Avionics Internship- Power Electronics (Spring or Summer 2027)

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge. For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles. Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more. We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.

We are seeking talented engineers to work closely with the broader engineering team for an exciting internship opportunity. This person is passionate about engineering, ready to take ownership over complex challenges, and a strong desire to learn about all things satellites. During the 12-week internship program at Apex, you'll gain hands-on experience and professional growth opportunities. You’ll be assigned a project to give you the opportunity to have real impact. Throughout the project you'll have a dedicated mentor to guide you, while participating in learning sessions to elevate your knowledge of aerospace. Plus, you'll connect with peers and industry professionals during our community events, making this a well-rounded experience to launch your career! Power Electronics : Interns will contribute to spacecraft power electronics testing and hardware development. This includes: Design, Build, and Testing non isolated and isolated power converters for high reliability space applications. May include motor controller work as well. Simulation of the power stage in SPICE Modeling the plant and designing the controller for a given topology and control technique (voltage, peak current, average current mode) Schematic capture, jumping into component selection and auxiliary features of the converter Layout, using Altium to place components on the board and connecting them in an optimized way. Bench top testing the circuits at the board level using common lab equipment (power supplies/E-loads/oscilloscopes/Bode100) Specialized power converter testing, EMI/EMC and control loop verification Control loop tuning, either in analog or digitally Requirements: Graduating in the Fall of 2027 or in the Spring of 2028. MS graduates preferred Pursuing a BS or MS in Power Electronics or Embedded Systems or Control Proficiency in LT Spice, Altium, MathWorks, C2000 microcontrollers Preferred coursework Introduction to Power Electronics, Introduction to Linear/Continuous Control, Introduction to Motor Drives Preferred Extracurricular Activities: Student Project Teams, ie Formula SAE Note: Spring interns should be available to pause or adjust academic commitments (such as taking a semester off or enrolling part-time) for the duration of the program Why Join Apex?
