Senior Dual Voltage Distribution Box Responsible Engineer – TeraWave

About the role

TeraWave is a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. The DVDB is a critical EPS component responsible for distributing and protecting spacecraft power loads across two voltage domains, providing switchable power outputs, fault isolation, telemetry, and load management across the vehicle.

Responsibilities

• Own the full design, development, qualification, and production release of the Dual Voltage Distribution Box, including requirements derivation, circuit design, schematic capture, layout oversight, and design verification
• Define and maintain hardware requirements, interface control documents (ICDs), and design specifications in coordination with systems engineering and adjacent subsystems (thermal, structures, harness, avionics, and all powered loads)
• Lead dual-voltage power distribution circuit design — including solid-state power controllers (SSPCs), relay-based switching, overcurrent protection, in-rush current limiting, and fault isolation — across both voltage domains of the spacecraft power bus
• Define load switch sequencing, priority shedding logic, and fault response behavior in coordination with the Fault Management and C&DH teams
• Own the DVDB telemetry architecture — including current, voltage, and switch state monitoring — and define interfaces with the spacecraft avionics for health monitoring and commanding
• Design for constellation-scale production: optimize for manufacturability, testability, component availability, and unit cost while meeting reliability and performance requirements
• Guide and transition Automated Test Equipment from development to production, ensuring adequate fault coverage and load switching verification capability for rate manufacturing
• Manage and maintain full design documentation including schematics, PCB layouts, BOMs, drawings, and analysis reports within the PLM system
• Own qualification testing per applicable standards (MIL-STD-1540, SMC-S-016, or equivalent), including test plan development, execution oversight, and anomaly resolution
• Support vehicle integration, troubleshoot anomalies, and support flight acceptance testing across all powered interfaces
• Manage and maintain full design documentation including schematics, PCB layouts, BOMs, drawings, and analysis reports within the PLM system

Requirements

• Bachelor's degree in Electrical or Computer Engineering or related field with 7+ years of direct experience in electronics hardware development
• Demonstrated design experience with power distribution architectures, solid-state power controllers (SSPCs), relay switching, overcurrent protection, and fault isolation across multi-voltage spacecraft bus domains (>50V)
• Experience with load management, switch sequencing, in-rush current mitigation, and priority load shedding in high-reliability power distribution systems
• Experience designing to EMI/EMC requirements (MIL-STD-461 or equivalent) including conducted emissions, radiated emissions, and susceptibility
• Experience designing fault-tolerant power electronics for high-reliability applications, including FMEA/FMECA participation and single-point failure elimination
• Experience leading or significantly contributing to hardware qualification campaigns per MIL-STD-1540, SMC-S-016, ECSS-E-ST-10-03, or equivalent
• Experience with radiation-tolerant or radiation-hardened design techniques for space environments, including component selection, shielding analysis, and total ionizing dose (TID) considerations
• Demonstrated ability to own a hardware product end-to-end with minimal oversight — from requirements through qualification and production release
• Hands-on experience with the understanding of full product development lifecycle of electronics hardware

Qualifications

• Ability to work independently and as part of a team on rapid development programs
• Strong understanding of electronics design and integration with mechanical systems for structural and thermal support
• Experience using Altium (or similar tools) for schematic capture and layout
• Experience using LTspice (or similar tools) for circuit simulations
• Experience with Windchill PLM or equivalent configuration management systems
• Experience with safety-critical systems development (automotive, aerospace, medical, etc.)

Skills

• Ability to travel to and work at remote sites supporting test integration, commissioning, and training (~20% travel)
