You Will:

• Act as a technical authority for erosion control, geosynthetics, and stormwater solutions across heavy civil, DOT, commercial, and land development projects.
• Influence project outcomes early by engaging in pre-bid reviews, pre-construction planning, and design-assist conversations.
• Provide hands-on field support including jobsite evaluations, installation guidance, troubleshooting, and solutions optimization.
• Build executive-level relationships with contractors, engineering firms, developers, and regulatory stakeholders.

• Identify and develop new market opportunities through strategic outreach, industry involvement, and relationship-based prospecting.
• Serve as the industry leader between customers, internal teams, and manufacturing partners to ensure alignment and execution.
• Maintain discipline use of CRM and reporting tools to forecast opportunities, track activity, and provide insight into market trends.
• Provide leadership with clear, actionable intelligence on competitive positioning, pricing dynamics, bid strategy, and emerging risks.
• Representing the organization at industry events, conferences, and associations meetings as a recognized professional voice.

This role isn’t just about sales, it’s about influence.  You’ll have high visibility across the organization and the market.  With Autonomy to grow your territory, you’ll have robust internal resources and vendor partners behind you.  This isn’t a short-term transactional position; it’s a long-term opportunity to make a lasting impact.  If you’re ready to lead, shape outcomes, and build something significant, this is your stage.

• Experience in erosion control, geosynthetics, stormwater, civil construction, or site development
• 3+ years of sales experience, preferably in account management or business development
