- Experience preparing and executing customer-facing design reviews.
- Ability to support supply chain, manufacturing, and test organizations in design release.
- Excellent communication and technical documentation skills.
Desired Skills & Experience
- Familiarity with radiation effects on power electronics and mitigation techniques.
- Knowledge of space-grade standards (e.g., MIL-STD-704, MIL-STD-461, IPC-2221, NASA/ECSS requirements).
- Experience with fault tolerance, redundancy, and high-reliability design practices.
- Hands-on experience with lab testing of power hardware (oscilloscopes, power analyzers, thermal chambers, etc.)
