Principle Mechanical Design Engineer

The anticipated start date for this position is April 2027, subject to organizational scheduling and operational requirements.

Hanford Tank Waste Operations & Closure (H2C) leads the nation's largest and most complex radioactive waste cleanup effort. Every day, our teams work to safely remove, treat, and dispose of 56 million gallons of legacy tank waste at the Hanford Site in Richland, Washington.

When you join H2C, you become part of a team dedicated to creating "The Solution Today for a Better Tomorrow." Guided by our Vision, Mission, Values, and Behaviors, we work together with integrity, innovation, and accountability. We empower our workforce, encourage continuous improvement, and celebrate achievements as we make measurable progress toward tank waste cleanup and long term site closure. At H2C, your work has a meaningful impact—today and for future generations.

H2C is seeking a Principle Mechanical Design Engineer to support the Direct-Feed Low-Activity Waste (DFLAW) mission within the Design Engineering
- Mechanical organization. This role provides mechanical engineering expertise to support design, analysis, evaluation, and stewardship of mechanical systems across DFLAW operations, projects, and facility modifications. Mechanical systems may include process systems, structural/mechanical components, mechanical equipment, and system interfaces essential to safe and reliable operation.

The Principle Mechanical Design Engineer is an individual contributor who collaborates with other engineering disciplines, operations, projects, and maintenance to ensure quality, compliance, and effective design integration.

• Provide engineering support for mechanical system design, application, analysis, testing, operation, and maintenance associated with DFLAW facilities and supporting systems.
• Assume responsibility for mechanical engineering aspects of assigned tasks or projects, including development of design inputs, specifications, calculations, and technical evaluations.
• Prepare and review engineering documents such as calculations, drawings, specifications, technical reports, manuals, procedures, and design packages.
• Conduct field walkdowns to evaluate installed conditions, identify mechanical system issues, and recommend corrective actions or design improvements.
• Investigate engineering problems, develop alternatives, evaluate solutions, and provide technical recommendations.
• Apply mechanical engineering principles to improve system reliability, reduce costs, enhance performance, and ensure design compliance with applicable codes and standards.
• Develop or support preparation of technical scope, cost estimates, and schedules for engineering tasks.
• Problem-solve complex technical challenges using sound engineering judgment, established methods, and adaptation of design alternatives.
• Coordinate work with other engineering disciplines, operations, maintenance, construction, procurement engineering, and project teams to ensure integrated solutions.
• Ensure engineering deliverables meet technical, safety, and quality requirements and align with approved processes and configuration control expectations.
• May serve as a lead on specific engineering tasks and mentor less experienced engineers.
• Execute assigned work with minimal oversight, demonstrating ownership, initiative, and accountability.
• Maintain strong technical problem-solving capabilities and contribute to continuous improvement within the Design Engineering
  - Mechanical organization.
