About The Position

Moog’s Space and Defense Group is seeking an experienced Senior Spacecraft Avionics, Power and Wiring (APW) Engineer for its Space Vehicles team in Arvada, Colorado. The role covers spacecraft development from conceptual design through development, integration, testing, and delivery. Typical applications include spacecraft buses, a smart upper stage, an in-space transfer vehicle, and a hosted payload platform. The selected engineer will lead the power subsystem and work collaboratively with engineers across disciplines, reporting to the Systems Engineering Manager. The position follows a hybrid 9/80 schedule, with every other Friday off. The engineer will develop and manage spacecraft avionics, electrical power, and wiring architectures, requirements, interfaces, analyses, designs, and verification activities throughout the program lifecycle. The role also provides technical leadership and supports suppliers, procurement, manufacturing, integration, testing, troubleshooting, proposals, and delivery.

Requirements

Bachelor’s degree in electrical engineering or a closely related engineering discipline.
At least 5 years of relevant aerospace electrical engineering experience.
Experience defining or integrating avionics, command-and-data-handling, electrical power, and harness architectures.
Experience developing and interpreting electrical schematics, block diagrams, interface-control documents, I/O assignments, connector pinouts, and wiring or harness drawings.
Experience performing spacecraft electrical analyses, such as power budgets, battery and solar-array sizing, and voltage drop analysis.
Experience supporting electrical hardware through requirements, design, procurement, manufacturing, integration, testing, troubleshooting, and delivery.
Experience leading technical teams, design reviews, supplier oversight, trade studies, and anomaly investigations.
Strong written and verbal communication skills, including presenting technical information to multidisciplinary teams, leadership, customers, and suppliers.
Ability to support occasional travel and off-shift testing and support when required.

Nice To Haves

At least 7 years of spacecraft or high-reliability aerospace electrical systems experience, including 3 or more years of direct spacecraft avionics, electrical power, and/or wiring experience.
Demonstrated technical ownership of a spacecraft avionics or APW subsystem through design, integration, environmental test, and delivery.
Experience with redundant and fault-tolerant avionics architectures, command and telemetry interfaces, time synchronization, and hardware-to-flight-software interfaces.
Knowledge of grounding, bonding, shielding, isolation, fault protection, EMC/EMI, workmanship, and verification principles and standards.
Experience with spacecraft data buses and electrical interfaces such as SpaceWire, CAN, MIL-STD-1553, Ethernet, RS-422/485, or comparable protocols.
Knowledge of radiation effects and radiation-tolerant avionics design considerations.
Experience with spacecraft EMI/EMC design, analysis, troubleshooting, and testing.
Experience with electrical simulation, analysis, ECAD, or harness-design tools.
Experience with lithium-ion batteries, solar arrays, spacecraft power electronics, or high-energy electrical systems.
Experience performing component derating, power quality, and worst-case circuit analyses.

Responsibilities

Develop and maintain a system-level understanding of spacecraft bus APW architectures, interfaces, operating modes, and mission constraints.
Define and manage spacecraft avionics architectures, including flight computers, command and data handling, data-acquisition hardware, data buses, time synchronization, and command, telemetry, analog, discrete, and digital interfaces.
Define spacecraft electrical power architectures, including generation, energy storage, regulation, distribution, switching, grounding, redundancy, load shedding, and fault protection.
Perform trade studies and electrical analyses, including power budgets, mission load profiles, solar-array and battery sizing, component derating, voltage drop, power quality, inrush current, and worst-case circuit analyses.
Develop and maintain functional block diagrams, electrical schematics, interface-control documents, I/O and power-switching assignments, connector pinouts, and cable and harness designs.
Define grounding, bonding, shielding, isolation, cable separation, wire sizing, connector selection, and harness-routing requirements.
Coordinate APW requirements and interfaces with systems engineering, flight software, GNC, communications, payload, thermal, mechanical, propulsion, and other spacecraft disciplines.
Develop and manage APW requirements, technical baselines, verification plans, and fault-detection, isolation, and recovery approaches throughout the program lifecycle.
Work with Moog Supply Chain and suppliers of avionics, power electronics, batteries, solar arrays, harnesses, and other electrical hardware to support procurement and provide technical oversight.
Prepare and present technical content for trade studies, design reviews, test-readiness reviews, customer presentations, and proposals.
Develop and support electrical ground support equipment (EGSE), integration plans, test procedures, and verification documentation in coordination with other disciplines.
Support manufacturing, integration, functional and environmental testing, EMC/EMI testing, troubleshooting, anomaly resolution, and delivery of the APW subsystem.
Provide technical leadership and mentorship while supporting program cost, schedule, risk, and proposal activities.
Support occasional travel and off-shift testing and support when required.
