Our focus is on the design, construction, and evaluation of next-generation long-range strike weapon systems, aimed at providing the United States and its allies with a strategic advantage and deterring potential conflicts.

Senior Power Electronics Engineer

We are in search of a dynamic Senior Power Electronics Engineer to spearhead the architecture, design, and development of power systems utilized in missile technology. This role encompasses both high-level architectural oversight and intricate design responsibilities, delivering power solutions ranging from several watts to kilowatts across various Castelion missile systems. This includes high-power radar seeker systems, brushless DC motors, digital computing units, communication devices, energy storage systems, and other vehicle components. The successful candidate will collaborate closely with Castelion's engineering leadership to architect designs for future vehicles and ground systems. A qualified applicant will possess extensive experience in delivering highly manufacturable power electronics hardware that demonstrates exceptional reliability for mission-critical applications in a dynamic environment.

Key Responsibilities

  • Missile-Level Development: Assume responsibility for the complete power architecture at the missile level. Conduct research and design in accordance with external interface definitions, internal subsystem power predictions, and projected customer needs. Engage in electrical power system and subsystem design evaluations and develop specifications. Define and execute electrical power system verification testing and analysis. Maintain ownership of essential data products (power tree, sequencing diagrams, fault analyses, etc.) to ensure alignment within the broader team regarding power systems. Become the subject matter expert for all power-related matters at Castelion.
  • Seeker-Level Development: The seeker subsystem is expected to present the most challenging power design requirements. Collaborate with the seeker team to create a detailed design that is compliant, cost-effective, feasible, and scalable for manufacturing. Provide engineering expertise in the design, analysis, and testing of DC-DC power converters suitable for harsh operational environments at power levels of several kilowatts.
  • Battery Development: Investigate potential battery chemistries and present comparative analyses to the engineering team. Lead Castelion's battery initiatives through all stages of development, from research and development to prototyping, mass production, and field performance. Oversee technical design at the cell and pack levels, optimizing for safety, performance, cost-effectiveness, and manufacturability.
  • Team Leadership in a Dynamic Environment: Facilitate design reviews and system architecture evaluations for power-related systems. Demonstrate a consistent development progress cadence and prototype design cycles every four weeks. Complete design and requirement assessments ahead of production and leverage high-frequency testing and prototype builds.
  • Implementation and Management of Castelion Avionics Standards: Ensure adherence to modeling, PCBA rules, derating, and naming conventions. Responsible for establishing quality and reliability standards, including EEE part sourcing and acceptance/qualification testing of designs.

Basic Qualifications

  • Bachelor's degree in Electrical Engineering
  • 5+ years of experience in power converter development
  • Prior experience with DC-DC power converter development
  • Experience in modeling, simulation, and testing of power electronics
  • Experience with high-power DC applications (2kW) in compact form factors
  • Experience in modeling, simulation, and testing of power electronics.

Preferred Skills and Experience

  • Missile Experience: Proven ability to design, procure, and integrate flight power systems in missile applications, from initial power assessments to scaled production. Strong understanding of DC-DC topologies, with the capability to select optimal architectures and components. Familiarity with designing for challenging missile environments and knowledge of relevant military specifications.
  • Cost-Effective Design: Demonstrated ability to incorporate cost considerations into both architectural and design decisions, including total component lifecycle costs (part cost, assembly cost, failure rates, reworkability, etc.). Ability to collaborate with cross-disciplinary teams to reduce costs within the system.
  • Full Life-Cycle Development: Ability to creatively address challenges while balancing multi-disciplinary requirements and assessing risks during design and development. Proficient in electrical schematics and electronics manufacturing to enhance test coverage. Hands-on experience with sizing, installing, and troubleshooting various power components.

Leadership Qualities

Proactive and Innovative Problem Solver: A candidate who questions assumptions in ways that lead to innovative solutions that are effectively implemented. Successfully integrate applicable processes, concepts, and materials from diverse industries to achieve efficiency improvements. Capable of independently resolving minor development issues without extensive support.

High Commitment and Initiative: A successful candidate will demonstrate a genuine passion for Castelion's mission and consistently seek ways to contribute to the company's technical objectives while preventing hardware obstacles. Ability to thrive in a fast-paced, autonomous, and demanding environment. Strong sense of accountability and integrity.

Effective Communicator: Proactively address obstacles and communicate effectively. Trusted in previous roles to represent the company with regulators, suppliers, and customers. Skilled in managing stakeholder relationships to achieve desired outcomes while maintaining positive relationships. Communications via email, instant messaging, and verbal interactions are clear, logical, and detailed enough to eliminate ambiguity.
