Urgent! Sr Power Electronics Engineer – II (R&D)

About Orbitt Space

Orbitt Space is developing next-generation electric propulsion systems and advanced power electronics for ultra-low Earth orbit (ULEO) satellites. Our work focuses on plasma thrusters, High Voltage Power Systems, and GaN-based high-frequency power converters — pioneering technology for sustainable access to space.

Role Overview

We are seeking a Power Electronics Engineer – II (R&D) with hands-on experience in wide bandgap (GaN) device-based dc-dc converter design and MHz-range RF power electronics.

You will design, develop, and test high-frequency RF generators and advanced converter topologies including Class E, Class EF, half-bridge, and full-bridge systems for plasma propulsion and wireless power transfer applications.

This is a core R&D role where your innovations will directly influence the next generation of Orbitt’s propulsion and energy systems.

Key Responsibilities

• Design and develop RF power generators operating in the MHz frequency range for plasma thrusters.
• Develop and optimize GaN-based high-frequency converter topologies (Class E, EF, half-bridge, full-bridge, Matching network design).
• Design custom gate driver circuits and switching mechanisms for wide bandgap devices.
• Work on resonant and soft-switching converter architectures using MATLAB / Simulink, LTspice, Orcad or PLECS.
• Design and validate inductive power transfer systems at MHz frequency range.
• Interface with DSP controllers (TI C2000x) for converter control and modulation.
• Perform bench-level testing, debugging, and characterization using oscilloscopes, spectrum analyzers, and network analyzers.
• Design analog and mixed-signal circuits using Op-Amps, ADCs, PWM controllers, and gate drivers.
• Document test results, design methodologies, and contribute to technical reports for grants and investors.
