Senior Power Electronics Engineer
About The Position
Castelion is seeking a Senior Power Electronics Engineer to develop and integrate advanced electrical power systems for its long-range hypersonic strike vehicles. The role supports reliable power generation, storage, and distribution for mission-critical avionics and vehicle subsystems. The engineer will work hands-on with multidisciplinary teams to design, analyze, test, and validate power electronics hardware in a fast-paced, hardware-driven environment. The position may require access to classified information or restricted U.S. Government sites, systems, or information; if designated, employment may depend on obtaining and maintaining required clearances or authorizations and meeting applicable eligibility requirements. The role also requires access to export-controlled information, so employment is contingent on the candidate being able to access applicable information without additional export licensing.
Requirements
- Bachelor's, Master's, or PhD in Electrical Engineering or a related field.
- At least 5 years of experience in power electronics design, analysis, and validation for aerospace, defense, or other high-reliability systems.
- Strong background in battery systems, DC-DC power conversion, and power distribution architectures.
- Experience designing power controllers and power management systems for embedded or avionics applications.
- Proficiency in circuit design, simulation, and analysis tools such as SPICE, MATLAB/Simulink, or equivalent.
- Experience with hardware bring-up, testing, and troubleshooting in a lab or flight hardware environment.
- Familiarity with thermal management, EMI/EMC considerations, and ruggedized electronics design.
- Strong problem-solving skills and ability to thrive in a fast-paced, hardware-rich environment with a high flight cadence.
- Ability to access applicable export-controlled information without requiring additional export licensing.
Responsibilities
- Design and develop power electronics systems, including battery architectures, power conversion, and distribution for high-performance flight vehicles.
- Lead the design and optimization of power controllers and power management systems for stable, efficient operation across mission phases.
- Develop and analyze battery systems, including selection, packaging, thermal considerations, and safety mechanisms for demanding environments.
- Coordinate with avionics, GNC, and flight software teams to integrate power systems with vehicle subsystems.
- Conduct circuit-level and system-level modeling and simulation to evaluate performance, efficiency, and reliability under dynamic conditions.
- Support hardware bring-up, integration, and test campaigns, including troubleshooting and root cause analysis.
- Define and execute qualification and flight test plans and translate results into system-level improvements.
- Mentor junior engineers and contribute to power electronics design best practices.
- Partner with program leadership on technical tradeoffs aligned with mission success.
Benefits
- Generous benefits package; details are available at the bottom of Castelion's Careers page.
