ROXBOX – Turning Steel Boxes into Game-Changing Spaces

You don’t chase chaos—you eliminate its causes.

You thrive in a system that runs like a well-oiled machine. You see waste before others even know it's there. You’re not just a manager of people—you’re a builder of processes, habits, and culture. And you’re ready to bring that mindset to a modular production floor where speed, safety, and quality depend on smart systems and strong leadership.

At ROXBOX, we build custom modular solutions out of shipping containers and steel-framed components. We’re looking for a Lean-minded, process-driven Production Manager to lead our Houston manufacturing facility into its next phase of growth. If you’ve ever said, “Let’s fix the process before we automate it,” we want to talk to you.

• 5+ years leading production teams in modular, prefab, or construction environments

• Familiar with Lean Manufacturing concepts like 5S, standard work, and waste reduction (bonus: experience supporting CI teams or implementing field-level improvements)

• Strong with BOMs, shop drawings, labor tracking, and pull-based scheduling

• Comfortable facilitating stand-up meetings and standardizing work

• Adept with digital tools—spreadsheets, dashboards, and project tracking systems

• You earn trust through clear communication, consistent follow-through, and data-driven decisions

• You don’t just hit KPIs—you build the systems that make them inevitable

• Task & Schedule Owner – Keep production aligned with daily/weekly takt goals. You’ll know what’s due, who’s on it, and where adjustments are needed to stay on track.

• Flow Facilitator – Design and maintain a smooth production flow across trades and workstations. Eliminate friction, downtime, and double-handling.

• Waste Watcher – Spot and help eliminate non-value-added steps. Provide feedback to the team when you see friction or flow problems.

• Labor & Time Tracker – Monitor hours by task, by team member, and by job. Use real-time feedback to optimize crew balance and reduce overages.

• Material Readiness Gatekeeper – Ensure builds never start without the materials, tools, and information required. Manage inventory with precision and collaborate upstream to prevent delays.

• Drawing Verifier & Feedback Loop Closer – Review construction drawings, flag disconnects early, and collaborate with design and estimating to close the loop between plan and reality.

• Lean Execution Leader – Reinforce standard work, visual controls, and 5S practices. Support CI initiatives and help implement process changes led by others.

• Culture Builder – Foster a culture of accountability, improvement, and pride in workmanship. Support and coach your team in daily 5S, safety, and performance huddles.

We’re not your average shop. We build one-of-a-kind structures with the efficiency of a product line. You’ll be joining a leadership team committed to smart growth, Lean principles, and building a culture where everyone contributes to smarter, more efficient work.

If you’re ready to do more than manage builds—and instead, help build a world-class modular manufacturing operation —apply today.

Bonus Qualifications (Not Required, But Awesome):

• Lean Six Sigma certification

• Experience in container-based or steel-framed modular construction

• Familiarity with pull systems, value stream mapping, or Hoshin planning

• Submit your resume & cover letter explaining why you’re the perfect fit

• Complete our 5-minute Culture Index Survey:
