The Role

T1 Energy is looking to hire a Senior Director to lead the HR function for our G1 solar module facility in Wilmer, TX.

You'll be the person who makes sure G1 is not just productive, but a place people want to work, and you'll build the systems and team to sustain that a we scale. If you've led HR at a large manufacturing or industrial site and you want real ownership of a facility's people function, this role was built for you.
