- Dimension and model power supplies, DC/DC converters, batteries, protections, and power distribution units.
- Contribute to power budget analyses, including worst-case, safe mode, and redundancy scenarios.
- Investigate non-conformances and drive corrective action plans related to electrical and EPS systems.

PCB & Harness Development

- Design or supervise the design of electronic boards (schematics, component selection, routing, justification files).
- Lead the development and validation of dedicated avionics boards such as EPS, PDU, or payload interface boards.
- Define and document harness architectures, wiring diagrams, and electrical integration rules.
- Ensure consistency between electrical equipment and overall system architecture.
- Support root cause analyses and corrective actions on avionics hardware.

Supplier Management, Manufacturing & Testing

- Prepare technical specifications for electrical and power equipment procurement.
- Manage suppliers and subcontractors involved in PCB, harness, and electrical equipment manufacturing.
