MANAGER - PART SALES & OPERATIONS

Diamond C Trailers LLC
Mount Pleasant, TX Full Time
POSTED ON 9/16/2026
AVAILABLE BEFORE 11/15/2026
PART SALES & OPERATIONS

In 1985, Mike and Kim Crabb founded Diamond C with a small team and a big dream. Over the years, the company has grown significantly, now employing over 900 team members. Diamond C remains a family-owned and operated business, with a strong emphasis on our foundational “Do Work, Love Strong” culture, which is based in Mt. Pleasant, TX.


We are unwavering in our commitment to more – more process improvements, more sustainable manufacturing, and more opportunities for our team. Our purpose is to fuel the growth and success of our team members, customers, and community. We're dedicated to being a positive force for change and using our expertise to make a meaningful impact on our community abroad. This role is located in Mount Pleasant, TX 75455


Purpose:

The Manager of Parts Sales & Operations is responsible for the daily leadership, growth, and operational efficiency of the Diamond C aftermarket business. This is a "Builder" role designed for a leader who can manage a P&L, understands warehouse and supply chain operations, and - most importantly, proactively drive revenue through dealer and digital channels.

The successful candidate will transition the team from a reactive "support" function to a proactive "sales" function, ensuring that Diamond C parts are the first choice for our 200 dealers and their customers.

Sales Management Emphasis

  • Sales Team Leadership: Lead and coach the internal parts sales team (call center) to move beyond order entry. Train the team on upselling, cross-selling, and consultative "Value" selling (e.g., selling the long-term benefit of an OEM hanger kit over a generic alternative).

  • Dealer Revenue Growth: Proactively manage the Diamond C dealer parts network. Develop "Recommended Stocking Lists" to ensure dealers have the right mix of high-turn parts on their shelves to capture local "walk-in" sales.
  • Sales Conversion & Metrics: Own the conversion rate for inbound inquiries. Implement sales-based KPIs for the team, moving the focus from "average handle time" to "average order value" and "conversion percentage."
  • Marketing Collaboration: Work closely with the Diamond C Marketing team to develop Parts Sales - Go To Market strategies and "Sales Toolkits" that dealers can use to drive their own aftermarket revenue.

Key Responsibilities

1. Sales Operations & Team Development

  • Recruit, train, and manage a high-performing parts sales and support team.

  • Implement a sales-driven compensation or incentive structure for the parts team to reward revenue growth and service excellence.
  • Standardize the "Sales Discovery" process for inbound calls to identify broader customer needs before the order is closed.

2. Inventory, Distribution & Drop-Ship Strategy

  • Collaborate with operations, ensuring inventory accuracy and "Speed to Ship" standards.

  • Drop-Ship Execution: Actively manage and expand the supplier drop-ship network to reduce Diamond C’s inventory carry costs while maintaining 24–48 hour delivery standards for the customer.
    • Expand and optimize product offering
  • Forecast inventory needs based on trailer production trends and seasonal demand cycles to avoid "Stock-Outs" that kill sales momentum.

3. Digital & E-Commerce Sales

  • Manage the online parts catalog as a primary sales channel.

  • Ensure product descriptions, photography, and "Related Products" (upsells) are optimized to drive digital conversion without human intervention.
  • Monitor online customer journeys and remove friction points in the checkout process.

4. Financial & P&L Management

  • Own the Parts Sales P&L, with a focus on improving gross margins through strategic sourcing (working with Supply Chain) and optimized pricing.

  • Manage the department budget and provide multi year revenue forecasting to support organizational planning.

Qualifications (Managerial Focus)

  • 7 years of progressive leadership in parts, aftermarket, or industrial sales/operations.

  • Proven track record of managing a sales-focused program or internal sales team.
  • Experience in distribution and fulfillment, specifically leveraging 3rd party or supplier drop-ship programs.
  • Solid financial acumen; ability to read a P&L and identify "leaks" in margin or excessive operational spend.
  • Strong collaborative skills to work with Production (for part availability) and Sales (for dealer alignment).
