As the EHS & S Manager, you will own the full Environmental, Health, Safety & Security (EHS&S) function at our Houston manufacturing facility - from OSHA and environmental regulatory compliance to hazard-specific programs covering high-voltage electrical testing, transformer oil/dielectric fluid handling, overhead crane operations, and hot work. You'll also serve as the site lead for physical security, access control, and emergency preparedness.

You'll work closely with plant leadership, production supervisors, and corporate HSE to build a proactive safety culture and keep the facility fully compliant with federal, state, and local requirements.

We are an in-office culture - velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is based full-time on-site at our Houston, TX manufacturing facility, with regular presence on the production floor, testing areas, and warehouse/yard.
