Zusammenfassung

E-Space is seeking Power Electronics Engineers to design and qualify power subsystems for a next-generation satellite constellation. You will design and qualify power distribution, battery management, charge regulation, and power conditioning across multiple avionics boards, applying deep analog and space-grade design rigor.

The role requires designing DC/DC converters, battery management, and control-loop compensation, with experience in radiation-tolerant hardware and thorough circuit

Qualifikationen

• Bachelor’s or Master’s degree in Electrical Engineering or related field.
• 5+ years of experience in power electronics design for aerospace, defense, or high-reliability systems.
• Proven experience designing DC/DC converters, LDOs, and power distribution systems.
• Strong understanding of control-loop theory (analog and digital compensation, stability analysis).
• Experience with fault protection design and safe operating area analysis.
• Proficiency with circuit simulation tools (SPICE, LTSpice, or equivalent).
• Knowledge of component derating standards and radiation tolerance considerations for space applications.

Aufgaben

• Design DC/DC converter power stages including switching device selection, filter design, driver circuits, and magnetics.
• Develop battery management and charge regulation circuits with appropriate safety, cycle-life, and charging-profile considerations.
• Perform control-loop modeling and compensation for analog and digitally controlled power supplies.
• Design fault-protection circuits including overcurrent break, current clamp, overvoltage clamp, crowbar, and foldback protection.
• Implement current, voltage, and temperature sensing circuits with filtering, threshold triggers, and ADC integration.
• Perform component derating analysis and design for radiation tolerance across all power subsystems.
• Develop load accounting, mode-based power consumption estimates, and concept-of-operations power budgets.
• Design power distribution networks with DC load switches, telemetry, and protection for multiple subsystem loads.
• Collaborate with PCB layout engineers on power supply layout optimization (loop area minimization, noise reduction, switching node management).
• Support FPGA and digital teams with power supply sequencing, support circuitry, and power integrity requirements.
