Description of the mission

Role Overview

This is not a junior role.

We need someone who can design, validate, and lead. You will oversee system design, mentor engineers, coordinate with sales and project teams, and ensure every system we install performs exactly as modeled.

If you only know how to “draw layouts,” this is not the role.

If you understand yield modeling, inverter loading ratios, grid compliance, and real-world site constraints, keep reading.
