Summer 2026 – Power Electronics Internship

Summer 2026 – Power Electronics Internship

CesiumAstro is looking for summer 2026 interns to design and build electronics hardware for satellite communication systems. On the CesiumAstro Analog & Power Electronics Design Team, we are responsible for electronic circuits through all stages of the development process for cutting-edge space and military electronics. We own designs from initial concept through part selection, schematic capture, printed circuit board (PCB) design, build, test, and delivery, all the way through production support. Designs encompass the spectrum of electronics design, including high-speed digital, analog, power electronics, and RF hardware – often on the same board.

We're looking for summer interns to support our mission. Interns work side-by-side with design engineers: contributing to the company's success is as high of a priority as learning and gaining experience. Interns are typically paired with an experienced engineering mentor and are responsible for design projects that directly contribute towards an on-going program or contribute towards advancing the Analog & Power Electronics team's technology development road map. Interns will also gain valuable experience in analysis and hands-on laboratory characterization and troubleshooting of electronic circuits. Specific assignments will be determined by a mix of project availability, candidate skillset and interests.

If you are an electrical engineering student with a passion for analog or power electronics and who wants to sink your teeth into the rigor of space and military electronics design, this is the job for you. To apply, please include a brief cover letter describing your interest in power or analog electronics hardware design and in this role. We are looking to add teammates who share our passion!

Requirements and Minimum Qualifications

• Current enrollment in a Master of Science (MS), or PhD program in Electrical Engineering or Computer Engineering from an accredited university with a focus in analog or power electronics.
• GPA of 3.5 or higher.
• Strong fundamentals in EE topics covered in coursework, and completion of one or more of the following course topics: power electronics, modeling and control of power electronics, control theory, linear systems theory, non-linear system theory, power systems, and analog electronics.
• Practical experience designing and building electronics hardware for a research project, competition team, extracurricular activity, prior internship, or advanced engineering course.
• Familiarity with electronics schematic and layout tools such as Altium.
• Hands-on experience with lab instruments such as oscilloscopes, spectrum analyzers, frequency response and impedance analyzers, electronic loads, power sources, and signal generators.
• Experience with one or more circuit simulation and modeling tools such as LT SPICE, Q-SPCIE, SIMetrix/SIMPLIS, ANSYS Maxwell, ANSYS Q3D, MathCAD, MATLAB/Simulink
• Excellent written and verbal communication skills. Cesium interns regularly present their work to peers, mentors, and Cesium executive leadership throughout the course of the summer.

Preferred Experience

• Experience with PCB layout.
• Experience with magnetics design, modeling, and characterization.
• Advanced coursework or research experience in power electronics and power converter applications utilizing GaN or SiC wide bandgap devices.
• Strong programming skills to support hardware bring-up and test (C/C++, Python, MATLAB, etc.).

All CesiumAstro internships are compensated competitively and located onsite at one of our facilities. CesiumAstro is an Equal Opportunity employer.
