Columbia Energy
Senior Mechanical Designer
Location: Richland, WA (Position based 100% onsite) Company: Columbia Energy & Environmental Services Salary Range: $80,000 - $120,000 (DOE)
About Columbia Energy Columbia Energy & Environmental Services, headquartered in Richland, WA, is a well-established small business with a 30+ year legacy of delivering practical, cost-effective solutions to clients in the nuclear, defense, energy, and environmental sectors. Originally founded to support nuclear cleanup work for the U.S. Department of Energy at Hanford, we've grown into a full-service engineering, fabrication, and project execution firm serving both federal and commercial markets. Our team is collaborative, forward-thinking, and focused on precision, accountability, and results. We pride ourselves on integrity, agility, and technical excellence-and we're looking for professionals who share these values.
Why Join Columbia Energy? At Columbia Energy, you'll work in an environment that values initiative, continuous improvement, and smart problem-solving. As a small but growing company, we offer the opportunity to make an immediate and visible impact. This is a chance to take ownership of your work, see your designs brought to life, and contribute meaningfully to the success of complex, highly regulated projects.
Position Overview We are seeking a Senior Mechanical Designer to support the development of piping systems and mechanical equipment from concept through fabrication and installation. This position plays a key role in translating engineering concepts into buildable 3D models and detailed fabrication drawings, working closely with engineers, project managers, and shop personnel.
This is a hands-on, detail-driven role for someone with strong experience designing for fabrication and familiarity with ASME standards, manufacturing processes, and equipment layout.
Essential Responsibilities & Duties • Create piping and mechanical system designs in collaboration with project teams. • Develop 3D models and fabrication-ready drawings using Autodesk Inventor and AutoCAD. • Apply ASME and client-specific drafting standards. • Translate redlines, markups, and engineering comments into drawing revisions. • Produce accurate, shop-ready packages based on real-world fabrication constraints. • Support ECN/DCN processes and shop redline updates. • Coordinate with engineers, project managers, and fabrication staff throughout design lifecycle. • Contribute to solutions for field installation and constructability challenges.
Required Qualifications • High School Diploma • 2-Year Degree in Drafting, Mechanical Design, or Engineering Technology • 12+ years of mechanical design experience • Proficiency with Autodesk Inventor and AutoCAD • Must be a U.S. Citizen (due to federal contract requirements)
Preferred Qualifications • Experience designing equipment and piping for DOE or Hanford Tank Farm projects • Working knowledge of fabrication and machining processes (welding, cutting, tolerances) • Familiarity with Creo, SolidWorks, SmartPlant, or other 3D modeling tools • Prior experience preparing ECNs/DCNs and fabrication drawing packages
Key Success Attributes • Detail-Oriented: Produces clean, buildable designs with accuracy and clarity. • Collaborative: Works well with engineers, project managers, and shop staff. • Adaptable: Thrives in fast-paced projects with shifting priorities and real-time changes. • Problem Solver: Brings practical thinking and hands-on solutions to the table. • Ownership Mentality: Sees work through from concept to fabrication.
Core Competencies • Technical Precision • Critical Thinking • Communication • Reliability • Professional Integrity
Working Conditions • This position is office-based in Richland, WA, with occasional collaboration with fabrication and field teams. • Standard business hours with occasional flexibility depending on project needs.
Columbia Energy is proud to be an Equal Opportunity/Affirmative Action Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
