MEP Design Engineer - Own the Systems Behind Modular Builds

ROXBOX - Turning Steel Boxes into Game-Changing Spaces

As our MEP Design Engineer, you'll be the systems thinker who ensures our modular builds perform as brilliantly in the real world as they look on paper. You'll play a key role in bringing order to complexity and helping our teams deliver value without waste.

You speak architecture, engineering, and fabrication. You move comfortably between drawings and the real world. You're energized by technical challenges, coordination puzzles, and bringing order to fast-moving projects. If that sounds like you, you might be our next MEP Design Engineer.

ROXBOX is pushing the boundaries of modular construction, turning steel-framed and container-based structures into high-performance buildings. We're looking for a hands-on, detail-obsessed MEP Design Engineer to support our design + production teams and tighten the loop between concept and fabrication.

• Review, redline, and coordinate mechanical, electrical, and plumbing drawings for modular projects
• Translate client/architectural requirements into efficient, code-compliant engineered systems
• Work within Revit + Bluebeam (and occasionally jump into drafting) to clean up and clarify MEP deliverables
• Collaborate closely with internal design, estimating, and shop teams to eliminate gaps between design intent and production reality
• Provide technical input on value-engineering options and modular system best practices
• Support compliance reviews to ensure systems meet applicable building codes and performance standards
• Capture lessons learned from each project and feed improvements back into our design standards and workflows.
• Act as the bridge between architects, engineers, and fabricators - translating requirements into clear, buildable solutions.

• 5+ years of MEP design experience in building systems engineering
• Bachelor's degree in Electrical or Mechanical Engineering (or related discipline); Mechanical background with strong electrical knowledge considered.
• Familiarity with plumbing and electrical systems and working knowledge of HVAC fundamentals.
• Strong focus on manufacturability - able to bridge design intent and production reality.
• Proficient in Revit and Bluebeam, with excellent technical documentation skills.
• Experience in design-build or modular/prefab environments is a strong plus.
• Ability to self-direct, own deliverables, and proactively flag issues.
• Thrives in collaborative problem-solving environments and enjoys improving processes project by project.

• Base salary range: $90,000-$110,000 DOE
• Full-time position with medical, dental, vision, and PTO benefits
• On-site in Houston, TX (77041)
• Reports to: Principal Architect, while collaborating with the Production and Quality Manager to ensure tight coordination between design and build.
• Monday-Friday schedule with occasional coordination needs outside normal hours

We operate with a Lean mindset - empowering our people, solving problems at the source, and continuously improving how we deliver value. If you're ready to put your MEP expertise to work shaping the future of modular construction, we'd love to talk.

• Work on innovative modular construction projects across diverse industries
• Join a tight-knit, technical team that values precision and ideas
• Make a real impact in a role where engineering decisions directly affect buildability
• Help shape the future of off-site, design-build construction

• Submit your resume and brief cover letter. In your cover letter, please include:
  • The most satisfying system you've ever designed or worked on, and why.
  • One process improvement you've made (or would make) in how MEP systems are coordinated on modular or design-build projects.
• Complete our 5-minute Culture Index survey:
