About Cambrian Innovation

Cambrian Innovation designs, builds, and owns industrial water and wastewater treatment systems under long-term Water and Energy Purchase Agreements (WEPAs). We own and operate infrastructure on our clients' sites and charge per gallon of treated output. That model means we carry the financial and operational risk on every project we develop, so the decisions made in early-stage development matter for the next 20 years.

About The Role

This role sits at the intersection of technical development and commercial execution. Half the job is winning the work; the other half is defining what we're building. You will support active sales pursuits as a technical resource on client calls and site visits, and you will own FEL-1 project development from signed MOU through initial design and EPC procurement.

The right person moves between a sales conversation and a treatment train review in the same week. You don't need to be a pure salesperson or a pure engineer. You need to be both, and you need to know when each is required.

What You'll Do

Sales Support — Join client calls and site visits as the technical voice of the sales team. You can walk a CFO through a WEPA structure and discuss a proposed treatment train with a plant engineer in the same meeting. You understand the sales process and help move deals forward by answering questions credibly, identifying technical risks early, and giving clients confidence in Cambrian's approach. You will then need to interface with counsel and ensure that the commercial contract is aligned with the technical scope and business arrangement.

FEL-1 Project Management — Once a deal reaches MOU, you own the development timeline. You run site visits, coordinate data collection, manage third-party contributors, and track every open item. Clients hear from you regularly with clear status. Nothing waits because it wasn't assigned.

Initial Design Development — Starting from influent characterization, flow rates, and discharge requirements, you develop treatment train options, screen them against capital and operating cost targets, and produce a design basis sufficient to support an EPC RFP. You know what works and why, and you can defend a recommendation to a client's own engineering team.

EPC Procurement — You write the RFP, manage the bidder list, run the technical review of responses, and deliver a clear recommendation to the project team. You understand what an EPC needs to price a job accurately and where gaps in scope create cost overruns later.

CRM and Pipeline Discipline — Deal status, milestone dates, open items, and follow-up commitments stay current in HubSpot and ClickUp. The team pulls your project status without asking you.

What We're Looking For

  • Five or more years of experience in industrial water or wastewater treatment, with hands-on involvement in developing treatment concepts from a blank page. Food and beverage, energy, or chemical sector experience is relevant; greenfield or new-facility project experience is a strong plus.
  • Demonstrated ability to run a pre-FEED or FEL-equivalent process: site data collection, treatment train development, initial cost framing, and handoff to EPC procurement.
  • Genuine comfort in customer-facing settings. You have been on sales calls, walked plant floors with clients, and navigated technical questions in real time. You know how to build credibility with an engineering team and trust with a business stakeholder.
  • Experience with ClickUp and HubSpot, or comparable project management and CRM tools, and the discipline to keep them accurate.
  • B.S. in environmental, chemical, or civil engineering. P.E. is not required.

What This Is Not

This is not a field operations role. Cambrian's operations organization runs commissioned systems. This role ends at a successful EPC handoff.

This is not a technical support role that rides along on sales calls. You are a full participant in the commercial process, and your technical judgment shapes both the deal and the project that follows it.
