a dynamic and cross-functional work environment that encourages learning, development, and engagement. We are seeking passionate, collaborative, energetic, and forward-thinking individuals. The CesiumAstro Specialty Engineering Team is responsible for performing specialty analysis and test across disciplines including component, radiation, materials and process, reliability, and EMI/EMC engineering to support all CesiumAstro products, particularly cutting-edge space electronics. The team manages specialty requirements from initial concept through manufacturing, test, delivery, on-orbit support, and anomaly analysis, covering high-speed digital, power electronics, and RF hardware designs. This internship offers hands-on, interactive, and autonomous work, with interns working alongside staff specialty engineers on active space electronics design projects. Specific assignments will be determined by project availability and candidate interests. The role includes potential assignments in Radiation Engineering, providing end-to-end support for mechanical and electrical engineering teams, with tasks ranging from natural space radiation environment definition and shielding to component performance and circuit analysis of single event effects. It also includes potential assignments in Component Engineering, assisting electrical engineering designers in identifying components that meet performance requirements and survive harsh space environments while balancing cost and lead time, with tasks such as building data integration tools, optimizing bill-of-material costs, and assessing component performance and reliability. This position is ideal for electrical engineering, physics, or similar discipline students passionate about space electronics design.

Requirements

Current enrollment in a Bachelor of Science (BS), Master of Science (MS), or PhD program in Electrical Engineering or Computer Engineering from an accredited university.
Strong fundamentals in EE or physics topics covered in coursework.
Practical experience designing and building electronics hardware for a research project, competition team, extracurricular activity, prior internship, or advanced engineering course.
Hands-on experience with lab instruments such as oscilloscopes, spectrum analyzers, electronic loads, and signal generators.
Excellent written and verbal communication skills.
