Key Account Manager

About us

We are a pre-IPO company backed by a distinguished group of strategic partners and some of the world’s most influential climate tech funds. With strong traction in shipments and several major customer wins, the market now recognizes the value of our technology and the impact it will have on the future of the industry.

We have a world-class R&D organization, an extensive patent portfolio and a strong leadership team which is scaling the company up across all functions. We are headquartered in Austin, TX, and have a state-of-the-art manufacturing facility in Saltillo, Mexico, with room for significant expansion.

Increasingly, end customers are willing to pay a premium for solutions featuring “Infinitum Inside.” Our OEM partners are successfully leveraging this differentiation to achieve higher close rates and command greater margins.

In short, we believe we have crossed the chasm—introducing breakthrough technology into a traditionally conservative sector. We are now ready to scale our go-to-market team substantially and are seeking team members who are passionate about rapid growth, eager to learn, and excited to tackle the challenges ahead as we make this journey together.
