Sr. Power Electronics Engineer - BNS Core Systems and Components Verified today

About This Role

As a Senior Power Electronics Engineer at Blue Origin, you will architect, design, and deliver the electrical power components for Blue Ring, our multi-mission in-space vehicle. You will work without oversight, lead other engineers, own your program scope, and shape the tools, processes, and standards that define how the team works. Your decisions directly influence mission success.

What You'll Do

Power Systems Architecture and Circuit Design

• Architect and deliver end-to-end electrical power systems for Core Systems and Components, including power generation, energy storage, power distribution, regulation, and fault protection
• Define and own the EPS bus architecture including primary bus topology, voltage domain selection, fault isolation strategy, and power sequencing
• Design power electronics circuits including solar array regulators, battery charge/discharge controllers, DC/DC converters, LDOs, hot-swap controllers, and pyrotechnic firing circuits
• Develop power budgets across mission phases and drive power allocation trades with systems engineering and subsystem owners
• Lead design for derating, worst-case circuit analysis, tolerance analysis, and thermal analysis across your EPS hardware scope
• Define grounding, bonding, and shielding architecture to meet EMI/EMC requirements at the system level
• Guide PCB physical design including power plane strategy, high-current routing, thermal management, and design-for-X requirements

Requirements, Architecture and Documentation

• Lead requirements analysis and architecture definition for EPS subsystems with complete traceability from vehicle-level requirements through circuit-level implementation
• Author and own hardware requirements documents, interface control documents, design specifications, and architecture trade studies
• Independently determine methods and procedures for new EPS design assignments and establish them as standards for the team
• Prepare and chair technical design reviews (SRR, PDR, CDR), driving closure of all findings and action items

Verification, Test and Anomaly Resolution

• Lead development of hardware verification and validation plans with full requirements traceability
• Own environmental qualification and acceptance test strategies for power system hardware
• Lead anomaly investigations and root cause analyses for complex EPS failures and own development and implementation of recovery plans
• Apply technical judgment to evaluate and disposition test anomalies, driving the corrective action process through design resolution

Program Leadership and Ownership

• Own schedule, budget, and technical milestones for your EPS hardware scope; hold program-level technical approval authority
• Lead projects and significant tool development initiatives; own process improvements that increase design efficiency and reduce errors
• Provide support to strategic initiatives including technology roadmapping, EPS architecture maturation, and documentation of best practices

Team Leadership and Mentorship

• Lead, mentor, and train engineers at multiple levels on EPS design, analysis techniques, verification methods, and hardware release criteria
• Review technical work with the ability to detect subtle design flaws and provide actionable improvements
• Develop processes and standards that improve efficiency and quality of EPS design and verification
• Build strong working relationships with systems engineering, mechanical, thermal, software, and test teams

What You Bring

• B.S. in Electrical Engineering or closely related field
• 8 or more years of experience designing and delivering electrical power systems hardware through the full development lifecycle from requirements and architecture through fabrication, qualification, and production
• Experience architecting and designing spacecraft or high-reliability EPS hardware including power generation interfaces, energy storage systems, power distribution units, and regulation circuits
• Deep understanding of power electronics design including DC/DC converters (buck, boost, buck-boost, flyback), battery management, and fault protection circuits
• Experience performing and leading derating analysis, worst-case circuit analysis, tolerance analysis, and thermal analysis for flight or high-reliability power hardware
• Experience defining and implementing grounding, bonding, and shielding architecture for complex electronic systems
• Experience leading technical design reviews (PDR, CDR) and owning documentation and action item closure
• Experience leading root cause analyses and anomaly investigations for complex hardware failures
• Demonstrated ability to mentor and provide substantive technical feedback to other engineers
• U.S. citizenship or permanent resident status required for access to export-controlled technical data

Preferred Qualifications

• M.S. or Ph.D. in Electrical Engineering or related field
• Experience designing EPS hardware for spacecraft, in-space propulsion systems, or launch vehicle avionics
• Experience with solar array power system design including maximum power point tracking and array-to-bus regulation architectures
• Knowledge of battery electrochemistry, cell-level characterization, and battery management system design for Li-ion or Li-polymer flight batteries
• Familiarity with fault protection architecture design including autonomous fault detection, isolation, and recovery strategies
• Experience designing pyrotechnic or electro-explosive device firing circuits for spacecraft separation or deployment systems
• Knowledge of radiation effects on power electronics and experience selecting or qualifying radiation-tolerant components
• Experience with power system modeling and simulation using MATLAB/Simulink, SPICE-based tools, or Systems Tool Kit
• Familiarity with MIL-STD-975, MIL-PRF-38535, ECSS, or equivalent hi-rel parts qualification and screening standards
• Experience defining and executing EMI/EMC test programs for power systems hardware (MIL-STD-461 or equivalent)
• Background in high-speed PCB physical design including PDN analysis, signal integrity, and thermal management for multi-layer flight boards
• Familiarity with AS9100, NASA-STD-8739, or IPC-A-610 quality and workmanship standards
• Experience supporting production transitions including first article inspection, DFM optimization, and production acceptance test development
• Experience developing or owning discipline-level design processes, tools, or standards
• Familiarity with MBSE and requirements management tools such as DOORS, Cameo, or Jama
