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 don’t just review plans — you solve problems, optimize systems, and make complex designs actually buildable.

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.

What You’ll Do:

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.

What Makes You a Strong Fit:

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.

Compensation & Details:

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.

Why ROXBOX:

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

How to Apply:

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.
