Sales Rep – Scaling Sustainability at Critical.

About Critical.

At Critical., we’re rewriting the narrative for plastic waste. Our flagship material, Cleanstone, is made from 100% recycled plastics and is leading the charge in sustainable building materials. Think of us as the “Apple of green design and circular building materials”—cutting-edge, beautiful, near carbon neutral, circular, and transformative. We started Critical. to be good tīpuna (ancestors) so generations beyond us can thrive. We’ve spent the last 6 years developing world-leading technology to transform hard-to-recycle plastics into beautiful, durable materials that accelerate the built environment toward circularity.

As a Māori company, we seek to uplift the mauri (life force) of te taiao (the natural world) and partner with iwi Māori and indigenous communities to deploy our technology and products worldwide.

The Role

We’re growing fast — inbound leads are flowing quickly. We’re looking for a part-time Sales Rep to help reduce the sales cycle, respond promptly, and close deals with architects, designers, and brands who want to use Cleanstone.

• Manage ~20+ active deals weekly in Pipedrive
• Respond to new leads within 8 hours (first call + email)
• Qualify projects, send samples, and lock in review calls
• Prepare and send quotes within 24 hours
• Follow our proven playbook to maintain momentum (no deal idle >
