Director of Plant Operations

Hexegen has proven its process for producing high-purity, graphene-class carbon nanomaterials. Our Tomball prototype reactors validated both product quality and the repeatability of the reaction. The next build takes that proven chemistry, automates it, and scales it — and it is designed from the outset to be replicated, so that the plant we build in Tomball becomes the template for Hexegen facilities anywhere in the world.  

We are hiring a Site Director to lead that work. You will be Hexegen's senior leader on the project: representing our interests through design, construction, and commissioning alongside our engineering partner, then running the facility as a safe, reliable, high-yield operation. Build it once, build it right, and you have built the standard for every Hexegen plant that follows.

Hexegen is a Texas-based advanced materials company and a subsidiary of Nabors Industries (NYSE: NBR). We are commercializing the Hexite™ platform — a proprietary process for producing high-purity, graphene-class nanomaterials at scale. 

For twenty years, graphene has been chemistry's most over-promised category. The properties are extraordinary — strength, conductivity, surface area no other material approaches — but the field has stalled on a recurring set of problems: processes that don't scale, products that aren't pure, feedstocks that aren't economic, and chemistries you can't tune to a specific application. 

Hexite™ addresses all four. Our Tomball prototype has been producing high-purity material since 2024 from readily available, low-cost inputs, with process control tight enough that we can engineer the molecule for the application at hand. That tunability is what opens the market: Hexite™ materials target thermoplastics, construction, energy storage, automotive, aviation, defense, and medical applications, with hydrogen technologies on the roadmap. 

Responsibilities

Where We Are 

The prototype is built and running. It has demonstrated that we can make Hexite™ to specification and make it the same way every time. The chemistry question is closed. 

The next facility automates that process and adds capacity. Much of the production system has already been designed, and we have engaged a third-party engineering firm to complete the design and manage construction of the reactor system and facility. 

That facility is also our reference design. It is intended to scale in place as demand grows, and to be replicated at future sites — including internationally. Decisions made during this build will be inherited by every plant that follows. 

What You Will Do 

This role is Hexegen's owner's representative on the capital project — accountable for the outcome, not for the drafting. You will hold the design accountable to operability, safety, cost, and replicability. You will own commissioning and startup. You will then run the plant you helped build, and it will become the model we hand to the next site.
