Sr. Power Electronics Engineer - BNS Core Systems and Components

## Application close date Applications will be accepted on an ongoing basis until the requisition is closed. At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion.

Join our team of problem solvers as we add new chapters to the history of spaceflight! This role is part of Blue National Security (BNS), where our focus is the design, development, and delivery of launch and spacecraft systems for national security missions.

Through Blue Ring, our all-in-one, high-powered hybrid solar-electric and chemical-propelled spacecraft, we provide unmatched mission maneuverability, versatility, and capacity at dramatically lower-profile costs. ## About This Role At Blue Origin, we believe in a future where millions of people live and work in space.

Blue Ring (our multi-mission in-space vehicle) is a cornerstone of that future, and the electrical power system that sustains it must perform flawlessly across a wide range of missions and environments. As a Senior Power Electronics Engineer, you will architect, design, and deliver the electrical power components that keep Blue Ring (and similar systems) alive in space.

You'll work without oversight, lead other engineers, own your program scope, and shape the tools, processes, and standards that define how our team works. This is a role with real impact, your decisions directly influence whether we achieve our mission objectives. If you don't meet every qualification listed, we encourage you to apply.

We know exceptional engineers come from many different backgrounds, and we value the perspective and experience you bring. ## Power Systems Architecture & Circuit Design · Architect, design, and deliver end-to-end electrical power systems for Core Systems and Components, Space Mobility avionics, 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 across vehicle modes and mission phases · Design power electronics circuits including solar array regulators, battery charge/discharge controllers, DC/DC converters, LDOs, hot-swap controllers, and pyrotechnic firing circuits for flight applications · Develop power budgets across mission phases and drive power allocation trades with systems engineering and subsystem owners · Decompose and allocate system-level EPS requirements into subcircuit and module-level requirements across interconnected, integrated electronic assemblies · Lead design for derating, WCCA, 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 DfX requirements for flight hardware ## Requirements, Architecture & Documentation · Lead requirements analysis and architecture definition for EPS subsystems, ensuring complete traceability from vehicle-level requirements through circuit-level implementation · Author and own hardware requirements documents, interface control documents (ICDs), design specifications, and architecture trade study documentation · 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) for EPS hardware, including driving closure of all findings and action items ## Verification, Test & Anomaly Resolution · Lead the development of hardware verification and validation plans with full requirements traceability for your EPS scope · Own environmental qualification and acceptance test strategies for power system hardware · Lead anomaly investigations and root cause analyses for complex EPS failures, and own the development and implementation of recovery plans · Apply advanced technical judgment to evaluate and disposition test anomalies, driving the corrective action process through design resolution ## Program Leadership & Ownership · Own schedule, budget, and technical milestones for your EPS hardware scope;
