• Prepare detailed schematics, engineering calculations, design notes,and Bills of Materials.
• Perform circuit analysis and simulation using suitable simulation and design tools.
• Implement fault detection, isolation, recovery, redundancy, current limiting, and protection features as required by the mission.

EMI/EMC, Signal Integrity and Power Integrity

• Implement grounding, shielding, filtering, isolation, and protection techniques to meet spacecraft EMI/EMC requirements.
• Perform signal-integrity and power-integrity analysis for high-speed interfaces, memory buses,clocks, and power rails.
• Define controlled-impedance, termination, routing,stack-up, grounding, and decoupling requirements for PCB layout.
• Review PCB layouts, fabrication data, Gerber files, ODB++ data, assembly drawings, and manufacturing outputs.
• Perform electrical stress analysis,worst-case circuit analysis,tolerance analysis, and component derating analysis.

Documentation and Manufacturing Support

• Prepare module-level and PCB-level assembly drawings.
• Prepare detailed wiring diagrams, interface-control documents, connector pinouts, and cable-harness requirements.
• Prepare hardware design descriptions, test procedures, verificationdocuments, compliance matrices, anddesign-review presentations.
• Prepare electrical power-dissipation data and input documents for thermal and mechanical analysis.
• Coordinate with PCB-layout, mechanical, thermal, firmware, FPGA, manufacturing, quality, andsystem-engineering teams.
• Support fabrication, assembly, inspection, rework, and high-reliability manufacturing of PCBs and electronic modules.
• Support component procurement, alternate-part evaluation, counterfeit-risk mitigation, and parts approval processes.

Testing, Qualification and Integration

• Develop module-level and system-level hardware test plans and test procedures.
• Perform board bring-up, debugging, functional testing, performance validation, and failure analysis.
• Support environmental and qualification testing, including:
  • Thermal testing
  • Vibration and mechanical-shock testing
  • EMI/EMC testing
  • Burn-in and reliability testing
  • Radiation testing, where applicable

• Support engineering-model, qualification-model, flight-model, and proto-flight-model integration.
• Analyze test failures and implement corrective and preventive design actions.
• Incorporate engineering changes identified during development, integration, environmental testing,and qualification.
• Participate in design reviews such as PDR, CDR, TRR, QR, and FRR.

Design and Analysis

• Schematic-capture and PCB-design tools
• SPICE-based circuit simulation
• Signal-integrity and power-integrity analysis
• Worst-case circuit analysis
• Electrical stress and component derating analysis
