Summer 2027 – Power Electronics Internship

About the role

At CesiumAstro, we develop pioneering communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. The Analog & Power Electronics team designs advanced power electronics for space and military products, overseeing the full development cycle—from power architecture and part selection to schematic and PCB design, verification testing, and production release. This includes power conversion, management and control, fault management, and filtering for low noise and EMC. We are seeking summer interns to work side‑by‑side with experienced engineers on design projects that contribute to ongoing programs or advance the team’s technology roadmap, gaining hands‑on laboratory characterization and troubleshooting experience.

Responsibilities

• Work side‑by‑side with experienced power electronics engineers on design projects that directly contribute to ongoing programs or advance the Analog & Power Electronics team’s technology development roadmap.
• Gain valuable experience in hands‑on laboratory characterization and troubleshooting of power electronics.

Requirements

• Must be a U.S. citizen, lawful permanent resident, conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.
• 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 electronics and completion of course work in one or more of the following areas: power electronics, modeling and control of power electronics, control theory, linear systems theory, non‑linear system theory, power systems, and analog electronics.
• Knowledge of different DC‑DC power converter topologies (e.g., discrete linear regulator, Buck, Buck‑boost, Flyback, Forward, Half‑bridge, Full‑bridge).
• 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 analysis and simulation tools such as SPICE, LTSPICE, SIMetrix/SIMPLIS, PLECS, Simulink, MATLAB, MathCAD, ANSYS Q3D and SiWave, or HyperLynx.
• Excellent written and verbal communication skills.

Skills

• Practical experience designing and building power electronics hardware for a research project, competition team, extracurricular activity, prior internship, or an advanced electronics engineering course.
• Experience with electronics schematic capture and printed circuit board (PCB) layout tools such as Altium, OrCAD, Allegro or Xpedition.
• Experience with power magnetics modeling, design and laboratory characterization.
• Experience with voltage mode or peak current mode control, including control loop modeling and laboratory characterization.
• Experience in power electronics applications utilizing GaN or SiC wide bandgap power semiconductor devices.
• Knowledge of soft switching and resonant power converter topologies (e.g., LLC, CLLC, series resonant, phase‑shifted full bridge, dual active bridge, etc.).
• Programming skills to support hardware test and data processing (Python, MATLAB, etc.).

Benefits

All CesiumAstro internships are compensated competitively and located onsite at one of our facilities.
