Build More Than Projects. Help Build the Future of Infrastructure.

At Ralph L. Wadsworth Construction (RLW), we don't just build roads, bridges, water systems, and mission-critical infrastructure—we build careers. As part of the Sterling Infrastructure family, RLW has been delivering some of the most challenging heavy civil projects across the Western and Central U.S. for more than 50 years.

We're looking for an experienced Master Plumber who brings both technical expertise and a strong quality mindset. This role will serve as the plumbing subject matter expert on large-scale construction projects while helping ensure installations meet all code, quality, and project requirements from start to finish.

If you're the type of person who takes pride in doing things right the first time and enjoys being a trusted resource in the field, we'd love to talk with you.

Why Join RLW?

2. Water and wastewater facilities
3. Transportation and roadway projects
4. Heavy civil and structural concrete construction
5. Large-scale industrial and infrastructure developments

Your Expertise Will Be Valued

This is more than a plumbing role. You'll be a key technical resource helping drive quality, compliance, and successful project delivery.

What You'll Do

1. Serve as the plumbing subject matter expert on assigned construction projects.
2. Review plumbing installations to ensure compliance with applicable codes, specifications, and project requirements.

4. Identify deficiencies, develop corrective action plans, and verify completion of corrective work.
5. Coordinate with project managers, superintendents, subcontractors, inspectors, and owners.
6. Review drawings, specifications, submittals, and installation plans.
7. Support project commissioning, testing, and turnover activities.
8. Maintain quality documentation, inspection reports, and project records.
9. Mentor field personnel and help promote best practices in plumbing installation and quality control.
10. Ensure all plumbing work is performed safely and in compliance with applicable regulations and standards. Oklahoma plumbing work requires appropriate state licensure and code compliance.
