Carrier Development Manager

About Riverstone Logistics

Riverstone Logistics (RLX) is a big and bulky supply chain powerhouse delivering seamless final mile, middle mile, warehousing, fulfillment, and storage solutions through a nationally integrated platform.

Founded in 2017 by five partners who believed logistics could be built around something bigger than moving freight, we began with furniture delivery and grew into a nationwide provider serving complex supply chains across the United States.

We are a purpose-driven company. We exist to use our God-given talents and opportunities to love our neighbors, serve our communities, and improve our industry. That purpose shapes how we lead our teams, how we partner with our customers, and how we take ownership of every delivery.

Our people, who we call Extra Milers, bring genuine integrity and care to every mile. If you lead well, communicate with clarity, and want your work to mean something, we want to meet you. If you’re looking for a place where people genuinely matter, you’ve found it.

**Our corporate headquarters is moving to Rock Hill, SC in July 2026. To be considered, candidates must be willing to work onsite in Rock Hill, SC five days per week.**

Role Overview

Mission: The Manager, Middle Mile Carrier Sourcing sources Full Truckload middle mile Motor Carriers to haul RLX contracted freight, then hands those relationships to Operations to manage. You build the capacity that keeps our network moving by finding, connecting with, and establishing partnerships with the right Motor Carriers, then passing them off cleanly. This is a player-coach role, weighted heavily toward personal production, that also develops one less experienced Carrier Sourcing Representative.

Core Objective: To grow and protect RLX's middle mile capacity by sourcing mid to large Motor Carriers for our contracted freight and by developing the next Carrier Sourcing Representative. You do this by working the top of the funnel with discipline, opening doors inside larger trucking organizations, handing qualified Motor Carriers to Operations without friction, and helping make RLX the 3PL of Choice among the Motor Carriers who contract with us.

Who You Are

You are an experienced sourcing professional who finds capacity others cannot and builds trust with Motor Carriers quickly. Motor Carriers are independent business owners with other options, and you understand that the relationship is a business-to-business partnership, not an employment one.
You know how to get into a larger trucking organization. You get past gatekeepers, identify the real decision makers and stakeholders, and open the door to new business. You are comfortable targeting mid to large Motor Carriers by power unit count for contracted, high-volume work, not spot quotes or one-off projects.
You lead by doing. You carry your own sourcing targets at a high level and, at the same time, show one less experienced Representative how to do the same. You set the standard through your own production and hold your Representative to it with honest, direct communication.
You stay close to the freight and logistics markets. You track capacity, pricing, and market news, and you bring that intelligence into your sourcing strategy. You work well across internal departments and you protect the arm's length posture in every interaction.

Key Characteristics We Are Looking For

• Crafty Sourcer: You find capacity where others cannot. You bring unique solutions to hard-to-cover lanes rather than relying on the same predictable channels.
• Door Opener: You navigate larger trucking organizations with confidence, getting past gatekeepers, identifying decision makers, and establishing contact for new business.
• Relationship Builder: You earn trust through consistency, follow-through, and honest communication. Motor Carriers see you as a genuine partner, not a transaction.
• Player-Coach: You produce at a high level yourself while developing one less experienced Representative through daily example, clear direction, and shared targets.
• Market Aware: You understand what is happening in the freight and logistics markets in terms of capacity, pricing, and relevant news, and you use it to source smarter.
• Cross-Functional Connector: You partner naturally with Operations, Compliance, and other internal departments to move sourced Motor Carriers cleanly into active lanes.

Essential Duties and Key Responsibilities

Motor Carrier Sourcing

• Source Full Truckload middle mile Motor Carriers across Dry Van, Flatbed, Box Truck, and LTL to cover RLX contracted freight.

• Qualify Motor Carriers against RLX contracted service standards, then hand the relationship to Operations cleanly so accounts launch without friction.

Required Qualifications
