Rehlko is seeking a Senior Design Engineer to lead the design and execution of custom enclosures and fuel tank systems for engineered‑to‑order generator solutions.
This role is ideal for a mechanical engineer with strong CAD expertise who enjoys owning complex projects from concept through production and collaborating across sales, manufacturing, procurement, and global engineering teams.
In this role, you serve as the technical authority for enclosure and fuel tank solutions—balancing customer requirements, manufacturability, cost, and schedule in mission‑critical power applications. The Senior Design Engineer will work closely with cross‑functional partners while remaining deeply hands‑on in design, analysis, and problem resolution
Work Mode: Hybrid-3 days in office
Location: Mosel facility at N7650 County Rd LS, Sheboygan, WI, 53083

Responsibilities:
Lead the mechanical and CAD design of custom enclosures, tanks, and accessories for industrial generator
Own designs from initial customer requirements through engineering release, fabrication, and production support
Create and maintain complex parametric models, assemblies, drawings, and specifications using Creo

Identify risks, propose solutions, and make data driven engineering decisions
Support and participate in continuous improvement initiatives that streamline custom order and engineering processes
Occasionally interface with customers and global engineering teams
This is a role for an engineer who sees the problem, owns the problem, and solves the problem—from concept through execution.
You will:
Tackle complex, ambiguous design challenges where requirements evolve and trade offs matter
Diagnose and resolve real production issues involving sheet metal, weldments, fit up, sealing, vibration, and thermal performance
Investigate non conformances and field issues, determine root cause, and implement corrective design actions
Develop practical solutions that work on the shop floor—not just in CAD
Balance speed, cost, quality, and performance while maintaining engineering rigor
Take ownership when issues arise and drive them to resolution, coordinating across engineering, manufacturing, and suppliers
Required Qualifications
Bachelor’s degree in mechanical engineering (BSME) from an ABET accredited program plus 5+ years of mechanical engineering experience
Hands on Creo CAD modeling experience (required)
Experience designing industrial or engineered products
Ability to independently manage multiple concurrent engineering projects
Strong written and verbal communication skills
Proven ability to collaborate in a cross-functional, global engineering environment
