If you're looking to make an impact at a stable, forward-thinking company where your work is tangible and valued, Welker may be the right fit.

We are seeking a Mechanical Design Engineer who thrives on owning projects from concept through production. In this role, you will design and customize pressure-containing equipment and mechanical systems for a range of industrial applications.

This is a hands-on engineering position where your designs are not just theoretical—you’ll see them built, tested, and used in real-world environments.

• Design and modify pressure-containing equipment and mechanical assemblies using Solid Works
• Interpret customer specifications, datasheets, and industry requirements to develop compliant design solutions
• Perform engineering calculations (pressure design, stress analysis, tolerances, material selection)
• Ensure designs meet applicable codes and standards (e.g., ASME, PED, IECEx, CRN)
• Create and release detailed drawings, models, routers, and Bills of Materials (BOMs)
• Support product testing, certification, and technical documentation
• Collaborate cross-functionally with manufacturing, sales, and quality teams
• Apply design for manufacturability (DFM) principles to improve production efficiency
• Troubleshoot design issues and contribute to continuous product improvement

• Bachelor's degree in Mechanical Engineering (ABET-accredited)
• Strong proficiency in Solid Works or similar 3D CAD software
• Familiar with ASME codes and pressure-containing equipment design
• Understanding of machining, fabrication, and assembly processes
• Strong attention to detail with a proactive, ownership mindset

• 3+ years of mechanical design experience in oil & gas, energy, or industrial manufacturing
• Experience with:
  • Valves, regulators, or pressure control equipment
  • Instrumentation or electrical components
  • Engineering calculations
  • Validating designs
  • Familiarity with certification standards (PED, CRN, IECEx)

• Work on real, built products from concept to production
• Be part of a collaborative, cross-functional engineering team
• Gain exposure to both legacy product improvements and new product development
• Join a stable, family-owned company with long-term growth

• Competitive salary (based on experience, education, and potential)
• Health, dental, vision, life, and long term disability insurance
• 401(k) with company match
• Paid time off and paid holidays
• Tuition reimbursement

• Must be authorized to work in the U.S.
• Must successfully complete a drug screen, physical, and background check

If you're ready to design impactful products and see your work come to life, we’d love to hear from you.
